announced that its wireless battery management system (wBMS) is certified to the highest standard of automotive cybersecurity engineering and management. ISO/SAE 21434 is the new standard for managing cybersecurity risks throughout the vehicle lifecycle – from product design, development and production, to the operation, maintenance and decommissioning of electrical and electronic systems.
TÜV NORD Mobilität, the evaluator of this qualification, stated that ADI's wBMS is the first automotive system certified to ISO/SAE 21434. The evaluation confirmed that ADI carried out appropriate assurance measures in the development of the product to meet the requirements of CAL 4.
Since announcing the industry's first wBMS with General Motors in 2020, ADI has brought this technology to mass production as a turnkey solution for vehicle manufacturers with safety engineered at every level.
Transitioning batteries from wired to wireless connectivity enables automotive manufacturers to scale their electric vehicle fleets for volume production across a wide range of vehicle classes, and wBMS provides modularity, flexibility and scalability to streamline battery production processes. design and assembly with connectors - free batteries.
With this dependence on wireless communication, it is essential to ensure the transparency, security and ease of deployment of the system.
“We performed an intensive assessment to verify that ADI's wBMS complies with the requirements of ISO/SAE 21434. With ADI considering CAL 4 classification conditions throughout product development, cybersecurity assurance measures met the highest requirements,” said Leif-Erik Schulte, Senior Vice President of TÜV NORD Mobilität. “This system certification is a key element in building trust across the entire electrification ecosystem – from energy storage to OEMs and consumers – to support EV adoption and help reduce emissions.”
According to a recent McKinsey report: “Cybersecurity is becoming a new dimension of quality for automobiles… cybersecurity will be non-negotiable to ensure market access and type-approval” in the future.
The CAL 4 classification, in accordance with ISO/SAE 21434, requires robust risk assessments to proactively identify any component, application programming interface (API), or software function that may be vulnerable to a cyberattack.
“Personal vehicles are a leading contributor to global warming and the accelerated adoption of electric vehicles plays a critical role in achieving a sustainable future,” said Roger Keen, general manager of battery management systems at Analog Devices. “Improving the safety and accuracy of electric vehicle batteries eliminates obstacles in end-user purchasing considerations and advances OEMs’ decisions to expand their electric vehicle offerings. With this certification, ADI can provide continued transparency and seamless implementation across the EV battery supply chain to advance our vision of a greener world.”
