The movable plate 4 can slide left and right along the slide groove. The slide groove 5 is set along the inner wall of the second cavity 18. The charging seat also includes an elastic member 8. The fixed end of the elastic member 8 is connected to the seat body 1, and the movable end of the elastic member 8 is connected to the movable plate 4.

[0041] A switch 12 is also provided on the base body 1 of this embodiment, and the switch 12 is used to control the on and off of the charging circuit; a working indicator light 10 is also provided next to the switch 12, and the working indicator light is used to indicate the status of the switch 12. When the switch 12 is turned on, the working indicator light 10 is on, and when the switch 12 is turned off, the working indicator light 10 is off.

[0042] The charging contacts 7 of this embodiment include a first charging contact, a second charging contact, and a third charging contact. The first charging contact and the second charging contact are respectively used to connect to the positive and negative poles of the rechargeable battery. The first charging contact and the second charging contact are also connected to the charging circuit for charging. The third contact is used to detect the charging status of the rechargeable battery. The seat body 1 is also provided with a power interface 15, which is used to connect to the charging plug to supply power to the charging seat. The charging plug in this embodiment uses an existing plug that can determine the charging status. The third charging contact is connected to the charging plug through the charging circuit to provide the charging status of the rechargeable battery to the circuit board built into the charging plug. The charging plug controls the power supply of the corresponding charging slot according to the charging status of each rechargeable battery being charged.
