After an hour of fast charging I had only gained about 60% charge and the battery temperature gauge was pegged to the first high temperature mark.


Did the temp bars reach the highest temp they can indicate, or just the first red bar? The term "pegged" comes from gauge needles hitting the little metal peg at their maximum reading, and is used to indicate a gauge that is 'maxed out'. This temp issue is real, and it's serious, but we need to avoid hyping it in order to remain credible. Seeing a reading at the first red bar (out of how many in the 2018?) isn't as bad as seeing all of the temp bars showing. Or is there just one red bar now?


The temp bar moves generally in chunks so there is a delta for any position but the "3/4th" bar happens between 120 - 125 º

It shouldn't be this hard to get a straight answer. It still sounds to me like the "pegged" temp bar gauge was actually NOT at its maximum reading, but was showing just the first of several red bars. That isn't good, but given the propensity of the Gen I Leaf to regularly show one or more red bars while connected to QC and afterwards, it isn't going to raise any alarms at a dealership.

The "3/4th" mark IS the first high temperature mark...

So, you saw 123 degrees F in your battery yesterday? The max I saw in the logs you posted was 110 degrees F and that was for the third quick charge session. I realize this was probably at the beginning of the QC session per Loren's instructions, but I didn't see where you mentioned 123 degrees. That would seem newsworthy.

This was yesterday...err Friday. Hard to keep track of days when I don't do anything but laundry, dishes, pizza and Netflix... :shock: It was a "minor" edit to the temp tracking logs... :)

Holy wow, 123F in the Pacific Northwest in April?!

Arizona cars in July should be interesting. I wonder if QC will drop even lower than 22 kW in that sort of environment?

E-plus and TMS can’t come soon enough. Maybe this explains the glacial US 2018 Leaf rollout; they’re just killing time until the real car arrives in the fall.

I think that cars outside of the Hot states will be the most egregious cases, because few people will be expecting the cars to act as if they are being driven in Arizona, when in fact they are being driven in Washington State. Or Upstate NY.

AZ will be the canary -- if they even bother to sell LEAFs there anymore. If not, then Texas or the CA desert

Perhaps we should have a poll: when will the report of the first bar drop be posted ?

If we've learned nothing else from years of "battery tracking", it's that the data doesn't matter until you get it from a car in AZ/TX/FL (and maybe Southern CA). I suspect that L3 charging will be no better than L2 on a hot day in TX...which is why I would wait for Leaf 2.5 (with the bigger battery pack and active cooling).
