Battery With Individual Cell Management

Patent No. EP2681797 (titled "Battery With Individual Cell Management") was filed by Commissariat Lnergie Atomique ET AUX Nergies Alternatives on Mar 2, 2012. The application was issued on Nov 14, 2018.

Patent Summary

A battery management system that integrates control and diagnostic functions directly into the battery architecture, eliminating the need for external DC-DC converters and diagnostic devices. The system comprises a modular battery structure with integrated switches and control circuits, where each module is powered by its own cells and can operate independently. The control circuits are powered by the battery cells themselves, enabling local control and diagnostic functions without the need for external power supplies. This architecture enables real-time monitoring and control of battery performance, as well as advanced diagnostic capabilities, including cell-level current measurement and state-of-charge estimation.
