General Motors declares its plans to include heat-pump know-how in all of its present and upcoming Ultium-platform electrical automobiles.
That includes the Hummer EV now being delivered and the soon-arriving Cadillac Lyriq, plus many extra to arrive in the next several years. In them, the tech will assist get well low-level waste heat in methods that may add up in meaningful methods – bringing them faster acceleration, faster charging, and a longer range
The system is based round an automotive-grade heat pump that captures and recoups that waste heat. Like digital pressure gauge like Tesla use or Toyota, the one in GM EVs employs a compressor-and-evaporator component system and a specifically chosen refrigerant that undergoes a phase change. A bodily response pays off within the release of power as it goes from fuel to liquid—to in effect amplify whatever power it could scavenge along the way.
GM executive vp for Global Product Development, Purchasing, and Supply Chain Doug Parks, says: “Having a ground-up EV structure offers us the freedom to construct in standard features like Ultium’s vitality recovery capabilities. This helps us squeeze more efficiency, performance and overall buyer benefit out of our EVs.”
Interestingly, GM notes that the origin of the energy recovery characteristic can be traced all the way again to the company’s EV1, which was its first electrical car. The EV1 used a heat pump that was developed by GM engineers at the time. The automaker says the characteristic is out there on all current Ultium EVs, and will also be normal in all upcoming Ultium models.
