Build a more sustainable future by designing safer, more accurate energy storage systems that store renewable energy to reduce cost and optimize use. With advanced battery-management, isolation, current-sensing and high-voltage power-conversion technologies, we support designs ranging from residential, commercial and industrial systems to grid-scale systems with voltages as high as 1,500V.
Why choose TI for your energy storage system designs?
Scalable designs
Our stackable battery-management architecture supports residential, commercial, industrial and grid-scale systems as high as 1,500V at an optimized system cost.
Efficient power conversion
Our GaN FETs, gate drivers and real-time microcontrollers increase efficiency and power density by reducing switching and conduction losses and enabling higher switching frequencies.
Safe, reliable systems
High-accuracy battery monitoring, current sensing and isolation, and integrated diagnostics all contribute to increased system reliability.
Engineering efficient energy storage systems
Accurate monitoring
Battery monitoring integrated circuits (ICs) measure cell voltages, temperature and pack current; perform cell balancing; and monitor and protect cells. Accurate monitoring enables more efficient battery use, resulting in longer run times and a reduction in battery size and cost. Our pack monitors accurately measure voltage and temperature to diagnose and manage the safety of battery packs.
Our battery cell monitoring ICs work well in Controller Area Network (CAN) or daisy chain-based architectures to meet your requirements.
