Benefits of the wireless system
With the wBMS, GM can utilize Ultium batteries in each of its electric models, whether they be trucks or SUVs, without needing to redesign wiring schemes or communications systems. As such, GM will be able to more quickly release Ultium-powered EVs on the market.
As technology improves over time, the Ultium batteries can easily be altered to incorporate new features. They could also potentially receive software updates via smartphones, thanks to the new GM Vehicle Intelligence Platform.

The wireless system utilizes up to 90 percent fewer wires to create a cleaner and simpler design. This reduction in wires can lower the weight of vehicles, allow them to have more room for additional batteries, and extend their charging ranges.
Throughout a vehicle’s life, the wBMS will perform battery pack health checks in real-time to ensure everything is functioning properly, and it will help balance chemistry in the battery cell groups to enhance performance. Cybersecurity measures will also protect the wBMS with different features in the software and hardware.
When the batteries no longer work well for the electric vehicles, they can easily be repurposed without requiring a redesign. For instance, battery packs that still function as power supplies can combine together to create clean power generators.
