Description

Technical Field

[0001] The embodiments of the present application relate to the field of charging devices, and in particular to a charging device, a charging control method, and a computing device. Background Art

[0002] A charging stack is a centralized charging device that can achieve dynamic power distribution to multiple charging objects by integrating multiple charging modules and multiple charging guns.

[0003] In related technologies, charging equipment can achieve charging power distribution through a matrix topology. Matrix topology arranges charging modules in a matrix, interconnecting each module in rows and columns, and controlling the connection relationship through relays to achieve power distribution.

[0007] In a charging device provided by an embodiment of the present application, any charging gun can be connected to multiple charging modules. When the power of the first charging module cannot meet the required power of the charging gun, the connection between the second, third, and fourth charging modules can provide sufficient power to the charging gun. Furthermore, compared to an embodiment in which a corresponding switching circuit is provided between the charging gun and each charging module, the number of switching circuits is reduced, which reduces the number of failure points of the charging device, thereby improving the stability of the charging device.

[0008] In one possible implementation,

[0009] The charging gun is connected to the first charging module via a first line;

[0010] The charging gun is connected to the second charging module through the switch circuit corresponding to the second charging module and the first circuit.

[0011] In the above method, the first charging module and the second charging module are connected to the charging gun through the first line, so that the first charging module and the second charging module can both supply power to the charging gun, thereby improving the efficiency of the charging device.

[0012] In one possible implementation, the charging gun is connected to one end of the first line;

[0013] The other end of the first circuit is connected to one end of the switch circuit corresponding to the first charging module and the second charging module respectively;

[0014] The other end of the switch circuit corresponding to the second charging module is connected to the second charging module.

[0015] In the above method, the number of switch circuits can be reduced, the failure points of the charging device are reduced, and the stability of the charging device is improved.

[0016] In one possible implementation, the charging gun is connected to the third charging module via the second line and a switch circuit corresponding to the third charging module;

[0017] The charging gun is connected to the fourth charging module through the second line, the switch circuit corresponding to the third charging module, and the switch circuit corresponding to the fourth charging module.

[0018] In the above method, the third charging module and the fourth charging module can be connected to the charging gun through the second line, so that the third charging module and the fourth charging module can both supply power to the charging gun, thereby improving the efficiency of the charging device.

[0019] In one possible implementation, the charging gun is connected to one end of the switch circuit corresponding to the third charging module, and the other end of the switch circuit corresponding to the third charging module is connected to one end of the second circuit;

[0020] The other end of the second circuit is connected to one end of the switch circuit corresponding to the third charging module and the fourth charging module respectively, and the other end of the switch circuit corresponding to the fourth charging module is connected to the fourth charging module.

[0021] In the above method, the number of switch circuits can be reduced, the failure points of the charging device are reduced, and the stability of the charging device is improved.

[0022] In a possible implementation, the number of the plurality of charging modules and the number of the plurality of charging guns are M, where M is an integer greater than 1, wherein:

[0023] The first charging module corresponding to the i-th charging gun is the i-th charging module among the multiple charging modules, where i is a positive integer less than or equal to M.

[0024] In the above method, the first charging module corresponding to the charging gun can be uniquely determined, thereby improving the stability of the charging device.

[0025] In a possible implementation, the number of the plurality of charging modules and the number of the plurality of charging guns are M, respectively, where M is an even number greater than 1;

[0026] The number of the first charging module corresponding to the charging gun is 1;

[0027] The number of second charging modules corresponding to the charging gun is

[0028] The number of the third charging module corresponding to the charging gun is 1;

[0029] The number of the fourth charging modules corresponding to the charging gun is

[0030] Each second charging module is connected via a switch circuit corresponding to the second charging module;

[0031] Each fourth charging module is connected via a switch circuit corresponding to the fourth charging module;

[0032] The adjacent second charging module and fourth charging module are connected via a switch circuit corresponding to the fourth charging module.

[0033] In the above method, the number of the first charging module, the second charging module, the third charging module and the fourth charging module corresponding to the charging gun can be determined, thereby improving the stability of the charging device.

[0034] In a second aspect, an embodiment of the present application provides a charging control method, comprising: obtaining a charging request corresponding to a charging gun, the charging request including a target charging power corresponding to the charging gun;

[0035] Determine a first charging power of a first charging module corresponding to the charging gun;

[0036] When the first charging power is greater than or equal to the target charging power, controlling the first charging module to charge the target object through the charging gun;

[0037] When the first charging power is less than the target charging power, the target charging module is determined among multiple charging modules based on the first charging power, the target charging power, the working status of each charging module in the charging device, and the priority between the charging modules, and the first charging module and the target charging module are controlled to charge the target object through the charging gun, and the working status is occupied or idle.

[0038] In an embodiment of the present application, a charging control method is provided. When power is required for a device to be charged via a charging gun, a charging request corresponding to the charging gun can be first obtained to determine the target charging power required by the charging gun; a first charging power of a first charging module corresponding to the charging gun can be determined; a determination can be made as to whether the first charging power is greater than or equal to the target charging power. If the first charging power is greater than or equal to the target charging power, the first charging module can be controlled to charge the target object via the charging gun; if the first charging power is less than the target charging power, a target charging module can be determined from multiple charging modules based on the first charging power, the target charging power, the operating status of each charging module in the charging device, and the priority between the charging modules. The first charging module and the target charging module can then be controlled to charge the target object via the charging gun. Thus, compared to a method of supplying power only through the charging module corresponding to the charging gun, in this solution, when the first charging module corresponding to the charging gun does not meet the target charging power, the charging gun can be powered by the second, third, and / or fourth charging modules corresponding to the charging gun according to the priority order, thereby improving the efficiency and stability of the charging device.

[0039] In one possible implementation, the priority of the second charging module corresponding to the charging gun is greater than the priority of the third charging module corresponding to the charging gun;

[0040] The priority of the third charging module corresponding to the charging gun is greater than the priority of the fourth charging module corresponding to the charging gun.

[0041] In the above method, the efficiency of charging control is improved by setting priorities.

[0042] In one possible implementation, the number of second charging modules corresponding to the charging gun is multiple; determining a target charging module from the multiple charging modules based on the first charging power, the target charging power, the operating status of each charging module in the charging device, and the priority between the charging modules includes:

[0043] determining a difference between the target charging power and the first charging power as a first remaining power;

[0044] Determine the working status of each second charging module corresponding to the charging gun;

[0045] If there are idle second charging modules among the plurality of second charging modules corresponding to the charging gun, determine a target charging module among the idle second charging modules according to the first remaining power and the charging power of each idle second charging module;

[0046] When there is no idle second charging module among the multiple second charging modules corresponding to the charging gun, a target charging module is determined from the third charging module and / or the fourth charging module corresponding to the charging gun according to the first residual power.

[0047] In the above method, when the first charging power cannot reach the target charging power, the target charging module that supplies power to the charging gun is determined by the first remaining power, thereby ensuring that the charging gun can provide the target charging power for the device to be charged, thereby improving the efficiency of the charging device.

[0048] In one possible implementation, determining a target charging module among the second charging modules in the idle state according to the first remaining power and the charging power of each second charging module in the idle state includes:

[0049] Determine the sum of the charging powers of the second charging modules in the idle state as the second charging power;

[0050] If the second charging power is less than the first remaining power, the idle second charging modules are determined as part of the target charging modules. Another part of the target charging modules is determined from the third charging modules and / or fourth charging modules corresponding to the charging gun based on the first remaining power and the second charging power.

[0051] If the second charging power is greater than or equal to the first residual power, a target charging module is determined from the idle second charging modules according to the total output power and the total charging time of each idle second charging module.

[0052] In the above method, if there is an idle second charging module, a target charging module is determined among the second charging modules, thereby improving the efficiency of the charging device.

[0053] In a possible implementation, a target charging module is determined from among the idle second charging modules according to the total output power and the total charging time of each idle second charging module, including:

[0054] When the number of idle second charging modules is equal to 1, determining the idle second charging module as a target charging module;

[0055] When the number of idle second charging modules is greater than 1 and the number of idle second charging modules is N, the usage rates corresponding to the N second charging modules are determined in sequence according to the total output power and the total charging time;

[0056] A target charging module is determined from idle second charging modules according to the usage rates and the first remaining powers corresponding to the N second charging modules.

[0057] In the above method, when the number of second charging modules in the idle state is equal to 1, the second charging module can meet the first residual power, that is, it can meet the target charging power of the charging gun; when the number of second charging modules in the idle state is greater than 1, according to the utilization rate of the charging module, when the power is met, the second charging module with low utilization rate is preferentially selected for power supply, thereby improving the power balance of the charging equipment.

[0058] In one possible implementation, determining another portion of target charging modules in the third charging module and / or the fourth charging module corresponding to the charging gun according to the first remaining power and the second charging power includes:

[0059] determining a difference between the first remaining power and the second charging power as the second remaining power;

[0060] Determine the working status of each third charging module corresponding to the charging gun;

[0061] If there are idle third charging modules among the multiple third charging modules corresponding to the charging gun, determine a target charging module among the idle third charging modules according to the second residual power and the charging power of each idle third charging module;

[0062] When there is no idle third charging module among the plurality of third charging modules corresponding to the charging gun, a target charging module is determined among the fourth charging modules corresponding to the charging gun according to the second residual power.

[0063] In the above method, when the power provided by the second charging module still does not meet the target charging power, the third charging module and / or the fourth charging module may be used to power the charging gun.

[0064] In one possible implementation, the method further includes obtaining a current charging power reached by the charging gun;

[0065] When the current charging power is greater than or equal to the preset charging power, the power supply to the charging gun is stopped in the reverse order of the priorities among the target charging modules.

[0066] In the above method, when the preset charging power is reached, in order to protect the health of the battery of the device to be charged, the power supply is gradually withdrawn in the reverse order of priority, thereby improving the stability of the charging device and the stability of the battery of the device to be charged.

[0067] In a third aspect, an embodiment of the present application provides a charging control device, comprising: an acquisition module, a determination module, a first control module, and a second control module, wherein:

[0072] In an embodiment of the present application, a charging control device is provided. When power is required to be supplied to a device to be charged via a charging gun, a charging request corresponding to the charging gun can be first obtained to determine the target charging power required by the charging gun; a first charging power of a first charging module corresponding to the charging gun can be determined; a determination can be made as to whether the first charging power is greater than or equal to the target charging power. If the first charging power is greater than or equal to the target charging power, the first charging module can be controlled to charge the target object via the charging gun; and if the first charging power is less than the target charging power, a target charging module can be determined from a plurality of charging modules based on the first charging power, the target charging power, the operating status of each charging module in the charging device, and the priority between the charging modules. The first charging module and the target charging module can then be controlled to charge the target object via the charging gun. Thus, compared to a method of supplying power only through the charging module corresponding to the charging gun, in this solution, when the first charging module corresponding to the charging gun does not meet the target charging power, the charging gun can be powered by the second, third, and / or fourth charging modules corresponding to the charging gun according to the priority order, thereby improving the efficiency and stability of the charging device.

Another part of the target charging modules is determined from the third charging modules and / or fourth charging modules corresponding to the charging gun based on the first remaining power and the second charging power.

[0085] If the second charging power is greater than or equal to the first residual power, a target charging module is determined from the idle second charging modules according to the total output power and the total charging time of each idle second charging module.

[0086] In the above method, if there is an idle second charging module, a target charging module is determined among the second charging modules, thereby improving the efficiency of the charging device.

[0210] The charging device 20 of the embodiment of the present application includes: multiple charging modules 21 and multiple charging guns 22, and the multiple charging modules 21 include: a first charging module 211, a second charging module 212, a third charging module 213 and a fourth charging module 214 corresponding to the charging gun 22, wherein the charging gun 22 is connected to the first charging module 211; the charging gun 22 is connected to the second charging module 212 through the switching circuit S1 corresponding to the second charging module 212; the charging gun 22 is connected to the third charging module 213 through the switching circuit S2 corresponding to the third charging module 213; the charging gun 22 is connected to the fourth charging module 214 through the switching circuit S2 corresponding to the third charging module 213 and the switching circuit S3 corresponding to the fourth charging module 214. The charging module 21 is used to convert the AC power into a DC power of a certain voltage and output the DC power to the charging gun 22. The charging module 21 may include an input rectifier and filter module, a DC power DC / AC power conversion module, a high-frequency transformer, an AC / DC rectifier module, a DC / DC conversion module, an output filter module and a monitoring and protection module.

To ensure that the output voltage is adapted to the battery charging requirements, while achieving input and output electrical isolation to improve system safety, the AC / DC rectifier module rectifies the high-frequency AC power into DC power again for subsequent DC / DC conversion. The DC / DC conversion module adjusts and stabilizes the voltage and current of the rectified DC power, and outputs a charging voltage and current that meets the battery characteristics. The output filter module filters the output of the DC / DC module to reduce voltage and current ripple, ensuring that the output DC level is stable and pure. The monitoring and protection module monitors input and output voltage, current, temperature and other parameters in real time, and is equipped with overvoltage, undervoltage, overcurrent, short circuit, overtemperature and other protection functions to ensure a safe and reliable charging process. The charging module can also include other IGBT or MOSFET modules, as long as it can convert the input voltage into a voltage that can be used by the device to be charged. The power module included in the charging module is not specifically limited here. The charging gun 22 can be connected to the device to be charged to provide the corresponding power to the device to be charged. In this way, the charging device can power the device to be charged through multiple charging modules 21 and multiple charging guns 22. At the same time, compared with the method of connecting each charging module through a switching circuit, this solution reduces the number of switching circuits (that is, reduces the number of fault nodes) and improves the stability of the charging device 20.

[0218] Next, combine Figure 7 , the charging device 20 is further explained through specific examples.

[0219] Figure 7 A structural schematic diagram of another charging device provided in an embodiment of the present application includes: multiple switching circuits S, a first charging module 2101, a second charging module 2102, a third charging module 2103, a fourth charging module 2104, a fifth charging module 2105, a sixth charging module 2106, a seventh charging module 2107, an eighth charging module 2108, a ninth charging module 2109, a tenth charging module 2110, an eleventh charging module 2111, a twelfth charging module 2112, a first charging gun 221, a second charging gun 222, a third charging gun 223, a fourth charging gun 224, a fifth charging gun 225, a sixth charging gun 226, a seventh charging gun 227, an eighth charging gun 228, a ninth charging gun 229, a tenth charging gun 2210, an eleventh charging gun 2211 and a twelfth charging gun 2212.

[0220] For example, for the first charging gun 221, the first charging module corresponding to the first charging gun 221 is the first charging module 2101, the corresponding second charging module is the third charging module 2103, the fifth charging module 2105, the seventh charging module 2107, the ninth charging module 2109 and the eleventh charging module 2111, the corresponding third charging module is the second charging module 2102, and the corresponding fourth charging module is the fourth charging module 2104, the sixth charging module 2106, the eighth charging module 2108, the tenth charging module 2110 and the twelfth charging module 2112.

[0222] exist Figure 5 、 Figure 6 and Figure 7In the embodiment shown, the charging device 20 may include M charging modules 21 and M charging guns 22, where M is an integer greater than 1. In the charging device 20, the first charging module 211 corresponding to the i-th charging gun 22i is the i-th charging module 21i among the multiple charging modules 21, and i is a positive integer less than or equal to M.

[0223] Figure 8 This is a flow chart of a charging control method provided in an embodiment of the present application. Figure 8 , the method may include:

[0224] S801: Obtain a charging request corresponding to the charging gun.

[0225] The execution subject of the embodiments of the present application may be a charging device, or a charging control device provided in the charging device. The charging device may be a charging pile, a charging stack, or other device. The charging control device may be implemented through software or a combination of software and hardware.

[0226] The charging request includes the target charging power for the charging gun. By connecting the charging gun to the device to be charged, the charging gun can obtain the target charging power required by the device to be charged. For example, the target charging power could be 60 kW.

[0227] S802: Determine a first charging power of a first charging module corresponding to the charging gun.

[0228] The first charging power may be the charging power that the first charging module can provide to the charging gun.

[0229] For example, the first charging power may be 30 kW.

[0230] S803: Determine whether the first charging power is greater than or equal to the target charging power.

[0231] If so, execute S804.

[0232] If not, execute S805.

[0233] S804: Control the first charging module to charge the target object through the charging gun.

[0234] When the first charging power can meet the target charging power required by the charging gun, the charging gun is powered only by the first charging module.

[0235] S805. Determine a target charging module from multiple charging modules based on the first charging power, the target charging power, the working status of each charging module in the charging device, and the priority between the charging modules, and control the first charging module and the target charging module to charge the target object through the charging gun.

[0236] The priority between the charging modules may mean that when the first charging power of the first charging module corresponding to the charging gun does not meet the target charging power, the charging modules corresponding to the charging gun may supply power to the charging gun according to the priority.

[0237] The priority between the charging modules corresponding to any charging gun can be: the priority of the second charging module corresponding to the charging gun is greater than the priority of the third charging module corresponding to the charging gun; the priority of the third charging module corresponding to the charging gun is greater than the priority of the fourth charging module corresponding to the charging gun.

[0238] Specifically, when the first charging power corresponding to the charging gun does not meet the target charging power, the charging gun is preferentially powered by the second charging module corresponding to the charging gun. When the second charging module corresponding to the charging gun is in an occupied state, or the second charging power of the second charging module corresponding to the charging gun plus the first charging power still cannot meet the target charging power, the charging gun is powered by the third charging module and / or the fourth charging module.

[0239] The working state of each charging module can be an occupied state or an idle state. Among them, for any charging module, the occupied state may mean that the charging module is supplying power to the charging gun, and the idle state may mean that the charging module is not supplying power to the charging gun.

[0240] The target charging module may refer to a charging module determined among the second charging module, the third charging module and / or the fourth charging module corresponding to the charging gun to supply power to the charging gun when the first charging module corresponding to the charging gun cannot meet the target charging power.

[0241] Optionally, after controlling the first charging module and the target charging module to charge the target object via the charging gun, the method further includes: obtaining the current charging energy reached by the charging gun; when the current charging energy is greater than or equal to a preset charging energy, stopping power supply to the charging gun in reverse order of priority among the target charging modules. The preset charging energy is a value pre-set by the user in the charging device. For example, the preset charging energy may be 90% of the total charging energy.

[0242] For example, assuming that the current target charging module includes multiple second charging modules, multiple third charging modules and multiple fourth charging modules, if the current charging energy reached by the current charging gun is greater than or equal to the preset charging energy, then in reverse order of priority, the multiple fourth charging modules will be stopped from supplying power to the charging gun first, and then the multiple third charging modules will be stopped from supplying power to the charging gun, and finally the multiple second charging modules will be stopped from supplying power to the charging gun, until it is detected that the charging gun has reached the total charging energy, and the first charging module will stop supplying power to the charging gun.

[0243] exist Figure 8 In the illustrated embodiment, when a charging gun is required to power a device to be charged, a charging request corresponding to the charging gun can be first obtained to determine the target charging power required by the charging gun. A first charging power of a first charging module corresponding to the charging gun can be determined. A determination can be made as to whether the first charging power is greater than or equal to the target charging power. If the first charging power is greater than or equal to the target charging power, the first charging module can be controlled to charge the target object via the charging gun. If the first charging power is less than the target charging power, a target charging module can be determined from multiple charging modules based on the first charging power, the target charging power, the operating status of each charging module in the charging device, and the priority between the charging modules. The first charging module and the target charging module can then be controlled to charge the target object via the charging gun. Thus, compared to a method where power is supplied solely by the charging module corresponding to the charging gun, in this solution, when the first charging module corresponding to the charging gun does not meet the target charging power, the charging gun can be powered by the second, third, and / or fourth charging modules corresponding to the charging gun, according to a priority ranking system, thereby improving the efficiency and stability of the charging device.

[0244] Based on the above embodiments, Figure 9 , the process of determining the target charging module ( Figure 8 S805 in the embodiment is described in detail.

[0245] Figure 9 This is a schematic diagram of the process of determining the target charging module provided in the embodiment of the present application. Figure 9 , the method may include:

[0246] S901: When the first charging power is less than the target charging power, determine the difference between the target charging power and the first charging power as a first surplus power.

[0247] For example, assuming that the first charging power is 30 kW and the target charging power is 60 kW, the first remaining power is 30 kW.

[0248] S902: Determine whether there is an idle second charging module among the second charging modules corresponding to the charging gun.

[0249] If so, execute S903.

[0250] If not, execute S910.

[0251] S903: Determine the sum of the charging powers of the second charging modules in the idle state as the second charging power.

[0252] For example, assuming that there are currently idle second charging modules 1, 2 and 3, the charging power of the second charging module 1 is 15kw, the charging power of the second charging module 2 is 30kw, and the charging power of the second charging module 1 is 20kw, then the second charging power is 65kw.

[0253] S904: Determine whether the second charging power is less than the first remaining power.

[0254] If so, execute S905.

[0255] If not, execute S906.

[0256] S905: Determine the idle second charging modules as part of the target charging modules, and determine another part of the target charging modules from the third charging modules and / or the fourth charging modules corresponding to the charging gun according to the first remaining power and the second charging power.

[0257] Another part of the target charging modules can be determined in the third charging module and / or fourth charging module corresponding to the charging gun in the following manner: the difference between the first residual power and the second charging power is determined as the second residual power; the working status of each third charging module corresponding to the charging gun is determined; when there is an idle third charging module among the multiple third charging modules corresponding to the charging gun, the target charging module is determined among the idle third charging modules according to the second residual power and the charging power of each idle third charging module; when there is no idle third charging module among the multiple third charging modules corresponding to the charging gun, the target charging module is determined among the fourth charging module corresponding to the charging gun according to the second residual power.

[0258] Wherein, according to the second residual power and the total charging power of the third charging modules in the idle state, determining the target charging module among the third charging modules in the idle state further includes: determining the sum of the charging powers of the third charging modules in the idle state as the third charging power; if the third charging power is greater than or equal to the second residual power, determining the utilization rate of each third charging module according to the total output power and the total charging time of each third charging module; sorting the third charging modules in ascending order according to the utilization rate, and determining the first i third charging modules as the target charging modules in order, wherein the sum of the charging powers of the first i-1 third charging modules is less than the second residual power. Residual power, the sum of the charging powers of the first i third charging modules is greater than or equal to the second residual power; if the third charging power is less than the second residual power, the third charging module in the idle state is determined as the target charging module, and the difference between the third charging power and the second residual power is determined as the third residual power, and the fourth charging module in the idle state is determined, and the fourth charging modules are sorted in ascending order according to the utilization rate, and the first i fourth charging modules are determined as the target charging modules in order, wherein the sum of the charging powers of the first i-1 fourth charging modules is less than the third residual power, and the sum of the charging powers of the first i fourth charging modules is greater than or equal to the third residual power.

[0259] According to the second residual power, determining the target charging module in the fourth charging module corresponding to the charging gun also includes: determining the fourth charging module in an idle state, sorting the fourth charging modules in ascending order according to the usage rate, and determining the first i fourth charging modules as target charging modules in order, wherein the sum of the charging powers of the first i-1 fourth charging modules is less than the second residual power, and the sum of the charging powers of the first i fourth charging modules is greater than or equal to the second residual power.

[0260] The utilization rate of the charging module can be determined as follows: For any charging module, assuming that the total charging time of the charging module is x, the total output power is y, the weighting coefficient of the total charging time of the charging module is n, and the weighting coefficient of the total output power of the charging module is m, the utilization rate K can be expressed as:

[0261] K=nx+my

[0262] Among them, the weighting coefficient n of the total charging time of the charging module and the weighting coefficient m of the total output power of the charging module are values set in advance by the user. For example, n can be 0.3 and m can be 0.7.

[0263] S906: Determine whether the number of second charging modules in the idle state is equal to 1.

[0264] If so, execute S907.

[0265] If not, execute S908.

[0266] S907: Determine the idle second charging module as the target charging module.

[0267] S908 . Determine the usage rate corresponding to each second charging module in sequence according to the total output power and the total charging time of each second charging module.

[0268] S909: Determine a target charging module from the idle second charging modules according to the usage rates and the first remaining powers corresponding to the second charging modules.

[0269] S910: Determine a target charging module from the third charging module and / or the fourth charging module corresponding to the charging gun according to the first remaining power.

[0270] The execution process of the above steps S908-S910 can refer to step S905 and will not be repeated here.

[0271] exist Figure 9In the embodiment shown, when it is necessary to power the device to be charged through the charging gun, if the first charging power of the first charging module is less than the target charging power, the target charging module can be determined in the second charging module, the third charging module and / or the fourth charging module to power the charging gun. The difference between the target charging power and the first charging power can be determined as the first residual power; it is determined whether there is an idle second charging module in each second charging module corresponding to the charging gun. If there is an idle second charging module in each second charging module, the sum of the charging powers of the idle second charging modules is determined as the second charging power; it is determined whether the second charging power is less than the first residual power. If the second charging power is less than the first residual power, the idle second charging modules are determined as part of the target charging modules. According to the first residual power and the second charging power, another part of the target charging modules is determined in the third charging module and / or the fourth charging module corresponding to the charging gun; if the second charging power is greater than or equal to the first residual power, when the idle When the number of idle second charging modules is equal to 1, the idle second charging module is determined as the target charging module. When the number of idle second charging modules is greater than 1, the utilization rate of each second charging module is determined in sequence based on the total output power and total charging time of each second charging module. Then, based on the utilization rate and the first residual power of each second charging module, the target charging module is determined from the idle second charging modules. Based on the first residual power, the target charging module is determined from the third charging module and / or the fourth charging module corresponding to the charging gun. If there is no idle second charging module among the second charging modules, the target charging module is determined from the third charging module and / or the fourth charging module corresponding to the charging gun based on the first residual power. In this way, when the charging power provided by the first charging module is insufficient, the remaining charging modules can be ordered to power the charging gun according to the priority order based on the target charging power, thereby improving the charging efficiency of the charging device.
