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...
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.
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.
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...
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...
