GM’s EV heat pump can extend range up to 10 percent

Keeping an EV's batteries within their optimum operating temperature range is essential to getting the highest performance and longest life cycles possible from them. Too hot and charge seeps from the cells, too cold and the vehicle's range can drop up to 20 percent with charging sessions taking significantly longer than they would in warmer climes. This is why heat pumps, devices that scavenge waste heat from a vehicle's engine components to provide power other systems, have been finding their ways into a number of electric autos in recent years. Tesla has added them to its Model Y, 3, and S Plaid; Polestar includes them with the PS2 single-motor, and Rivian, well, Rivian does it a little different, but on Monday, GM announced its latest entry into waste heat reclamation game with the debut of its "Ultium Energy Recovery" system.
