Texas Instruments (NASDAQ:TXN) Introduces Advanced EV Battery Management System with functional Safety Concept
Texas Instruments (NASDAQ:TXN) is revolutionizing electric vehicle battery management systems following the launch of an advanced EV BMS featuring an independently assessed functional safety concept. TI’s wireless BMS solution employs advanced wireless protocol with enhanced network ability. It shows a way of removing expensive, heavy, and maintenance-prone cabling in BMS to enhance the efficiency and reliability of electric cars globally.
TI’s Wireless BMS solution reduces design complexity
Most importantly, TI’s wireless BMS solution helps automakers in reducing complexity in design, minimize vehicle weight, and improve reliability to boost driving range. With enhanced flexibility, they can scale designs across different production models to quickly produce with the extraordinary wireless BMS solution. The offering includes the SimpleLink™ 2.4 GHz CC26662R-Q1 wireless microcontroller evaluation module, software, and safety enablers. The safety enablers comprise of safety manual, diagnostic analysis (FMEDA), Failure Mode, and effect analysis (FMEA), and many more.
Strategy Analytics’ powertrain, chassis, body and safety service director, Asif Anwar said that the implementation of wireless BMS is a growing trend in the electric car marketplace. Anwar says that the reason behind the advancements is because they offer enhanced design flexibility while at the same time lowering cost and complexity compared to conventional systems. Further, he indicated that the TI solution has set a benchmark for the industry.
TI wants TUV SUD to evaluate the wireless BMS safety concept
To accelerate development time for automakers, TI has asked the industry’s functional safety authority, TUV SUD to independently assess the qualitative and quantitative error detection performance and feasibility of automakers achieving ASIL D with the wireless BMS safety concept. Through the new wireless protocol, designed specifically for wireless BMS, TI’s wireless BMS safety concept tends to address communication error recognition and security. Most importantly the proprietary protocol through CC2662R-Q1 wireless MCU enhances scalable and robust data exchange between the BQ79616 battery monitor and balancer and the host system processor.
The TI BMS wireless protocol rivals wired connection through the CC2662R-Q1 wireless MCU which offers enhance network availability of more than 99.999% with network restart of around 300-ms.
