[0045] Next, the technical solutions in the embodiments of the present application will be clearly and completely described with reference to the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments.

[0046] Figure 1 Structural schematic diagram of a charging device provided by an embodiment of the present application. As Figure 1 shown, the charging device 100 may include: a control module 110, a plurality of power modules 120, and a plurality of charging guns 130;

[0047] The plurality of power modules 120 are connected to the plurality of charging guns 130 through a switch array. The control end of each contactor in the switch array is also connected to the control module 110 to control the on and off of the switch array through the control module 110. At the same time, since the plurality of charging guns 130 are also communicatively connected to the control module 110, the control module 110 can also collect the plugging conditions of the plurality of charging guns 130. Each charging gun 130 can be used to connect to a vehicle, so that the charging device 100 can dynamically adjust the power output according to the charging requirements of different vehicles. Compared with the traditional charging device with fixed power distribution, the charging efficiency is significantly improved and the charging time is reduced. For example, for a vehicle that supports high-power fast charging, multiple power modules 120 can be quickly configured to be connected in parallel to meet its high-power requirements.

[0048] Among them, the control module is used to execute the power distribution method of the charging device. The switch array is composed of a plurality of contactors.

[0049] It should be noted that in Figure 1 , each charging gun 130 corresponds to a power module 120. For example, if charging gun 130-1 is used, the corresponding power module 120-1 must be in use, and the contactor 1 in the switch array must be in the closed state.

[0050] The charging device provided in the present application may be composed of a control module, multiple power modules and multiple charging guns; the multiple power modules are connected to multiple charging guns through a switch array, and the multiple charging guns are also connected to the control module for communication to obtain the plug-in status of the charging guns, and the switch array is also connected to the control module to control the on and off of the switch array. Among them, the control module is used to execute the power allocation method of the charging device. Therefore, the present application can dynamically adjust the power output according to the charging needs of different vehicles. Compared with the traditional charging equipment with fixed power allocation, it significantly improves the charging efficiency, reduces the charging time, and ensures the operational reliability of the charging equipment.

[0051] Optionally, the present application further provides a control module 110, Figure 2 This is a schematic diagram of the structure of a control module provided in an embodiment of the present application. Figure 2 As shown, the control module 110 may include: a processor 111 and a memory 112 .

[0052] The memory 112 stores machine executable instructions that can be executed by the processor 111, that is, when the control module 110 is running, the machine readable instructions are executed, and the processor 111 communicates with the memory 112 via a bus. The processor 111 can execute the machine executable instructions to implement the power distribution method of the charging device.

[0053] Among them, the memory 112, the processor 111 and the bus elements are directly or indirectly electrically connected to each other to realize data transmission or interaction. For example, these elements can be electrically connected to each other through one or more communication buses or signal lines. The mobile storage device includes at least one software function module that can be stored in the memory 112 in the form of software or firmware or solidified in the operating system (OS) of the electronic device. The processor 111 is used to execute the executable modules stored in the memory 112, such as the software function modules and computer programs included in the power distribution method of the charging device of the mobile storage medium.

[0054] Among them, the memory 112 can be, but is not limited to, random access memory (Random Access Memory, RAM), read only memory (Read Only Memory, ROM), programmable read-only memory (Programmable Read-Only Memory, PROM), erasable programmable read-only memory (Erasable Programmable Read-Only Memory, EPROM), electrically erasable read-only memory (Electric Erasable Programmable Read-Only Memory, EEPROM), etc.

[0055] The power distribution method of the charging device provided by the embodiment of the present application may be executed by the processor in the control module 110. The following further explains the power distribution method of the charging device provided by the embodiment of the present application. Figure 3 It is a schematic flow chart of a power distribution method of a charging device provided by an embodiment of the present application. Figure 1 As Figure 3 shown, the method may include:

[0056] S201. If it is detected that the target charging gun on the charging device is connected to the target vehicle, obtain the real-time charging demand parameters of the target vehicle.

[0057] In a possible implementation manner, if the control device detects that the target charging gun is in the plugged state, it means that the target charging gun is connected to the target vehicle. Then, the real-time charging demand parameters of the target vehicle can be transmitted to the control module through CAN (Controller Area Network, a communication bus protocol) communication, so that the control module obtains the real-time charging demand parameters of the target vehicle. Among them, the real-time charging demand parameters are, for example, the demand voltage parameter and / or the demand current parameter, the real-time battery power, the current time, and the scheduled charging time.

[0058] S202. According to the real-time charging demand parameters, determine the target power module that meets the constraint conditions of the real-time charging demand parameters from multiple power modules of the charging device.

[0059] In a possible implementation manner, based on the obtained real-time charging demand parameters, the control module can screen out the target power module that meets the constraint conditions of the real-time charging demand parameters from multiple power modules of the charging device.

[0060] Among them, the constraint conditions of the real-time charging demand parameters can be understood as: based on the preset rated parameters of multiple power modules, perform compliance verification on the real-time charging demand parameters to clarify whether the two match.

[0061] S203. Control the power line between the target power module and the target charging gun to conduct, so that the target power module charges the target vehicle through the target charging gun.

[0062] In a possible implementation manner, after determining the target power module, control the power line between the target power module and the target charging gun to conduct, that is, control the contactor between the target power module and the target charging gun to close, so that the target power module can charge the target vehicle through the target charging gun.

[0063] The present application provides a power distribution method for a charging device. If it is detected that a target charging gun on the charging device is connected to a target vehicle, the real-time charging demand parameters of the target vehicle are obtained, so as to provide an accurate data basis for subsequent power distribution by obtaining the real-time charging demand parameters, enabling the charging device to understand the personalized charging needs of the target vehicle, which is a prerequisite for achieving efficient charging; according to the real-time charging demand parameters, a target power module that meets the constraint conditions of the real-time charging demand parameters is determined from multiple power modules of the charging device, so as to avoid slow charging caused by insufficient power modules and prevent energy waste and loss of the charging device caused by excessive power modules through this precise matching, improving the charging efficiency and shortening the charging duration of the target vehicle; controlling the power line of the target power module and the target charging gun to be conducted, so that the target power module charges the target vehicle through the target charging gun, thereby ensuring that the target vehicle obtains continuous and stable power supply during the charging process, avoiding problems such as charging interruption and battery damage caused by power fluctuations, ensuring the safety of the charging process and the service life of the vehicle battery, improving the charging quality, and thus enhancing the user's satisfaction and usage experience with the charging device.

[0064] Optionally, the above real-time charging demand parameters may include: demand voltage parameters and / or demand current parameters. Since the demand voltage parameters and demand current parameters can directly determine the power required during vehicle charging, when these two parameters are clearly known, the demand power parameters of the target vehicle can be known.

[0065] In a possible implementation embodiment, in the above method, determining a target power module that meets the constraint conditions of the real-time charging demand parameters from multiple power modules of the charging device according to the real-time charging demand parameters may include:

[0066] Determining a target power module from multiple power modules according to the demand voltage parameters and / or demand current parameters.

[0067] In a possible implementation manner, during the charging process of the target vehicle, the demand voltage parameters and / or demand current parameters of the target vehicle can be compared with the preset rated voltage parameters and / or preset rated current parameters of multiple power modules in the charging device to screen out a target power module that meets the charging needs of the target vehicle. For example, for a vehicle with high demand voltage and large current, a power module with relatively higher preset rated parameters is selected to supply power to it, avoiding slow charging speed caused by insufficient power, greatly improving the charging efficiency, shortening the charging duration of the vehicle, and improving the service efficiency of the charging device.

[0068] It should be noted that when the required current parameter is known, during the charging process of the target vehicle, once it is detected that the charging amount of the target vehicle reaches the preset power (such as 80% power), the control module can adjust and optimize the charging process of the subsequent remaining power (such as 20% power) of the target vehicle to ensure the safety, efficiency of charging and the service life of the battery.

[0069] Because during the charging process of the vehicle, the charging current is usually dynamically adjusted according to the battery power state of the target vehicle to ensure the safety and efficiency of charging and extend the service life of the target vehicle battery. Specifically, when the battery power is low, the charging device can use a larger current for fast charging to quickly restore the electrical energy of the battery. However, when the battery power is close to full (such as reaching 80% power), continuing to charge with a large current may cause the battery to overheat and overcharge, thus affecting the performance and life of the battery and even posing a safety hazard. Therefore, in the later stage of charging, the charging device usually automatically adjusts the charging current to a trickle. This trickle charging is a small-current charging method that can continue to charge at a slower speed when the battery is close to full charge, ensuring that the battery is fully charged while avoiding overcharging. This approach helps maintain the health of the battery, reduce the aging rate of the battery, and ultimately improve the overall service life of the battery.

[0070] For the power distribution method of the charging device provided in this application, the real-time charging demand parameter can be composed of a demand voltage parameter and / or a demand current parameter; according to the demand voltage parameter and / or the demand current parameter, a target power module is determined from multiple power modules. Thus, this application screens power modules based on the demand voltage parameter and the demand current parameter, and can make full use of the resources of multiple power modules in the charging device. In the case of multiple vehicles charging simultaneously, different power modules can be reasonably allocated according to the specific demand voltage parameter and / or demand current parameter of each vehicle, avoiding the idle or unreasonable use of power modules, realizing the maximization of the utilization of power module resources, and improving the overall utilization rate of the charging device.

[0071] Optionally, the above real-time charging demand parameter may further include: real-time battery power and the current time.

[0072] Figure 4 Flow schematic of a power distribution method for a charging device provided by an embodiment of this application Figure 2 As Figure 4 shown, in the above method, determining a target power module from multiple power modules according to the demand voltage parameter and the demand current parameter may include:

[0073] S301. Determine the power modules that are idle at the current time from multiple power modules as candidate power modules according to the real-time battery power and the current time.

[0074] In a possible implementation, based on the real-time battery power, the urgent charging requirements of the target vehicle can be accurately judged. For example, for a vehicle with extremely low power, an adaptation unit is preferentially selected from the idle power modules to avoid range anxiety caused by waiting for other vehicles to complete charging and ensure the basic driving requirements of the vehicle.

[0075] Based on the current time, the charging device can flexibly adjust the strategy according to peak and off-peak periods of electricity consumption. During the off-peak period at night, even if the vehicle battery power is not low, the idle power modules can be fully utilized for slow charging, which can not only balance the power grid load but also extend the battery life; while during the peak period during the day, power is preferentially allocated to the vehicles in urgent need of charging.

[0076] S302. Determine the target power module from the candidate power modules according to the required voltage parameter and / or required current parameter.

[0077] In a possible implementation, by real-time monitoring of the current time and the usage status of the power modules, the charging potential of the charging device can be fully exploited. During the off-peak period, even if only a small number of vehicles are charging, the power modules can be allocated as needed to avoid energy consumption waste caused by multiple modules running simultaneously. For example, when only one vehicle is charging, only a single or a few power modules that meet its requirements are enabled, while the other modules are placed in the standby state to reduce the overall energy consumption of the device.

[0078] For the power distribution method of the charging device provided in this application, the real-time charging requirement parameter can also be composed of the real-time battery power and the current time; according to the real-time battery power and the current time, the power modules that are idle at the current time are determined from multiple power modules as candidate power modules; the target power module is determined from the candidate power modules according to the required voltage parameter and / or required current parameter. Thus, this application determines the target power module from the candidate power modules according to the real-time battery power and the current charging time, realizes the refined management of the idle power module resources, reduces the idle time of the power modules, and keeps the charging device resources in an efficient circulation state all the time. Compared with the traditional fixed distribution mode, the overall utilization rate of the charging device is significantly improved.

[0079] Figure 5 It is a flowchart of a power distribution method for a charging device provided by an embodiment of this application Figure 3 As Figure 5 shown, in the above method, determining the power modules that are idle at the current time from multiple power modules as candidate power modules according to the real-time battery power and the current time may include:

[0080] S401. Determine the current charging period in which the current time is located according to the current time.

[0081] In a possible implementation manner, different current charging periods are divided according to the current time. For example, the current charging period can be determined based on what power consumption time the current time is in (such as peak power consumption period, off-peak power consumption period, flat peak period), or it can also be determined based on whether the current time is a holiday (including weekends) or a weekday time.

[0082] S402. Determine the required charging power corresponding to the target vehicle according to the real-time battery power and the current charging period.

[0083] In a possible implementation manner, according to the current charging period and in combination with the real-time battery power, the control module can accurately calculate the charging power required by the target vehicle at different times. For example, when the current charging period is the off-peak power consumption period, for a vehicle with a low battery level, the charging power can be appropriately increased to speed up the charging speed; while during the peak power consumption period, to avoid causing too much pressure on the power grid, the charging power is reduced and the charging time is extended. While ensuring the completion of charging, the power grid load is reasonably balanced and the overall charging efficiency is improved.

[0084] S403. Determine the candidate power module from multiple power modules of the charging device according to the required charging power and the current time.

[0085] In a possible implementation manner, determining the candidate power module from multiple power modules of the charging device according to the required charging power and the current time, that is, by determining the candidate power module in a time-sharing manner, can effectively balance the workload of each power module of the charging device. Avoiding some power modules being in a high-load operation state for a long time while some other power modules are idle, thus extending the service life of the power modules.

[0086] Exemplarily, if the current charging period is a weekday time and a holiday time period, for the charging device area preset in the highway service area, the number of people using the charging device to charge is small during the weekday time period, and the number of people using the charging device to charge is large during the holiday time period. High-power charging can be used during weekdays. For example, if the battery of the target vehicle is 80 degrees, multiple power modules can be used to output a power of 240 kW through the charging gun 1 to charge the target vehicle, and the full charge time is about 33.4 minutes. But during holidays, the target vehicle can be charged at full speed first. For example, if the battery of the target vehicle is 80 degrees, 64 degrees of battery is charged to 80% of the full charge. 480 kW can be used to charge to 80% of the power in 13.3 minutes, and then 60 kW is used to charge for 26.7 minutes to full charge.

[0087] The power distribution method of the charging device provided by this application determines the current charging period in which the current time is located according to the current time. Since the power supply capacity of the power grid and the usage of the charging device are different in different periods, confirming the current charging period enables the charging device to adjust the power distribution strategy in real time. Then, according to the real-time battery power and the current charging period, the required charging power corresponding to the target vehicle is determined, and according to the required charging power and the current time, candidate power modules are determined from multiple power modules of the charging device, so as to supply power to the vehicle by reasonably combining multiple power modules, giving full play to the potential of the charging device and maximizing the utilization of the power module resources of the charging device. At the same time, the overall stability and reliability of the charging device are improved, and the maintenance cost of the charging device is reduced.

[0088] Optionally, the above real-time charging demand parameter may further include: the reserved charging time. Users can freely select a suitable reserved charging time according to their travel plans and the power consumption of the power grid. For example, if the user expects that the electricity price is lower during the low-peak period of the power grid at night, they can make a reservation in advance to charge the vehicle during this period, which not only saves the charging cost but also eliminates the need to wait at the charging site, greatly improving the flexibility and convenience of charging.

[0089] In a possible implementation embodiment, in the above method, determining the power modules that are idle at the current time as candidate power modules from multiple power modules according to the real-time battery power and the current time may include:

[0090] If the current time reaches the reserved charging time, then determine the power modules that are idle at the current time as candidate power modules from multiple power modules according to the real-time battery power and the current time.

[0091] In a possible implementation manner, if the current time reaches the reserved charging time, the charging device can quickly determine the power modules that are idle at the current time from multiple power modules according to the real-time battery power of the target vehicle and the current time, set the power modules in the idle state as candidate power modules, and charge the target vehicle according to the candidate power modules.

[0092] The power distribution method of the charging device provided by this application may also be composed of the reserved charging time for the real-time charging demand parameter; if the current time reaches the reserved charging time, then determine the power modules that are idle at the current time as candidate power modules from multiple power modules according to the real-time battery power and the current time, so as to start charging the vehicle through the candidate power modules, avoiding the situation that the user still needs to wait for an idle power module after arriving at the charging station, effectively reducing the waiting time of the user and improving the charging efficiency.

[0093] In a possible implementation embodiment, in the above method, determining a target power module that meets the constraint conditions of the real-time charging demand parameters from multiple power modules of the charging device may include:

[0094] Determining a target power module from multiple power modules according to the real-time charging demand parameters and the historical charging parameters of each power module on the charging device.

[0095] In a possible implementation manner, the real-time charging demand parameters can reflect the specific charging demand of the current vehicle, and the historical charging parameters record the performance of each power module during previous charging processes. By comprehensively considering these two factors, the charging device can more accurately match the most suitable power module for the target vehicle. For example, some power modules show characteristics of fast charging speed and high stability when charging vehicles with specific voltage and current requirements. When encountering vehicles with similar real-time charging demands, these modules can be preferentially selected, thus significantly improving the charging efficiency and reducing the charging time.

[0096] The power allocation method of the charging device provided in this application determines a target power module from multiple power modules according to the real-time charging demand parameters and the historical charging parameters of each power module on the charging device. Thus, since the real-time charging demands of different vehicles may vary greatly, and the historical charging parameters of each power module can reflect their adaptability to different demands. By combining the real-time charging demand parameters and the historical charging parameters, the charging device of this application can better handle various complex charging scenarios and provide more suitable charging solutions for different types of vehicles. Whether it is the fast charging demand of high voltage and large current or the ordinary charging demand of low voltage and small current, the most suitable power module can be found to meet the requirements, improving the versatility and compatibility of the charging device.

[0097] In a possible implementation embodiment, in the above method, determining a target power module from multiple power modules according to the real-time charging demand parameters and the historical charging parameters of each power module on the charging device may include:

[0098] Determining a target power module from multiple power modules according to the real-time charging demand parameters and the historical charging parameters of each power module on the charging device by using a preset machine learning model.

[0099] Among them, the preset machine learning model can be selected according to the actual situation.

[0100] In a possible implementation, the preset machine learning model can comprehensively understand the usage frequency and performance status of each power module on the charging device by learning the historical charging parameters of each power module. Combining with the real-time charging demand parameters, when allocating power modules, it can automatically balance the loads of each module, avoiding overuse of some power modules while other power modules are idle. In this way, it can not only give full play to the efficiency of each power module, but also extend the overall service life of the device and reduce the operation cost.

[0101] Meanwhile, based on the historical charging parameters of the power module, the preset machine learning model can establish a fault prediction model. By continuously monitoring the real-time status of the module, the preset machine learning model can predict possible faults in advance and adjust the allocation of power modules in a timely manner to avoid faults during the charging process and improve the reliability and stability of the charging device.

[0102] The power allocation method of the charging device provided by this application determines the target power module from multiple power modules by using a preset machine learning model according to the real-time charging demand parameters and the historical charging parameters of each power module on the charging device. Thus, this application realizes an automated power module allocation decision through the machine learning model without manual intervention. This not only improves the speed and accuracy of the decision-making, but also reduces the cost and error of manual operation. The charging device can automatically complete the allocation of power modules according to real-time data, improving the user experience.

[0103] In a possible implementation example, in the above method, determining the target power module that meets the constraint conditions of the real-time charging demand parameters from multiple power modules of the charging device according to the real-time charging demand parameters may include:

[0104] Determine the target power module from multiple power modules according to the real-time charging demand parameters and the rated charging parameters of each power module on the charging device.

[0105] In a possible implementation, the real-time charging demand parameters can reflect the current specific charging requirements of the device to be charged, such as voltage, current, power, etc. The rated charging parameters of the power module specify the range of charging capabilities that each power module can provide. By comparing these two sets of parameters, the power module that can meet the real-time charging demand can be accurately found, ensuring that the charging power is precisely matched with the charging device requirements and avoiding problems such as too slow charging speed or device damage caused by power mismatch.

[0106] The power allocation method of the charging device provided by this application determines the target power module from multiple power modules according to the voltage and current requirements in the real-time charging demand parameters, combined with the rated charging parameters of each power module on the charging device, that is, the power module with the output voltage and current matching the device requirements can be selected to ensure the stability and safety of the charging process.

[0107] Figure 6 Flow schematic of a power distribution method for a charging device provided by an embodiment of the present application Figure 4 As Figure 6 shown, in the above method, determining a target power module from multiple power modules according to real-time charging demand parameters and the rated charging parameters of each power module on the charging device may include:

[0108] S501. Compare the real-time charging demand parameters and the rated charging parameters of each power module respectively.

[0109] S502. According to the comparison result, determine the power module whose rated charging parameter is greater than or equal to the real-time charging demand parameter as the target power module from multiple power modules.

[0110] In a possible implementation manner, by comparing the real-time charging demand parameters and the rated charging parameters of each power module, select the power module corresponding to the rated charging parameter greater than or equal to the real-time charging demand parameter, so as to avoid the power module bearing a load exceeding its bearing capacity during the charging process. This can prevent the power module from overheating, shortening its service life or even being damaged due to overload, and at the same time protects the charging device from being damaged by overload current or voltage, reducing the risk of safety accidents caused by charging overload.

[0111] It should be noted that if the rated charging parameters of each power module of the charging device in the present application are the same, the number of power modules can be determined according to the real-time charging demand parameters, and then according to the number of power modules, determine the sum of the rated charging parameters corresponding to the number of power modules from multiple power modules. At this time, it is necessary to ensure that the sum of the rated charging parameters is greater than or equal to the real-time charging demand parameter, and then determine the confirmed multiple power modules as the target power modules.

[0112] In addition, it should also be noted that since the rated charging parameters of each power module are the same, assuming that the rated power parameter of the power module is 60KW and the real-time demand power parameter of the target vehicle is 130KW, then it is confirmed that 3 power modules are required. However, to avoid energy waste of the third power module, 2 power modules will be allocated to the target vehicle, and the power module corresponding to the charging gun connected to the target vehicle and the remaining idle power modules will be connected in parallel to set the power module corresponding to the charging gun and the idle power module as the target power modules to charge the target vehicle.

[0113] The power distribution method of the charging device provided by the present application compares the real-time charging demand parameters and the rated charging parameters of each power module respectively; according to the comparison result, the power module whose rated charging parameter is greater than or equal to the real-time charging demand parameter is determined from multiple power modules as the target power module. Thus, the present application selects the power module whose rated charging parameter is greater than or equal to the real-time charging demand parameter, which can ensure that the power module has sufficient ability to provide the required power for the charging device. This can avoid the situation of too slow charging speed due to insufficient power, enable the charging device to charge at a relatively fast speed, improve the charging efficiency, and reduce the user waiting time. At the same time, when the rated parameter of the power module matches the real-time charging demand or has a certain margin, the power module can operate in an ideal working state. This helps to optimize the energy conversion efficiency during the charging process, reduce energy loss, improve the overall efficiency of the charging device, and make the charging process more efficient and energy-saving.

[0114] To facilitate the understanding of the above power distribution method of the charging device, the embodiment of the present application also provides an example of the flow of a power distribution method of a charging device, which will be further described below in conjunction with the drawings. Figure 7 Schematic diagram of the flow of a power distribution method of a charging device provided by an embodiment of the present application Figure 5 . As Figure 7 shown, the schematic diagram provided by the embodiment of the present application Figure 5 may include:

[0115] S601. Obtain the real-time charging demand parameters of the target vehicle.

[0116] Among them, the real-time charging demand parameters may include: demand voltage parameter and / or demand current parameter, real-time battery power, current time, scheduled charging time, demand power parameter, etc. There is no limitation here.

[0117] Specifically, if it is detected that the target charging gun on the charging device is connected to the target vehicle, the real-time charging demand parameters of the target vehicle are transmitted to the control module through CAN communication, so that the control module obtains the real-time charging demand parameters of the target vehicle.

[0118] S602. According to the real-time charging demand parameters, determine the target power module that meets the constraint conditions of the real-time charging demand parameters from multiple power modules of the charging device, and control the power line of the target power module to be conducted with the target charging gun, so that the target power module charges the target vehicle through the target charging gun.

[0119] Specifically, according to the real-time charging demand parameters, for example, the demand power parameter, if the demand power parameter is 80KW, the control module performs the following operations:

[0120] First, locate the charging gun connected to the target vehicle (assumed to be charging gun 1), and determine the power module 1 corresponding to this charging gun 1 as the basic target power module. Then, based on the rated power parameter of a single power module being 60 KW, it is calculated that one additional power module needs to be allocated additionally under the current required power parameter to meet the power requirement of 80 KW. Next, the control module can detect the usage status of available power modules one by one according to the preset power module sorting. If power module 2 is in an idle state, then control the closing of contactor 1, contactor 10, and contactor 2, and connect power module 1 and power module 2 in parallel to supply power to charging gun 1 through the combined output power of 120 KW to meet the charging requirement of the target vehicle. If power module 2 is in a borrowed state, automatically detect its expected return time. If it meets the charging time requirement of the target vehicle, then perform the parallel operation after its return; if power module 2 is charging the first vehicle connected to charging gun 2, then skip power module 2 and continue to detect the usage status of power module 3. If power module 3 is in an idle state, immediately close contactor 1, contactor 10, contactor 17, and contactor 3 to connect power module 1 and power module 3 in parallel to form a 120 KW output circuit to supply power to the target vehicle. Subsequent module detection: If power module 3 is also in a borrowed state, then continue to detect subsequent power modules (such as power module 4, power module 5, etc.) in the order of power module sorting until an available (idle state) power module is found and combined in parallel with power module 1 to charge the target vehicle.

[0121] It should be noted that the above power distribution is only an example and should not be construed as a limitation to this application.

[0122] The power distribution method of the charging device provided by this application obtains the real-time charging demand parameters of the target vehicle. According to the real-time charging demand parameters, it determines the target power module that meets the constraint conditions of the real-time charging demand parameters from multiple power modules of the charging device, and controls the power line between the target power module and the target charging gun to conduct, so that the target power module charges the target vehicle through the target charging gun. It can be seen that for the power distribution method of the charging device of this application, the entire allocation process follows the principle of giving priority to idle modules with priority and dynamic resource scheduling. By real-time monitoring the usage status and return time of power modules, it can efficiently meet the new charging demand on the premise of ensuring that the existing charging tasks are not interrupted, avoiding waste of power resources and ensuring the stability of power supply when multiple vehicles charge simultaneously.
