Device for operating electrochemical energy storage device e.g. lithium ion battery, of battery management system, has cell controllers that are provided with charge compensation device to perform charge balance between storage cells

摘要

The device has several series-connected energy storage cells (10) with charge equalization line (20), which are provided with cell controllers. The cell controllers are provided with a charge compensation device which performs a charge balance between the energy storage cells via the charge equalization line. An independent claim is included for method for operating energy storage device.
