In this way, the problem that the load of the split-phase power supply unit 110 is large when the split-phase power supply unit is used for supplying power, so that the load of the whole multi-phase power supply module 100 is unbalanced is avoided, and the problem that the whole charging control system is overloaded is avoided. Referring to fig. 1, fig. 1 is a schematic structural diagram of a charging control system according to the present embodiment. As shown in fig. 1, the charging control system provided in this embodiment includes a detection control module 300, a multiphase power module 100, a power supply module 200, and a client module 400;
Each split-phase power supply unit 110 is connected with more than two power supply units 210; the detection control module 300 is electrically connected with the split-phase power supply unit 110, the power supply unit 210 and the client module 400, respectively;
the detection control module 300 is configured to detect an available power supply capacity of the split-phase power supply unit 110, and obtain, in real time, a power supply state of the split-phase power supply unit 110 according to the available power supply capacity, so as to obtain, after receiving a charging request signal for using the target power supply unit, a power supply state of a target split-phase power supply connected to the target power supply unit according to the charging request signal, and send, to the client module 400, target information of the target power supply state and power supply selection information of other split-phase power supplies in the multi-phase power supply module, where the power supply selection information and the power supply state of other split-phase power supply units in the multi-phase power supply module 100 are better than the power supply state of the target power supply state;

The multi-phase power module 100 is a power supply device that supplies power to a power supply unit by combining a plurality of single-phase power sources and adopting a multi-phase power supply mode. In the embodiment of the present application, the multiphase power module 100 is used for providing electric energy in the charging control system, that is, the multiphase power module 100 is electrically connected to the power supply module 200, and the multiphase power module 100 is used for providing electric energy to the power supply module 200.
In some embodiments, the multi-phase power module 100 may also be used for cell or mall power. In this embodiment of the present application, the multiphase power supply module 100 includes more than two split-phase power supply units 110, where the split-phase power supply units 110 are used to provide electric energy, the split-phase power supply units 110 may be one of the single-phase power supplies in the multiphase power supply module 100, and the single-phase power supply is used for single-phase power supply, where the single-phase power supply technology refers to a traction power supply mode of a neutral section of a line where the voltage phases of contact networks of different power substations are the same. For example, in the embodiment of the present application, the multiphase power module 100 may be a three-phase power source, where the three-phase power source uses a three-phase power supply to supply power, and the three-phase power source includes three split-phase power sources, where the multiphase power module 100 includes three single-phase power sources, and each single-phase power source may be a split-phase power source unit 110.
The power supply module 200 may be connected to the electric device so as to perform charging, that is, the multiphase power supply module 100 may charge the electric device through the power supply module 200, wherein the power supply module 200 may include more than two power supply units 210, so that each split-phase power supply unit 110 is connected to at least one power supply unit 210. In use, the power supply unit 210 can adjust the power supply output power for charging the electric equipment, so as to adjust the load of the split phase power supply unit 110, and at the same time, the charging speed of the electric equipment can be changed by adjusting the power supply output power for charging. In some embodiments, the power supply unit 210 may be a charging pile group, or may be other power supply devices.
The detection control module 300 may determine the available capacity of the split phase power supply unit 110 by detecting the power supply amount of the split phase power supply unit 110, and adjust the power supply output power of the power supply unit 210 connected to the split phase power supply unit 110 by determining the power supply state of the split phase power supply unit 110 according to the available capacity. In this embodiment, since the "power supply capacity=current×voltage", and the voltage change is generally small in the circuit of the charge control system, the used capacity in the split-phase power supply unit 110 may be determined by detecting the used current of the split-phase power supply unit 110, the available capacity in the split-phase power supply unit 110 may be determined according to the difference between the preset rated capacity and the used capacity, the available current in the split-phase power supply unit 110 may be determined according to the "power supply capacity=current×voltage", and after the available current is obtained, the power supply availability may be obtained according to the formula "available current amount/rated current amount×100% =power supply availability", and the power supply state of the split-phase power supply unit 110 may be determined based on the power supply availability.
For example, in the embodiment of the present application, the multiphase power supply module 100 is a three-phase power supply, and the multiphase power supply module 100 includes three split-phase power supply units 110, which are an a-phase power supply unit, a b-phase power supply unit, and a c-phase power supply unit, respectively, in order to determine the power supply availability of each of the three-phase power supply units 110, the rated currents of the a-phase power supply unit, the b-phase power supply unit, and the c-phase power supply unit may be obtained respectively, then the used currents of the a-phase power supply unit, the b-phase power supply unit, and the c-phase power supply unit may be detected by the current detection device, and the usable currents of the a-phase power supply unit, the b-phase power supply unit, and the c-phase power supply unit may be obtained according to "power supply capacity=current voltage" and "usable power supply capacity=rated power supply capacity—used power supply capacity", and the usable currents of the a-phase power supply unit, b-phase power supply unit, the b-phase power supply unit, and the c-phase power supply unit may be obtained according to the formulas:
the available current of the a-phase power supply unit/rated current of the a-phase power supply unit is 100% = power supply availability of the a-phase power supply unit;
the available current of the b-phase power supply unit/rated current of the b-phase power supply unit =100% = power supply availability of the b-phase power supply unit;
The available current of the c-phase power supply unit/rated current of the c-phase power supply unit =100% = power supply availability of the c-phase power supply unit;
the power supply availability of the a-phase power supply unit, the power supply availability of the b-phase power supply unit and the power supply availability of the c-phase power supply unit are obtained, and then the power supply state of each split-phase power supply unit 110 in the multi-phase power supply module is determined according to the power supply unit 210.
In the embodiment of the present application, the power supply states of the split-phase power supply unit 110 include a fast charge state, a slow charge state, and a delayed waiting charge state. The power supply state of the split-phase power supply unit 110 may be set according to the power supply availability, for example, in some embodiments, if the power supply availability is greater than the first threshold, the power supply state of the split-phase power supply unit 110 is a fast-charging state; if the power supply availability is between the first threshold and the second threshold, the power supply state of the split-phase power supply unit 110 is a slow charge state, wherein the first threshold is greater than the second threshold; if the power supply availability is less than the second threshold, the power supply state of the split-phase power supply unit 110 is a delayed waiting state of charge, where the first threshold and the second threshold may be manually set thresholds, for example, in some embodiments, the first threshold may be 30% and the second threshold may be 10%, that is, when the power supply availability of the split-phase power supply unit 110 is greater than 30%, the available power supply capacity of the split-phase power supply unit 110 is sufficient, and the split-phase power supply unit 110 may perform fast charging, and when the power supply availability of the split-phase power supply unit 110 is between 10% and 30%, the available power supply capacity is sufficient, and may perform slow charging; when the power supply availability of the split-phase power supply unit 110 is less than 10%, it indicates that the available power supply capacity of the split-phase power supply unit 110 is tense, and charging cannot be performed currently.
When the usage state of the split-phase power supply unit 110 is a fast charge state, the detection control module 300 may adjust the power supply output power of the power supply unit 210 connected to the split-phase power supply unit 110 to the first power supply output power according to the power supply state of the split-phase power supply unit 110; when the usage state of the split-phase power supply unit 110 is a slow charging state, the control unit 310 may adjust the power supply output power of the power supply unit 210 connected to the split-phase power supply unit 110 to the second power supply output power according to the power supply state of the split-phase power supply unit 110; when the usage state of the split-phase power supply unit 110 is a delayed waiting state of charge, the control unit 310 may adjust the power output power of the power supply unit 210 connected to the split-phase power supply unit 110 to zero or turn off the switch of the power supply unit 210 according to the power supply state of the split-phase power supply unit 110. Wherein the first power supply output power is greater than the second power supply output power.
The detection control module 300 may also be configured to receive a charging request signal sent by a user, where the charging request signal may be generated by the client module 400 in response to a charging request of the user, and the charging request signal may include information of a target power supply unit selected by the user from the plurality of power supply units 210 and information of a target split-phase power supply unit connected to the target power supply unit, where the detection control module 300 determines, according to the obtained power supply states of the respective split-phase power supply units 110, a target power supply state of the target split-phase power supply unit, and other split-phase power supply units in the multi-phase power supply module, where the power supply states are better than the target power supply state, and generates and sends, according to the power supply states of the other split-phase power supply units and the target power supply states, target information and preferred information to the client module 400.
In some embodiments, the power supply state being better than the target power supply state may refer to that if the target power supply state is a slow charge state, the power supply state of the other split-phase power supply units is a fast charge state, and if the target power supply state is a delayed waiting charge state, the power supply state of the other split-phase power supply units is a fast charge state or a slow charge state.
The client module 400 may be configured to interact with a user and be communicatively connected to the detection control module 300, where the client module 400 may, after receiving the target information and the preferred information, provide the target power supply unit of the user and other power supply units connected to other split-phase power supply units, so as to guide the user to make a charging selection for selecting the target split-phase power supply or other power supply units to charge.
Therefore, according to the power supply state of each split-phase power supply unit 110 in the multi-phase power supply module 100, when a user selects the charged power supply unit 210, the service condition of each power supply unit 210 can be displayed to the user through the client module 400, so that the user can conveniently select the power supply unit 210 connected with the split-phase power supply unit 110 with the better power supply state to charge, and the problem of power supply overload of the charging control system is avoided. Meanwhile, by determining the power supply output power of the power supply unit 210, the problem that the load of the split-phase power supply unit 110 is large when the split-phase power supply unit is in power supply use, so that the load of the whole multi-phase power supply module 100 is unbalanced can be avoided, and the problem that the whole charging control system is overloaded in power supply is avoided.
In order to better detect the usage of the split-phase-free power supply unit 110, as shown in fig. 2, in the embodiment of the present application, the detection control module 300 includes a control unit 310, a first detection unit 320, and a first multiphase power measurement and control unit 330;
the control unit 310 is electrically connected with the first multiphase power measurement and control unit 330 and the first detection unit 320 in turn, and the first detection unit 320 is also electrically connected with the split-phase power supply unit 110;
the first detecting unit 320 is configured to measure a first power supply amount of the split-phase power supply unit 110, and send a first power supply amount signal to the first multiphase power measurement and control unit 330 according to the first power supply amount;

Among other things, the control unit 310 may be a control unit 310 composed of one or more processors. In this embodiment, the processor may include one or more processing cores (e.g., a single core processor (S) or a multi-core processor (S)). By way of example only, the Processor may include a central processing unit (Central Processing Unit, CPU), an application specific integrated circuit (Application Specific Integrated Circuit, ASIC), a special instruction set Processor (Application Specific Instruction-set Processor, ASIP), a graphics processing unit (Graphics Processing Unit, GPU), a physical processing unit (Physics Processing Unit, PPU), a digital signal Processor (Digital Signal Processor, DSP), a field programmable gate array (Field Programmable Gate Array, FPGA), a programmable logic controller (Programmable Logic Controller, PLC), a microcontroller unit, a reduced instruction set computer (Reduced Instruction Set Computing, RISC), a microprocessor, or the like, or any combination thereof, the specific model of which is not limited.
The first detecting unit 320 is configured to detect a magnitude of a current output from the output terminal of the multiphase power module 100, and the first detecting unit 320 is configured to detect a magnitude of a current output from the output terminal of each split-phase power unit 110. When the first detecting unit 320 is configured to detect the total output current of the multiphase power module 100, the first detecting unit 320 may determine the magnitude of the current output by the output terminal of each of the split-phase power units 110 according to the usage time of each of the split-phase power units 110 in the multiphase power module 100 and the magnitude of the detected current.
In some embodiments, the first detecting unit 320 may determine the magnitude of the current output by the output terminal of the split-phase power supply unit 110 by detecting the magnitude of the voltage, for example, voltage detection may be performed by a resistance measurement method, a voltage sensor measurement method, or the like; the magnitude of the current output by the output end of each split-phase power supply unit 110 can also be directly detected, for example, the magnitude of the current output by the output end of each split-phase power supply unit 110 can be directly measured by a mutual inductance detection method, that is, in the circuit of the multi-phase power supply module 100, when the primary winding flows current with different magnitudes, the secondary winding induces corresponding voltages with different magnitudes. The current flowing through the main winding can be calculated by reading the voltage value of the mutual winding. After detecting the magnitude of the used current output from each of the split-phase power supply units 110, the first detecting unit 320 may convert the detected used current into a used current signal, and transmit the used current signal of each of the split-phase power supply units 110 to the control unit 310 of the detection control module 300.
For example, in some embodiments, the first detection unit 320 may be a current transformer, which may convert a primary side large current into a secondary side small current for measurement according to an electromagnetic induction principle.

For example, in the embodiment of the present application, the first multiphase power measurement and control unit 330 may be a three-phase power measurement and control device.
