[0010] Further, the number of charging modules of at least one power module in the multiple power modules of the subsystem is one.

[0011] Further, the number of power modules is at least two.

[0012] Further, the number of output ports is at least two.

[0013] Further, when the number of charging loops is greater than the number of output ports, at least one output port is provided with a plurality of output branches respectively connected to one charging loop, and each output branch is provided with a DC contactor; when the number of charging loops is equal to the number of output ports, each output port is connected to each charging loop one by one, and a DC contactor is arranged between the connected output port and charging loop.

[0014] Further, the number of subsystems is a plurality, and the number of output ports of each subsystem is the same.

[0015] The beneficial effects of the technical scheme are as follows:

[0016] 1. In the polygon matrix charging scheduling circuit structure of the present application, convenient expansion can be performed, the subsystems in the multi-subsystem structure can be replaced, the number of power modules and output ports in the subsystems can be adjusted, or the number of charging modules in the power modules and the distribution can be adjusted, when the number of charging loops changes, the number of paths connected to each output port of each subsystem can also be adjusted, which is relatively flexible and easy to upgrade and expand.

[0017] 2. Only two DC contactors are needed to control the on-off from the charging loop to any power module, so that fewer devices are used when the charging system is built. BRIEF DESCRIPTION OF DRAWINGS

[0025] The present application will be further described below with reference to the accompanying drawings and embodiments.

[0026] like Figures 1-7 The diagram shows a polygonal matrix charging scheduling circuit structure, which includes multiple charging loops and at least one subsystem with the circuit structure arranged in a polygonal pattern.

[0027] The subsystem includes multiple power modules, multiple output ports, and multiple DC contactors.

[0028] Each power module is located at multiple vertices of the polygon. Each power module includes several charging modules. The number of power modules in a single subsystem is at least two, and at least one of the power modules has one charging module.

[0029] Each subsystem has at least two output ports. Each output port is connected to at least one charging circuit, and the output ports are located at multiple vertices of the polygon. The number of output ports does not exceed the number of charging circuits.

[0030] When the number of charging circuits is greater than the number of output ports, at least one output port is provided with multiple output branches that are respectively connected to a charging circuit, and each output branch is provided with a DC contactor; when the number of charging circuits is equal to the number of output ports, each output port is connected to each charging circuit in a one-to-one correspondence, and a DC contactor is provided between the connected output port and the charging circuit.

[0031] When there are multiple subsystems, each subsystem has the same number of output ports.

[0032] For each DC contactor, a DC contactor is provided on each side of the polygon. A single line is provided between any power module and output port located at a non-adjacent vertex of the polygon, and a DC contactor is provided on each single line. The single line is located inside the polygon.

[0033] Below are several specific examples of this polygonal matrix charging scheduling circuit structure, taking a single charging module with a power of 30kW as an example:

[0034] like Figure 1 The subsystem includes two power modules and two output ports. Each power module includes one or two charging modules, with a total adjustable power of 90kW.

[0035] When dispatching to output port S1:

[0036] If it is necessary to adjust the power from 0 to 30 kW, close the DC contactor KM1 to adjust the charging module M1;

[0037] If a power of 30~60kW is required, close DC contactor KM2 to adjust charging modules M2 and M3.

[0038] The same applies when configuring output port S2.

[0039] like Figure 2 The subsystem includes three power modules and three output ports. Each power module includes one, two, and three charging modules, respectively, with a total power of 180kW.

[0040] When dispatching to output port S1:

[0041] If a power of 0~30kW needs to be allocated, close the DC contactor KM2 to allocate the charging module M1;

[0042] If a power of 30kW~60kW needs to be allocated, close DC contactor KM7 to allocate charging modules M2 and M3;

[0043] If you need to adjust the power from 60kW to 90kW, close DC contactors KM2 and KM7 to adjust M1, M2 and M3, or close KM3 to adjust charging modules M4, M5 and M6.

[0044] If a power of 90kW~120kW needs to be allocated, close DC contactors KM2 and KM3 to allocate charging modules M1, M4, M5 and M6.

[0045] If a power of 120kW~150kW needs to be allocated, close DC contactors KM3 and KM7 to allocate charging modules M2, M3, M4, M5, and M6.

[0046] If a power of 150kW~180kW needs to be allocated, close DC contactors KM2, KM3, and KM7 to allocate charging modules M1, M2, M3, M4, M5, and M6.

[0047] The same principle applies when configuring output ports S2 and S3.

[0048] like Figure 3 The subsystem includes 3 power modules and 4 output ports. Each power module includes 1, 2, and 2 charging modules respectively, with a total adjustable power of 150kW.

[0049] like Figure 4 The subsystem includes four power modules and four output ports. Each power module includes one, two, two, or three charging modules, with a total adjustable power of 240kW.

[0050] like Figure 5The subsystem includes 4 power modules and 5 output ports. Each power module includes 1, 2, 2, and 3 charging modules respectively, with a total adjustable power of 240kW.

[0051] like Figure 6 The diagram shows the polygonal matrix charging scheduling circuit structure when the number of subsystems is 1. The number of charging loops is 12, denoted as C1 to C12. The subsystem includes 3 power modules and 3 output ports. Each power module includes 1, 2, and 3 charging modules, respectively, with a total power of 150kW.

[0052] The three output ports of this subsystem are connected to four charging circuits respectively, and their on / off states are controlled by DC contactors KM1-10~KM1-13, KM1-14~KM1-17, and KM1-18~KM1-21 respectively.

[0053] like Figure 7 The polygonal matrix charging scheduling circuit structure shown still has 12 charging loops and 3 subsystems, where all subsystems can be... Figure 6 The subsystems shown can also have 2, 4, or 6 output ports, etc.
