Abstract
The invention relates to a method for measuring an electric current of a battery () with multiple battery modules (), having the step of measuring a temperature related to the battery module (). According to the method, the temperature of a connector is first determined for at least one battery module () using the measured temperature and a temperature model, and the electric resistance of the connector is determined using a resistance model and the temperature of the connector. The electric voltage which drops at the connector is then measured, and the electric current flowing through the connector is calculated from the voltage. The invention additionally relates to a corresponding device and to a battery comprising such a device.
