Energy storage systems
Design reliable and efficient energy storage systems with our battery management, sensing and power conversion technologies
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
EIS is a non-destructive test that measures a battery's internal resistance across different frequencies. It injects a tiny alternating current (AC) signal into the cell to track how internal chemical and physical processes respond.
Unlike standard monitoring ICs that only measure total voltage or overall resistance, EIS isolates individual internal factors. It maps out specific health indicators, such as anode/cathode degradation, lithium diffusion speeds, and Solid Electrolyte Interphase (SEI) layer growth. This provides a highly detailed diagnostic readout of a battery's true state of health.

Increase safety at low and high voltages
Active cell balancing is an advanced battery management technique that redistributes charge among cells in a pack during charging and discharging. Unlike passive balancing, which wastes excess energy from higher-charged cells as heat through resistors, active balancing uses energy-storage elements to shift energy directly from stronger cells to weaker ones.
This process minimizes energy waste, reduces heat generation, maximizes the usable capacity of the battery pack, and extends overall battery life.
