Electric vehicles lose up to 50% of their range in cold weather due to heating and limited energy regeneration. A new system could help by using unused energy for heating, reducing the impact of these factors. The study looked at data from BMW i3 and Tesla Model 3 to show that a fast-reacting heater with 20 kW power could make this system work effectively.
