Method for operating energy storage with multiple energy storage units, involves coupling energy storage units over connecting element in electric manner

摘要

The method involves coupling the energy storage units (11) over a connecting element in an electric manner. An energy storage power, an energy storage current and a voltage of the energy storage units are detected by a measuring unit (200). The sum voltage is determined depending on the voltages of the energy storage units. An independent claim is also included for a device for operating an energy storage with multiple energy storage units.
