摘要： A battery enclosure to house a battery pack of an electric vehicle includes a bottom plate, a battery pack including multiple batteries or battery modules, a frame enclosure at least partially surrounding the battery pack, the frame enclosure connected with the bottom plate, the frame enclosure including at least a first side wall and a second side wall, and multiple cross members each extending between the first side wall and the second side wall. The battery enclosure includes a top plate configured to cover the multiple structural cross members and at least a portion of the battery pack. The top plate is connected with the frame enclosure and includes multiple ridges protruding from a top surface of the top plate, each ridge defining a channel extending parallel to the top surface of the top plate, and each channel configured to facilitate flow of a heat transfer medium through the channel.
