Wireless battery management for electric vehicles (EV) is now a reality, finally reaping the long-promised advantages of wiring harness elimination and pack simplification. These in turn reduce the vehicle weight that help extend driving range and enable automation in manufacturing that increase mechanical reliability of the pack.Going wireless is not without challenges. Technological innovations are needed to achieve wireless robustness to interference and to ensure safety. Yet the system would not be complete if system security was not considered from the beginning. After all, the threat of the wireless interface being exploited by a remote malicious attacker to gain control of a mission critical application within a vehicle is a scary proposition
