Re: 40 kw-hr battery in 2016 leaf

Keep I mind I'm in a very hot area. Depending on where you are, the 40 may last you a very long time.

I just don't buy the idea they are equal to thermally managed packs. Not where I live anyway.

The data from the Geotab Study does not support your conclusions:

2017 Leaf SOH at 2 years 8 months - 94.7
2016 Leaf SOH at 2 years 8 months - 93.9
2015 Leaf SOH at 2 years 8 months - 89.0
2014 Leaf SOH at 2 years 8 months - 89.6
2013 Leaf SOH at 2 years 8 months - 92.1

It would be terrific if we could get the underlying data but not possible. I think the latter years are more robust simply because there were more Leafs around than for the early years, but that's a guess on my part. FWIW my 2017S is at 95.6 SOH after 2 1/2 years.
These cars were all in the same location...?
The study consists of cars in Arizona, Rhode Island, New York, Nashville TN, Florida and Lincoln, Nebraska. Other areas may open up later.

Is that 2 years 8 months since manufacture date or from purchase?

Would make a big difference on mine.

Based on the 40 battery topic the average for 2018s here is around 92 to 93% currently irregardless of mileage or age.

Then given the sensitivity of Leaf packs to climate, the study is worthless. You could reshuffle the locations for different Leafs and get different results for each generation pack.

Dan, I assume the start date is when the car enters the study.

Leftie, I don’t understand your comment about “reshuffling”. The study is not being manipulated by anyone and represents aggregate results of the cars studied. There is no way for me to massage this data. If someone has better data, I’d love to see it. If the results go against “conventional wisdom”, refute it with better data.

I mean that the Leafs from hot climates will degrade faster, while those in colder climates will degrade more slowly. Unless they used an equal number of cars from each climate (cold, temperate, hot) for each generation pack, the results will not be useful. I don't think the results were manipulated, just not useful because of this.

LeftieBiker that is my view as well. The study is another set of data but not very discriminating.

I'm pretty convinced it is a 40 kw-hr battery. Drove 132 miles, battery at 20% still. Leafspy is still reading crazy.

Good to see that other people are saying 40s will replace the bad 30s. I gave the wrong leaf model, not sure where SE came from, but I had the 30 kw-hr.

It is pretty amazing to go from 60-70 mile range to ~160.

CaliLeaf do you have any more charging/range experience with since the 30 to 40 swap. After reading all weekend I did not find the expected range difference in when using the 40 kWa pack with a 107 HP motor than the stock 147 HP motor in Gen 2 Leafs. Thanks

The motor is actually the same in both cars. The inverter was upgraded to provide more power to the motor in the 2018+ Leaf. Since little time is spent at full throttle in either car by the typical Leaf driver, range should be about the same in typical driving.

That was the info that I was searching for but had not found. So a 40 kWh battery at full throttle in a Gen 2 Leaf will be a tad quicker of the line than a 2017 Gen 1 Leaf with the same battery but basically the same performance and current drain in day to day driving?
