[0051] like Figure 8 As shown, in the illustrated embodiment, the rear end of the power terminal 12 extends from the insulating shell 13 for electrical connection to the power line 3.

[0052] like Figure 8 As shown in the illustrated embodiment, the charging dock 1 further includes a power cord 3, which is electrically connected to the rear end of the power terminal 12. The power cord 3 is used to electrically connect the power terminal 12 of the charging dock 1 to the charger 2 to transmit charging current between the charging dock 1 and the charger 2.

[0053] like Figure 8 As shown in the illustrated embodiment, the charging base 1 further includes a grounding terminal 14 disposed within the insulating housing 13 for mating with the mating grounding terminal (not shown) of the charging gun 4.

[0065] like Figures 1 to 8 As shown in the illustrated embodiment, there is no physical signal connection between the charging dock 1 and the charger 2. The signal transmission between the charging dock 1 and the charger 2 is achieved entirely through wireless communication between the first wireless communication module 10 and the second wireless communication module 20.

[0066] like Figures 1 to 8 As shown, in another exemplary embodiment of this utility model, a charging device is also disclosed. The charging device includes: a charging base 1, a charger 2, and a power cord 3. The charging base 1 is adapted to dock with a charging gun 4 and includes a first wireless communication module 10 adapted to detect whether the charging base 1 has docked with the charging gun 4. The charger 2 is used to charge a rechargeable battery (not shown) and includes a second wireless communication module 20 adapted to communicate wirelessly with the first wireless communication module 10. The power cord 3 is connected between the charging base 1 and the charger 2 for transmitting charging current between the charging base 1 and the charger 2. After the charging base 1 docks with the charging gun 4, the first wireless communication module 10 sends a docking completion message to the second wireless communication module 20. Upon receiving the docking completion message, the charger 2 connects the charging circuit between the charger 2 and the rechargeable battery to charge the battery.

[0067] like Figures 1 to 8 As shown in the illustrated embodiment, there is no physical signal connection between the charging dock 1 and the charger 2. Signal transmission between them is entirely achieved through wireless communication between the first wireless communication module 10 and the second wireless communication module 20.

A charging device, characterized in that, include: A charging dock (1) is adapted to dock with a charging gun (4) and includes a first wireless communication module (10) adapted to detect whether the charging dock (1) has docked with the charging gun (4); Charger (2), for charging the rechargeable battery and including a second wireless communication module (20) adapted to communicate wirelessly with the first wireless communication module (10); and A power cord (3) is connected between the charging dock (1) and the charger (2) for transmitting charging current between the charging dock (1) and the charger (2). After the charging dock (1) is connected to the charging gun (4), the first wireless communication module (10) sends a connection completion message to the second wireless communication module (20). After receiving the connection completion message, the charger (2) connects the charging circuit between the charger (2) and the rechargeable battery to charge the rechargeable battery.
