Abstract

An energy store has a plurality of electrical energy storage cells, which are connected electrically in series or parallel and are combined to form an energy storage module. Cooling plates are arranged between the energy storage cells and into which coolant or refrigerant can be introduced. A plurality of emergency switching devices are provided, each of which is associated with an energy storage cell and one or two cooling plates. The emergency switching devices allow the coolant or refrigerant to flow into the associated cooling plates only if a temperature of the associated energy storage cell exceeds a defined limit temperature.
