Infineon Technologies Residential Energy Storage Systems (ESS)

Infineon Residential Storage Solutions (ESS) offers various products to create and manage resilient energy infrastructures. Infineon's distinctive expertise in energy generation, power conversion, transmission, and battery management makes it an ideal natural partner to advance Energy Storage Solutions, especially in terms of efficiency, innovation, performance, and optimal cost.

The Infineon 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 provide a wide range of excellent options for energy storage system designs.

Battery-based ESS technology can react to power dropouts in under a second, using 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 behind the meter.

Structure of Energy Storage Systems

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) manages cell charging, balancing, and health monitoring. The BMS is complemented by a microcontroller that supplies system control and communication. These are essential elements to integrate ESS into larger systems.
