#1 Today’s eMobility’s Best of 2021: Wireless battery management systems

As electric vehicle (EV)production volumes increase, automakers look to simplify battery engineering, assembly, scalability, and maintenance.

General Motors’ Ultium battery packs will use a wireless battery management system (wBMS) developed by Analog Devices to track and manage conditions in future electric vehicles (EVs).

Customized parts unique to a single vehicle work fine when volumes are low. General Motors (GM) can afford to use unusual parts on the Chevrolet Corvette (21,626 sales in 2020) that would become prohibitively expensive on the Silverado pickup line (594,094 sales).

As electric vehicles (EVs) move from Corvette-like niche numbers into high-volume, automakers must standardize as much as possible to simplify engineering, design, and manufacturing. Early simplification candidates are battery pack wiring harnesses.
