Abstract
The battery pack includes a base having a heat dissipation wall, a switching device for controlling current having a plurality of electrode terminals, being disposed so as to be capable of transferring released heat to the heat dissipation wall, and a bus bar having a connection terminal that is connected to the switching device or a unit cell so as to enable energization. The connection terminal is disposed so as to be positioned in an area corresponding to a width of the switching device in a direction in which the electrode terminals are arranged in line and in an area extending to a periphery of the switching device in a direction orthogonal to the direction in which the electrode terminals are arranged in line.
Claims6
A battery pack comprising:
- a battery;
- a casing configured to accommodate the battery;
- a base formed as a part of the casing, the base having a heat dissipation wall;
- a switching device configured to control current and having a plurality of electrode terminals, the switching device being disposed so as to be configured to transfer heat to the heat dissipation wall;
- and
- a bus bar disposed so as to be configured to transfer heat to the heat dissipation wall, the bus bar having a connection terminal connecting the switching device and an electrical component, the connection terminal of the bus bar being entirely located in an area defined by (i) a width of the switching device in a direction in which the electrode terminals are arranged along the switching device, and (ii) a periphery of the area defined by the location of the connection terminal, which is located in a direction extending away from the switching device and orthogonal to the direction in which the electrode terminals are arranged in line.
