General Motors will be the first automaker to use an almost completely wireless battery management system, or wBMS, for production electric vehicles. This wireless system, developed with Analog Devices, Inc., will be a primary driver of GM’s ability to ultimately power many different types of electric vehicles from a common set of battery components.
The wBMS is expected to drive GM’s Ultrium-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.
