That is an EU LEAF which means it has RapidGate SW adjustment that we don't get so yeah, it would be better...

So on the 40 KW leaf do you get slow down even on the first Chademo session?

Just let the battery cook more with increased battery degradation, great solution, right? Not here in U.S., as Nissan's battery
replacement liability would be a financial nightmare, besides the bad press.

If you buy a BEV without TMS and expect to drive intercities in the U.S., realize the negatives!

Yep

People are focusing on the DCFC limits because that affects them today but accelerated degradation can be anticipated for these owners because of their use case, irrespective of whether the Europe SW "fix" is applied. Then we will have a new round of "I was never told !!!" whining.

Looks like they are realizing the negatives. No details yet, but you heard it here first.

I think that was his point.

Battery life at high temperatures is improving. For amusement, Nature Energy has an article of a LI-ion battery with better cycle life at 60C than at 25C.

I thought Dave was passing gas, errr ... passing on a rumor that Nissan will include TMS in some future car.

The rumor cycle is starting early, so I'll add my own: **Eventually** Nissan will get a clue.

Actually fairly impressed today. Car was outside today in 98+ degree heat all day (9:30 - 5) and the temp bar moved beyond the 1/2 way point where it started. I get the feeling the battery is insulated sted, which might be awesome come January here, but makes heat dissipation slow in summer.
