Description

Technical Field

[0001] The present application relates to the field of charging piles, and more specifically, to a charging control method and related devices. Background Art

[0002] In order to improve the convenience and reliability of charging, a certain number of charging piles will be built in charging stations. When the vehicle needs to be charged, it can drive to the charging pile and use the charging gun of the charging pile to charge.

[0003] During the vehicle charging process, the charging power of the vehicle is not constant, but will vary due to different charging periods. In some cases, in the early stage of vehicle charging, the charging power will gradually increase until it reaches a stable output power value, and then it will be output at this power value for a period of time. In the later stage of vehicle charging, the charging power will decrease as the battery SOC (State Of Charge) increases. In this way, during the entire vehicle charging process, the charging pile does not output at a higher power value all the time, which will make the output power utilization rate of the charging pile low.

[0058] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0059] In order to improve the convenience and reliability of charging, a certain number of charging piles will be built in charging stations. When the vehicle needs to be charged, it can drive to the charging pile and use the charging gun of the charging pile to charge.

[0060] During vehicle charging, Figure 1 As shown, the charging power demand of the vehicle is roughly divided into three stages: charging power rising, charging power stable output and charging power falling. In the charging power rising stage, due to the low power demand of the vehicle, some power will not be used at this time. The charging power rising stage is followed by the charging power stable output stage. The power provided in this stage can be determined according to the power required by the vehicle. It may be full power output or not. In the charging power falling stage, the charging power of the vehicle will decrease as the battery SOC increases. At this time, some power will not be used, making the output power utilization rate of the charging pile low, which in turn affects the income of the occupant of the charging pile.

[0061] Specific as Figure 2 As shown, taking the charging power decreasing stage as an example, when the SOC of the vehicle reaches a certain level, the power demand for the charging pile will be reduced, and part of the power of the charging pile will be unused. This part of the power will cause power waste because it is not used.

[0062] To solve the above-mentioned problems, an embodiment of the present application provides a charging control method. The execution subject of the charging control method may be a charging controller, which may be a local dispatching middle station in a charging station, and the local dispatching middle station may control all charging piles in the charging station.

[0063] In actual applications, the charging piles provided in the charging station include first-type charging piles and second-type charging piles. The first-type charging piles are internally provided with a power module for providing electric energy, while the second-type charging piles are internally provided with no power module for providing electric energy.

[0064] Specifically, during the rising or falling stage of the charging power during the vehicle charging process, in order to use the power modules released by the charging piles to charge other vehicles to improve the utilization rate of the output power of the entire station. In the embodiment of the present application, some normal charging piles have been installed in the charging station, that is, on the basis of the first type of charging piles with power modules, some charging extension piles without power modules are installed, which are called second type charging piles in this embodiment. Since the second type of charging piles are not installed with power modules, the volume of the second type of charging piles can be very small and occupy less space.

[0065] The second type of charging pile has the same structure as the first type of charging pile except that the power module is not installed. Figure 3As shown, the left side is the first type of charging pile, and the right side is the second type of charging pile, that is, the charging extension pile. The piles are connected by a power output cable to ensure that the first type of charging pile on the left can transfer power to the second type of charging pile on the right. All charging piles are connected in series, that is, the first type of charging pile and the second type of charging pile are connected in series. Taking the existence of three first type charging piles and two second type charging piles as an example, the three first type charging piles are 1# first type charging pile, 2# first type charging pile and 3# second type charging pile, and the two second type charging piles are 1# second type charging pile and 2# second type charging pile. The series connection in this embodiment refers to 1# first type charging pile, 2# second type charging pile, and 3# second type charging pile connected in series with 1# second type charging pile, and 1# first type charging pile, 2# first type charging pile, and 3# first type charging pile connected in series with 2# second type charging pile, that is, to ensure that each first type charging pile and each second type charging pile are connected with a power output line, to ensure that each first type charging pile can output power to the second type charging pile.

[0066] Since the second type of charging pile uses the idle power modules in the first type of charging pile to charge the vehicle, and the first type of charging pile is affected by its own charging of the vehicle, it will constantly adjust the number and power of the power modules used internally, so the power information of the second type of charging pile will change. For example, the load of the first type of charging pile (such as a vehicle) may reduce or increase the power, then the power module called internally by the first type of charging pile will change, affecting the number and power of the power modules used by the second type of charging pile, causing the power information of the second type of charging pile to change.

[0067] Inside the charging station, all charging piles communicate through the local area network, such as Figure 3 As shown, the solid line is the communication line. When the second type charging pile charges the vehicle, the first type charging pile and the second type charging pile exchange charging information through the communication line.

[0068] When the first type of charging pile and the second type of charging pile are installed, all charging piles establish a local LAN. In the LAN, the first type of charging pile and the second type of charging pile are connected through a switch to ensure that the TCU (Telematics Control Unit) in all charging piles can communicate through the switch. The switch can also be connected to a router, which is connected to an external router to ensure that all charging piles can communicate with the local dispatching center through the router. Figure 4 The communication network topology shown.

[0069] Figure 4In the embodiment, for the first type of charging pile, at least one power module is configured inside, such as 1# power module, 2# power module...n# power module, where n is a positive integer. In actual scenarios, some power modules inside the same first type of charging pile may be outputting power, while some power modules may be in an idle state. It should be noted that the types of power modules inside different first type charging piles may be the same, such as all 30KW power modules or all 60KW power modules. In addition, the types of power modules inside different first type charging piles may also be different, such as some first type charging piles have 30KW power modules, and some first type charging piles have 60KW power modules. The specific configuration can be based on the actual scenario. If it is for the convenience of management and maintenance, the same type of power modules can be used.

[0070] For the second type of charging pile, the charging pile is only equipped with a TCU but no power module.

[0071] In addition, if Figure 4 As shown, the display interface of the charging pile will also display the working status, such as: idle or charging.

[0072] Before the charging pile is officially used, it is necessary to register the charging pile. At this time, the first type of charging pile and the second type of charging pile can send registration information to the local scheduling middle station. Among them, the registration information may include pile module information, such as the power and quantity of the power module. In addition, the registration information also includes the unique identification of the charging pile, such as SN (Serial Number, serial number) number, location and other information. After receiving the registration information, the local scheduling middle station performs registration operations on the first type of charging pile and the second type of charging pile based on the registration information. During the specific registration, the registration information of the charging pile can be recorded in the database, and the registered charging pile can be controlled by the local scheduling middle station. When charging the vehicle, the subsequent charging pile will also upload the charging information (such as TCU operation information, power module power, operating status, etc.) to the local scheduling middle station, which is responsible for allocating the charging power of the charging piles of the entire station.

[0073] In this embodiment, the usage scenarios of the first type of charging pile and the second type of charging pile may be:

[0074] 1) When the first type of charging piles in the charging station do not need to charge at peak power, there will be idle power modules inside the first type of charging piles. In order to make full use of these power modules, the second type of charging piles can be added to expand the charging station. Since the second type of charging piles are not equipped with power modules, the cost of the second type of charging piles is low. On the one hand, the procurement cost of the charging piles can be reduced. On the other hand, more charging piles can be configured to charge more cars, which can maximize the power of the charging piles and increase profits.

[0075] 2) In some scenarios where there are many charging vehicles and they stay for a long time, such as supermarkets, a large number of new energy vehicles need more charging piles to meet the needs of users for charging. If ordinary charging piles, i.e., first-type charging piles, are installed, the first-type charging piles will also have idle power modules, resulting in low output power utilization. At this time, the second-type charging piles in this application can share the redundant power of other charging piles, thereby improving the output power utilization of the entire station.

[0076] 3) For high-power charging piles, due to the high unit price, some charging stations will not install a large number of high-power charging piles. If high-power charging piles are installed, their utilization rate is not high, and the relatively high utilization rate is on other charging piles with lower power. The second type of charging pile installed in the embodiment of the present application can increase the frequency of use of the high-power charging pile module, and at the same time improve the efficiency of the power module, bringing higher economic benefits.

[0077] If there are a large number of charging piles in the charging station, the power module of the charging pile is the core module of the entire charging pile. Once a fault occurs, it is very difficult to troubleshoot the problem. For operation and maintenance personnel, the maintenance of the charging pile will be very cumbersome and difficult. The second type of charging pile used in the embodiment of the present application is not equipped with a power module, and the probability of problems will be greatly reduced, which can reduce a lot of operation and maintenance work in terms of operation and maintenance. In addition, since the power module is not configured, the second type of charging pile is less likely to be damaged, and the service life of the second type of charging pile can also be increased. In addition, since the second type of charging pile is not equipped with a power module, it is smaller in size and has low transportation requirements.

[0078] In another embodiment of the present application, after configuring the second type of charging pile, the unused power in the first type of charging pile can be used for the newly added second type of charging pile. The second type of charging pile can charge the vehicle, thereby improving the charging power utilization rate during the charging power rising or falling stage, thereby increasing profits.

[0079] It should be noted that although there is unused power in the rising stage of charging power, as the demand for power continues to increase, the unused power modules in the charging pile, that is, the idle power modules, may also be used. If the idle power modules inside the charging pile in the rising stage of charging power are used to provide power for the second type of charging pile, there will be a period of use, and the idle power modules may be used by the original pile. However, since the power modules have been occupied by the second type of charging pile, the original pile may not be able to use enough power to charge the vehicle, reducing the charging reliability of the charging pile. As for the idle power modules in the charging pile in the falling stage of charging power, since the original pile will continuously release new power modules in the falling stage of charging power, and the previously released power modules will no longer be used by the original pile, this part of the power modules can be continuously used by the second type of charging pile, ensuring the power amount of the power modules used by the second type of charging pile. Therefore, in the embodiment of the present application, if there is a non-operating first type charging pile, the non-operating first type charging pile is used preferentially to provide charging power for the second type charging pile; if the non-operating first type charging pile is insufficient, the idle power module in the first type charging pile whose charging power of the vehicle is in the charging power decreasing stage is preferentially used to provide charging power for the second type charging pile; if the power of the first type charging pile whose charging power of the vehicle is in the charging power decreasing stage is insufficient, the first type charging pile whose charging power of the vehicle is in the charging power increasing stage is used to provide charging power for the second type charging pile; if the required power is still insufficient, the idle power module in the first type charging pile whose device is in the charging power stable output stage can be used to provide charging power for the second type charging pile; if it is still insufficient, all the idle power modules that can be called are temporarily used to charge the device, and when a new power module is released, the new power module is called to charge the device.

[0080] Based on the above content, the charging control method in this application refers to Figure 5 , which may include:

[0081] S11. Obtain information of a target charging pile.

[0082] Wherein, the target charging pile is determined by the target device.

[0083] The target device refers to the device to be charged, such as a vehicle or other device. The following embodiments are illustrated by taking a vehicle as an example. The target charging pile refers to the charging pile for charging the target device, which can be a first type charging pile or a second type charging pile. In this embodiment, the target charging pile is determined by the target device, which means that the target charging pile can be determined based on the selection of the target device, or based on the analysis of information such as the location of the target device and the charging demand power.

[0084] In actual scenarios, since there are multiple first-type charging piles and multiple second-type charging piles in the charging station, after the user drives into the charging station, there may be multiple charging piles available, and a charging pile will be selected for charging. If the selected charging pile is the first-type charging pile, charging control is performed in accordance with the conventional charging method. If the selected charging pile is the second-type charging pile, charging control needs to be performed in accordance with the charging control method in the embodiment of the present application.

[0085] In one embodiment of the present application, the target charging pile can be selected in a variety of ways, such as determining a unique charging pile based on the location of the target device, the required charging power, user selection, etc., and the charging pile is the target charging pile.

[0086] After the target charging pile is determined, the target charging pile has corresponding information, which may be the above-mentioned SN, location, etc., which can uniquely determine a charging pile. For example, the location may be the YYth in the XX row.

[0087] S12: when the information of the target charging pile indicates that the target charging pile is the second-type charging pile, obtain information of M target power modules located in the first-type charging pile.

[0088] Among them, the target power module is an idle power module in the first type of charging pile, and M target power modules are selected from the idle power modules inside the first type of charging pile to charge the target device. In one implementation, M is a positive integer, which can be one or more, and can be set according to the power demand of the target device or determined according to the power modules that the current charging station can provide. For example, when the current charging station can provide enough power modules, taking the output power of each power module as the same, M=the charging demand power of the target device / the output power of each power module.

[0089] In actual scenarios, after determining the information of the target charging pile, a charging pile can be uniquely determined based on the information, and the charging pile can be a first type charging pile or a second type charging pile. When the information of the target charging pile indicates that the target charging pile is the second type charging pile, it means that the second type charging pile is used to charge the target device at this time.

[0090] Since the second type of charging pile is not equipped with a power module, the charging pile cannot directly charge the vehicle, and it is necessary to use the idle power module in the first type of charging pile to charge the vehicle.

[0091] In general, since the power modules in all the charging piles in the power station cannot output electric energy at the same time, there will be idle power modules inside all the first-type charging piles. Specifically, there may be one idle power module or multiple idle power modules. If there is only one idle power module in all the first-type charging piles, then this power module is the target power module in the embodiment of the present application. If there are multiple idle power modules in all the first-type charging piles, it is necessary to select a suitable target power module from the multiple idle power modules. Specifically, the selection of M target power modules can be carried out using data such as user selection, charging power of the power module, health, and charging demand power required by the vehicle.

[0092] After M target power modules are selected, each target power module has corresponding information, such as power, SN, location, etc.

[0093] S13: Control the target charging pile to call M target power modules to output electric energy to charge the target device.

[0094] After selecting the target power module, the output power of the target power module can be Figure 3 The power output line shown is output to a target charging pile, which outputs the electric energy received from the target power module to the target device to charge the target device.

[0095] In this embodiment, since the charging pile does not output at a higher power value all the time during the entire vehicle charging process, there will be an idle power module inside the first type of charging pile. In order to utilize the charging power of the idle power module, a second type of charging pile that is not equipped with a power module is set in the charging station, so that the second type of charging pile can use the idle power module in the first type of charging pile to charge the target device, thereby achieving full utilization of the charging power of the idle power module and improving the output power utilization rate of the charging pile.

[0096] In another implementation of the present application, before obtaining the information of the target charging pile, it is necessary to first determine the target charging pile. The present application introduces the specific implementation of determining the target charging pile. Before obtaining the information of the target charging pile, it also includes:

[0097] When a charging request from the target device is received, a candidate charging pile that can provide electric energy is determined.

[0098] Specifically, taking the target device as a vehicle, after the vehicle enters the charging station service area, it establishes a communication connection with the local dispatching center, and the content of the communication connection can be displayed on the display interface of the vehicle terminal. If the user wants to charge the vehicle, he can click on the charging service on the vehicle terminal, and the local dispatching center will put the usage status of all charging piles in the current charging station and the geographic information of the charging piles into the vehicle terminal. Among them, the usage status of all charging piles and the geographic information of the charging piles can be shown as follows: Figure 6 shown. Figure 6 In the charging station service area, the vehicle communicates with the local dispatching center through agreed communication methods, such as near-end wireless projection, local area network, etc. The information sent by the local dispatching center to the vehicle can include the identification of the charging pile, such as 1#, 2#, etc., and it will also show whether the charging pile is currently charging or idle. If it is in the charging state, it will also show the charging progress, such as 70%.

[0099] In addition to the above information push, the local dispatching center will also determine the candidate charging piles that can provide charging services. It can be understood that the candidate charging pile can be any charging pile in the power station.

[0100] In one embodiment, the operating status of the charging pile may be acquired, so as to determine the candidate charging pile based on the operating status of the charging pile.

[0101] Specifically, different charging piles have different operating states, such as charging or idle. Since the charging pile in use has been used to charge other vehicles, if the charging pile has no available charging gun or available power module, the charging pile in use cannot charge the vehicle. Therefore, charging piles in an idle state can be used as candidate charging piles.

[0102] Of course, if the charging pile is a multi-gun device, then even if the charging pile is in charging, it is possible to further determine whether the charging pile has idle charging guns and idle power modules. If there are idle charging guns and idle power modules, then the charging pile can also be used as a candidate charging pile.

[0103] In another embodiment, the charging requirement information of the target device may be obtained first, and further, a candidate charging pile capable of charging the target device may be determined according to the charging requirement information of the target device.

[0104] The charging requirement information includes at least one of the charging requirement power and the device location.

[0105] It is understandable that due to the different remaining power of different vehicles, the charging requirements of different vehicles are different. The charging requirements can be reflected by the charging demand power. Different vehicles have different charging demand powers. At this time, the candidate charging piles can be determined according to the charging demand power.

[0106] Specifically, a charging pile in a power station whose output power can meet the required charging power can be used as a candidate charging pile. For example, if the required charging power of the vehicle is 40 kW, a charging pile in a power station whose output power is greater than or equal to 40 kW is determined as a candidate charging pile.

[0107] In another embodiment, in general, the driver of the vehicle will choose a charging pile that is closer to the vehicle for charging, so the candidate charging pile can also be determined based on the device location. Specifically, based on the current location of the vehicle, the charging pile within a threshold distance from the vehicle can be determined as a candidate charging pile.

[0108] Of course, the candidate charging piles can also be determined in combination with the required charging power of the vehicle and the current location of the vehicle. For example, the charging piles in the power station whose output power can meet the required charging power and whose distance from the vehicle is within a threshold can be determined as candidate charging piles.

[0109] It can be understood that the candidate charging pile can be a first type charging pile or a second type charging pile.

[0110] It should be noted that since the second type of charging pile is not equipped with a power module, it is necessary to indirectly use the idle power module in the first type of charging pile to charge the vehicle. Therefore, the second type of charging pile can only be determined as a candidate charging pile when there is at least one idle power module in the entire power station. If there is no idle power module in the first type of charging pile, it means that each first type of charging pile is in full power use, and the candidate charging pile cannot be determined at this time.

[0111] In one embodiment, when specifically determining the charging piles that can provide charging services, it is also necessary to consider whether the total charging power of the charging station has reached the upper limit. Generally, a power threshold is set for a charging station, which is the maximum charging power of the charging station, that is, the maximum charging capacity of the charging station. The power threshold can be a pre-set fixed threshold, or it can be a dynamic value that is automatically adjusted based on usage. For example, when the charging station adds or reduces charging piles, or when the charging piles fail, the number of available charging piles changes. At this time, the charging power that the entire charging station can provide changes, and the power threshold will also change accordingly.

[0112] In the specific implementation, the total charging power of the current charging station should be obtained, where the total charging power of the charging station refers to the sum of the charging powers of all running charging piles. Specifically, the charging station can obtain the charging power of each running charging pile in real time, calculate the sum of the charging power of all running charging piles, and use it as the total charging power of the charging station.

[0113] If the total charging power of the charging station is greater than the power threshold, it means that the current charging station has reached its maximum charging capacity. In order to ensure the safety of the charging station, no new vehicles are allowed to be charged.

[0114] If the total charging power is not greater than the power threshold, it means that the current charging station still allows charging operations for new vehicles. At this time, the candidate charging pile can be determined. After the candidate charging pile is determined through the above steps, if there is only one candidate charging pile, the candidate charging pile is determined as the target charging pile.

[0115] If there are multiple candidate charging piles, it is necessary to select a suitable charging pile from the multiple candidate charging piles as the target charging pile. Specifically, a charging pile that meets a preset condition among the multiple candidate charging piles is determined as the target charging pile.

[0116] In this embodiment, when it is determined that the target device has a charging demand, some candidate charging piles that can provide electrical energy can be screened out first, and then the target charging pile can be further determined on this basis, so that a charging pile that meets the actual power demand and / or user demand can be screened out to meet the user's charging needs.

[0117] It is understandable that the preset condition can be implemented in a variety of ways according to actual needs, and a charging pile that meets the preset condition among multiple candidate charging piles is determined as a target charging pile, including:

[0118] Determine a charging pile selected by a user from a plurality of candidate charging piles as a target charging pile;

[0119] Alternatively, the charging pile closest to the target device among the multiple candidate charging piles is determined as the target charging pile;

[0120] Alternatively, a charging pile that matches the required charging power among multiple candidate charging piles is determined as a target charging pile.

[0121] It can be understood that the local scheduling middle station can push the information of the candidate charging piles that can provide electric energy to the target device for the target device to select.

[0122] It can be understood that all candidate charging piles in the power station can be pushed to the target device, or only some of the candidate charging piles in the power station can be pushed to the target device.

[0123] In one implementation, the information of all candidate charging piles in the power station can be pushed to the vehicle terminal, and the display interface of the vehicle terminal will display the information of these candidate charging piles, for example, Figure 6 As shown, the idle charging piles 5#, 6# and 7# are candidate charging piles for the power station, and the display interface of the vehicle computer can display the icons of charging piles 5#, 6# and 7#. Of course, the display method of the charging pile information on the screen is not limited, and text information can also be displayed.

[0124] In another implementation, in order to improve the efficiency of users screening charging piles, after determining the candidate charging piles, only some of the candidate charging piles located within the specified area range (such as within a few meters) of the target device can be pushed to the target device based on the location of the target device, so that the target device can make a selection. For example, after a vehicle enters a charging station, only the candidate charging piles within 10 meters around the vehicle can be pushed to the target device.

[0125] In another implementation, after the candidate charging piles are determined, only the charging piles that can meet the required charging power may be pushed to the vehicle based on the required charging power.

[0126] Of course, there are other ways to determine only some of the candidate charging piles to be pushed. For example, the charging power and distance can be combined, or the maximum number of pushes can be specified, which will not be explained here one by one.

[0127] In one embodiment, after all or part of the information of the candidate charging piles is pushed to the vehicle, the user can select a target charging pile according to actual needs.

[0128] For example, if multiple candidate charging pile icons are displayed on the vehicle screen, the user can select the charging pile icon according to actual needs to determine the target charging pile. Figure 6 As shown, the user clicks the icon of charging pile 5#, and charging pile 5# is determined as the target charging pile. Of course, the display method of the charging pile information on the screen and the user's selection method of the charging pile are not limited here, and one of the charging piles can also be selected by voice or other methods.

[0129] In some embodiments, there is no need to push the information of the candidate charging piles to the target device, but the charging piles can be directly determined.

[0130] Specifically, the charging pile that is closest to the target device (such as a vehicle) among the candidate charging piles may be directly determined as the target charging pile.

[0131] Specifically, the charging pile among the candidate charging piles that matches the charging power requirement of the target device (such as a vehicle) can be determined as the target charging pile. It is understandable that there may be multiple charging piles that match the charging power requirement of the vehicle, so any one of them can be directly determined as the target charging pile, or the charging pile that meets the charging power requirement and is closest to the target charging pile can be directly determined as the target charging pile in combination with the distance information.

[0132] In other embodiments, there is no need to push the information of the candidate charging pile to the target device, and the target charging pile can be determined by directly detecting the behavior of the vehicle.

[0133] Specifically, if it is detected that the vehicle is parked in front of a candidate charging pile, it means that the target device has a need to use the charging pile for charging. At this time, the charging pile can be directly determined as the target charging pile.

[0134] In addition, if it is detected that a charging gun is inserted into the charging port of the target device, it means that the user directly selects the charging pile based on his or her own charging behavior, and the charging pile corresponding to the charging gun can be determined as the target charging pile.

[0135] In this embodiment, the target charging pile for charging the vehicle is finally determined by comprehensively considering the vehicle's charging needs, vehicle location, charging demand power and other information, and a charging pile suitable for the vehicle is recommended to the user to maximize the satisfaction of the user's needs.

[0136] In another implementation of the present application, when it is determined that the target charging pile for charging the target device is a second-type charging pile, based on the characteristic that there is no power module in the second-type charging pile, the power modules for charging the target device are all provided by the idle power modules in the first-type charging pile, but the number of idle power modules that can provide electrical energy in the first-type charging pile may be large (i.e., only a part of them is needed to meet the charging needs of the target device), or may be small (i.e., all of them cannot meet the charging needs of the target device). In one implementation, when the number of idle power modules is large, it is necessary to further select the target power module for charging the vehicle from multiple idle power modules.

[0137] It can be understood that before obtaining the information of the M target power modules located in the first type of charging pile, the method further includes:

[0138] The information of all idle power modules in the first type of charging pile is obtained, and the charging demand information of the target device is obtained.

[0139] Among them, the charging requirement information of the target device includes the charging requirement power, and the specific explanation refers to the above corresponding instructions.

[0140] Among them, for the information of all idle power modules in the first type of charging pile, since the local scheduling center stores the operating information of each first type of charging pile, such as the usage of the charging pile, the operating status of the TCU, the operating status and power of the power module, etc. Therefore, the power modules located in the first type of charging pile and in an idle state (that is, no power is output at this time) can be determined from these operating information. These power modules are idle power modules. Then, the number of idle power modules, the sum of the power of all idle power modules, and other information are counted to determine whether the charging power required by the target device can be provided. Figure 4 As shown, the operation information of charging piles such as charging pile 1#, charging pile 2#, charging pile 3# and charging pile 4# can be stored to determine which power modules are not in operation among the multiple charging piles, and the rated output power that each non-operating power module can output can be obtained respectively, so as to obtain the sum of the powers of all idle power modules.

[0141] After obtaining the sum of the powers of all idle power modules, it is necessary to determine whether the total power of all idle power modules in the first type of charging pile meets the required charging power, that is, to determine whether the sum of the powers of all idle power modules in the first type of charging pile is not less than the required charging power of the target device.

[0142] When the sum of the powers of all idle power modules in the first type of charging pile is not less than the charging power required by the target device, it means that the number of all idle power modules in the first type of charging pile is sufficient, and the second type of charging pile can use the idle power modules to provide sufficient charging power for the vehicle. In one implementation, since the number of idle power modules is sufficient, in actual situations, only some of the idle power modules may need to be called to meet the charging power required by the target device.

[0143] In one implementation, a target power module that matches the charging power requirement of the target device can be selected from all idle power modules. When screening idle power modules, two implementations are provided, which are now introduced separately. It should be noted that one of the two implementations can be implemented, and the specific implementation can be selected based on actual needs, such as efficiency.

[0144] In a first implementation, a target power module is selected based on an idle power module queue.

[0145] In actual scenarios, an idle power module can be a power module that is not loaded (i.e., other loads are connected to the charging pile), or a power module that is loaded but has no faults. The present invention only selects the target power module from these idle power modules. If a power module is loaded and in power output mode, the power module is not included in the selection range of this power module. If it is loaded, not in power output mode but has a fault, the power module is not included in the selection range of this power module.

[0146] For idle power modules, an idle power module queue can be established. If a certain power module is idle, the power module is added to the idle power module queue as an idle power module. The idle power module queue includes all the idle power modules.

[0147] It can be understood that the power modules in the idle power module queue can be sorted in a certain order, such as sorting by health, idle time, total usage time, etc.

[0148] In one implementation, the power modules in the idle power module queue are sorted by idle time, where idle time refers to the time interval between the last time a power module stopped outputting power and the current time. If sorted by idle time, power modules with longer idle time can be placed in front, and power modules with shorter idle time can be placed in the back.

[0149] In another implementation, the power modules in the idle power module queue are sorted according to the total usage time. The total usage time refers to the sum of the overall working time (i.e., output power) of the power modules. The longer the total usage time, the greater the power module loss. Therefore, the power modules with the shorter total usage time can be sorted in front, and the power modules with the shorter total usage time can be sorted in the back.

[0150] In another implementation, the power modules in the idle power module queue are sorted according to health. In actual scenarios, after a power module has been used for a long time, the power module will be worn out and its ability to provide power will decrease. At this time, in order to better use the power to provide power, if the power module is in an idle state, the health of the power module can be further analyzed. The health can characterize the power providing ability of the power module. The higher the health, the better the power module can provide power, or has better power output efficiency. The health can be calculated based on the calculation formula of the health. Since the higher the health, the better the power providing ability, in the idle power module queue, the ones with larger health values ​​can be placed in front, and the ones with smaller health values ​​can be placed in the back.

[0151] In another implementation of the present application, if the health of a power module is very low, it means that the power module has a large loss and is not suitable for frequent calls. At this time, for a power module, if the calculated health of the power module meets the health requirement, that is, the calculated health is greater than the health threshold, the power module is added to the idle power module queue as an idle power module. If the calculated health of the power module does not meet the health requirement, it will not be added to the idle power module queue, that is, at this time, only power modules with better power provision capabilities are retained in the idle power module queue.

[0152] Based on the above, when selecting a target power module from the idle power modules, the target power module can be determined from the idle power module queue in the order of arrangement until the charging demand power is met. It can be understood that according to the above example, the arrangement order can be selected in order from front to back.

[0153] Specifically, first analyze the first power module in the idle power module queue to determine whether its output power is not less than the charging power requirement of the target device. If it is less, it means that only using the first power module cannot meet the charging requirements of the target device. At this time, calculate the sum of the output powers of the first power module and the second power module. If the sum is not less than the charging power requirement of the target device, it means that the output power of the first two power modules can meet the charging requirements of the target device. At this time, the first two power modules in the idle power module queue are the target power modules. If the sum of the output powers of the first two power modules is still less than the charging power requirement of the target device, continue to calculate the sum of the output powers of the first three power modules in the idle power module queue... until the power module with the sum of power not less than the charging power requirement of the target device and the least number is selected. If the sum of the output powers of the first five power modules in the idle power module queue is greater than the charging power requirement, the first five power modules are used as target power modules.

[0154] For example, if the sum of the first few power modules is 12kw short of the charging power required by the target device, but the output power of the last power module is 20kw, then the last power module needs to be used as the target power module, that is, the sum of the power modules is not less than the charging power required by the target device and the number of power modules is the smallest. When determining the power modules, the number of power modules is rounded backwards.

[0155] It should be noted that if the idle power module queue in the embodiment of the present application is sorted according to idle time, the target power modules screened out are power modules with longer idle time, which can improve the utilization rate of power modules that are idle for a long time.

[0156] If the power modules in the idle power module queue are sorted according to the total usage time, the power modules with shorter total usage time are used first to avoid over-use of the power modules.

[0157] If the idle power module queue in the embodiment of the present application is sorted according to health, the screened target power module is a power module with a higher health level and can output power better.

[0158] In this embodiment, the power modules in the idle power module queue are serialized, such as sorted according to idle time, total usage time or health status. When the target power modules are subsequently filtered from the idle power module queue, the target power modules with longer idle time, less total usage time or higher health status can be preferentially filtered out, so as to better realize the utilization of power modules.

[0159] In the second implementation, an idle power module is selected based on the operating status of the charging pile. At this time, determining M target power modules from all idle power modules includes:

[0160] Obtain the operating information of the charging pile where each of the idle power modules is located. When the operating information of the charging pile where the idle power module is located indicates that there is a non-operating charging pile, if the number of idle power modules in the non-operating charging pile is greater than or equal to M, determine the M target power modules from the idle power modules in the non-operating charging piles; if the number of idle power modules in the non-operating charging piles is less than M, obtain the idle power modules in the operating charging piles, and determine all the idle power modules in the non-operating charging piles and at least one idle power module in the operating charging piles as the M target power modules.

[0161] In actual scenarios, since the second type of charging pile uses the idle power module in the first type of charging pile to charge the target device, if the first type of charging pile is charging other vehicles, you can choose not to call its internal idle power module first to avoid overuse of the first type of charging pile. If a first type of charging pile is not running, that is, no device is charging with the first type of charging pile at this time, you can give priority to calling the idle power module in the first type of charging pile, that is, give priority to using the idle first type of charging pile, so that the first type of charging pile is used evenly.

[0162] In the embodiment of the present application, the operation information of the charging pile where each idle power module is located can be obtained, and the operation information may include the usage of the charging pile, the operating status of the TCU, the operating status and power of the power module, etc. Subsequently, based on the usage of the charging pile, it can be determined whether the charging pile is idle or charging other devices.

[0163] In specific implementation, it is possible to determine whether there is a non-operating charging pile based on the operation information of the charging pile where the idle power module is located. The non-operating charging pile refers to a charging pile in an idle state, that is, a charging pile that is not charging a device.

[0164] If there is a charging pile that is not in operation, the power modules in the charging pile have no power output, that is, they are all idle power modules. At this time, the number of idle power modules in the charging pile that is not in operation is counted. If it is greater than or equal to M, it means that sufficient charging power can be provided for the target device. At this time, the M target power modules are determined from the idle power modules in the charging pile that is not in operation. In the specific screening, M target power modules can be randomly selected therefrom, and the sum of the output power provided by the M target power modules is not less than the charging demand power of the target device. In another implementation method, it can also be sorted according to health, total usage time or idle time, and power modules with higher health, shorter total usage time or longer idle time are given priority.

[0165] In one implementation, when a first type charging pile can provide M target power modules, the M target power modules of the same first type charging pile can be called; when a first type charging pile cannot provide M target power modules, the idle power modules of two or more first type charging piles can be used.

[0166] In addition, if the number of idle power modules in the non-operating charging pile is less than M, it means that only the idle power modules in the non-operating first type charging pile cannot provide enough charging power for the target device. At this time, the idle power modules in the operating charging pile need to be called. In specific implementation, the idle power modules in the non-operating first type charging pile can be called first, and the insufficient part can be screened from the idle power modules in the operating charging pile. When screening, various methods can be used, such as random screening, screening by health, total usage time, or sorting by idle time.

[0167] For example, if M is 5 and the number of idle power modules in the non-operating charging pile is 4, then a power module with the highest health is selected from the idle power modules in the operating charging pile for calling. In this embodiment, the target power modules are screened according to the number of idle power modules because the power modules in general charging stations are of equal power, so the target power modules can be screened based on the number. For charging stations that are not of equal power, they can be screened according to the power provided by the power modules. At this time, the target power modules with the sum of their output power greater than the charging demand power of the target device and the least number can be screened out.

[0168] In another implementation of the present application, when selecting idle power modules from the charging piles that are already in operation, priority can be given to those that are already in operation and in the late stage of charging (i.e., the device is in Figure 1 The target power module is determined in the first type of charging pile (the power reduction stage in the process) until the charging power requirement is met.

[0169] Specifically, in the first type of charging pile that is already in operation, the charged device may be in the charging power rising stage or the charging power falling stage. If it is in the charging power rising stage, the idle power module of the charging pile may be used by the original pile later, making it unstable to call the idle power module to charge the vehicle. Therefore, in the embodiment of the present application, the idle power module in the first type of charging pile where the device SOC is in the charging power falling stage is mainly used. For example, among the ten first type charging piles that are already in operation, the device power falling stage corresponding to charging piles No. 1, 3, 5, 7 and 9, then from charging piles No. 1, 3, 5, 7 and 9, the target power module that meets the charging demand power is screened out by randomness, health, total usage time or idle time.

[0170] In this embodiment, the idle power module in the first type of charging pile when the device is in the power reduction stage is used to provide power to the second type of charging pile. This can ensure that the idle power module can be used by the second type of charging pile during the entire charging process of the second type of charging pile, so that the second type of charging pile provides stable output power.

[0171] If the charging power requirement of the target device cannot be met after using all the idle power modules in the first type of charging pile that is already in operation and the device is in the power decreasing stage, the idle power modules in the first type of charging pile that is already in operation and the device is in the power increasing stage can also be used. The specific screening process refers to the corresponding instructions above.

[0172] In another implementation of the present application, if there is no first type charging pile that is not in operation, that is, all the first type charging piles are in operation at this time, the target power module can be selected from the charging piles where the device is in the power reduction stage until the charging power requirement of the target device is met. If all target power modules cannot meet the charging power requirement, the target power module can continue to be selected from the charging piles where the device is in the power increase stage until the charging power requirement of the target device is met. If the charging power requirement still cannot be met, the target power module can continue to be selected from the charging piles where the device is in the stable output stage of the charging power until the charging power requirement of the target device is met. If it still cannot be met, all the target power modules that can be called are first used to charge the device, and when there are new released power modules later, the released power modules are called to charge the device.

[0173] In another implementation of the present application, if there is no first type charging pile that is not in operation, that is, all the first type charging piles are in operation at this time, the target power module can be selected from the charging piles where the device is in the power reduction stage until the charging power requirement of the target device is met. If all target power modules cannot meet the charging power requirement, the target power module can continue to be selected from the charging piles where the device is in the stable output stage of the charging power until the charging power requirement of the target device is met. If the charging power requirement still cannot be met, the target power module can continue to be selected from the charging piles where the device is in the power increase stage until the charging power requirement of the target device is met. If it still cannot be met, all the target power modules that can be called are first used to charge the device, and when there are new released power modules later, the released power modules are called to charge the device.

[0174] In another implementation, Figure 4 As shown, in special circumstances, during the charging process of vehicle A by the first type of charging pile, such as 1# charging pile, the idle power module inside 1# charging pile is used by 3# charging pile, that is, the second type of charging pile. If vehicle A has completed charging and leaves, vehicle B uses 1# charging pile to charge at this time. When the available power modules inside 1# charging pile are insufficient, the idle power modules used by 3# charging pile need to be released, so that the power module inside 1# charging pile is used to charge vehicle B first. In addition, vehicle B can also be prompted to charge with other charging piles that can provide sufficient power. In addition, 1# charging pile can also charge vehicle B with low power first, and after the power module inside 1# charging pile is released by 3# charging pile, the released power module is added to charge vehicle B. However, in actual scenarios, the vehicle charging time is generally long, and the probability of this situation occurring is small, and it is only described as a special embodiment.

[0175] The above embodiment introduces that, when the sum of the powers of all idle power modules in the first type of charging pile is not less than the charging power required by the target device, M target power modules are determined from all idle power modules. In another implementation of the present application, when the sum of the powers of all idle power modules in the first type of charging pile is less than the charging power required by the target device, all idle power modules are determined as the M target power modules.

[0176] In actual scenarios, there may be a special situation where the user chooses to charge with the second type of charging pile. At this time, the total output power of all idle power modules in the first type of charging pile is less than the charging demand power of the vehicle. In order to meet the user's charging needs, all idle power modules can be used as M target power modules, that is, all available idle power modules are used to charge the device first, giving priority to meeting the user's charging requirements.

[0177] In one implementation, in the process of using all available idle power modules to charge the device, when there is a new released power module, the power module is called to charge the vehicle.

[0178] Specifically, during the vehicle charging process, a new idle power module will be released in the first type of charging pile when the device is in the power reduction stage. If a released power module is detected, a prompt message, such as a power delivery prompt message, is output to the target device. For example, a message "There is an existing released power module, please confirm whether to increase the charging power" can be sent to the vehicle terminal. If the user selects yes on the vehicle terminal, the local scheduling center determines that it has received confirmation information from the target device regarding the power delivery prompt message. At this time, the target charging pile is controlled to call the released power module, that is, to output the electric energy of the released power module to the vehicle. If the user selects no on the vehicle terminal, it is considered that the user does not want to increase the charging power, and at this time, it is prohibited to use the released power module to charge the vehicle.

[0179] It should be noted that the user can also choose automatic delivery on the vehicle terminal, that is, when there is a released power module, the charging pile is directly controlled to call the released power module to charge the vehicle without asking the user, so as to increase the vehicle charging power.

[0180] It should be noted that if after calling the released power module, the sum of the output powers of the power modules called by the target charging pile is not less than the charging power required by the target device, there is no need to call a new released power module at this time, and the monitoring operation of the released power module can be stopped. If, after calling the released power module, the charging power required by the target device is still not met, the power module release monitoring operation can be continued at this time. When there is a new released power module, the above-mentioned prompt information output operation is performed, and it is performed sequentially until the power module release monitoring operation is stopped when the charging power required by the target device is met.

[0181] In this embodiment, when the local dispatching center detects that other charging piles in the charging station have released power module information, it will deliver the power information to the user terminal or vehicle terminal using the target charging pile. The user can deliver power according to actual needs or set it to automatic delivery. After receiving the user's selection, the local dispatching center performs power switching to increase the vehicle charging power. At this time, due to the increase in charging power, the vehicle charging time will be shortened.

[0182] In another implementation of the present application, after determining the target charging pile and the target power module, the target power module and the target charging pile can also be locked so that the target power module and the target charging pile only provide power to the target device at the same time, thereby avoiding the situation where the same power module and the same charging pile are occupied by two vehicles at the same time.

[0183] In another implementation of the present application, after determining the target power module, the target charging pile can be controlled to call M target power modules to output electrical energy to charge the target device. Figure 3 As shown, since the first type charging pile and the second type charging pile are connected via a power output line, the power output line can be used for power transmission.

[0184] Specifically, the M target power modules may be controlled to be connected to the target charging pile, so that the target charging pile calls the M target power modules and charges the target device through the electric energy output by the power output line.

[0185] In order to improve the reliability of connectivity, switches may be provided on the first type of charging pile and the second type of charging pile, and connectivity and non-connectivity between the first type of charging pile and the second type of charging pile may be achieved by controlling the on and off of the switches.

[0186] like Figure 7 As shown, the first type of charging pile is internally provided with a main control and a power module, and the main control may be the above-mentioned TCU. The second type of charging pile is internally provided with a main control, and each main control may communicate through a switch.

[0187] A DC contactor is provided between the first type charging pile and the second type charging pile, and the DC contactor includes a plurality of single-pole single-throw switches, such as CB1, CB2 and CB3. The number of switches is the same as the number of power modules inside the first type charging pile, that is, the power output line of the power module inside the first type charging pile is connected to the power input line of the second type charging pile through the corresponding switch in the DC contactor.

[0188] The power input line inside the second type of charging pile is aggregated into a power output line, which is connected to the gun line through a contactor. The gun line can be connected to the charging gun, and the charging gun can be inserted into the vehicle charging port to charge the vehicle.

[0189] like Figure 8As shown, the 7# charging pile is the first type of charging pile, and the 8# charging pile is the second type of charging pile. When charging with the 8# charging pile, a power query request will be sent to the local scheduling center. At this time, the 7# charging pile is charging, and the charging equipment is in the power reduction stage. Since it is in the power reduction stage, not all power modules in the 7# charging pile are working, so the 7# charging pile can be called. In the 7# charging pile, the 2#, 4#, and 6# power modules are in the power output state, that is, they are currently working. The 1#, 3#, and 5# power modules are in the idle state. At this time, the local scheduling center can send a power scheduling instruction to the 7# charging pile, and the use identification of the 1#, 3#, and 5# power modules is updated to the occupied or locked state and the status information is uploaded to the local scheduling center. Finally, the CB1, CB2, and CB3 switches in the DC contactor are closed, and the 1#, 3#, and 5# power modules begin to output charging power to the 8# charging pile, and the vehicle begins to charge with the 8# charging pile.

[0190] From the above, it can be seen that power modules 1#, 3#, and 5# are the target power modules in the embodiment of the present application. The target switch between the target power module and the target charging pile (the target switch is a switch located inside the DC contactor, specifically the above-mentioned CB1, CB2, and CB3 switches) is closed so that the electric energy of the target power module is output to the target charging pile through the power output line where the target switch is located. The target charging pile uses a virtual power module to aggregate the power output of power modules 1#, 3#, and 5#, and charges the vehicle.

[0191] In another implementation of the present application, after the target charging pile is controlled to call the M target power modules, during the vehicle charging process, if the vehicle is fully charged, the charging operation needs to be stopped. Specifically, when the target charging pile detects that charging is completed (such as the vehicle is fully charged or the vehicle charging time reaches the time set by the user), it sends a stop charging request to the local scheduling center. The local scheduling center receives the stop charging request sent by the target charging pile, responds to the stop charging request, and sends a power stop output instruction to the first type of charging pile corresponding to the target power module, that is, notifies the first type of charging pile to stop the power output of the target power module, and controls the target charging pile to stop calling the M target power modules. Among them, controlling the target charging pile to stop calling the M target power modules can be: disconnecting the above-mentioned target switch that has been closed in the DC contactor, and finally turning off the power output of the second type of charging pile.

[0192] In this embodiment, after charging is completed, the local dispatching center receives a request to stop charging from the charging pile, and then recycles the power module and stops power output to stop charging the vehicle. After the charging gun is unplugged from the vehicle charging port, other vehicles can be charged. When charging other vehicles, the above control operation is repeated.

[0193] Based on the above-mentioned embodiment of the charging control method, another embodiment of the present application provides a charging control device, wherein the charging piles provided in the charging station include a first type of charging pile and a second type of charging pile, and the second type of charging pile is not equipped with a power module for providing electric energy.

[0211] In one implementation, the power determination module includes:

[0212] The fifth determination submodule is used to determine the target power module from the idle power module queue according to the arrangement order until the charging requirement power is met, wherein the idle power module queue includes all the idle power modules, and the idle power modules in the idle power module queue are sorted according to health or idle time.

[0213] In one implementation, the power determination module includes:

[0214] A data acquisition submodule, used to acquire the operation information of the charging pile where each of the idle power modules is located;

[0215] The sixth determination submodule is used for determining the M target power modules from the idle power modules in the non-operating charging piles if the operation information of the charging pile where the idle power module is located indicates that there is a non-operating charging pile.
