It could be as simple as the equivalent of a “block heater” that you would use on a ICE in a cold climate. These are not new technologies, many use these simple devices for cars in places where it gets cold, and I can’t imagine installing a correctly engineered device into the battery coolant system would pose much of a problem. Automatically turn on at a predetermined departure time or below a certain temperature while charging.
That doesn’t help much with the reduced range thanks to the cold, but it will get you going in the morning. We have a PHEV that won’t let you use the battery below 20°F, but the ICE warms the battery and it comes online about 5 minutes after start.
Yeah, most of what I’ve seen is just heating the battery. Which is also dramatically reducing the efficiency.
There’s no way around sacrificing range to heat the battery at this time. Only mitigating some of the loss with a preheat.
That’s what I thought. Not an issue with hydrogen.
If we’re going to be discussing battery vs hydrogen efficiency, we need to be honest about how it performs in real-life scenarios like this. Only discussing EV performance in ideal conditions is providing nowhere near the full picture.
I’m not trying to start any argument about either of them, I’m for getting off of fossil fuels, and more choices to better fit different needs is great. Hydrogen cars have their own issues, such as lower energy density and very high pressures for storing the hydrogen, along with high pressure vessels for transporting it. Energy dense storage is always going to have problems, but the electricity distribution system is already well established.
