...what? You leave your car plugged in, and that's it. Then the BMS will take care of the battery without having to use it's energy.

If I preheat the car it also preheats the battery. If it's not warm enough it won't allow full recuperation. Oh my god, I have to use THE BRAKES for a few minutes, literal trash car.

And all those people in Norway, you know, with their heat pumps and EVs. Obviously life just grinds to a halt there every winter. *dramatic eye roll

Cool. And when you need to drive it? Most systems do not keep the battery heater running indefinitely.

No one is talking about the brakes.

I’m an automotive engineer that has worked for two of the big4. What is your experience?

> And when you need to drive it?

When I need to drive me EV I open the door, get in, close the door, put it in drive and drive off.

Were you expecting something different? I'm in Norway by the way where it is expected to be -15 C in a few days; after eight years of EV driving (2015 Tesla S 70D) I am not anticipating any problems.

I've told you mine, what's yours? Or will you argue from authority again?

driving an ev for the past 2.5 years with 97% SOH remaining. So I must be doing something right wrt treating the battery nicely. And I don't have a garage, it's outside most of the time. I drove thousands of km in subzero C temperature.

>Cool. And when you need to drive it? Most systems do not keep the battery heater running indefinitely.

I get in and put it into drive. When it's cold, I preheat it, I can program departure times, so the battery is conditioned and the cabin warmed in advance. Even at sub-zero temperatures, it always starts reliably, unlike a diesel engine, which, as you know, requires preheating and can struggle with extreme cold starts. Also requires winter diesel.
