An electrical power supply network for a motor vehicle, including at least one high-voltage battery and one low-voltage battery, wherein at least one DC/DC converter is arranged between the high-voltage battery and the low-voltage battery, which is designed such that the high-voltage battery charges the low-voltage battery, and at least one solar module, which is connected to the low-voltage battery via a DC/DC converter, wherein at least one control device is associated with the low-voltage battery which is designed such that an SOC value of the low-voltage battery is ascertained, wherein during a vehicle standstill, the high-voltage battery is charged from the low-voltage battery via a DC/DC converter until the SOC value of the low-voltage battery reaches a first threshold value. Also disclosed is a method for distributing electrical energy in such a power supply network.
