Is or will there be a TSB for this sent out?

Lesson learned for me then. If I get another EV it will be one with active battery thermal management. My Leaf Plus is leased, so I have 3 years to see how much capacity is lost.

Apparently new news for the 62 KWh. I wonder if Nissan is going to do anything about it, since it wasn't adequately communicated to prospective buyers, and they sold it as a much more useful vehicle than it is, even bragging about 100 KW fast charging capability. Retrofitting liquid cooling...

Yes, it was the car's temperature readout. I'm not sure where the sensor actually is, but if the car sits, it goes up quite a bit.

Yeah, at high ambient temps it just can't shed enough heat. I didn't notice any derating due to temperature on the way back, but I was driving carefully in order to get all the way back (I think 55-65 MPH on the freeways. I'll check when I get home to be sure).

Temperature profile from LEAF Spy on my 62KWh LEAF on a round trip to Santa Clarita, CA from Ridgecrest, CA. Outside temps were 100-105. Definitely a problem with pack heating both driving and DC fast charging. The steep climb shortly after 13:00 is when I DC fast charged.

Still a substantial drawback on a hot day. Once the battery was at 120 F the charge rate was reduced by about half. The exterior temps were around 100-105 F.

Exactly what this particular topic is talking about:

I can attest to that with my 2019 Plus. TMS does matter!

That would have been me with my 62 KWh LEAF, but I'm going to be renting to go to Yuma from Ridgecrest from now on. Last time took me 11 hours on the return trip due to charge throttling.

In 100+ SoCal desert temps, I don't expect any temperature decrease whatsoever.

I wouldn't have even leased this one, had I known about this massive limitation. They gave it a much bigger battery, enough power to merge and pass with no problem, even at SoCal speeds, but hobbled it with no TMS on the battery. Glorified city car still. Not to mention I got a bill for a...

LEAF Spy sure does give you a lot more information than you can get in the car. I'm surprised I didn't try it earlier.

I will try giving the car a break before starting fast charging. With LEAFSpy I can get an idea how quickly the battery can cool when resting.

I'll try a drive and DC fast charge at some point, and check temps with LEAFspy. My experience is a 100 ish mile drive, DC fast charge, and another 100 ish mile drive will find my 62 KWH pack at the very top of normal operating temp range on the temp readout, with the resulting reduction of...

It's possible in the US market they may not implement this fix, for this reason.

I will have to try DCFC again, now that I have LEAFSpy. My experience so far is in ambient temperatures of about 100F. First DCFC is at expected charge rates, but the second after a about 100 mile drive, the temperature display in the car was at the top of the normal operating range, and DCFC...

Done. Granted the petition is for earlier 2018 models, but mine has that issue and it's a 2019 Plus model.

Quick test run with my LEAF Plus: (355.8 V1- 341.6 V2) / 461.8 A at full accelerator = Pack resistance = .0307 Ohm
