General Motors will be the first automaker to use an almost completely wireless battery management system, or wBMS, for production electric vehicles.

GM’s wireless battery management system is expected to drive the company’s Ultium-powered EVs to market faster, as time won’t be needed to develop specific communications systems or redesign complex wiring schemes for each new vehicle. The wBMS helps to ensure the scalability of Ultium batteries across GM’s future lineup, encompassing different brands and vehicle segments.
