TI rolls ecosystem around battery management, traction inverters
With a range of reference designs and related analog circuitry, Texas Instruments is contributing to reducing CO2 emissions from traffic. These new products help automotive designers to increase system reliability in hybrid and electric vehicles.

Scalable across six to 96-series cell supervision circuits, TI’s new battery management system (BMS) reference design features the advanced BQ79606A-Q1 precision battery monitor and balancer. Engineers can get their automotive designs to market quickly using the reference design, which implements the battery monitor in a daisy chain configuration to create a highly accurate and reliable system design for three- to 378-series, 12-V up to 1.5 kV lithium-ion battery packs.

The highly integrated BQ79606A-Q1 monitors temperature and voltage levels and helps maximize battery life and time on the road. Additionally, the BQ79606A-Q1 battery monitor features safe-state communication that helps system designers meet requirements up to Automotive Safety Integrity Level D (ASIL D), which is the highest functional safety goal defined by the ISO 26262 road vehicles standard.

With so many kilowatts of power filtering through an electric vehicle’s traction inverter and batteries, high temperatures could potentially damage expensive and sensitive powertrain elements. Excellent thermal management of the system is crucial to vehicle performance, as well as protecting drivers and passengers.
