Energy storage has been an integral component of electricity generation, transmission, distribution as well as consumption for well over many decades. Today, the power landscape is changing dramatically with the growing renewable energy generation. This shift to renewable sources also makes delivering power reliably, where and when it’s needed, a bigger challenge than ever before.
Energy storage systems provide a wide array of technological approaches to manage our supply-demand situation and to create a more resilient energy infrastructure and bring cost savings to utilities and consumers.

Infineon’s unique expertise in energy generation, transmission, power conversion, and battery management makes us the natural partner to advance Energy Storage Solutions (ESS) in terms of efficiency, innovation, performance, and optimal cost. Our discrete OptiMOS™, CoolMOS™, and CoolSiC™ MOSFETs and IGBTs modules, as well as highly integrated 3-level Easy 1B/2B modules, functionally integrated EiceDRIVER™ gate driver ICs,  XMC™ controllers and security solutions are ideal in a wide range of energy storage system designs.

Battery-based ESS technology can respond to power drop-outs in under a second, making use of clean energy sourced from collocated solar or wind plants. In such before-the-meter cases, ESS functions as bulk storage coupled with either renewables generation or transmission and distribution systems. In residential and commercial situations, ESS plays a role as behind-the-meter.

Energy Storage Systems are structured in two main parts. The power conversion system (PCS) handles AC/DC and DC/AC conversion, with energy flowing into the batteries to charge them or being converted from the battery storage into AC power and fed into the grid. Suitable power device solutions depend on the voltages supported and the power flowing.

The battery management system (BMS) handles cell charging, balancing, and health monitoring, complemented by a microcontroller providing system control and communication. Essential elements to integrate ESS into larger systems.
