An electrical energy store has a plurality of storage modules, each of which has at least one temperature sensor string having a temperature sensor in the form of a temperature-dependent resistor for measuring the storage module temperature, and a battery control unit, which, based on the resistance values of the temperature sensor strings, determines the temperatures at the respective temperature sensors. The battery control unit is designed to determine a respective storage module type based on the measured resistance values of the temperature sensor strings. A method for identifying a storage module type, includes the steps: detecting a resistance value of at least one temperature sensor string having a temperature sensor, determining the temperatures present at the respective temperature sensors via a battery control unit on the basis of the resistance values of the temperature sensor strings, and determining a storage module type on the basis of the resistance value of the at least one temperature sensor string per storage module.
