TI Reforms EV Battery Management with Wireless BMS Solution

Texas Instruments (TI) has released a major advancement in electric vehicle (EV) battery management systems (BMS) – the industry’s highest-performing solution for wireless BMS, featuring the first independently assessed functional safety concept.

Texas InstrumentsThrough an advanced wireless protocol with the industry’s best network availability, TI’s wireless BMS solution demonstrates how vehicle designers can remove heavy, expensive, maintenance-prone cabling and improve the reliability and efficiency of EVs worldwide.

“The implementation of wireless battery management 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.”

TI’s solution for wireless BMS empowers automakers to reduce the complexity of their designs, improve reliability and reduce vehicle weight to extend driving range. With the flexibility to scale designs across production models, automakers can advance to production faster with TI’s comprehensive wireless BMS offering, including the SimpleLink 2.4-GHz CC2662R-Q1 wireless microcontroller (MCU) evaluation module, software and functional safety enablers such as a functional safety manual; failure mode and effects analysis (FMEA); diagnostic analysis (FMEDA).

To speed automakers’ development time, TI requested that TÜV SÜD, the industry’s leading functional safety authority, independently evaluate the quantitative and qualitative error-detection performance 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, using TI’s wireless BMS functional safety concept.

Using a new wireless protocol, developed specifically for the wireless BMS use case, TI’s wireless BMS functional safety concept addresses communication error detection and security. The proprietary protocol via the CC2662R-Q1 wireless MCU enables a robust and scalable data exchange between a host system processor and the newly announced BQ79616-Q1 battery monitor and balancer.
