GM’s Ultium EV “heat pump” improves vary, charging and acceleration

General Motors declares its plans to include heat-pump know-how in all of its present and upcoming Ultium-platform electrical automobiles.
That contains the Hummer EV now being delivered and the soon-arriving Cadillac Lyriq, plus many extra to arrive within the next a number of years.

The EV1 used a warmth pump that was developed by GM engineers on the time. The automaker says the function is available on all current Ultium EVs, and also will be commonplace in all upcoming Ultium fashions.
