I don't have the link, but I remember the article well because I wrote off the LEAF as a future player on that day.

For current Leaf, the Bolt and Tesla have better battery liquid cooling systems; if the Leaf keeps the same air cooling system, I may've to get a used Tesla.
A large fraction of Nissan batteries are losing 20% capacity a year.edatoakrun wrote:Tony828 wrote:Considering the new 2018 Leaf.

Liquid cooling is only cost effective if If you have a very expensive pack, or in instances when a flammable battery pack (tesla) makes it a safety requirement.
As battery costs continue to fall rapidly, the added expense and efficiency penalty of liquid cooling makes even less sense than it did in the past.
Seven years ago, The LEAF was (and still is) a far superior BEV for most buyers, for having the "better" conductive battery cooling design.
It would be disappointing if Nissan, in a misguided attempt to satisfy common stupidity, handicaps the Gen two leaf with liquid cooling.
A large fraction of Nissan batteries are losing 10 - 20% capacity a year. The 80% depreciation in 3 years is in large part due to the crappy battery pack.SageBrush wrote:edatoakrun wrote:Tony828 wrote:Considering the new 2018 Leaf.
