Analog Devices has launched wireless battery management system (wBMS) which will debut on General Motors’ production vehicles powered by Ultium batteries. The company claims, this is the first wireless battery management system available for production electric vehicles.
According to the company, some features of wBMS are as follows:
It allows automotive manufacturers increased flexibility to scale their electric vehicle fleets into volume production across a wide range of vehicle classes. It eliminates the traditional wired harness, saving up to 90% of the wiring and up to 15% of the volume in the battery pack, as well as improving design flexibility and manufacturability, without compromising range and accuracy over the life of the battery.
It includes all integrated circuits, hardware and software for power, battery management, RF communication, and system functions in a single system-level product that supports ASIL-D safety and module-level security.
By delivering high accuracy for the lifetime of the vehicle, the system enables maximum energy use per cell required for best vehicle range and supports safe and sustainable zero-cobalt battery chemistries, such as lithium iron phosphate (LFP).
ADI and General Motors recently announced a collaboration, bringing the wBMS technology to General Motors’ Ultium battery platform. The ADI technology helps ensure scalability of the Ultium platform across General Motor’s future lineup, which will encompass different brands and vehicle segments, from work trucks to performance vehicles.
