This application provides a power module, a power supply system, a vehicle, and a photovoltaic system. The power module includes a first metal layer-coated substrate, a plurality of chips, and a first connection piece. A first electrode of each chip is electrically connected to a first metal layer of the first metal layer-coated substrate. The first connection piece includes a first main body part and a plurality of first contact parts. A second electrode of each of the plurality of chips is in contact with at least one of the first contact parts. There is a part of the first main body part between at least one pair of adjacent first contact parts. In this application, a current flowing out from the chip may directly flow to the first main body part through the first contact part. In this way, a current flow path is shortened. The chips are connected in parallel by using the first connection piece, so that parasitic inductance of the power module can be reduced, and current equalization of the power module can be improved.
