Battery pack

A battery pack, comprising:

• a battery module having a bottom surface and a top surface;
• the battery module further having a plurality of flow channels extending through the battery module from the top surface to the bottom surface;
• a base assembly adapted to hold the battery module at a tilted position thereon, the base assembly having a sheet member with a bottom wall, first and second upwardly slanted top walls, a first inner side wall, a second inner side wall, a first inner end wall, a first end, and a second end;
• the first and second upwardly slanted top walls being disposed apart from one another and extending in a first direction, the first direction extending from the first end to the second end of the sheet member;
• the first inner side wall being coupled directly to and between the bottom wall and the first upwardly slanted top wall and extending in the first direction, the second inner side wall being coupled directly to and between the bottom wall and the second upwardly slanted top wall and extending in the first direction, the first inner end wall being coupled directly to and between the first and second inner side walls and extending upwardly from the bottom wall, the first and second upwardly slanted top walls further extending at an acute angle relative to the bottom wall;
• the bottom wall being disposed between the first and second inner side walls and extending in the first direction;
• the bottom surface of the battery module being disposed directly on and directly contacting the first and second upwardly slanted top walls such that the bottom surface of the battery module is tilted and disposed at the acute angle relative to the bottom wall of the base assembly in the first direction and the plurality of flow channels in the battery module fluidly communicate with a first flow path, the first flow path being at least partially defined between the bottom wall of the base assembly, the first and second inner side walls, the first inner end wall, and the bottom surface of the battery module;
• a cover assembly coupled to the base assembly such that battery module is disposed within an interior region defined by the cover assembly and the base assembly, the cover assembly having a top wall extending horizontally, the top wall of the cover assembly extending substantially parallel to the bottom wall of the base assembly, and a top surface of the battery module being disposed at an acute angle relative to the top wall of the cover assembly in a second direction opposite to the first direction;
• and a second flow path being defined between the top surface of the battery module and the top wall of the cover assembly;
• an electronic assembly being disposed directly on the base assembly proximate to the second end of the base assembly such that a portion of the first flow path extends underneath the electronic assembly;
• an electric fan assembly being disposed in the interior region and between the battery module and the electronic assembly in the first direction;
• the electric fan assembly fluidly communicating with the first flow path;
• the electric fan assembly being adapted to urge air to flow through an inlet aperture of the cover assembly, and through the second flow path, and the plurality of flow channels of the battery module, and the first flow path, and to exit an outlet aperture of the cover assembly.
