Max charging rate 40 kw

[raijinmach]

I was using a 350 kw level 3 charger and the Mercedes next to me was getting around 70-80 even at 80% but mine only maxed at 40 despite being at 30%. What gives?

How cold was the battery?

How cold was the battery?

It was minus 5 celcius but so was the other car next to me

Is that battery temp, or ambient air?

Not sure. I didn't even know I could check the battery temp. But it was maxed at 40 me from 30-60%

You would need an OBD connection and app such as CarScanner to read the battery temp.
Chances are the Mercedes preconditioned the battery and warmed it up (better than the Mach-E).

Being a California guy, I can’t imagine what that feels like….

Focusing on the other car of a different manufacturer on a different charger doesn’t provide any useful data. Your charging rate could have been rate limited because of something specific about the charger you connected to or your cars cold battery or some other issue. I’m sure you are aware that the Mache max rate is 160 kw for a very short time , plugging into 350 kw charger is.. potentially poor charger etiquette.

No we were both waiting outside for an hour (that's another story) for the chargers to free up

Did you use the built in navigation or android auto to navigate to the charger?

No but like I said, both of us just waited for an hour so even if I did precondition with android auto, it would have dissipated by the time I plugged in

A lot better than -5 Fahrenheit .

Actually, it wouldn't have dissipated.

Actually, it wouldn't have dissipated.

So preconditioning lasts forever?

It can take several hours for the battery to cool down
