Is there a proven way to heat the battery prior to charging? Thinking of several or many max accelerations in the minutes prior to charging? Trying to find ways (proven) to increase the charge rate on cooler/cold days. I am over 90 miles away from the nearest >150kW charger so can't try it myself. I'm looking to travel from the south to Maryland late next week. Please, No Guesses, just tried and true techniques you have used. We RWD drivers need real answers because we will never have a battery heater.
