GM likes to give us a tidbit about its Ultium platform from time to time and today it is telling us about the platform’s ability to capture waste heat from propulsion systems. In addition to capturing from the propulsion system, it can capture moisture from both inside and outside the vehicle and Even From the body heat of the passengers. Yes, you, your family and / or your friends are a source of heat for GM EVs. It then sets the heat in a convenient way. If at this point, you’re shouting, “Heat pump!” You will be fine. We are talking about a comprehensive heat pump system that GM is using for its Ultium-based vehicles.
Each Ultima-based GM car receives this system, which is covered by 11 patents and four publications. The waste heat it collects is used in a variety of ways, but its primary use is to heat the cabin quickly and efficiently. GM claims that it can heat the cabin of its ultium-based vehicles faster than vehicles with conventional internal combustion engines. Also, when used, GM claims that its EVs offer up to 10% more range than when they use a heat pump.
Outside of heating the cabin, the heat pump is able to preheat the battery before charging and keep the waste heat for use so you can charge faster. The system can even cool the propulsion system to prepare for the launch of Watts to Freedom (WTF) launch control. GM said it was important to help Hummer EVs reach 0-60 mph in about 3 seconds.
“Having a ground-up EV architecture gives us the freedom to create standard features like Ultium’s energy recovery capabilities,” said Doug Parks, GM executive VP of global product development, purchasing and supply chains. “It helps us get more efficiency, performance and overall customer benefits from EVR.”
GM says it is developing heat pump technology from the EV1 and its heat pumps. This is the modern evolution of that technology, and GM says it will be applied as an ideal feature in every ultium-based vehicle.
