摘要： The present invention provides a battery box, including a lower box body. The lower box body includes: a first plate including a bottom wall and a peripheral wall that is connected to the peripheral edge of the bottom wall and extending upwards, where the bottom wall and the peripheral wall together form an accommodating space that opens upwards along a height direction; and a second plate that is fastened under the bottom wall and that forms, together with the bottom wall, an inlet flow path, an outlet flow path, and a main flow path communicating with both the inlet flow path and the outlet flow path, where the main flow path includes a first main flow path, a second main flow path, and a plurality of parallel branch flow paths that communicate with both the first main flow path and the second main flow path. In the battery box of the present invention, the first plate and the second plate together form the lower box body and a heat exchange flow path. The box body and the heat exchange flow path are integrated together, thereby reducing an overall weight. In addition, the heat exchange flow path is provided externally, thereby effectively avoiding impact of liquid leakage from the heat exchange flow path on batteries inside the battery box. Furthermore, the main flow path formed by the first plate and the second plate allows a short heat exchange path and uniform heat exchange, thereby improving a heat exchange effect.
