Abstract
A method for charging a starter battery of a vehicle is disclosed, wherein the vehicle has at least one movable opening element and a motor unit, which is coupled to the opening element and is operable in a motor-powered drive mode to drive the opening element and in a generator mode to generate an electrical voltage, said method comprising: detecting the generator mode of the motor unit using the electrical voltage generated by the motor unit, comparing the generated electrical voltage with a specified voltage value, and establishing an electrical connection from the motor unit to the starter battery to charge the starter battery, if the generated electrical voltage is greater than the voltage value.
