Let's see how good the batteries hold up to wind chill of -20.
Wind chill and heat index does not matter for vehicles, the actual temp matters. They arent having to deal with water making a phase change for temperature control, unlike humans.
Unlike gas cars for which one can plug in electric block heaters, batteries all lose charge because of electrochemical sensitivity to cold.
...why the fuck do you think you cant have a battery heater?
And garaging happens because crackheads steal copper, so you keep your home charger in your garage. Not that big of a deal because a garage is cheap to build here.
The lithium chemistry is sensitive to thermal runaway when charging, so the dynamics of a heated system would make charging at cold night somewhat complicate
...a thermostat is a fucking simple invention, it exists in every fridge you own
No, you don't understand thermal runaway. It's complicated. By the time you detect that something is nearing too hot, it can be too late to correct
They don't need to detect nearly too hot, they need to prevent too cold. Prevent the battery from getting below 40 degrees for instance. If battery below 40, heat battery slowly until battery is 40. It isn't trying to keep it at an ideal 80
It isn't a heater to maintain ideal conditions it is a heater to prevent the worst damage. The worst damage is on the opposite end of the spectrum from the issues you are talking about. I am an engineer too, I have just also used a barbecue to make sure a semi starts. You are the embodiment of why I despise all engineers that are under 50. Your over intellectual idiots that do not understand process variation under real world conditions
In wind chill, it can be more complicated than just evaporative cooling of human skin. Other surfaces also can be cooled by wind. ANY wind will carry off higher-energy air molecules from a surface regardless of whether there can be water-based evaporative coolin
No. A car left out in the cold without a heater will be damn near ambient regardless. Wind chill doesnt matter because it wont go below the actual temperature. 0 degrees with -20 wind chill vs 0 degrees with 0 wind chill has damn near zero effect on the car as both cars will be a red cunt hair away from 0.
