Abstract
The disclosure relates to a method for controlling an electrical system of an electrically drivable motor vehicle, wherein the electrical system includes at least one lead battery and at least one lithium battery. Initially, a lower and a first upper threshold value for a state of charge of the lithium battery are determined. Then, a second upper threshold value which is higher than the first upper threshold value is determined. During the driving operation of the motor vehicle, a state of charge of the lithium battery is set between a lower and a second upper threshold value. When the motor vehicle is switched off, the state of charge of the lithium battery is determined. If the state of charge of the lithium battery is higher than the first upper threshold value, the state of charge of the lithium battery is lowered to the first upper threshold value.
