No heat issues charging my 2019 Leaf Plus 62 kwh
You state that your battery temp stayed the about same. Your battery temp went from about 85F to over 100F,
as indicated by the bar graph, check your video. That's what usually occurs when using L3 versus L1/L2.
Not sure what you are trying to nit pick...but I clearly showed it increased in the video...and remained at the level even after driving it back home.

Once again my comment was "no heat issues charging my......" I never said it didn't increase....I see no issues with that temp level.
Consider reading the numerous threads on MNL about how temperature, the result of heat, affects battery degradation
whether it's ambient or internally developed. Remember, Leafs lack a battery TMS like other BEVs, e.g. GM Bolt or Tesla M3.

That's ok...I rather enjoy the car than worry too much :D ....plus... I doubt I will do more than a few quick charges per year...if any...due to my planned use of this car.

Thanks Learjet. For some reason, few of the car reviews/magazines show off the faster charging rate. Given the large number of Leafs going into Norway each month, I am surprised that there are not faster Chademos being installed.

Yes one charge at L3 is fine. The issue is the 2nd, 3rd+ L3 charge during the same day on an extended drive.
Always been fine at just one.
1 bar lost at 21,451 miles, 16 months.
2 bar lost at 35,339 miles, 25 months.

Temperature increase was moderate so no problem. Charge rate was similar to my last QC, but tapered a little sooner (probably due to higher ambient temperature for your charge session).

The faster charge rate is one of THE biggest reasons I wanted the E Plus.

Contrast; yesterday at EVgo,
max rate 120 amps
Ending rate 120 amps
Charge 18-65%
27.65 kwh
time 35:58
Ending batt temps; 75-79º

Cost under COVID discount would have been $7.00 but free to me

Consider your usage and your climate.

Unless you plan on many DCQCs in a hot climate, or live in a very hot climate, a TMS doesn't have a strong impact on battery life. Long trips at high speed involving many DCQC sessions per day will have much slower charge rates.

Also consider the advantages of not having a TMS. The car is simpler, more reliable and far less likely to catch fire.

Start at 2:23 of your video. You said, "battery temperature is hanging in there, hasn't creeped up any higher."

It did increased one bar from when you started charging and that's why lorenfb stated that. Sorry for nit picking. :D

Does or doesn't e-Golf have a similar problem?

Fri May 29, 2020 2:25 am

Hi guys,

since the prices for used electric cars go down nicely, I am deciding between Nissan Leaf 2019 and e-Golf 2019.

I did read about Rapidgate but isn't it the same problem with Golf since the battery is not actively cooled either?

I'd love to buy this one https://elektromobilne.cz/nissan-leaf-j ... ktromobil/ because of the 7,9 secs acceleration but wouldn't it be more reasonable to go for more reliable rapid charging in case the e-Golf doesn't have these problems?

Does it? There is no mention on the internet about similar problem with Golf, could it be the engine sucks just 100 kW and the acceleration is slower by almost two seconds - and / or better charging management?

Thanks for any hints on that matter. I'd love to buy Leaf but also I have to be able to travel and charge in reasonable time.
