  "textContent": "This application provides a vehicle-mounted power supply apparatus and a vehicle. The vehicle-mounted power supply apparatus includes a power conversion circuit, and an upper-layer PCB, a lower-layer PCB, and a heat sink that are stacked in and fastened to a bottom housing. The heat sink, the upper-layer PCB, and the lower-layer PCB are stacked, so that internal space occupied in the vehicle-mounted power supply apparatus can be reduced. In addition, these components are fastened to the bottom housing, so that structural strength of the vehicle-mounted power supply apparatus is strong. The power conversion circuit receives external power supply through a power port, outputs a first direct current through a first direct current port, and outputs a second direct current through a second direct current port. The lower-layer PCB is electrically connected to the first direct current port, and the upper-layer PCB is electrically connected to the second direct current port and the power port. The upper-layer PCB and the lower-layer PCB that are stacked are electrically connected to different ports separately Compared with a solution in which the different ports are electrically connected to one PCB, electrical port arrangement is more flexible, so that safety of electrical isolation of the vehicle-mounted power supply apparatus is higher",
