Analog Devices, Inc. announced its expanded portfolio of battery management system (BMS) products including ASIL-D functional safety and innovative new low-power features to enable continuous battery monitoring. These new devices further differentiate ADI’s BMS platform that today delivers the industry’s best proven accuracy, and supports all key battery chemistries—including zero-Cobalt LFP (lithium iron phosphate)—for mass market electric vehicles (EVs) and energy storage systems (ESS) used for reuse and recycling of battery packs.

ADI’s BMS products are optimized for 6-18 cell modules and offer a range of features including low-power continuous battery monitoring, state-of-the-art functional safety, and the world’s best accuracy guaranteed across the entire vehicle lifetime and device temperature range.

Sales of full EVs continue to accelerate as consumers increasingly move to greener transportation and governments act to create a more sustainable future. Automakers are challenged to scale their EV fleets economically, while also staying ahead of evolving safety requirements across the world. Furthermore, to ensure maximum range per charge, the vehicle power consumption must be managed not only during driving, but also when the vehicle is parked. ADI’s newest BMS products support multiple battery cell configurations and deliver innovative low-power features that enable the battery to be monitored continuously even when the vehicle is turned off to ensure safety under all conditions while maximizing vehicle range.

As EVs become mainstream in the market, requirements for BMS are growing. Receiving the ASIL-D rating signifies the new BMS solutions meet the highest possible standards for road vehicle functional safety required by regulatory agencies across the world.
