WIRELESS BATTERY MANAGEMENT SYSTEM Analog Devices’ wireless battery management system achieves top automotive cybersecurity qualification

Apr 25, 2022

Analog Devices, Inc announces achievement of certification of its Wireless Battery Management System (wBMS) to ISO/SAE 21434, which is the highest standard of automotive cybersecurity engineering and management. ISO/SAE 21434 is the new standard for cybersecurity risk management throughout the lifecycle of the vehicle from concept, product development and production, to operation, maintenance, and decommissioning of electrical and electronic systems.

Analog Devices, Inc recently announced its Wireless Battery Management System (wBMS) is certified with ISO/SAE 21434. TÜV NORD Mobilität affirmed that ADI’s wBMS is the first automotive system that it has certified for ISO/SAE 21434. The assessment confirmed that ADI performed appropriate assurance measures within the product development to fulfil the CAL 4 requirements.

Talking about the findings, Leif-Erik Schulte, Senior Vice President, TÜV NORD Mobilität, cited, “We conducted an intensive assessment to verify that ADI’s wBMS conforms to ISO/SAE 21434 requirements. With ADI considering the CAL 4 classification conditions throughout product development, the cybersecurity assurance measures complied with the highest requirements. This system certification is a key element to build trust across the full electrification ecosystem – from energy storage to OEMs to consumers – to support EV adoption and help reduce emissions.”

According to a recent McKinsey report1, ‘Cybersecurity is becoming a new dimension of quality for automobiles. Cybersecurity will be non-negotiable for securing market access and type approval’ in the future. The CAL 4 classification according to the ISO/SAE 21434 standard requires strong risk assessments to proactively identify any component, application programming interface (API) or software function that could be vulnerable to a cyber-attack.

Further, Roger Keen, General Manager of Battery Management Systems, Analog Devices, said, “Personal vehicles are a major contributor to global warming and accelerated EV adoption plays a critical role in achieving a sustainable future. Improving the security and accuracy of EV batteries removes roadblocks in end-users’ buying considerations and advances OEMs’ decisions to expand their EV offerings. With this certification, ADI can provide ongoing transparency and seamless deployment within the EV battery supply chain to progress our vision of a greener world. It further accelerates the speed to market for our customers by saving their cybersecurity development time and associated infrastructure investment.”
