General Motors just announced a standard feature for its EVs that ride on the company's proprietary Ultium-based architecture. While not specifically called a heat pump in the press release, the special feature – coined "Ultium Energy Recovery" – will capture energy from the battery that may otherwise be wasted. The system then uses it to increase range, charging speed, and acceleration.
GM explains that, as expected, batteries and related parts produce heat. The system can store the excess heat to use when needed. For example, if the stored heat is used to keep the cabin warm, the vehicle will use less energy for its HVAC system, which means more energy for the vehicle itself. The company goes so far as to say that the new Ultium system can even capture outside humidity, as well as the body heat produced by passengers.
