Claim 0:
1. A vehicle, wherein the vehicle comprises:
a switch control system, comprising:
a switching member,
a high voltage load,
a high voltage energy storage,
a bi-directional DC/DC-converter operatively connected to the switching member,
a high-voltage capacitor operatively connected to the high-voltage load, and
a low voltage energy storage operatively connected to the bi-directional DC/DC-converter,
wherein the switching member connects and disconnects the high voltage energy storage to and from the high voltage load,
wherein the bi-directional DC/DC-converter pre-charges the high-voltage capacitor to a predefined voltage value from the low voltage energy storage before the switching member is closed, and discharges the high-voltage capacitor to the low voltage energy storage when the switching member has been opened, and
wherein the predefined voltage value is set higher than the voltage of the high-voltage energy storage at one start moment of the vehicle, and wherein the predefined voltage value is set lower than the voltage of the high-voltage energy storage at a different start moment of the vehicle.
