Preheating the battery in the winter confusion and
The battery has an optimum temperature of charge, but the whole point of charging slower away from that optimum is to keep things operating within safe limits. I''m not aware that charging a cold battery super slow is any worse than charging a warm battery super fast. Charging a cold battery super fast is, of course, not good.
Preheating.. is it just BS? | Speak EV
It seems to draw a constant 6.6kW and the overage goes into the battery. It may well all go via the battery. The preheat starts 45-30 minutes before the scheduled time, starting earlier when it''s colder. The energy monitor in the car shows preheating uses up-to 3kW, sometimes less if the target temperature is closer to ambient.

Do you really need to preheat a pizza stone for a whole hour?
77 votes, 43 comments. true. The reason for the long pre heat is the same reason the pizza stone works, it''s got a high specific heat capacity and air doesn''t, air is pretty slow to move heat so it takes a long time for the stone to reach the same temperature as the air because it takes more energy to warm up a pizza stone 1 degree than an equivalent amount of air, same thing when …
