Abstract: A vehicle-mounted charging apparatus and a vehicle. The vehicle-mounted charging apparatus includes a power conversion circuit and a housing. The housing is configured to accommodate the power conversion circuit. The power conversion circuit is configured to convert an input power supply into at least one of a first direct current or a second direct current. A plurality of electrical interfaces is disposed on an electrical interface mounting surface in the housing. The plurality of electrical interfaces includes one input power interface, two first direct current output interfaces, and one second direct current output interface. The input power interface is configured to be connected to an input end of the power conversion circuit. The plurality of electrical interfaces is disposed on a same surface, so that the external interfaces are appropriately arranged and highly integrated. This facilitates a vehicle layout, improves assembly simplicity.

Abstract: A packaging structure is provided and may include a housing and a power component. The power component is disposed inside the housing. The housing may include a top cover and a bottom housing. The top cover may have a first heat transfer medium channel inside. The bottom housing may have a second heat transfer medium channel inside. The power component may include a first circuit board and a second circuit board. At least one first heating device may be disposed on the first circuit board. The first heating device may press against an inner wall of the top cover. At least one second heating device may be disposed on the second circuit board, and the second heating device may press against an inner wall of the bottom housing. When the foregoing structure is used, high power density and high heat dissipation efficiency can be achieved.
