[0058] The present application provides a power distribution method, device and storage medium for a charging stack, which are described in detail below. It should be noted that the description order of the following embodiments does not limit the preferred order of the embodiments of the present application. In the following embodiments, the description of each embodiment has its own emphasis. For parts that are not described in detail in a certain embodiment, please refer to the relevant description of other embodiments.

[0059] With the development of charging stacks, the power requirements of charging ports have become diversified. However, the power allocation method of charging stacks usually divides the charging modules into several fixed groups to provide power to the charging ports, resulting in uneven power allocation of charging ports with different power requirements, affecting the charging efficiency. In addition, if all charging modules in the charging stack are to be traversed to find a suitable charging module to meet the power requirements of each charging port, this power allocation mechanism will become very cumbersome and complicated.

[0060] In view of this, the present application provides a power allocation method for a charging stack, which enables the charging stack to flexibly allocate power according to the different power requirements of the charging ports, give priority to uncalled charging modules to meet the needs, and then select called charging modules, thereby maximizing the use of the power resources of the charging modules and improving the charging efficiency of the charging stack.

[0061] See also Figure 1 and Figure 2 , Figure 1 A schematic diagram of a power distribution method for a charging stack provided in an embodiment of the present application, Figure 2 An example structural diagram of a charging stack provided in an embodiment of the present application. The present application provides a power distribution method for a charging stack. The charging stack includes a plurality of charging modules and a plurality of charging ports, wherein the plurality of charging modules are connected to the plurality of charging ports in a one-to-one correspondence through corresponding charging circuits, so that the charging modules are connected to form a first charging loop, and at least part of the charging circuits are also connected to corresponding target circuits, so that the charging modules connected to at least part of the charging circuits and the charging modules connected to the corresponding target circuits form a second charging loop, and the target circuit is any other charging circuit;

[0062] In some embodiments, multiple charging circuits are connected in sequence to form a ring so that the charging modules are connected to form a first charging loop. Exemplarily, the first charging loop in the charging stack includes charging modules 1 to 12 connected in sequence to form a ring, and the second charging loop includes charging module 1 and charging module 6. Similarly, charging module 2 and charging module 4 are also the second charging loop. Therefore, the charging stack in the present application includes a first charging loop and multiple second charging loops. Furthermore, the charging stack includes multiple main contactors and multiple branch contactors. The multiple charging circuits in the first charging loop are connected in sequence through the corresponding main contactors, and the charging circuits in the second charging loop are connected to the corresponding target circuits through the corresponding branch contactors. Each charging module has a corresponding first number, and the first number of the charging port is the same as the first number of the charging module connected through the corresponding charging circuit. Each main contactor has a corresponding second number, and each branch contactor has a corresponding third number. The multiple first numbers are arranged in sequence according to the arrangement order of the multiple charging modules, and the multiple second numbers and the multiple third numbers are arranged in sequence according to the preset numbering order, wherein each charging module has a corresponding first number, which is charging module 1 to charging module 12, each main contactor has a corresponding second number, which is main contactor K1 to main contactor K12, and each branch contactor has a corresponding third number, which is branch contactor K13 to branch contactor K21.

[0063] Power allocation methods include:

[0064] Get the required power of the charging port;

[0065] If the power of the charging module connected to the charging port through the charging line does not meet the required power, poll the calling status of each charging module in the second charging loop and the first charging loop corresponding to the charging port, determine a first available module from each charging module that has not been called, and allocate the first available module to the charging port;

[0066] If the total power of all uncalled charging modules does not meet the required power, all uncalled charging modules are determined as first available modules, second available modules are determined from the called charging modules, and the first available modules and the second available modules are allocated to the charging ports.

[0067] In the present application, multiple charging modules are charging modules, which include a main charging module and a priority module. The main charging module includes 12 charging modules, and the priority module includes each charging module on the second charging loop. The present application can connect or disconnect the two charging circuits through the on and off state of the contactor, thereby achieving the purpose of calling and releasing the charging module.

[0068] In some embodiments, the required power of the charging port can be calculated based on the required current and voltage of the charging gun, so that the number of charging modules required by the charging port can be obtained by combining the power of multiple charging modules.

[0069] In some embodiments, the power of the multiple charging modules is 40KW. It should be noted that the power of the multiple charging modules can be the same or different, which is specifically set based on the design requirements of the solution, and this application does not limit this.

[0070] It should be noted that the calling status of each charging module in the second charging loop and the first charging loop corresponding to the polling charging port is specifically to obtain the calling status of each charging module in turn based on the arrangement direction of the second charging loop and the first charging loop; first poll the calling status of each charging module in the second charging loop, and then poll the calling status of each charging module in the first charging loop, that is, poll the calling status of each charging module in the second charging loop and the first charging loop in turn; wherein polling means querying one by one according to a certain order or rule, and in this application, the second charging loop and the first charging loop are polled. Among them, the charging port can be used to connect the charging gun so that the charging module supplies power to the charging gun through the charging port, and the charging module is used to provide charging power to the charging port after being called by the charging port. In addition, the charging port is connected to the charging gun for charging. After the charging gun is successfully plugged into the charging port and the payment is completed after scanning the code or swiping the card, the charging process is started, and the charging port connected to the charging gun is prioritized to start charging through the charging module connected to the corresponding charging line. Specifically, the charging module connected to the corresponding charging line is controlled to start charging. If the charging module is called by other charging ports, the charging module is released immediately. Then insulation detection is performed. After the insulation test passes, the charging module connected to the corresponding charging line is controlled to start, shut down, and then restart to complete the configuration. After pre-charging the charging module, a charging instruction is sent to the charging module to charge the charging gun.

[0071] Through the above technical scheme, it is checked whether the power of the charging module connected to the charging port through the charging line meets the required power. If it meets the demand, it is directly allocated to the charging port without allocating other charging modules to the charging port; under the premise that the power of the charging module connected to the charging port through the charging line does not meet the required power, the charging module is allocated according to the required power, and the uncalled charging module is obtained from multiple charging modules. If there is no uncalled charging module among the multiple charging modules, or the total power of the uncalled charging modules is less than the required power, the second available charging module is determined from the called charging modules and allocated to the charging port; in the present application, the uncalled charging module is called first, and then the called charging modules are called, so that the idle charging modules can be fully utilized, the waiting time and energy waste can be reduced, the waiting time can be reduced, the charging efficiency can be improved, and the frequent calling of other charging ports can be avoided, which affects the charging process of other charging ports and reduces the scheduling time of the charging stack. In addition, the calling status of each charging module in the second charging loop and the first charging loop is polled in turn, and the first available module is determined from each charging module that has not been called. The search range for obtaining the charging module that has not been called is reduced by giving priority to the second charging loop, so that the charging demand of the charging port is responded to quickly, and then the first charging loop is polled to meet the required power of the charging port as much as possible, ensuring that the power demand of the charging port is met to the greatest extent, realizing flexible scheduling and efficient utilization of the charging module. In addition, the idle charging module can be called at any time, which improves the utilization rate of the charging module.

[0072] See also Figure 3 , Figure 3 An exemplary flow chart of a power allocation method provided for an embodiment of the application. In some embodiments, the step of determining a first available module from each charging module that has not been called includes:

[0073] Polling the calling status of each charging module in the second charging loop corresponding to the charging port;

[0074] If the total power of the charging modules not called in the second charging loop meets the required power, determining a first available module from the charging modules not called in the second charging loop;

[0075] If the total power of the uncalled charging modules in the second charging loop does not meet the required power, the calling status of each charging module in the first charging loop is polled.

[0076] A first available module is determined from charging modules that are not called in the first charging loop.

[0077] It should be noted that if the total power of the uncalled charging modules in the second charging loop does not meet the required power, the final first available module includes all the uncalled charging modules in the second charging loop and all or part of the uncalled charging modules in the first charging loop, that is, the final first available module includes the first available module determined in the second charging loop and the first available module determined in the first charging loop.

[0078] In the present application, in some embodiments, if the total power of the uncalled charging modules in the second charging loop meets the required power, the number of the first available modules determined from the uncalled charging modules in the second charging loop meets the required power of the charging port; if the total power of the uncalled charging modules in the second charging loop does not meet the required power, the number of charging modules that meet the required power is selected from the uncalled charging modules in the second charging loop and the uncalled charging modules in the first charging loop. Among them, the calling status of the charging module includes uncalled and called, and the called charging module means that the charging module is called by the charging port, that is, the charging module is assigned to the charging port; the uncalled charging module means that the charging module is not called by the charging port, that is, the charging module is not assigned to the charging port.

[0079] It should be noted that if the second charging loop is polled first, the charging module therein is in a called state. Based on the different polling times, during the process of polling the first charging loop, since the charging module in the first charging loop includes part of the charging modules in the second charging loop, there may be a situation where the charging module is in a called state during the process of polling the second charging loop and then in a non-called state during the process of polling the first charging loop.

[0080] Through the above technical scheme, the charging modules are allocated according to the power demand, which effectively avoids the situation of overcharging or insufficient power of the charging port; the search range for obtaining the uncalled charging modules is reduced through the second charging loop, and the uncalled charging modules are quickly found, so that the charging demand of the charging port is quickly responded, and then the first charging loop is polled to meet the required power of the charging port as much as possible, and avoid the omission of the uncalled charging modules due to different polling times. This flexible scheduling method ensures that the power demand of the charging port is met to the greatest extent, realizes the flexible scheduling and efficient utilization of the charging modules, and improves the efficiency of the charging stack.

[0081] In some embodiments, at least part of the second charging loop further includes a motorized charging module; polling the calling status of each charging module in the second charging loop corresponding to the charging port includes:

[0082] If the second charging loop corresponding to the charging port includes a motorized charging module, determining the calling state of the motorized charging module and each charging module in the second charging loop;

[0083] If the second charging loop does not include a motorized charging module, the call status of each charging module in the second charging loop is determined.

[0084] In some embodiments, two adjacent charging modules with even numbers form a second charging loop. For example, charging module 2 and charging module 4 form a second charging loop, charging module 6 and charging module 8 form a second charging loop, and so on. Furthermore, the second charging loop formed by two adjacent charging modules with even numbers also includes a motorized charging module, which is connected to the corresponding charging circuit through a branch contactor. For example, Figure 2 The charging modules 13, 14, 15 and 16 are motorized charging modules, and the branch contactors K16 to K21 are contactors for connecting the motorized charging modules to the corresponding charging circuits, and the number of motorized charging modules in the second charging loop including the motorized charging modules is at least 1. It should be noted that forming a second charging loop with two adjacent charging modules numbered as even numbers is only one type of the second charging loop, and other second charging loops may also be included in the present application.

[0085] In some other embodiments, the multiple charging modules in the charging stack are divided into two groups, and two charging modules with odd numbers in the two groups form a second charging loop. For example, Figure 2 The charging modules 1 to 12 are divided into two groups, one of which is the charging modules 1 to 6, and the other is the charging modules 7 to 12. Then the charging module 1 and the charging module 7 form a second charging loop, the charging module 3 and the charging module 9 form a second charging loop, and so on.

[0086] Through the above technical solution, two situations of the second charging loop are provided, namely, a second charging loop including a motorized charging module and a second charging loop not including a motorized charging module, so that the polling second charging loop in the present application has a variety of power allocation mechanisms, which can more flexibly meet the needs of the charging port, so that the charging stack can better adapt to different charging scenarios and needs, and improve charging efficiency and flexibility.

[0087] In some embodiments, polling the calling status of each charging module in the first charging loop includes:

[0088] Acquire the distance between the charging port and each charging module in the first charging loop, wherein the distance between the charging port and the charging module connected through the corresponding charging line is the shortest;

[0089] The calling status of each charging module in the first charging loop is traversed in order from near to far based on the distance.

[0090] Further, in some embodiments, traversing the call status of each charging module in the first charging loop in order of distance from near to far includes:

[0091] The charging module connected to the charging port through the charging line is used as the starting charging module, and starting from the starting charging module, the calling state of each charging module in the first charging loop is determined in sequence along the first arrangement direction;

[0092] Starting from the starting charging module, the calling status of the remaining charging modules in the first charging loop is determined in sequence along the second arrangement direction, and the second arrangement direction is the opposite direction of the first arrangement direction.

[0093] Exemplarily, if charging module 5 is the starting charging module, charging module 5 to charging module 12 is the first arrangement direction, and charging module 5 to charging module 1 is the second arrangement direction.

[0094] In some embodiments, the distance can be characterized based on the charging module number, and then the calling status of each charging module in the first charging loop is polled, including:

[0095] Determine the number of the charging module connected to the charging port through the charging line as the starting number, and poll the calling status of each charging module in the first charging loop in ascending order of the number until the charging module with the largest number in the first charging loop;

[0096] The number of the charging module connected to the charging port through the charging line is determined as the starting number, and the calling status of each charging module in the first charging loop is polled in descending order until the charging module with the smallest number in the first charging loop is polled.

[0097] Through the above technical solution, the calling status of each charging module in the first charging loop is traversed in order from near to far based on the distance, which avoids the omission of charging modules and can comprehensively obtain the calling status of multiple charging modules in the charging pile to avoid the idle charging modules from being idle. It also improves the operating efficiency and reliability of the entire charging system; further, the distance is characterized based on the charging module number, and then the calling status of each charging module in the first charging loop is polled, which simplifies the complexity of distance judgment and makes the polling process more intuitive and convenient.

[0098] In some embodiments, determining a first available module from charging modules that are not called in the first charging loop includes:

[0099] Determine the distance between the charging port and each idle charging module, where the idle charging module is a charging module that is not called in the first charging loop, wherein the charging port is closest to the charging module connected through the corresponding charging line;

[0100] Determine the idle charging modules as first available modules in order of distance from near to far, until the total power of all first available modules meets the required power of the charging port;

[0101] If the total charging power of all idle charging modules does not meet the required power of the charging port, all idle charging modules are determined as first available modules.

[0102] It should be noted that before determining the first available module from the charging modules that have not been called in the first charging loop, if there are charging modules that have not been called in the second charging loop, they are all determined as first available modules and assigned to the charging port, and then some or all of the charging modules that have not been called in the first charging loop are determined as first available modules; in some embodiments, the characterization of the distance can be achieved based on the number, and then the first available module is determined from the charging modules that have not been called in the first charging loop, including: determining the difference between the first number of the charging port and the number of the candidate contactor connected to each idle charging module in the first charging loop, the candidate contactor is the main contactor, and the idle charging module is the charging module that has not been called in the first charging loop; then based on the order of the absolute value of the number difference from small to large, the idle charging modules corresponding to the number difference are determined as first available modules in sequence, until the total power of all the first available modules meets the required power of the charging port; finally, if the sum of the charging powers of all the idle charging modules does not meet the required power of the charging port, all the idle charging modules are determined as first available modules.

[0103] It should be noted that if there are multiple main contactors connected to the charging circuit where the idle charging module is located, the one with the smallest absolute value of the number difference is selected as the final idle charging module, and the number difference between the idle charging module and the connected main contactor is used as the basis for determining the distance. In addition, the characterization of the distance based on the number can also be based on the number difference between the charging port and each idle charging module. The order of the absolute value of the number difference between the charging port and each idle charging module from small to large is the distance from the charging port to each idle charging module from near to far, and then the first available module is determined from the charging modules that have not been called in the first charging loop. However, if the absolute value of the number difference is the same, it means that the distance is the same, and any one of the idle charging modules can be preferentially selected at this time.

[0104] In some embodiments, if the total power of the uncalled charging modules in the second charging loop meets the required power, the first available module is determined from the uncalled charging modules in the second charging loop. When the corresponding second charging loop includes a motorized charging module, the charging module in the second charging loop is called first, and then the motorized charging module is called; in addition, when determining the first available module from the uncalled charging modules in the first charging loop, if the required power of the corresponding charging port is not met, for the motorized charging modules included in part of the second charging loop, if the motorized charging module is in an uncalled state, the motorized charging module can be determined as the first available module. Specifically, the motorized charging module can be selected in order from small to large based on the distance from the motorized charging module to the corresponding charging port. In addition, because the national standard requires that both the positive and negative output busbars must be controlled simultaneously by contactors, the DC contactors appear in pairs, and there are 42 contactors. The present application achieves flexible scheduling and efficient utilization of charging modules by connecting charging modules and charging ports using contactor modules.

[0105] Through the above technical solution, the present application determines the idle charging modules as the first available modules based on the distance from the charging port to each idle charging module, in order from near to far, so that the charging module called by the charging port preferably takes the nearest path to avoid energy waste.

[0106] In some embodiments, determining a second available module from each of the called charging modules includes:

[0107] Determine the charging port that calls multiple charging modules simultaneously;

[0108] From the charging ports that call multiple charging modules at the same time, determine the target charging port with the largest number of charging modules called, and determine the charging module that is closest to the target charging port among all the charging modules called by the target charging port as the second available module;

[0109] If the total power of the second available module and the first available module does not meet the required power, the charging port that calls multiple charging modules at the same time is re-determined, and the target charging port with the largest number of charging module calls is determined from the charging ports that call multiple charging modules at the same time, and the charging module that is closest to the target charging port among all the charging modules called by the target charging port is determined as the second available module, until the total power of the second available module and the first available module meets the required power.

[0110] It should be noted that, in the present application, the required power of the target charging port with the largest number of charging module calls is less than the total power provided by all the charging modules called by it, that is, it far meets the required power of the target charging port. When all the uncalled charging modules are used as available modules and still cannot meet the required power, a charging module is released from the charging port with the largest number of charging modules called; in some embodiments, if there are multiple charging ports that call the same number of multiple charging modules, a charging module is released from all the charging modules called by the charging port with the largest number as the second available charging module; in other embodiments, if there are multiple charging ports that call the same number of multiple charging modules, the first target charging module with the shortest calling time is determined, and the second available module is selected from all the charging modules called by the target charging port that calls the first target charging module. Further, the second available module can be the charging module that is closest to the charging port to be allocated among the charging modules called by the target charging port; it should be noted that the first target charging module represents the charging module with the shortest calling time, that is, the charging module that was last called. The calling time of a charging module indicates the time during which the charging module is called. For example, if the charging module numbered 5 is called by the charging port numbered 3, and then the charging module numbered 5 is called by the charging port numbered 4, the calling time is recalculated after the charging module numbered 5 is called by the charging port numbered 4. It is understandable that when designing the number of charging modules in a charging stack, those skilled in the art can ensure that at least one charging module is reserved for charging in the charging port that has called the charging module, and the power of the remaining charging modules in the charging stack can meet the power requirements of any charging port on the market.

[0111] Through the above technical solution, iterative execution is performed to determine the target charging port with the largest number of charging module calls from the charging ports that call multiple charging modules at the same time, and determine the charging module closest to the target charging port among all the charging modules called by the target charging port as the second available module, until the total power of the second available module and the first available module meets the required power. It ensures that the output of the charging stack can meet the charging demand to the maximum extent, and also realizes the refined management and efficient use of charging resources by dynamically adjusting the charging mechanism.

[0112] In some embodiments, the calling state includes a called state and an uncalled state; assigning the first available module and the second available module to the charging port includes:

[0113] Disconnecting the second available module from the charging port of the called second available module, so that the second available module switches from the called state to the uncalled state;

[0114] The charging port is connected to the first available module and the second available module respectively, so as to allocate the first available module and the second available module to the charging port.

[0115] In the present application, the second available module is disconnected from the charging port of the called second available module so that the second available module is switched from the called state to the uncalled state, specifically, the contactor connected between the first charging circuit and the second charging circuit is disconnected so that the second available module is disconnected from the charging port of the called second available module, the first charging circuit is the charging circuit connected to the charging port of the called second available module, and the second charging circuit is the charging circuit connected to the second available module. The charging port is connected to the first available module and the second available module so that the first available module and the second available module are assigned to the charging port, specifically, the contactor connected between the second charging circuit and the fourth charging circuit is closed, and the contactor connected between the third charging circuit and the fourth charging circuit is closed so that the charging port is connected to the first available module and the second available module, the third charging circuit is the charging circuit connected to the first available module, and the fourth charging circuit is the charging circuit connected to the charging port to which the first available module and the second available module are assigned.

[0116] Exemplarily, the first charging circuit is a charging circuit connected to the charging port numbered 2, and the second charging circuit is a charging circuit connected to the charging module numbered 4, and then the contactors K2 and K3 are disconnected to disconnect the second available module from the charging port that has called the second available module. It should be noted that the contactor that disconnects the connection between the first charging circuit and the second charging circuit can also be used to perform on-off control of other contactors according to the contactor structure of the charging pile to achieve on-off control between the first charging circuit and the second charging circuit. The third charging circuit is a charging circuit connected to the first available module numbered 2, and the fourth charging circuit is a charging circuit connected to the charging port to which the first available module and the second available module are assigned, and then the contactors K2 and K3 are closed to allocate the first available module and the second available module to the charging port. It should be noted that the disconnection and closing of the contactor is used to assist the allocation between the charging module and the charging port, and does not mean that the charging circuits connected by the contactor closure are all allocated. The allocation of the charging module and the charging port is executed based on the allocation method mechanism.

[0117] It should be noted that the two ends of a contactor can also be connected to two non-adjacent charging circuits. Then, the contactor connecting the two non-adjacent charging circuits can be disconnected or closed to call or release the charging module, thereby reducing the number of contactors and simplifying the control of the contactors. Among them, the contactor is an electrical switching device, whose main function is to control the on and off of the current during the charging process.

[0118] It should be understood that when allocating the first available module and the second available module to the charging port, it is necessary to first detect the contactor connected to the charging circuit connected to the first available module and the second available module. If the contactor is closed, in order to ensure safety, it is necessary to disconnect the contactor and wait until the allocation plan of the first available module and the second available module is completed, and then close the corresponding contactor to prevent repeated operation and malfunction of the contactor, thereby not affecting the charging of other charging ports.

[0119] Through the above technical solution, through the flexible scheduling of the contactor module, the rapid switching and efficient utilization of the charging module can be achieved, thereby improving the overall performance of the charging stack. If the charging port calls or releases a charging module that is not connected through a charging line, the contactor between the corresponding charging line of the charging port and the corresponding charging line of the charging module is closed or disconnected, thereby achieving the effect of calling or releasing the charging module. In addition, the contactor can play a protective role in the circuit. When other components or devices in the charging stack fail or are abnormal, the contactor can quickly disconnect the circuit to avoid problems such as excessive current or circuit short circuit, thereby protecting the safety of the charging stack and related equipment.

[0120] In some embodiments, multiple charging modules are charging modules, and the charging modules include a main charging module group and a priority module. The main charging module group includes each charging module on the first charging loop, and the priority module includes a motorized module, and the motorized module includes a motorized charging module; multiple branch contactors are branch contact modules, and the branch contact modules include motorized contact modules and quick contact modules. The motorized contact modules include motorized contactors, and the quick contact modules include quick contactors. The main charging module group is divided into a first module and a second module. The motorized contactor connects the charging module in the first module to the motorized module, and the motorized module includes at least one motorized charging module. The charging lines connected to the charging modules in the second module are divided into two groups, and the quick contactor jumps the two groups of charging lines one by one. Figure 2As shown, the main charging module includes charging modules 1 to 12, the motorized module includes charging modules 13 to 16, the motorized contact module includes contactors K16 to K21, the quick contact module includes contactors K13 to K15, the first module includes charging modules 2, 4, 6, 8, 10 and 12, charging modules 2 and 4 are connected to charging modules 13 and 14 via contactors K16 and K17, and the charging modules 6 and charging module 8 are connected to charging module 15 through contactors K18 and K19, charging module 10 and charging module 12 are connected to charging module 16 through contactors K20 and K21, and the second module includes charging module 1, charging module 3, charging module 5, charging module 7, charging module 9 and charging module 11, charging module 1 and charging module 7 are connected through contactor K13, charging module 3 and charging module 9 are connected through contactor K14, and charging module 5 and charging module 11 are connected through contactor K15.

[0121] This application first determines the module that meets the power requirements of the charging port the fastest, and quickly finds the uncalled charging module from the motorized charging module with motorized contactor conduction or the charging module with quick contactor conduction, and uses it as the first calling module, that is, the first available module, to achieve fast switching and efficient utilization of the charging module, thereby improving the overall performance of the charging stack; at the same time, it can effectively improve the utilization rate of the charging module and can flexibly meet various different power requirements. At the same time, the use of jumper connection can greatly reduce the number of contactors and achieve the purpose of cost reduction.

[0122] In some embodiments, when M is an even number, 2Ma charging modules selected from the main charging module group are used as the first module, and the remaining 2Mb charging modules in the main charging module group are used as the second module; wherein M=2Ma+2Mb, Ma≤Mb, and M is the total number of charging modules in the main charging module group; two adjacent charging modules in the first module are sequentially used as a group of first sub-modules to obtain Ma groups of first sub-modules, exemplarily, as Figure 2 As shown, charging module 2 and charging module 4 are used as a group of first submodules, charging module 6 and charging module 8 are used as a group of first submodules, and so on, the first submodule is the second charging loop; Ma group first submodules are connected to Ma group motorized modules one by one through Ma group motorized contact modules, for example, Figure 2As shown, charging module 2 and charging module 4 are connected to motorized charging module 13 and charging module 14 through motorized contactors K16 and K17; in addition, the Mb charging modules with smaller numbers and the Mb charging modules with larger numbers in the second module are connected one by one in sequence through Mb branch contactors. For example, charging module 1 and charging module 7 are connected through branch contactor K13, charging module 3 and charging module 9 are connected through branch contactor K14, and so on. It can be understood that the charging module in the first module is greater than or equal to the charging module in the second module. In some embodiments, there are 1 or 2 charging modules in the motorized module, and there are 2 motorized contactors in the motorized contact module; the 2 motorized contactors in the motorized contact module are connected one by one to the 2 charging modules in the first submodule; the quick contact module includes Mb contactors, and the Mb charging modules with smaller numbers and the Mb charging modules with larger numbers in the second module are connected one by one in sequence through Mb branch contactors. Furthermore, the second module is divided into Mb charging modules with smaller numbers and Mb charging modules with larger numbers; the charging circuit connected to the Mb charging modules with smaller numbers is the first branch, and the charging circuit connected to the Mb charging modules with larger numbers is the second branch. The Mb charging circuits in the first branch are sorted by number and correspond one-to-one to the Mb charging circuits in the second branch, and are jump-connected one-to-one through Mb branch contactors respectively. Specifically, the first Mb charging modules in the second module are taken as one group and the last Mb charging modules are taken as another group. The two charging modules with the smallest numbers are selected from the two groups respectively, and are connected through a branch contactor. Similarly, the two charging modules with the next smallest numbers are selected from the two groups respectively, so that the Mb charging modules in the two groups are corresponded one-to-one in order of number from small to large, and are connected one-to-one through Mb branch contactors.

[0123] The power allocation method of the charging stack of the present application first queries the total number M of charging modules, the total power Q of the charging stack, and the maximum number of guns N, that is, the number of charging ports; the charging modules numbered 1, 3, and 5 in the second module correspond to the charging modules numbered 7, 9, and 11. If the number X of the charging port is an even number, and the charging port numbered X+2 is not charged and the charging module numbered X+2 is an idle charging module, the charging module with the same code as the charging port is preferentially allocated, followed by the charging module with X+2, and then the mobile charging module is allocated; if the number X of the charging port is an odd number, and the charging port numbered X+6 is not charged and the charging module numbered X+6 is an idle charging module, the charging module with the same code X as the charging port is directly allocated, and then the charging module with the code X+6 is preferentially allocated; finally, if the total power of the uncalled charging modules in the second charging loop corresponding to each charging port does not meet the required power, the calling status of each charging module in the first charging loop is polled, and the first available module is determined from the uncalled charging modules in the first charging loop, and then if the total power of all the uncalled charging modules does not meet the required power, all the uncalled charging modules are determined as the first available modules, and the second available modules are determined from the called charging modules, and the first available modules and the second available modules are allocated to the charging port until the required power of the charging port is met or charging is completed.

[0124] The embodiment of the present invention divides the main charging module group into a first module and a second module, and connects them through a main contactor and a branch contactor respectively, so as to more flexibly schedule and match the charging modules, thereby meeting various different power requirements. At the same time, by numbering and grouping the charging modules, the uncalled charging modules can be quickly found and allocated to the charging port, further improving the efficiency and availability of the charging stack.
