ABSTRACT:
A method for ascertaining the temperature in an electrical battery includes determining at least one temperature value at a temperature measuring point outside the battery in the vicinity of the battery; determining at least one electrical power value in dependence on a characteristic power variable associated with the operation of the battery; weighting the power values and the temperature values with an assigned weighting factor; and ascertaining the temperature in the electrical battery from an energy balance in dependence on the at least one weighted temperature value and the weighted electrical power values.
