GM’s Ultium Energy Recovery System Helps EVs Conserve Battery Power

General Motors has announced plans to equip its Ultium-based electric vehicles with new heat pump technology that can increase range, performance and charging speeds.

General Motors announced plans to equip its Ultium-based electric vehicles with new heat pump technology that can increase range, performance and charging speeds. However, for all its environmental benefits, the one area where electric vehicles fall short is their stability and efficiency in cold weather. While manufacturers typically rely on heaters to draw power from the battery to heat the cabin, some modern electric vehicles now use heat pumps for this purpose.

Unlike resistance heaters, heat pumps generate no heat. Instead, they transfer heat from the source to the target area using refrigerants as the transfer medium, much like air conditioners. The technology can be used to improve a vehicle’s power and range compared to cars with similarly sized batteries. Tesla already uses the technology on several of its vehicles, including its Model Y, Model 3 and Model S Plaid, while Polestar uses it on the Polestar 2.

In its Monday press release, GM said all of its Ultium-based electric vehicles will come with its newly patented heat pump that will harvest redundant energy from the battery. “to power heating and propulsion while helping to maintain range.” According to GM, Ultium’s energy harvesting capabilities not only increase range by up to 10 percent, but it also contributes to more efficient charging by warming up the batteries before charging them. The Ultium platform also helps recover wasted thermal energy from a vehicle’s batteries, electronics and other propulsion components to heat the cabin faster in cold weather than typical heaters used in internal combustion engine cars.

As an example of the Ultium platform’s energy recovery system used in a production vehicle, GM said the Hummer EV’s “Watts to Freedom” feature helps pre-cool its propulsion system for it. accelerate from 0 to 60 mph in just about three seconds. . Elaborating on the new feature, GM executive vice president Doug Parks said it was made possible by the company’s decision to have a core EV architecture.

GM has already announced a ton of new electric vehicles that are already on the market or will be available for purchase in the next two years. This includes the Hummer EV, which was announced in 2020 and was sold through 2024. Some of GM’s other electric vehicles include the Lyric, the upcoming Blazer EV, and the Chevy Silverado which was announced a few months ago. General MotorsThe press release suggests that all of these vehicles will feature the new power-saving technology, which would be good news for buyers in terms of range, performance and charging speeds.
