Abstract

See full text

A vehicle power supply system (100), comprising: —a vehicle battery (111) with a charging voltage, —a DC-to-DC converter (130) comprising two first connection terminals (110) connected to the vehicle battery (111) and two second connection terminals (120) for connecting an external charger to recharge the vehicle battery (111) or for connecting an external battery to be recharged, wherein, in a first mode in which an external charger is connected to the two second connection terminals (120), the voltage V2 between the two second connection terminals (120) is an input voltage of the converter and the voltage V1 between the two first connection terminals (110) is an output voltage of the converter, wherein, in a second mode in which an external battery to be recharged is connected to the two second connection terminals (120), the voltage V1 between the two first connection terminals (110) is an input voltage of the converter and the voltage V2 between the two second connection terminals (120) is an output voltage of the converter, wherein the system also includes means for determining at least the voltage V2 between the two second connection terminals (120) and preferably also the voltage V1 between the two first connection terminals (110), and wherein the DC-to-DC converter (130) is controlled so that the output voltage of the converter is equal to the charging voltage of the vehicle battery (111) in the first mode and to a charging voltage of the external battery in the second mode.
