ADI Launches Industry's First Wireless BMS
Reduced wiring by 90% and battery pack volume by 15%
Applied to EVs equipped with GM's Ultium battery platform


Analog Devices (ADI) announced on the 14th that it is launching a wireless battery management system (wBMS).

ADI's wBMS eliminates harnesses, reducing wiring by up to 90% and shrinking battery pack volume by up to 15%, improving design flexibility and manufacturability without compromising range and accuracy over the battery life.

wBMS is the first wireless battery management system suitable for electric vehicle production, and will be first introduced by General Motors (GM) in a production vehicle based on its Ultium battery platform. ADI and GM recently announced a collaboration to apply wBMS technology to the Ultium battery platform.

It provides all ICs, hardware and software for power, battery management, RF communication and system functions, and supports ASIL-D level safety and module-level security based on proven BMS battery cell measurement technology.

By providing high accuracy over the life of the vehicle, it maximizes the energy utilization per battery cell required by top-tier vehicles and supports safe and sustainable zero-cobalt battery products such as lithium iron phosphate (LFP).

Additional features are also provided to measure and report battery performance, increase early failure detection, and enable optimized battery pack assembly. This enables remote monitoring throughout the entire battery lifecycle, from assembly and storage, through transportation, installation, maintenance, and reuse.
