Module-level battery controller E² D100

The E² D100 module-level battery controller is a groundbreaking solution that deeply integrates power electronics technology and advanced control technology. It addresses critical challenges such as capacity loss and safety risks caused by battery cell inconsistency after grouping.

Key innovations include:

· Integrated design combining the power electronics converter and battery management unit (BMU)

· Conventional charge and discharge management functions, enhanced with:

S0X balancing technology (independently developed);

Active safety warning technology based on EIS (Electrochemical Impedance Spectroscopy).

This controller ensures optimal performance, enhanced safety, and extended battery life, making it a vital component for modern energy storage systems.
