Re: 2019 Leaf battery overheating

Sun Jan 05, 2020 3:56 am

For the folks here complaining about Leaf DC FCing slowing down as the battery got too hot and me bringing up thermal management on Bolt, I just learned the guy I posted at viewtopic.php?p=575995#p575995 did the "Cannonball Run" in a Bolt across the US in about 79 hours. He most definitely did multiple DC FCs in a day.

'19 Bolt Premier
'13 Leaf SV w/premium package (owned)
'13 Leaf SV w/QC + LED & premium packages (lease over, car returned)

Please don't PM me with Leaf questions. Just post in the topic that seems most appropriate.

Yup. Until Nissan adds active thermal management to the battery all need to know one L3 charge per day is a practical maximum.

Perfect for travelling about 1.5 to 2x the actual range per day. Very limited beyond that. That's just the way it is by design. Nothing is wrong with the vehicle.

I tend to agree. Our longest day on our regular road trip is exactly 554 km. Should be a good fit for the Eplus. Not so much for our 2016 SV but we do it. The chihuahua and I need to pee often anyway. 😜

I have found that multiple L3 charges in one day only adds about 15-20 minutes to the total time for all three charge sessions compared to doing just one session per day.

I did that distance and stopped to charge several times for 20 - 25 minutes. The E Plus "seems" to shed heat better but will need to do some Summer driving to know for sure. I will say the BMS is completely different than my 40 kwh LEAF. Nearly everything is different in how the car charges during various conditions.

Typical day for us when we used the grand Cherokee was a 15 to 20 minute morning coffee, walk and pee brake, a half hour lunch and a 15 minute afternoon break. There is lots of charging opportunities along the way. We’ll charge during all our breaks. We tend to set the cruise at about 105 kmh.

Re: 2019 Leaf battery overheating

OK, so I figured I should let you guys know what i've been doing in the meantime.
Sorry for being offline for so long. Life...

In short, we leased a Model 3. Dual Motor, Long Range (75kWh)
I still have my leaf (2y lease ends May 2021) but we sold our Prius and now we are 100% gas-free.

The Tesla came on Dec 19. This goes off-topic but I love it.

So the formula is simple. Leaf cannot be counted on for longer trips due to the lack of thermal management. But it's a pleasant vehicle to drive for decent distances around the residence. I know that if I have to DC charge I am opening myself to frustration as I never know how long it will take me. So i plan to not have to.

Tesla on the other hand has no problem whatsoever with long hauls. I had to pick-up my girls from EWR and JFK before Christmas and all went super smooth. The trip to EWR and back, i did without Supercharging. Going to JFK, I had to Supercharge while waiting for her to clear customs. Charging at 90 kW is a breeze. It can do 150 kW but I never experienced that. Whatever...

At home I use the same Siemens wall unit I used since my first Leaf. It delivers 30 A which is not the max Tesla can take (48A) but i find it sufficient. Not having to table 500$+ install for the Tesla wall unit makes me happy. FYI the model 3 comes with a little adapter to a SAE J1772 plug so i was ready to charge from the moment we brought it home.

Besides that, you have no idea how 170W/kg feels in comparison to only 70W/kg for the Leaf. Woosh!

Open for questions if anyone has any...
