Excellent, and spot on. In our 4 yrs driving EV, we’ve charged at 2.1kWh (10 amps), via the granny charger. Plug in at around 6.30pm, and unplug around 7/7.30am…giving 95/100 miles in the depths of winter, and 130/140 odd miles in the warmer months (Tesla Model 3 SR+).
@Sp_75-76 5 місяців тому
The one small problem is that you cannot fully make use of time of day charging, so you are paying considerably more than if you had your own wall charger. For instance I get about 28 kWh overnight at 9p per kWh whereas on a granny charger I would only get 10 - 12 kWh, the rest (assuming you had a time of day tariff) would be at the full charge I do agree however it would take a long time to recoup the outlay on the charger, so it might not be a consideration
@usefulrandom1855 2 місяці тому
@@Sp_75-76 Im in this position. 9 miles per hour on the granny charger is 36 per night on my current 9p tarrif for 4 hours. I only do about 5 miles per day so its more than enough. I think I will charge 2/3 nights per week. I would like a 7kw though but as you say it would take years to recoup the cost, it might even fail/need changing again before I do haha. I do have a 50kw charger about 100m away from me but its 65p per KW so not ideal. I will use it only if I need I think. Intelligent octopus is 7.5p for 6 hours but again its a marginal saving my non intelligent tarrif and I would not recoup the cost in a meaningful timeframe.

Had my MG4 for 3 weeks now, I’ve done 1000 miles in it, but my annual mileage is around 6-7k. I use the 3pin plug for most of my charging, making use of my solar panels during the day. The adapter draws around 2kw, that gives around 8 miles per hour. I did a 10 hour test which gave 30% and 83 miles but importantly there was no discernible heat in the plug, wall socket or cable. Really enjoying the down to earth format of your videos.
@davetakesiton 10 місяців тому
Hi Gary, hope you are enjoying your MG4, I have heard great things about them. Great readings. Over the last 3 months of making videos I have taken hundreds, probably thousands of photos with the car plugged into a huge variety of chargers. Any figures I use in my videos are always actual readings supplied by Tesla in the mobile app and on the car display while charging. My 3 pin waterproof socket has 16 amps available, but my battery management system seems happier only taking 10 amps. So I typically get 10A x 243V and 4mi/hr showing. If you get 8mi/hr that's great, you are faster than a Model S, Dave
@garyhill9723 10 місяців тому
@@davetakesiton I’ve been taking pictures of the gom before and after charging every charge to try to get a handle on consumption. For the ten hour test I used a socket monitor to see the charging losses. The socket showed 1900-2250w as the consumption (total cost £7.35 although that didn’t take into account the solar contribution), the car’s charging monitor showed the battery getting 1.7-2.0 kw, and the gom added 83 miles.

I am currently using a 13 amp socket. There are two reasons why I am getting a home charge point. First, is safety, as others have pointed out, it can cause a 13 amp socket to overheat, I haven't had issues but I feel I am taking a risk. Second, if you do go on a longer journey, it is nice to be able to arrive home with a low state of charge and be able to top it back up again off-peak. At the moment I will often make sure I arrive home after a long trip with around 50% because of how long it takes to top up on the granny charger, plus it may have to do some charging on peak. If you are renting then you can still get the £350 grant. The £1000 7kW charge point soon pays itself back on a cheap overnight tariff.
@garyhill9723 10 місяців тому
I did the same calculation but based on my mileage decided to stick with 13 amp. 6000 miles per annum, = 1500 kWh say £450, at cheap rate £150, so 3 years to cover the cost of the charger install. If I factor in higher daytime rate, I can time shift washing/drying but not oven/cooking the payback period extends. In addition my home came with solar panels which generate around 3200 kWh per annum.
@davetakesiton 10 місяців тому
Very true MistyMu, my very reason for installing a 7kW home charger, only I often arrive back with 4% SOC and need it back up to 90% within my off-peak window overnight. Yes, it has paid itself back many many times over, Dave
@vincelemon6343 2 місяці тому
This is true about safety. All the professionals say to NEVER USE a granny cable to charge EV long term as it isn't safe for the house or the car. 13 amp leads should only be used in an emergency to get you home but never as a permanent charging solution.
@rhiantaylor3446 9 місяців тому
Dave - you imply we can either use a 13a socket to feed a granny cable or spend ~£1k for a dedicated EV charging point. A third option is to have an electrician fit a dedicated 6mm power feed to a Commando (blue) switched socket and then use a 32a version of the granny lead that uses the plug version of the same Commando connector to charge at up to 7kw. (The latest regs may require an earth rod to supplement your existing earthing provision, connected to the 32a socket). This 32a granny lead can then be taken to multiple locations provided they each have the associated 32a socket available. You could also obtain a short adapter cable from a commando socket to a Schuko plug for use at up to 16a in many European countries.
@davetakesiton 9 місяців тому

Thanks for posting this video. Full of excellent advice and guidance. Just one correction I would offer is that not all EVs have the ability to monitor SoC and/or charge speeds remotely. I drive a 2019 Kona and there was no app for this year model so no remote telemetry/control. My wife's 2021 Zoe does have an app so your comments are spot on for her vehicle. We have a Wallbox 'charger' which is set to scheduled charging overnight for 4 hours which is the only "smart feature" we use. Allows me to override the schedule without having to go out to my Kona to press buttons....

@@davetakesiton Our charger (ICS) has a 'virtual fuse' on the fuse board where the tails terminate (and a CT clamp around those tails) so it monitors the incoming load and throttles the charger if we're going to go over the 80 amp physical fuse. I set a 'safe' 15% anyway so we get about 14a which still works for overnight charging.
@MarkHewitt1978 2 місяці тому
I have a PHEV, which I originally looked at getting a proper charger for - I even bought an Eero one then changed my mind and sent it back after being messed around by the installer. I eventually got a EV specific outdoor socket from Screwfix which comes with a safety cutoff and got it installed by an electrician. Total was around 50 quid for the socket and 150 for the electrician. However I do only run it at 6A which takes 7 hours to charge the 9kWh battery, and that is good enough for me. An additonal expense was a Type2 to 3pin charger from Argos and that sits outside all the time (under a plastic box with a plant on top) with the plug being in a holder on the fence.

Good advice there. We went with a home "charger" recommended by our electrician. The Smart bit as you say is of dubious use, but I did want one running the OCPP Protocol so it could 'talk' to my home automation software. We could have got away with the 3 pin (our use case is the mostly < 200 miles a week), but we were having loads of electrical work doing anyway. Happy we have it, but definitely the view - when we bought the car - was very much you must have a home charger, however you use your EV. Especially if living in a rural spot, there are NO > 7KW charges within 20 miles!
@davetakesiton 10 місяців тому
Yes, Alex, I regard chargers a bit like my home smart meter display. Once the novelty wears off, it sits in a cupboard, only ever coming out to check my rate when EDF announces a price change, then it's back in the cupboard. Shame about this "you must get a home charger" attitude. Many people who commute just 10 miles a day simply don't need one. Also my outdoor waterproof socket is rated at 16A at the consumer unit, and I tell my Tesla it has 16A but it only ever draws 10A. It's like its protecting the circuit and plug and I'm happy to let it, safety first, Dave

@sciencetestsubject 10 місяців тому
When I bought my Ioniq 4 years ago, I used the granny cable for 2 years before installing a home charger. What is noticed is that normal outdoor sockets (I'm in NL so shuko) don't like these high loads of extended periods, I had to replace the socket every year. A more advanced home charger has some benefits compared to the granny cable. First is energy monitoring, so you can actually see what the cost of charging is. Next is protection of your main fuse(s), when you are charging and turn on the cooker, you may overload your main fuse. More advanced home chargers temporarily reduce power, so not to exeed the your main fuse rating. Last benefit is diversion of renewable energy, some can keep your electric meter from spinning when it's sunny.
@davetakesiton 10 місяців тому
Yes and no. On a personal note, if a socket overheats and needs replacing I would 100% get an electrician in, not just replace it. An outdoor socket if properly installed is good for much more than 13 amps without overheating. Trouble is, many are not properly installed and just piggy back off some other circuit which means if the car is already maxing out the power and several other things are turned on in the same circuit it can cause problems. Get an electrician, tell him or her you will be charging an EV and let them do it right. Home chargers are always connected on a dedicated circuit with its own proper spec cable and RCD. But the car should decide. My app screenshots show clearly my car is set to 16amps, my the car recognises the Tesla charger being used and resets the limit to 10amps, safety first and always, Dave

@migsteele 15 днів тому
By ‘fancy features’ do you mean life saving pen fault protection? And if you are using an external socket, the only reasonable way to do so, is to have a dedicated radial circuit with a type a RCD. I can imagine loads of people will add a socket as a spur off of their ring main or into their ring main. Putting a considerable additional load. 13amp sockets are not robust enough for a continuous load above 8-10amps, you can often reduce this within the car but it increase charge times even further and without doing so risks a very melty socket. You need a very specific setup for the 13amp socket to be considered safe for every day use, and you have not highlighted these. This risks giving license to people with out-of-date electrics, adding a spur off their ring main and risking fire.

A useful alternative to a wall box is installing a 16amp socket. It’s relatively cheap to run a suitable cable to an external 16amp socket. Then change the plug over on your granny cable. The only advantage with a wall box is that they’re WiFi enabled, thus allowing you to remotely control the charging

Certainly my type 2 cable lives under the car's bonnet, so it's always there. But just how often is one likely to need a granny charger in an ordinary day's motoring, seriously? I'll take it with me if I'm staying away overnight just in case something goes horribly wrong with my overnight charging plans and I have to plug in at my host's house (never happened yet), but for day-to-day driving with an expected return well within the range of the car, what's the point? My granny charger sits on a shelf in the garage right under the socket it's plugged into, about a metre away from the car's charging port when it's garaged, and it stays there (other than for overnight trips). Maybe I'm wrong, but the less one pulls the plug out and in the socket the better, I think.

@@SirHackaL0t. I actually use my granny charger routinely as I don't have a wall box. (Rapid charger 400 yards away at only 30p per unit, then top up with the granny.) I don't want to be unplugging it all the time, because I don't want to put excessive wear on the pins and connectors. So it stays plugged in in the garage most of the time, because I'm always going to be back long before I get low on charge. However if I'm going on a trip where I'll need to charge away from home, I'll put it in its bag and stow it in the boot, just in case. I haven't needed it - the friends I've stayed with fortuitously have public chargers within walking distance of their houses, so I haven't neded to impose on their electricity supply. But suppose there had been a problem with these chargers, I could have done that. I think the chances of being unable to access a working public charger so that you need to beg for help where you find yourself are very low these days. And in fact your best bet in that situation would be to crawl in turtle mode to somewhere people have wall boxes and ask for the use of one of these. A fellow EV driver will probably be happy to help out for a tenner. But if push absolutely came to shove and you found yourself at an isolated farm or cottage, having the granny with you could be a lifesaver. I know it's really, really unlikely. But how many times (in a previous life) have I run out of petrol because for some reason I didn't have that 5-litre green can in the boot? At least twice.
@moragkerr9577 10 місяців тому
I've taken some stick for sticking by the granny charger, but it suits me. I have heavy-duty metal-casing 13A sockets in my garage, on a separate circuit with a circuit breaker. The plug never gets hot, and as it's 1.5 metres from the car's charging port, I don't need an extension lead. In the normal course of events my mileage is easily covered by what I can get with the granny lead. My electrician had a look at the setup when he was at the house for another job and said it was absolutely fine. If I get home on low charge, I'm lucky. 400 yards from my house there is a rapid charger that's capable of putting 65% charge into my battery in 54 minutes - the maximum time allowed on the charger. And the price of the electricity is about the same as my home electricity tariff - for the past few months it's actually been slightly cheaper, then mine went down a bit. I came home at 4% once (about nine in the evening), pulled straight into the charger and set it going, walked home and put the kettle on and had a cup of tea, and walked back less than an hour later to a car sitting at 68%. Drove to my driveway, unloaded the car, ran it into the garage, and put it on the granny charger. According to the car's app, it was at 100% and the cells balanced before 3 am. When the weather gets horrible I'm more likely to give the five-minutes-each-way walk a miss and just let the granny charger do the lot. But if I do need the car filled up from very low in five hours or so, the opportunity is always there. I had assumed that when I got an EV I'd naturally get a wall box. Two people in my road - with very similar houses and garages - have got them. But even with the £300 grant I'm eligible for, I'm struggling to justify the expense. Even if the public charger price goes up, I NEED it so seldom that it wouldn't really be an issue.
@davetakesiton 10 місяців тому
you quickly develop what works for you and charge as little as possible away from your cheapest option. Probably the majority will never need to charge at a public charger, ever. I chose a home charger for work as, like you, I would often return home with 3-4% and needed it back up to 75-90% by the morning within my 10 hour off-peak window. Only a 7kW home charger could do that, works for me, Dave
@moragkerr9577 10 місяців тому
@@davetakesiton As you say, you develop what works. I very seldom come home as low as I did that day - well, never in fact, but I had been out on a joyride, the cheap charger I had meant to sample turned out to be broken, and I realised I could get all the way back with a (very) little to spare, and didn't give Gridserve at Abington my money! But since I've got a public charger in such a useful location, and I hardly ever drive to the limit in a day, I'm not seeing £1000 for a wall box as being worth the money - at least not at the moment.

One point not mentioned is efficiency. A Tesla for example, when powered up will consume about 200W. If on a granny charger, that is a 200W overhead on a 2400W input. ~8% loss. However, 200W on a 7kWh charge is only a 3% loss. Because the granny charger will take substantially longer, the total losses mount quite significantly.

Great video thx. I'm currently waiting for a ohme charger to be installed at home. And would probably only need to charge once a week with the miles we do. Currently thinking about moving over to the octopus energy tarif, as our supplier is a flat 31p per kw with no offers for ev owners. We did our first long trip with our ev last Friday, 256miles. Used electroverse app to plot the route and it then sent it through to Google maps, for us to follow on the car. Found that zapmap only does scheduled long 40min to 1hour stops to charge, where electroverse does the quick charge and go, like your video on charging explained. On zapmap with the 3 long stops would have taken us 7 and a half hours to do the journey. With electroverse 5 quick stops it was 6 and a half hours. 2 more stops, but an hour quicker. The only issue we had was between the apps to plot the route, and then sending it to Google maps. Google maps kept trying to reroute us back to an old charger we already left behind. And we had to close the apps down, and redo the whole route to get it to work again. We also fount that half the chargers on electroverse, would not show on zapmap. Almost as if the apps has not been updated with new chargers in a long while. If possible could you do a video for us non tesla owners, on best app to use for route planning, and quick charging stops. And maybe show a demo, as we found it a bit of a struggle. Thank you.

We looked a this. Probably not! But there's something comforting about having the charger there, ready to go knowing you can get a decent charge reasonably quickly. Switching to one of the Octopus Tariffs (4 hours overnight 7.5p kwh) means we charge about every 7-10 days currently. It does make the car extremely cheap to run, but I don't think we'll get back to the install cost.
@davetakesiton 10 місяців тому
Thanks Susanna, my point exactly. Everyone is different, but at 60 miles per day, you could be well within range of a 3 pin waterproof socket, unless you only have 4 hours off-peak cheap rate, or you go long distance at weekends. There is no set rule or payback time. I do a much higher mileage than average and got my money back from savings in about 3 or 4 months, but far more importantly, it allowed me to use my car at the cheap off peak rate for work, which I could not have done on a 3 pin, Dave

Thanks very much for this. I've been thinking of getting an EV because, having been retired a couple of years, my current 5yr old diesel - with just 15k on the clock - is sat on the drive most days, apart from the odd trip to the shops or into town. I thought a home charger installation cost would have to weighed up in the equation....but this info has nudged me further the EV way. One thing I've often wondered, are the charger cables lockable? What's to stop the local....(let's call them just 'scallywags' to be polite) unplugging them and running off with your cable in the night? (we have an 'open' driveway and the plugged-in cable would be on open view....)

if you don’t have an outdoor socket if you’re thinking of one for an EV I’d suggest getting a dedicated circuit added - to make sure its not overloading an existing ring you may have spurred off. At that point I’d probably go for a proper wall charger if you’re getting a dedicated circuit not much difference to make that 32A capable vs 16A
@davetakesiton 10 місяців тому
Right MrKlaw, the advice to me was to have a dedicated circuit and mine is protected by a 16A RCD at the consumer unit. Interesting to note that I tell My Tesla it has 16A but it always defaults to 10A, like it is protecting me and the circuit and I'm happy to let it, Dave
@chrisbowser 10 місяців тому
Interesting take Dave. I have a PHEV which means I need to charge each day. Previously I used an outside socket which I installed myself (it is the type where you plug it in inside the house with a fixed rcd plug). I then used my granny each day. In the end I went for a zappi home charger why? 1. Having to unplug and put away the granny after every use was a faff as it’s easily stealable I didn’t want to leave it connected all the time. 2. With intelligent octopus I can charge for 7.5p between 23.30 and 5.30 they don’t support charging with a granny. 3. Safety, the new consumer unit added by the ev charge installer also includes surge protection, this means in the event of a fault with the house supply the car is protected. The final point being many people do not pay and electricians to install an outside socket (and one that complies with the EV regs would be a lot more than £100) but drape wires out of bathroom windows or worse on an unwound extension lead.

@SirHackaL0t. 10 місяців тому
A few addendums… DC is what the battery uses. AC is what your electricity supply provides and the on board charger converts it to DC for the battery. The bag can contain an EVSE which has the 13A plug. This is normally the one that has a unit in the middle of the cable to talk to the car. A tesla version can have the plug changed to match the sockets of whichever country you are in or are visiting. Other EVSE chargers may vary. The other cable is used when out and about to connect to public AC chargers that can range from 3kW to 22kW. In the UK a 13A socket is designed for 10A or 2Kwish power being drawn over a long period of time. Kettles etc get away with drawing higher current because they are typically only on for a few minutes and the socket doesn’t get chance to heat up by much. Pulling 10A for hours at a time can lead to overheating if the socket isn’t maintained properly which shows by burning marks around the pin holes. This will eventually lead to a fire. If you want to use the ‘granny’ charger as they are colloquially known, on a continuous basis then it’s best to get the 16A commando socket and appropriate adapter for your EVSE to match. This will allow 16A to be drawn resulting in a faster charge. Do not use a 16A commando socket to 13A plug to get faster charging as it will lead to a blown fuse or a fire. Your image of a 7kW public charger is actually a DC rapid charger that also has an AC socket. It might be better to show an actual AC public charger instead to avoid confusion. Whilst you can get away with using the 13A plug isn’t not a good idea to do so on a permanent basis due to the risk of a fire from a dodgy socket or even the wiring heating up running through your house if it’s not of sufficient size. A commando socket is far cheaper than a dedicated charger and an electrician can install one easily for not much money with it’s own dedicated RCBO in your fuse box. I hope this helps. :)

@davetakesiton 10 місяців тому
not sure why people keep stating 13 amp socket and 10A continuous. Plug a 3kW kettle and a 2.1kW toaster into the same socket in your kitchen and turn them on. I just did, works perfectly without getting hot. It would be impossible to draw 5.1kW even for 1 second if the socket was limited to 13A or 10A. Sockets have no fuse or restriction, they are designed to be wired into a ring main circuit protected by a 32 amp RCD in the consumer unit, therefore each socket happily and safely can take 7.5kW. The 13 amps refers to the plug which does have a fuse, maximum 13 amp, which gives around 3kW. There is no such thing as a 13 amp socket, Dave

I mainly use the 3 pin Granny Charger. Plugged into a 13amp 3 pin outdoor socket on the corner of my home on the driveway. The reason is something else ... I only have a total of 30amps supply to my rural property, so cannot have a charger which would draw 40amps and most normal houses have at least 60amps - the preference is 100amps on a non-looped supply. An electrician can explain it all. For me, this is fine ... I can charge at work for free (if I go into one of our offices) and my employer (NHS) offered me a free home charger with my lease (but of course, I had to decline). One other slightly good thing is that I am on a fixed tariff of 16p per Kw night and day - this never went up like everyone else. If I am doing a lot of miles then I'll pick an Ultra Rapid BP Pulse nearby, charge to 80% and then top off overnight at home if I need to. I did all this research for months before I went for a leased EV and find that in reality, over the 8 months I've had an EV, my overall monthly motoring costs are £50 per month less than running my previous Diesel Jaguar which averaged 55mpg.

Some house wiring may be old and if the house has had alterations done by a kitchen fitter or some one who does DIY that is not an electrician, there's a chance this is a fire hazard. A lot of homes have the old type AC RCDs, when you plug in your EV to a 13A socket there's a chance of this blinding the RCD preventing it from working under fault conditions. Yes the wall chargers are expensive but they have a lot of safety features built in for a very good reason. (Additional RCD protection, PEN fault protection, Load management ect.)

I am currently using a commando lead with a (at the time) £150 Chinese portable charger; mainly because it was all I could afford at the time; however, 1 year into ownership of my s/h KIA Soul, I AM questioning if getting a "proper" wallcharger is such a good idea. I cant find any information about their capabilities to set a charge current limit other than when installing; yet I know that charging beyond 80% is best done at "trickle charge" levels, and that overall, the slower the charge, the less damage is being done to the battery cells. My Chinese mobile charger allows me to set a number of different current limits, 10, 16, 20, 24, and 32 amps; do any of the wallchargers allow the same level of control ?? Currently, (lol), I usually charge at 20 amps, as my little 27 KWh battery doesnt take that long to do a 20-80% top-up; but once a month I trickle charge to 100% at 13 amps. At 7 years old, my Soul shows a battery health of 88-92%, depending on which app I use; and I would like to keep it as healthy as possible; the estimated range shows as 94 miles (summer), 78 miles (winter), and I have managed over 70 miles of country roads at normal road speeds, and finished with an estimated remaining range of 32 miles. As an ex industrial sparky, I fitted my own 32 amp socket, using 16mm armoured cable; almost certainly "illegal" under current government regs; but if I was considered competent enough to have my equipment fitted to HM nuclear subs and NHS Research labs, I am damned if I am paying good money to get a certificate qualifying me to a much lower standard.

I don't think you have your maths right here. If you have a 3kW EVSE that provides only 4 miles of range per hour, then a 7.5kW EVSE will only add 2.5 times that range, which would be 10 miles per hour, not 21 miles. The voltage is the same, but 2.5x the current means 2.5x the power delivered , hence 2.5x the range . I live in the USA, and the basic 110V, 10A charger adds about 3 miles of range per hour to my C40 (1.1kW). Switching that same portable EVSE onto a 20A, 230V outlet allows it to deliver 16A maximum current (3.7kW), which gives me about 10 miles of range added per hour on a vehicle that gets just 3 miles per kWh. I'm assuming that a UK EVSE is going to deliver about 10A at 230V with a 13A fused plug (about 2.3kW) which should put you in the 7-10 miles per hour range, depending upon how efficient your car is. Many of the smaller EVs in the UK get 4-5 miles per kWh, so I'd be quite surprised if you were down at 3 miles per hour with this setup.

I'm not sure I'd want to select a 13A mode on a multi output current portable EVSE with a UK 13A socket, as it's right on the limit of the plug's rated current. The wiring behind it is probably rated for 20 or 30A, but it's limited by the 13A plug.

The app says 10 amps and the display says 3 or 4 miles per hour, it wanders occasionally. My 7kW home charger says 32 amps and delivers a remarkably stable 21 miles per hour. At an 11kW public fast charger I get 33 or 35 miles per hour.
@jeffcranmer5374 Місяць тому
@@davetakesiton 10A at 230V is 2.3kW. if you're getting 21 miles per hour at 7kW, but only 1/7th of that rate at 1/3 the power, something is very non linear and probably faulty. You should be getting about 7 miles per hour at 10A, 230V. My Volvo gets 10 miles per hour at 16A, 230V, 7 miles per hour at 10A 230V, and about 20 miles per hour on the 30A, 230V charger at work. I only get 3 miles per hour at 10A, 110V.
@jeffcranmer5374 Місяць тому
Looking at it another way, you're putting 2.3kW into your car, but only 1kW is getting into the battery. The other 1.3kW is getting turned into heat somewhere, probably within your car. That's enough excess heat to make me nervous.

10 amps 3 pin is better for the battery. I was quoted £1500 and thats 5000 miles of electric
@steveharvey2001 10 місяців тому
3kW is a lot more than 3 miles per hour. Closer to 10 miles per hour for cars that do over 3miles/kWh
@davetakesiton 10 місяців тому
Not on my car, Steve, for my charging video series you can see the app screenshots, and is recorded as flicking between 3 and 4 miles per hour, nothing to do with miles per kWh, that’s using power not gaining it, Dave

Either your car calculation is incorrect or it's not pulling the KW you're thinking. My leaf gets about 8 miles for 1 hr of granny charging pulling around 2.4kw. There are some losses but that's usually below 10%. Charging losses are not that big. The math does stack up. I.e a car with 50kwh battery will do about 150 miles if you can get 3 miles /kw. Note most granny charges especially supplied by the manufacturer do not exceed 10 amps.
@watchtheskies 10 місяців тому
@@davetakesiton So your car is only accepting 1kwh of energy per hour from your AC 3kw per hour supply? If this is happening when the battery is nearly empty? then there is something seriously amiss with your AC charging system?
@Iainab5 10 місяців тому
@davetakesiton I don’t follow your logic of putting 3kw into your car but only adding 3-4 miles in an hour. That must mean you are only getting 1 -1.3 mls /kw when driving, or there are huge losses on the 3kw you are drawing from your house. I would check you are actually drawing 3kw.

@@Iainab5 Hi Iain, the speed the car accepts and charges at has nothing whatsoever to do with the miles per kWh I get while driving. They are totally unrelated. If it did, I would get a different range from the car if I charged at a 3kW, 7kW 50kW 150kW and 300kW. I don't. A full battery always gives me the same range. The power of the charger, shown either as kW or miles per hour plugged in, merely dictates how slowly or quickly it reaches the limit I have set. i.e. if I set 100% SOC, then a 3kW rate will take many hours, a 300kW rate would take much less time. But both would still reach 100% and both would give me the same range. I get a display on my mobile app and my car display that tells me the Volts, the Amps, the kW speed, time remaining and the miles per hour that I am adding while it is plugged in, live as it charges. I have hundreds of photos of these using different chargers. These are not my figures, they are Tesla, so I believe them. If you need more, let me know in the comments and I can put a collection of readings together as a video, Dave

Without a home charger you also have more losses. So in the long run it's better to your wallet to make this investment

Had my EV for 2 years now. Only ever charged on 13A at home or, if needs must, public chargers en route. The biggest change for me was... planning. When I first got the car (Peugeot e-2008) it said 205 miles range. Now typically 170-180 miles at 100%, with 150 real world miles. You just need to a) know your intended journey distance b) the state of charge and c) where the suitable chargers are if you might need to recharge (as I do frequently for the 190 mile journey to visit my father). Range anxiety has only once been an issue, which was overcome. Just. EV charging has never been a problem without a home charger (which I cannot get). And, yes, I will get another EV. No question about it, other than the replacement will have a longer range.

Dont use the 3pin plug regularly, it is only for occasional use. Burns out my 13amp sockets. Get a proper ev charger.
@iscadean6038 7 днів тому
This is rubbish. I use a 3 pin plug and have done for two years. Plug is always cold and I plug in overnight. Car draws 10 amps/8miles per hour.

This is poor advice. The "humble" 3-pin socket is not suitable for long-term charging of an EV; they tend to over heat and degrade quite qickly. If a 3kW charge at home is sufficient for your needs, then you should fit one of the new EV-rated 3-pin sockets. Depending on individual circumstances it is possible that it would have to be installed by a qualified electrician. As a minimum, get the installation inspected. Is it worth the risk of voiding your house insurance? If you can afford an EV you should budget for a wall charger.
@jeffcranmer5374 Місяць тому
Will a 13A socket or plug degrade if it's subjected to a 10A EVSE current? I don't see any immediate reason why this would happen, as nothing is being operated above its rated level 10A at 230V is 2.3kW, which should add about 7-10 miles of range per hour, or 84 to 120 miles in a 12 hour overnight charge for a typical EV. Given that the average person drives 20-30 miles per day, that's adequate for most people.
