High-Voltage ESS Reference Development
Platform from eInfochips

Electrification is not just about electrifying cars. It is about end-to-end energy optimization for the entire infrastructure. Therefore, the industry is witnessing tremendous market growth in terms of adopting energy storage systems to be able to make the infrastructure more robust, more reliable and more efficient. 

There have been a lot of challenges when it comes to the safety, security, robustness and scalability of the battery systems. Battery Management System (BMS ) is the first line of defense to monitor, balance and optimize the battery health & performance in real-time, allowing improved power system efficiency, lifetime and safety of battery applications.

eInfochips recently partnered with NXP Semiconductors for the design and development of a 1500V BMS reference development platform suitable for high-voltage applications.

NXP ESS is a production-grade battery management system reference development platform. It is an IEC 61508 and IEC 60730 compliant architecture of up to 1500V intended for a variety of high-voltage battery management solutions for utility, commercial & industrial and residential energy storage. NXP ESS is a complete hardware, software and safety package encompassing product safety life-cycle libraries and documentation considering IEC 61508 and UL 9540.
