Abstract
A relay unit includes a first busbar, a relay device, a second busbar, and a heat dissipation structure. The first busbar forms at least a part of an electric current path between a connecting portion, which is connected to a charging connector of an external charging device, and an in-vehicle battery. The relay device is provided on the first busbar. The second busbar forms at least a part of an electric current path between the in-vehicle battery and a power conversion device. The first busbar is branched at a branch portion from the second busbar, and includes at least a part of an electric current path extending from the branch portion to the connection portion via the relay device. The heat dissipation structure dissipates the heat from at least a part of the first busbar between the branch portion and the relay device.
