The present invention provides a battery box, including a battery and an electronic device electrically connected to the battery. The battery box further includes a lower box body, including a first box part and a second box part, where the second box part is integrally connected to the first box part; a first top cover, hermetically and removably mounted in a height direction above the first box part and forming a sealed first space with the first box part, where the first space accommodates the battery; and a second top cover, hermetically and removably mounted in the height direction above the second box part and forming a sealed second space with the second box part, where the second space accommodates the electronic device electrically connected to the battery, and the second top cover is disposed independent of the first top cover. In the battery box according to the present invention, the second top cover is disposed independent of the first top cover, so that only the second top cover needs to be dismantled separately when repairing or replacing the electronic device in the second space. This reduces repair cost and repair difficulty of the battery box.
