Abstract
An energy store has at least one energy storage module with a plurality of energy storage cells. The energy storage cells are each electrically coupled to a monitoring unit. Each monitoring unit is designed to discharge the respective energy storage cell by use of a specified symmetry current in an active operating state. The method operates the energy store by performing the acts of: detecting an open-circuit voltage of each energy store cell and determining a discharge duration for each energy storage cell as a function of the open-circuit voltage of the energy storage cell and a specified target discharge voltage value; and controlling each monitoring unit in order to discharge the respective energy storage cell by use of the specified symmetry current for the discharge duration associated with the respective energy storage cell.
