[0044] At present, the number of new energy vehicles is gradually increasing, and the battery capacity and charging power requirements of different types of new energy vehicles are different. The traditional charging pile usually maintains constant power output, which causes waste of power when charging new energy vehicles with low charging power requirements, and prolongs the charging time when charging new energy vehicles with high charging power requirements. Therefore, the charging pile technology is gradually popularized, and the charging pile can flexibly allocate charging modules according to the actual charging demand of new energy vehicles, improve the charging efficiency and equipment utilization.

[0045] The charging pile usually comprises a plurality of output terminals, which are generally referred to as charging guns. The applicant has found through research that, according to the current power distribution method of the charging pile and the power distribution structure of the charging pile, when one charging gun is used, the remaining charging modules can distribute their power to the charging gun according to the charging power of the new energy vehicle; when a plurality of charging guns are used, taking the case of two charging guns being used at the same time as an example, due to the unreasonable design of the power distribution structure, it is difficult to distribute the power of the idle charging modules to the charging guns at the edge position, and the power of the idle charging modules is distributed to the charging guns at the middle position. This situation leads to the power of the idle charging modules being unable to be accurately distributed, thereby causing some of the new energy vehicles to have low charging efficiency or fast and slow charging speed when charging, which affects the charging quality.

[0046] In view of this, the utility model provides a flexible charging pile to solve the above technical problems.

[0047] Please refer to Figures 1 to 4 and Figure 6 In an embodiment of the utility model, the flexible charging pile 1000 comprises a first matrix output module 1, a control unit 4 and a plurality of charging modules 3. The first matrix output module 1 comprises a plurality of output copper bar groups 11 arranged at intervals, and one output copper bar group 11 is electrically connected to one charging module 3. The first matrix output module 1 further comprises a plurality of direct current scheduling copper bars 12 and a plurality of switch pieces 13. The plurality of direct current scheduling copper bars 12 are arranged in parallel at intervals. Each output copper bar group 11 is electrically connected to the remaining output copper bar groups 11 through the plurality of direct current scheduling copper bars 12. The switch piece 13 is installed between each output copper bar group 11 and the direct current scheduling copper bar 12. The control unit 4 is electrically connected to the switch piece 13 and is used to control the opening and closing of the switch piece 13.

[0048] Specifically, the control unit 4 controls the opening and closing of the switch piece 13, so that the plurality of output copper bar groups 11 can be combined through the direct current scheduling copper bar 12, thereby realizing the orderly dynamic distribution of the power in the plurality of charging modules 3. Please refer to Figure 6For example, each charging module 3 corresponds to supply current to one group of output copper bars, and the AC power supply is used to supply AC power to each charging module 3. The AC power input into the charging module 3 is converted into DC power by the charging module 3 and output to the corresponding output copper bar group 11. The output copper bar group ① is electrically connected to the output copper bar group ②, the output copper bar group ③ and the output copper bar group ④ through the DC scheduling copper bar 12. The K12 (switch 13, in this embodiment, the switch 13 in different circuits is represented in the form of "letter K + number", the same below) is arranged between the output copper bar group ① and the output copper bar group ②, the K13 is arranged between the output copper bar group ① and the output copper bar group ③, and the K14 is arranged between the output copper bar group ① and the output copper bar group ④. The output copper bar group ② is also electrically connected to the output copper bar group ③ and the output copper bar group ④ through the DC scheduling copper bar 12. The K23 is arranged between the output copper bar group ② and the output copper bar group ③, and the K24 is arranged between the output copper bar group ② and the output copper bar group ④. On this basis, the output copper bar group ③ and the output copper bar group ④ are electrically connected through the DC scheduling copper bar 12, and the K34 is arranged between them. Each switch 13 is electrically connected to the control unit 4. The switch 13 includes one of the DC contactor and the relay. In this embodiment, the DC relay is adopted. The attraction of the DC contactor is controlled by the control unit 4 to control the combination between different output copper bar groups 11. For example, if the output copper bar group ① and the output copper bar group ② are used to charge the new energy vehicle, if the power of the charging module ④ needs to be distributed to the output copper bar group ①, and the power of the charging module ③ needs to be distributed to the output copper bar group ②, the K14 and the K23 are closed by the control unit 4, and the K12, the K13, the K24 and the K34 are kept in the open state, so that the power distribution is completed. If the power of the charging module ③ and the charging module ④ needs to be distributed to the charging module ①, the K13 and the K14 are closed, and the K12, the K23, the K24 and the K34 are kept in the open state. When the output copper bar group ①, the output copper bar group ② and the output copper bar group ③ are used at the same time, if the power of the charging module ④ needs to be distributed to the output copper bar group ②, the K24 is closed, and the K12, the K13, the K14, the K23 and the K34 are kept in the open state, so that the power of the charging module ④ can be accurately distributed to the output copper bar group ② without flowing to other output copper bar groups 11. In this way, the power in each charging module 3 can be dynamically distributed by opening or closing different DC contactors. It should be noted that the number of output copper bar groups 11 and charging modules 3 is not limited to four groups. It can be eight groups, ten groups, twelve groups or more. The specific number is set according to the actual demand. In addition, the DC scheduling copper bar 12 can realize Figure 6 There are various installation methods of the circuit in the flexible charging pile 1000. The space and cost requirements of the flexible charging pile 1000 can be set according to the actual demand.

[0049] By controlling the opening and closing of the different switch pieces 13 by the control unit 4, the different groups of output copper bar groups 11 can be electrically connected through the direct-current scheduling copper bar 12 to distribute the idle charging module group 3 to the output copper bar group 11 in use, so as to dynamically adjust the power, current or voltage of the output copper bar group 11 in use, thereby avoiding affecting the charging quality of the new energy vehicle.
