GM relies on ADI's wireless battery management system
To monitor the batteries of its electric cars, General Motors will use a wireless battery management system its Ultium battery family that has been developed by Analog Devices (ADI).

The wBMS solution not only simplifies manufacturing, but also enables new applications to be built using wireless data," said Patrick Morgan, Vice President, Automotive at Analog Devices. It allows batteries to measure and report their own condition, which allows faster early detection of faults and optimised installation of traction batteries. The data can be remotely monitored throughout the battery life cycle - from assembly, storage and transport to installation, maintenance and any second phase of the battery's life.

Because the wireless management system makes the battery modules smaller and lighter, users such as General Motors in this case can more easily use the modules in their different types of vehicles without having to adapt the wiring harnesses or communication systems.

General Motors introduced its Ultium battery platform in the spring. The Ultium batteries will be produced in partnership with Korean company LG Chem. The Ultium batteries will be used in the full range of GM's planned electric vehicles, including pickup trucks.
