Wireless BMS meets ASIL D
Texas Instruments has launched a wireless battery management system (BMS) for electric vehicles. With the move, TI throws down the gauntlet to the previous market leader ADI: TI's BMS is supposed to scale better - and it is independently certified to ASIL4, the highest level in the ISO 26262 functional safety scoring system.

On behalf of TI, TÜV SÜD as functional safety certifcation agency has evaluated the quantitative and qualitative error-detection performance of this wireless BMS functional safety concept, as well as the feasibility for automakers to achieve Automotive Safety Integrity Level (ASIL) D, the highest level of International Organization for Standardization (ISO) 26262 certification.

Neutral observers are also convinced of the advantages of wireless BMSs. “The implementation of such systems will be a growing trend in the EV marketplace because these advancements provide greater flexibility of design while also lowering the complexity and cost relative to traditional systems,” said Asif Anwar, director of the powertrain, body, chassis and safety service at Strategy Analytics. “By demonstrating a solution that combines these advantages with ASIL D compliance, the TI solution sets a benchmark for the industry to follow.”
