General Motors declares its plans to include heat-pump know-how in all of its current and upcoming Ultium-platform electrical automobiles.
That consists of the Hummer EV now being delivered and the soon-arriving Cadillac Lyriq, plus many extra to arrive within the subsequent several years. In them, the tech will assist recuperate low-level waste heat in methods that can add up in significant ways – bringing them faster acceleration, faster charging, and an extended range
The system relies around an automotive-grade heat pump that captures and recoups that waste warmth. Like ตัววัดแรงดัน like Tesla use or Toyota, the one in GM EVs employs a compressor-and-evaporator element system and a specially chosen refrigerant that undergoes a part change. A bodily reaction pays off in the release of energy as it goes from fuel to liquid—to in impact amplify whatever power it can scavenge alongside the best way.
GM govt vice chairman for Global Product Development, Purchasing, and Supply Chain Doug Parks, says: “Having a ground-up EV structure provides us the liberty to build in normal features like Ultium’s power recovery capabilities. This helps us squeeze extra effectivity, efficiency and total buyer benefit out of our EVs.”
Interestingly, GM notes that the origin of the vitality recovery function may be traced all the way in which back to the company’s EV1, which was its first electric 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 present Ultium EVs, and will also be commonplace in all upcoming Ultium models.
