Abstract
The invention discloses a battery case and a battery device. An intermediate beam is connected to at least one side beam by a connecting piece, and a first groove is disposed on a side beam corresponding to a reference end. After the connecting piece is accommodated in the first groove, the intermediate beam and the corresponding side beam can be fixed and connected. Accordingly, the effective connection between the intermediate beam and the side beams is implemented, damage to the intermediate beam and the side beams in the connection process is prevented, and meanwhile the effects of the connection on the single batteries can be prevented, thereby improving the reliability of the battery device.
