GM says wireless battery system speeds EV development, extends range

DETROIT — Normal Motors reported Wednesday its upcoming electric vehicles will use a wireless battery-management process that assists get them to market place a lot quicker and permits a popular set of battery parts to energy a huge vary of EVs.

The battery process, developed with Analog Units Inc., can be current in excess of-the-air to include new technological innovation rapidly, increases vary by decreasing bodyweight and permits employed-up batteries to be converted into clean energy generators, GM reported. It will be standard on all vehicles driven by GM’s proprietary Ultium batteries, like the GMC Hummer pickup coming in 2021 and the Cadillac Lyriq crossover thanks out in 2022.

“Scalability and complexity reduction are a concept with our Ultium batteries — the wireless battery management process is the vital enabler of this awesome versatility,” Kent Helfrich, GM govt director of international electrification and battery programs, reported in a statement. “The wireless process represents the epitome of Ultium’s configurability and ought to aid GM establish lucrative EVs at scale.”

The wireless management process eliminates the require to establish certain conversation programs or redesign wiring configurations for just about every new vehicle, GM reported.

The process can run battery pack health and fitness checks in actual time and aid manage long-phrase battery health and fitness. It cuts down wiring within just the batteries by up to ninety p.c, GM reported, which can prolong charging vary by producing the vehicle lighter and releasing up area for extra batteries.

The wireless process will aid scale Ultium batteries, jointly developed with LG Chem, across GM’s upcoming lineup.

GM has reported it options to start 20 EVs globally by 2023 and much more later on this decade. GM also will use Ultium batteries to codevelop at minimum two Honda EVs and to establish Nikola Corp.’s Badger pickup.

The versatility established by the wireless process will lead to a much more strong manufacturing method and streamlined battery restructuring, GM reported.

The new process also permits GM to much more quickly repurpose the batteries when their capability results in being as well small for optimal vehicle efficiency. At that level, GM reported, the batteries can be employed to build generators by combining various packs without the need of getting to overhaul of the battery management process, as is the situation when repurposing wired batteries.
