They are not failing and if the driver takes a chillpill and restricts fast charging to twice a day, it will be fine for 300k more miles. Or sells it to some individual who mostly drives 10k a year. Point is not to continue to overheat rear pack.

@@gelisob A swollen Lithium cell is never good.

Makes sense to me. It would be very expensive to replace those. And the car already has allot of miles. Since it sill works fine, they probabaly want to see how much life they can squeeze out of them

That's normal for a taxi. In the 1970's I knew a taxi driver who did about 1,200 miles per week in Winter, and more in Summer. Even at Winter averages, that's about 60,000 miles per year. That Nissan is 2 years old. A fleet taxi, which is used by more than one driver, can easily exceed 100,000 miles per year.

@@RWBHere Driving airport transfers in the early 2000's we did 15k km a month for 3 months and 10 k a month in the other 2 of our 5 month winter. January I did 20k km. my record day was 1086km. Mosty french autoroutes, but always mountains and snow at the end.

With Nissan's record so far on 24, 30 and 40kWh Leaf's I really fear for the 62kWh models too, I would not buy them. Other EV manufacturers do not see this failure/degradation rate. 120k miles is good but realistically half of what a well maintained ICE car can do, and rapid charging daily is not unusual for some use cases, so batteries need to be more rugged here for sure.

This was aprrox £900

This car needs a new pack. They will gonna get this car back in shop, other modules are almost dead too in rear stack.

£900 repair bill after 120k miles. That's impressive and I'd dread to think how much an ICE car would have had in repairs and servicing in that time.

@@geoffreyhallam6228 Let's pick a popular Nissan, the Quashqai 1.6 diesel, 12K service intervals, at quick fit are £99 interim £168 major, say 5 of each = £1335 That does not include brakes which an ICE car uses way faster then a BEV or any other wear and tare items like a clutch kit, most modern ICE have a duel mass flywheel, for this one it is about £480 for a decent branded clutch and flywheel kit (LUK) If used as a taxi it would not be far off replacement by 120K miles.

@@pashko90 but Taxi Driver is sweating his assets. It's his business to run. Not too many busy taxi drivers at moment.

We have a low mileage 2012 Leaf, and so far had to replace the heater module at about £300 but nothing else. What issues have you had and are early Leafs unreliable (battery aside)?

@@chrishyde1216 Hi I needed my ptc heater replaced nissan quoted 3500 quid. Recently parking module went 2000 quid. Also just got a repair fixed just before warranty about 3 years s ago it was a major had a courtesy car from Nissan for 3 weeks. It was the electric unit fail guy from nissan if it was not under warranty would have cost 4500 quid. Thankfully it failed 1 month before my warranty expired it was covered under 5 year battery cover. The only way it is still on the road is that I managed to source salvage parts and know a good garage. Also the usually with EVs 12 volt battery fails thats another long story

Check out EVs enhanced NZ

Probably takes lots of reading over time

SOH was indicated as 87% on Leaf Spy in last few secs of video.

I saw that too, if the SOH is the same, how does the range increase, that steps above my knowledge so hopefully someone can answer.

@@SheepShearerMike because as noted on the first leafspy shot, the pack of cells that were not balancing would not have been used for power by the car so less range, dunno why they didn't show the range on the gom before and after. And the soh applies to the health, not the range it would only show a loss of range if it got to below 85% soh where it would lose a bar

Hi, we use second hand modules.

@@Jamesandkate any chance of a video of whats inside the old packs when you open them? great video shame you aren't based in the NE you could do my leaf lol

Yes we can. We're just putting one in our own eNV200. We're also adding a UBEX range extender. Should be a couple if weeks 👍🏻

@@Jamesandkate that's brilliant. What's the best way to get in touch with you for more details please? Regards Phil

That sounds interesting. But are you using a salvaged battery? Unfortunately, where I live, in Cape Town, salvage batteries are not readily available

Hi. Bonita an easy fix. Best way is to simply replace the PDM. Second hand they're about £700. Make sure you get a 6.6 not a 3.3kW replacement 👍🏻

I think its just cold outside in this area. It will changed and gets recalculated when battery pack is +10-15 degree celcius.

the air between the cells would actually lead to one of them overheating more. With no air the heat dissipates in the pack. and you can't remove one cell, the pack voltage would drop as the cells are in series

How many sells are there in these packs?

@@grahamjohnson4702 It's configured in 96s2p so 192 cells.

@@grahamjohnson4702 4 cells in each module I believe

while it was off and I presume all the packs are the same, I wonder if jiggling around into a different area might have prolonged the life of them, I know that in mobile phones and other small devices you are supposed to change the batteries if they bulge as they could burst or explode so if I was the owner i'd ask about changing them as well, I know he said they were fine, but for how long?

YES . Battery was out already . Greedy owner !

yes, this pack is dead. It needs capacity matched rear stack or complete cells replacement.

I think a lot of those I-Mievs and Leafs will in the future have the pack replaced with cheap solid state cells. Less affected by temperature and much higher energy density.

eBay

It is.

This video shows a bit uncommon issue when cells or modules are failing. In most packs the degration happens in all the cells so you can't do much about this. Other than change the whole pack of course.

Losing 1 bar is not a reason for concern, after 6 years. Do make a note at what mileage that was when 1 bar was lost. Then use normally until the second bar loss - you may expect it to be 20-30k miles or 2-3 years later, unless you are rapid-charging it all the time.

@@matijasokola3879 many thanks i just was gutted when it happened lost about 8 miles in range

Was thinking that a bit of thermal management and it would not have been in there

A diesel taxi with 120k miles would not doubt have required a lot more maintenance work in the same time period

@@GlynHudson other than oil filter air filter fuel filter I know many a diesel that's done 300000 odd with out any real manitanance but my point was this is a leaf issue not a ev issue plus if it was a diesel it would of given some one cancer by now I eggsagerate but you get the point

Not many fail actually. How many engines are uneconomic to repair?🤣

@@zenbudhism what's your criteria age and mileage wise because many a BMW diesel has needed thousands of pounds to repair the injector's

Only need to remove bolts, no setting timing , draining fluids etc.

@@zenbudhism True, but you can change a head-gasket without jacking the car up, and without special lifting equipment. Swings and roundabouts! I reckon the difficulty level is similar.

Hi. They only have 4 cells per module, but the SOH is based on overall degradation of all modules. Replacing these two modules will have little effect on the whole pack SOH.

Yeah it's just was asking a guy who I bought two modules off and he said that technically they have 4 cells in the module but there made up of two in one cell or something one going parallel or something I don't know lol anyway I got a brand new module off him which measures 13volts across which isn't fully charged and the second hand one reads 16volts which he said is charged does the voltages sound OK cheers Martin.

To say it doesnt work is quite a sweeping statement, as it all depends upon how the car is used and the climate it is used in. To be fair to Nissan, they may well have underestimated the problem of overheating/degradation - there wasn't much previous evidence to go on, in terms of ev's. To fit a thermal management system may well have necessitated a redesign of the car body at massive expense and most likely why Nissan decided to work on the battery chemistry instead, being the potentially cheaper option. Considering the cash I had to shell out to keep my combustion engine car on the road at that mileage - the cost of fixing this was reasonable.

@@TheLongonot62 I don't think I was being unfair though. If you're going to sell a car in a number of markets with fast charging capability the product needs to function in those environments. It smacks of that'll do. The most alarming part of the video is the battery bulge. That's horrendous.

120K miles in 2+ years, they won't cover that.

0:27 - 120k miles?

But it would have qualified before then as the bus says 79% max plus before the 100,000 would have clearly been under a defective pack 8 year

Only if you rapid charge it four times every single day

Nissan warranty on the pack is 8 years or 100,000 miles which ever is 1st ! So at 119k miles , its out of warranty !

@@JonathanPorterfield Thanks, that clarifies it.

It wouldn't be covered by warranty as the normal warranty is 8 years OR 160,00 KM which is approx 100,000 Miles as this car is over that the battery is out of warranty by quite a bit.

Yeh, I wish! My 11 playe Leaf has 85,000 on the clock, but only 52% SOH, which being a 24kWh pack, gives a whole 30 range in the UK this winter!

@@SheepShearerMike You might find that only a few battery cells need replacing, so the repair might not cost as much as you expect.

One day work and one used module (since u cannot buy those as spare part from dealer), maybe less than 2k?

@@ht3880 Thx. Wow that's pretty messed up for a recent model vehicle to have the level of damage it does. Nissan have clearly not fixed much with their EV batteries.

@@JeanPierreWhite it's because the driver used it as a taxi. A regular person who doesn't quick charge 4 times a day would probably not run into this problem. Nissan will fix this temperature problem with the Ariya.

@@ht3880 Nissan have fixed their battery problems before, supposedly. This is evidence they have made very little progress in ten years. The idea they will suddenly fix the issues overnight is very optimistic.
