Abstract: Power system for an electric vehicle comprising a high voltage bus connectable to a high voltage battery, a low voltage bus connectable to a low voltage battery, a first converter having a high voltage terminal configured to be connected to the high voltage bus, and a low voltage terminal configured to be connected to the low voltage bus, a second converter having a power terminal configured to be connected to a power source, and a low voltage terminal configured to be connected to the low voltage bus, a current sensor configured to determine an output current at the low voltage terminal of the first converter, a control unit controlling the second converter based on the determined output current, whereby the control unit is configured to control the second converter to supply a current to the low voltage bus so as to reduce the determined output current.
