General Motors will be the among the first automakers to employ a wireless battery management system, or wBMS, in its production electric vehicles. This wireless system was developed with Analog Devices, Inc., and will allow GM to power many different types of electric vehicles from a common set of battery components.
The new General Motors / Analog Devices wBMS is expected to help get GM’s Ultium-powered EVs to market faster. Rather than 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, from heavy-duty trucks to performance vehicles.
“Scalability and complexity reduction are a theme with our Ultium batteries – the wireless battery management system is the critical enabler of this amazing flexibility,” said Kent Helfrich, GM executive director of Global Electrification and Battery Systems. “The wireless system represents the epitome of Ultium’s configurability and should help GM build profitable EVs at scale.”
