The charging pile body outputs power to the electric vehicle through the power output end to charge the electric vehicle.

[0023] The second plug-in connector is located in the groove, and the output end of the second plug-in connector is connected to the power input / output end of the charging pile body of the charging pile body. The input end of the second plug-in connector is externally connected to the power cabinet 21 or the first plug-in connector included in the second charging pile.

[0024] It should be noted that the number of the first plug-in connector and the second plug-in connector included in the charging pile can be set according to the actual situation. The number of the first plug-in connector and the second plug-in connector can be the same or different. The embodiments of the present disclosure do not make special limitations on this. The type of the charging pile can be, but is not limited to, a wall-mounted or floor-mounted charging pile.

[0025] The charging pile can achieve a "hand in hand" connection through the first plug-in connector and the second plug-in connector, realizing the flexible expansion of the charging pile. Moreover, the expansion of the charging pile is no longer limited to the conventional layout. The charging pile can be extended to any position for installation and can be freely disassembled. Figure 1 The second plug-in connector of the charging pile b in is connected to the first plug-in connector of the charging pile a, and the charging pile a supplies power to the charging pile b. The first plug-in connector of the charging pile b is connected to the second plug-in connector of the charging pile c, and the charging pile b supplies power to the charging pile c. If the charging pile a is provided with n1 first plug-in connectors, the charging pile a can also be connected to the charging pile a + 1, the charging pile a + 2,..., the charging pile a + n1, etc.; similarly, if the charging pile b is provided with n2 first plug-in connectors, the charging pile b can be connected to the charging pile b + 1, the charging pile b + 2,..., the charging pile a + n2, etc.

[0026] In this embodiment, by adding the first plug-in connector and the second plug-in connector to the charging pile, the charging pile can be conveniently and flexibly connected to other charging piles to realize the expansion of the charging pile. The expansion of the charging pile is not limited by the number of wiring ports reserved in the power cabinet, which can meet the charging needs of more electric vehicles. There is no need to design, construct, install and wire, and it also has the advantages of low implementation cost and not occupying a large area. Moreover, the first plug-in connector and the second plug-in connector are arranged in the groove protected by the protective cover, which can achieve the purpose of waterproofing and dustproofing and improve the charging safety.

[0027] It can be understood that the layout relationship between the first plug-in connector, the second plug-in connector and the groove can be set according to the actual needs. For example, the first plug-in connector and the second plug-in connector can be both arranged in one groove; or all the first plug-in connectors are arranged in one groove, and all the second plug-in connectors are arranged in another groove; or each groove is provided with one first plug-in connector, and each groove is provided with one second plug-in connector. At this time, the number of grooves of the second plug-in connector is equal to the total number of the first plug-in connector and the second plug-in connector. This layout method can independently waterproof and dustproof each plug-in connector.

[0028] In one embodiment, the first plug-in connector and the second plug-in connector are respectively disposed on the front and back of the housing, that is, the groove provided with the first plug-in connector and the groove provided with the second plug-in connector are respectively arranged on the front and back of the housing, so as to facilitate the user to expand other charging piles.

[0029] In one embodiment, when there are multiple grooves, the grooves are arranged in an array. If multiple grooves provided with the first plug-in connector are disposed on the front of the housing, the grooves on the front of the housing are arranged in an array. If multiple grooves provided with the second plug-in connector are disposed on the back of the housing, the grooves on the back of the housing are arranged in an array. The array can be a matrix array or a circular array, and the embodiments of the present disclosure do not make special limitations thereto.

[0030] The so-called front side is the side of the charging pile where the charging gun is provided. The charging gun is connected to the power output terminal, and the user can charge the electric vehicle through the charging gun.

[0031] In one embodiment, the interface of the output end of the first plug-in connector faces the bottom of the charging pile. That is, the interface of the first plug-in connector is set to be installed downward, so as to further protect the first plug-in connector and the charging pile from water and dust.

[0032] In one embodiment, the interface of the input end of the second plug-in connector faces the bottom of the charging pile. That is, the interface of the second plug-in connector is set to be installed downward, so as to further protect the second plug-in connector and the charging pile from water and dust.

[0033] The interface of the first plug-in connector can adopt Figure 2 the quick plug male head shown. Correspondingly, the interface of the second plug-in connector can adopt Figure 3 the quick plug female head adapted to the quick plug male head shown. The interface of the first plug-in connector can adopt Figure 3 the quick plug female head shown. Correspondingly, the interface of the second plug-in connector can adopt Figure 2 the quick plug male head adapted to the quick plug female head shown. Of course, the first plug-in connector and the second plug-in connector can also adopt other types of interfaces, and the embodiments of the present disclosure do not make special limitations thereto.

[0034] Connecting the charging pile with the quick plug male head and the quick plug female head is more time-saving and convenient compared with the original complex wiring method.

No matter which wiring method is adopted, the copper bar can ensure the power supply and power taking stability of the first plug-in connector and the second plug-in connector, and also increase the safety of the charging pile and the electric vehicle.

[0038] In one embodiment, the input end of the first plug-in connector is connected to the output end of the first plug-in connector through a length-adjustable cable, and the output end of the first plug-in connector is removably received in the groove. When the charging pile needs to be expanded, the output end of the first plug-in connector can be pulled out to externally connect other charging piles (the first charging pile) to supply power to other charging piles, which is convenient to operate.

[0039] In one embodiment, the input end of the second plug-in connector is connected to the output end of the second plug-in connector through a length-adjustable cable, and the input end of the second plug-in connector is removably received in the groove. When the charging pile needs to be expanded, the input end of the second plug-in connector can be pulled out to externally connect a power supply cabinet or other charging piles (the second charging pile), and the power supply cabinet or other charging piles supply power to this charging pile, which is convenient to operate.

[0040] In one embodiment, the housing is further provided with a storage box; the storage box is used for storing the length-adjustable cable; the output end of the first plug-in connector is externally connected to the second plug-in connector included in the first charging pile through a cable; or, the input end of the second plug-in connector is externally connected to the power supply cabinet or the first plug-in connector included in the second charging pile through a cable.

[0041] In this embodiment, a length-adjustable cable is provided in the storage box of the housing, which can facilitate the expansion of the charging pile at any time.

[0042] In one embodiment, the bottom of the housing is provided with pulleys. The pulleys can facilitate the movement of the charging pile, so that the installation and disassembly of the charging pile are not restricted by the geographical location, which is more convenient.

[0043] In one embodiment, the bottom of the housing is provided with fixing holes for fixing the charging pile. When encountering some special scenarios, such as slopes, corners or places with limited open space and narrow space, the charging pile can well adapt to this scenario.

The power supply cabinet or other charging piles charge the charging battery through the power input end, and when the user needs to charge the electric vehicle, the charging battery charges the electric vehicle through the power output end. The charging battery can be but not limited to a lead-acid battery.

[0045] In this embodiment, the charging pile can still charge the electric vehicle through the charging battery when there is no external power supply. The charging pile can also realize off-peak power taking and can transmit power to the power grid for differential charging and discharging.

[0046] In one embodiment, the top of the housing further includes a solar panel, and the solar panel can charge the charging battery. Charging the charging battery with green energy can reduce the overall power consumption of the charging pile.
