General Motors will be the first automaker to use an almost completely wireless battery management system, or wBMS, for production electric vehicles. The wireless battery monitoring system will be standard on all planned GM vehicles powered by Ultium batteries.
- Up to 90% weight reduction = greater range
- The space and flexibility created by this reduction in wires not only enables a cleaner design, but also simpler and more streamlined battery restructuring as needed
- Time won’t be needed to develop specific communications systems or redesign complex wiring schemes for each new vehicle = enabling scalability of Ultium batteries across GM’s future lineup including trucks and performance vehicles
- The wBMS’ basic structure can easily receive new features as software becomes available. With expanded over-the-air updates provided by GM’s all-new Vehicle Intelligence Platform, the system could even be upgraded over time with new software-based features via smartphone-like updates.
- Protected by cybersecurity measures that are foundational to the company’s all-new electrical architecture or Vehicle Intelligence Platform. The DNA of this syst
General Motors’ Future Electric Vehicles to Debut Industry’s First Wireless Battery Management System
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...
