kolmstead said:So averaging 0.5% loss per month. 60 months, 30% loss, which is right in line with what a lot of cars did with their original batteries. Whether or not that is better than original battery depends on where you are. Phoenix cars probably lost about 1% per month on original batteries.

I have had my 15 S exactly 18 months now and have 17263 miles on it.
Gids: 289

Ambient temp in garage, low to mid 40s F.

kolmstead said:The degradation reported by Evoforce, sksingh and others has convinced me that it is not worth $6500 to replace my battery next fall. Conditions in Ridgecrest are not quite as intense as Phoenix, but my battery lost about 0.6 percent per month. And there's the other consideration... that right about the time I'd be buying a new battery, the 60 kWh Bolt and maybe Leaf 2 should be available. Why invest in obsolete (24 kWh) technology?

I don't think anybody knows that yet. 15's are holding up well in places with great temps but not everywhere.Nfuzzy said:...if there is some reason the replacement packs don't seem to hold up as well as the new 15 leafs?

My 15 doesn't seem to be doing so well.

At any rate, we'll have folks reporting how their lizard batteries are holding up after two summers. On the original Leaf battery, the screaming didn't begin until second summer.

Nissan has said on numerous occasions that they weren't going to use TMS. OTOH, the e-NV200 will apparently have some cooling for QC: http://insideevs.com/heres-nissan-employs-active-air-cooling-e-nv200-battery-pack/Stoaty said:Source?Evoforce said:I am not happy that they still have not added cooling to their 60kWh battery that is due to come to market.
I don't see anything about Leaf 2.0 not using a TMS. The lack of a TMS isn't working out very well for the Lizard battery based on reports here. Until information is released on Leaf 2.0, we don't know what Nissan will do. The rest is speculation.GRA said:Nissan has said on numerous occasions that they weren't going to use TMS.

Informed speculation - Nissan has been pretty adamant that they weren't going to use a TMS. It would be a 180 for them to say now that they've decided to use one (even though they almost certainly need it).Stoaty said:I don't see anything about Leaf 2.0 not using a TMS.

kolmstead said:A couple of years ago, OrientExpress, who seems to have pretty good ties with Nissan, stated that the objective of the car companies was to have cars become consumables just like cell phones, with about a 3-year lifespan. Buy or lease it, drive it three years, and recycle it. A battery that only gives about three years of usable service fits right into that business model.
Once we start seeing rapid improvements in battery capacity, that trend will reinforce the rapid obsolescence of older BEVs. So the real issue is unrealistic expectations from those of us who used to keep our cars eight or ten years. We just need attitude adjustment!
