Why choose TI for your battery management system?
Maximize driving range
Enchance state-of-charge accuracy with high-precision battery monitoring and reduce vehicle weight with advanced wireless battery management system.
Enable safer operation
Advanced diagnostics and early detection help to prevent thermal runaway and propagation.
Make electric vehicles (EVs) more affordable
Our technology enables the use of multiple battery chemistries (including lithium iron phosphate (LFP)) and move to new advanced architectures.
Enabling technologies
Accurate monitoring
Battery monitoring integrated circuits (ICs) measure cell voltages and temperature and perform cell balancing to monitor and protect the cells. Accurate monitoring enables more efficient battery use, resulting in longer run time and a reduction in battery size and cost.
The pack monitor performs high voltage, current and temperature measurements to diagnose and manage the safety of the battery packs. Our battery cell monitoring ICs and pack monitors are designed to work together, to enable synchronized measurements of cell voltage, pack voltage and current.

Delivering industry-leading reliability
Our portfolio of solid-state relays deliver industry-leading reliability to help make electric vehicles safer.
Benefits:
- Increase reliability with 10 times higher operating lifetime than electromechanical relays.
- Reduce system size and cost by up to 50% with integrated power and signal isolation.
- Improve safety of 800-V EV battery-management systems: solid-state relays survive more avalanche current than traditional photorelays, eliminating the need for a reed relay disconnect.
