General Motors has announced it will be the first automaker to use an almost completely wireless battery management system (wBMS) for production of electric vehicles. The wire-free system is expected to drive GM’s Ultium-powered EVs to market faster. The wBMS will help ensure the scalability of Ultium batteries across GM’s future lineup. “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,” he added.
