When the charging process fails to meet the requirements and the placement is incorrect, timely intervention can be made to stop the plug from being inserted further, preventing the plug from contacting the battery and causing damage, and at the same time preventing the damage to the battery from causing harm to the surrounding staff.

[0016] (3) The invention, when the limit of the limit plate is released, the limit on the elastic telescopic cover will be released, and when the limit of the elastic telescopic cover is released, it will move toward the middle to seal the chassis, so as to avoid the battery explosion from causing danger to the surrounding personnel and at the same time avoid affecting the surrounding equipment. When the limit of the limit plate is released, the limit on the elastic telescopic cover will be released, and when the limit of the elastic telescopic cover is released, it will move toward the middle to seal the chassis, which can reduce the air entering the chassis and suppress the development of the fire. At the same time, it can also prevent flames and smoke from entering the outside area and avoid damage to the server, storage device, etc. of the external equipment. At the same time, it can also prevent toxic gases from entering the adjacent working areas and protect the personnel in these areas from being harmed by toxic gases.
