Abstract
A method for charging the starter battery of a motor vehicle at a voltage source includes charging the starter battery after a traction battery of the vehicle has been charged up to a defined value. The starter battery is charged if a charge state of the starter battery is established that is below a defined threshold value. If the charge state of the starter battery is of such a low level, the starter battery is charged until one or more defined termination conditions are fulfilled. The termination conditions may include the total charging period since the low charge state of the starter battery has been established exceeds a defined threshold value and/or the total time period charging the traction battery and the starter battery at the voltage source exceeds a defined threshold.
