A vehicle power distribution circuit (14) for connecting between an energy store (2) and a power line (8) connected to a generator or DC/DC-Converter (9). The circuit (14) has a charging line (7) connecting between the energy store (2) and the power line (8) for charging the energy store (2) when a forward voltage is applied by the generator or DC/DC-Converter (9). A protection switch (6) is provided in the charging line (7) and is openable for preventing conduction of current through the protection switch (6) in response to a drop in voltage on the power line (8). An ideal diode arrangement (13) is provided in parallel to the protection switch (6) in the charging line (7) for conducting the forward current from the generator or DC/DC-Converter (9) to the energy store (2). The ideal diode arrangement (13) prevents the conducting of a reverse current when a reverse voltage is applied.
