Abstract:
A method is provided for determining the charge state of a motor vehicle battery. An electrical voltage of the motor vehicle battery is detected and the electrical charge state of the motor vehicle battery is determined on the basis of the detected voltage of the motor vehicle battery. According to the method, the temperature of the motor vehicle battery is detected using a sensor that is separated spatially from the motor vehicle battery, and the charge state of the battery is determined on the basis of the detected voltage of the motor vehicle battery and on the basis of the detected temperature of the motor vehicle battery.
