General Motors proclaims its plans to incorporate heat-pump know-how in all of its current and upcoming Ultium-platform electrical autos.
That contains 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 help recover low-level waste heat in methods that can add up in significant methods – bringing them faster acceleration, faster charging, and a longer vary
The system is based round an automotive-grade heat pump that captures and recoups that waste warmth. Like the techniques different automakers 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 phase change. pressure gauge ด้าน ดูด pays off within the release of energy as it goes from fuel to liquid—to in effect amplify no matter power it can scavenge alongside the way in which.
เกจแรงดันน้ำ for Global Product Development, Purchasing, and Supply Chain Doug Parks, says: “Having a ground-up EV architecture offers us the freedom to build in standard features like Ultium’s energy restoration capabilities. This helps us squeeze extra efficiency, performance and overall customer benefit out of our EVs.”
Interestingly, GM notes that the origin of the energy recovery function may be traced all the way again to the company’s EV1, which was its first electrical automotive. The EV1 used a heat pump that was developed by GM engineers at the time. The automaker says the characteristic is on the market on all current Ultium EVs, and also will be commonplace in all upcoming Ultium models.
