Abstract: A power converter is provided. The power converter includes a housing, a heat dissipation module, and a first circuit board. The housing forms a receiving space, wherein the housing includes a first housing port and a second housing port. The heat dissipation module is detachably connected to the housing, and disposed in the receiving space. The heat dissipation module includes an inner path that communicates the first housing port with the second housing port. Working fluid enters the inner path via the first housing port. The working fluid leaves the inner path via the second housing port. The first circuit board includes a first circuit board body and a first heat source, wherein the first heat source is disposed on the first circuit board body, and the first heat source is thermally connected to the inner path of the heat dissipation module.

Abstract: An on-board charging device includes an AC connector, an AC to DC converter and a detection circuit. The AC connector is configured to be connected to an electric vehicle supply equipment (EVSE), so that a protective earth terminal of EVSE is electrically connected to a protective earth terminal of the on-board charging device. The AC to DC converter is electrically connected to the AC connector, and the AC to DC converter is configured to convert an AC voltage provided by the EVSE into a DC voltage. The AC to DC converter has a reference ground terminal. The detection circuit outputs a detection voltage based on the voltage difference between the protective earth terminal of the on-board charging device and the reference ground terminal of the AC to DC converter. The detection voltage reflects whether the protective earth terminal of the EVSE is abnormal or not.
