Rohde & Schwarz leverages technology from Analog Devices to develop a wireless battery management system production test solution

01/22/2024

The battery management system (BMS) is one of the most vital components of an electric vehicle (EV), ensuring safe and efficient management of the battery pack and thereby influencing the safety, range and performance of EVs. Traditional BMSs are wired systems which limit the design flexibility and EV production scalability, as well as increase the weight of the vehicle. A more advanced approach is to perform the communication between the Cell Monitoring Controller (CMC) for each battery module and Battery Management Controller (BMC) wirelessly. This simplifies the assembly, maintenance, and exchange of cells resulting in cost and effort advantages. In addition, it saves space and provides weight reduction in the vehicle.

ADI, a global semiconductor leader and pioneer for battery management technology, has developed a complete wBMS. ADI’s wBMS, currently in production across multiple EV platforms, is the first ISO21434 CAL4 compliant wBMS which adheres to the strictest cybersecurity standards. It also meets high requirements in RF performance and robustness to maximize battery capacity and lifetime value.
