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 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. Instead, the wBMS helps to ensure the scalability of Ultium batteries across GM’s future lineup, encompassing different brands and vehicle segments, from heavy-duty trucks to performance vehicles. Much like the pack design of GM’s Ultium batteries, which is flexible enough to incorporate new chemistry over time as technology changes, the wBMS’ basic structure can easily receive new features as software becomes available.
