Analog Devices' wireless battery management system (wBMS) has achieved the highest level of automotive cybersecurity certification, meeting the industry's demand for reliability.


Analog Devices announced today that its wireless battery management system (wBMS) has achieved the highest level of automotive cybersecurity engineering and management qualification certification.

ISO/SAE 21434 is a new standard for cybersecurity risk management across the entire vehicle product life cycle, from electrical and electronic system conception, product development and manufacturing, to operation, maintenance, and decommissioning.

TÜV NORD Mobilitat, the assessment body for this certification, confirmed that ADI's wBMS is the first automotive system to receive ISO/SAE 21434 certification.

This assessment certifies that ADI has taken appropriate assurance measures during product development to meet CAL 4 requirements.

Since announcing the industry's first wBMS with General Motors (GM) in 2020, ADI has been delivering this technology to high-volume production as a turnkey automotive solution designed to support security at every level.

The shift from wired to wireless battery pack connectivity enables automakers to mass-produce a wide range of electric vehicle (EV) products across a wide range of vehicle classes, and wBMS provides modularity, flexibility, and scalability that streamlines the design and assembly process by utilizing connector-free batteries.

As our reliance on wireless communications networks grows, ensuring clarity, security, and ease of application becomes increasingly important.

“We conducted a rigorous assessment to ensure that ADI’s wBMS complies with ISO/SAE 21434 requirements. The cybersecurity assurance measures ADI took into account throughout the product development process, taking into account CAL Level 4 conditions, complies with the highest requirements,” said Leif-Erik Schulte, Senior Vice President at TÜV NORD Mobilitat. “The certification of this system is a key element in supporting EV adoption and contributing to reducing carbon emissions by building trust across the entire electrification ecosystem, from energy storage to OEMs and consumers.”

According to a recent report by McKinsey,1 "cybersecurity is becoming the new standard for automotive quality. Going forward, cybersecurity will be a non-negotiable requirement for market access and type approval."

A CAL 4 rating according to ISO/SAE 21434 requires a robust risk assessment to proactively identify components, application programming interfaces (APIs), or software functions that may be vulnerable to cyberattacks.

“With personal vehicles a major contributor to global warming, accelerating EV adoption is critical to achieving a sustainable future,” said Roger Keen, general manager of Battery Management Systems at Analog Devices. “Enhancing the security and precision of EV batteries can remove barriers to end-user purchasing decisions and also facilitate OEMs’ decisions to expand their EV product lines. "This certification furthers ADI's vision of creating a greener world by providing consistent, transparent reliability and seamless installation across the EV battery supply chain. Furthermore, it will save customers time on cybersecurity development and related infrastructure investments, enabling OEMs to accelerate time to market," he added.
