[0045] The terms "first", "second", "third", "fourth", etc. (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that the data used in this way can be interchangeable where appropriate, so that the embodiments described herein can be implemented in a sequence other than that illustrated or described herein. In addition, the terms "including" and "having" and any variations thereof are intended to cover non-exclusive inclusions. For example, a process, method, system, product or device that includes a series of steps or units is not necessarily limited to those steps or units that are clearly listed, but may include other steps or units that are not clearly listed or that are inherent to these processes, methods, products or devices. The technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the embodiments described are only part of the embodiments of the present application, not all of the embodiments.

[0046] The first aspect of the embodiment of the present application proposes a split DC charging method, such as Figure 1 As shown, the method may include:

[0047] Step S110: obtaining the vehicle model of the vehicle to be charged entering the charging station, wherein the charging station includes multiple charging piles, and each charging pile is used to distribute power to multiple charging piles under its jurisdiction.

[0048] Specifically, depending on the scale and application scenarios of a charging station, it can include multiple charging stacks. These stacks can include a main power cabinet and multiple charging piles, which can flexibly distribute the charging power of multiple charging piles. The charging station can obtain the vehicle model of incoming vehicles through various methods, such as using a camera to capture the license plate and querying the specific model based on the license plate, or by identifying the vehicle model by identifying registered members of the charging station.

[0049] Step S120: Determine the required charging power of the vehicle to be charged based on the vehicle model.

[0050] Specifically, different brands, different models, and different types of vehicles to be charged correspond to different applicable charging powers. The applicable charging power can be obtained based on analysis of parameters such as the charging time and charging current of the electric vehicle. The above-mentioned applicable charging power is the charging demand power.

[0051] Step S130 , recommending a charging pile for the vehicle to be charged based on the required charging power, the current charging power of the charging piles in use under each charging pile, and the average allocated power of the charging piles, so as to charge the vehicle to be charged.

[0052] What can be explained is that the charging stack adopts a flexible power distribution method, and the charging power among the multiple charging piles under its jurisdiction can be dynamically distributed. The current power of the charging piles in use of each charging stack is different, and each charging stack distributes power to multiple charging piles differently. In the same charging station, multiple charging stacks have the same specifications, so each charging stack has the same average power. This further explains that the current charging power of the charging piles in use under each charging stack can be greater than or less than the average distributed power of the charging stack.

[0053] Specifically, the charging power requirement of the vehicle to be charged is compared with the average power of the charging stack. If the charging power requirement is greater than the average power of the charging stack, a charging stack with a current charging power less than the average power of the charging stack is selected from multiple charging stacks, and the charging piles under this charging stack are recommended to the vehicle to be charged. If the charging power requirement is less than the average power of the charging stack, a charging stack with a current charging power greater than the average power of the charging stack is selected from multiple charging stacks, and the charging piles under this charging stack are recommended to the vehicle to be charged.

[0054] In summary, this solution determines the charging power requirement of the vehicle to be charged by obtaining the vehicle model, and compares the charging power requirement of the vehicle to be charged, the current charging power of the charging piles in use under the charging stack, and the average allocated power of the charging stack, so as to understand the number of charging piles in use under each charging stack whose current charging power is higher than the average allocated power and the number of charging piles lower than the average allocated power. In this way, it can be determined whether the power utilization rate of each charging stack in the charging station is low or the charging pile utilization rate is low. Therefore, based on the high and low relationship between the charging power requirement of the vehicle to be charged and the average allocated power, a charging stack is selected for the vehicle to be charged, and the charging piles under the above charging stack are recommended to the above vehicle to be charged, so as to use the vehicle to be charged to balance the current power utilization rate of the charging stack and the charging pile utilization rate. The problem of load distribution between multiple charging stacks is optimized, and the waste or insufficient power resources of each charging stack is avoided.

[0055] In a feasible embodiment, determining a charging pile for the vehicle to be charged based on the required charging power, the current charging power of each of the charging piles in use under the charging pile, and the average allocated power of the charging pile includes:

[0056] Obtain the relationship between the current charging power of the charging piles in use under each charging stack and the above-mentioned average distributed power;

[0057] If, among the current charging powers of the charging piles in use under the same charging stack, the number of charging piles with a higher average power than the above average distribution power is greater than the number of charging piles with a lower average power distribution power, the charging stack is determined to be the first charging stack;

[0058] If, among the current charging powers of the charging piles in use under the same charging stack, the number of charging piles with higher than the average allocated power is less than the number of charging piles with lower than the average allocated power, the charging stack is determined to be the second charging stack;

[0059] When the required charging power is lower than the average allocated power, a charging pile under the first charging pile is recommended for the vehicle to be charged;

[0060] In a case where the required charging power is higher than the average allocated power, a charging pile under the second charging pile is recommended to the vehicle to be charged.

[0061] Specifically, the number of in-use charging piles under each charging stack and the current charging power of the in-use charging piles under each charging stack are obtained. Based on this information, the number of in-use charging piles with higher than average power allocation and the number of in-use charging piles with lower than average power allocation under each charging stack are obtained. A charging stack in which the number of in-use charging piles with higher than average power allocation is greater than the number of in-use charging piles with lower than average power allocation is referred to as a first charging stack, and a charging stack in which the number of in-use charging piles with higher than average power allocation is less than the number of in-use charging piles with lower than average power allocation is referred to as a second charging stack.

[0062] Furthermore, when the charging power demand of the vehicle to be charged is lower than the average allocated power, the vehicle to be charged is recommended to be charged at the charging pile under the first charging pile. When the charging power demand of the vehicle to be charged is higher than the average allocated power, the vehicle to be charged is recommended to be charged at the charging pile under the second charging pile.

[0063] For example, a charging station includes four charging piles, designated A, B, C, and D. Each charging pile contains six charging piles, with an average power distribution of 200 kW. The charging power demanded by the vehicle to be charged is 220 kW. Charging pile A has four charging piles in use, three of which are greater than the average power distribution, and one is less than the average power distribution. Charging pile A is designated as the first charging pile. Charging pile B has three charging piles in use, two of which are greater than the average power distribution, and one is less than the average power distribution. Charging pile B is designated as the first charging pile. Charging pile C has five charging piles in use, two of which are greater than the average power distribution, and three are less than the average power distribution. Charging pile C is designated as the second charging pile. Charging pile D has one charging pile in use, and this charging pile has a power distribution greater than the average power distribution. Charging pile D is designated as the first charging pile. Because the charging power demanded by the vehicle to be charged is 220 kW, which is greater than the average power distribution, the vehicle to be charged can charge at the charging piles in the second charging pile, which is the charging pile under charging pile C.

[0064] In summary, this solution determines the number of active charging piles under different charging stacks whose current charging power exceeds or falls below the average allocated power. Based on this number, it determines the first and second charging piles. Then, based on the relationship between the charging power demand of the vehicle to be charged and the average allocated power, it recommends the charging pile for the vehicle to be charged. This solution optimizes load distribution among multiple charging piles and avoids wasted or insufficient power resources at each charging pile.

[0065] In a feasible embodiment, when there are more than or equal to two vehicles to be charged, the charging power requirement of each vehicle to be charged is determined based on the vehicle model;

[0066] Associating a first vehicle to be charged with a second vehicle to be charged, wherein the first vehicle to be charged is a vehicle to be charged whose charging power demand is higher than the average allocated power of the charging stack, and the second vehicle to be charged is a vehicle to be charged whose charging power demand is lower than the average allocated power of the charging stack, and in each group of associated vehicles to be charged, the number of the first vehicles to be charged is the same as the number of the second vehicles to be charged;

[0067] The vehicles to be charged that are associated as a group are recommended to the charging piles under the same charging pile.

[0068] Specifically, when the above-mentioned vehicles to be charged are greater than or equal to two vehicles, the charging power requirement of each vehicle is determined based on the vehicle model. The above-mentioned vehicles to be charged include vehicles to be charged with a charging power requirement greater than the average allocated power and vehicles to be charged with a charging power requirement less than the average allocated power. The vehicles to be charged with a charging power requirement greater than the average allocated power and the vehicles to be charged with a charging power requirement less than the average allocated power are associated into a group, and the above-mentioned vehicles to be charged associated into a group are recommended to the charging piles under the same charging stack.

[0069] Exemplarily, the above-mentioned vehicles to be charged include three vehicles, namely A, B, and C, among which the charging power requirements of A and C are greater than the average allocated power, and the charging power requirement of B is less than the average allocated power. This method can divide A and B into a group, and recommend vehicles A and B to be charged to the charging piles under the same charging stack for charging, and vehicle C can be recommended to the charging pile under the above-mentioned second charging stack for charging.

[0070] In summary, this solution groups vehicles to be charged whose charging power requirements are greater than the average allocated power and whose charging power requirements are less than the average allocated power, and recommends these vehicles to the charging piles under the same charging pile for charging. This optimizes the distribution of multiple loads among multiple charging piles and avoids waste or insufficient power resources in each charging pile.

[0071] In a feasible embodiment, the identification and / or location of the recommended charging pile is sent to the vehicle terminal of the corresponding vehicle to be charged and / or the mobile terminal of the user.

[0072] Specifically, a charging station has multiple charging piles, each of which has multiple charging posts. The charging posts are relatively scattered, and the charging posts recommended for vehicles to be charged are not necessarily the same each time. It is difficult for users of the vehicles to be charged to find the charging posts they need to go to in a short time.

[0073] Exemplarily, the server of the charging station can send the identification and / or location of the charging pile recommended for the vehicle to be charged to the above-mentioned vehicle to be charged. The vehicle to be charged can use the vehicle's smart terminal and / or the mobile terminal of its user. Specifically, it can obtain the service public account of the charging station through the user of the vehicle to be charged or register as a charging station member to obtain the identification and / or location of the recommended charging pile.

[0074] In summary, this solution sends the identification and / or location of the recommended charging pile for the vehicle to be charged to the charging vehicle, which reduces the time it takes for the vehicle to be charged to find the recommended charging pile, speeds up the charging cycle of the vehicle at the charging station, and improves the working efficiency of the charging station.

[0075] In a feasible embodiment, the vehicle identification information of the vehicle to be charged that enters the charging station earlier among the vehicles to be charged that are associated as a group is sent to the vehicle terminals of other vehicles to be charged in the same group and / or the mobile terminals of the users to whom they belong; and / or,

[0076] The vehicle identification information of the vehicles to be charged that are associated as a group is shared with the vehicle terminals of all the vehicles to be charged in the same group and / or the mobile terminals of the users to whom they belong.

[0077] Specifically, the vehicles to be charged, which are grouped together, are sequentially assigned to the charging station. These vehicles are recommended to charge at the same charging piles, assuming that the vehicles are heading to similar locations. The vehicle identification information may include license plate, vehicle color, vehicle type, and vehicle brand.

[0078] Exemplarily, the vehicles to be charged that are associated as a group include four vehicles A, B, C, and D. The recommended charging pile belongs to charging pile E. Vehicle A enters the charging station first, and the vehicle identification information of vehicle A is sent to the vehicle end of the above-mentioned three vehicles to be charged B, C, and D and / or the mobile terminal of the user to whom it belongs, and the vehicle identification information of any vehicle B, C, and D is shared with the vehicle end of the other three vehicles to be charged and / or the mobile terminal of the user to whom it belongs. The above-mentioned four vehicles to be charged A, B, C, and D can follow the previous vehicle to be charged to determine the position of charging pile E, which reduces the time for multiple vehicles to be charged to find the recommended charging pile and improves the working efficiency of the charging station.

[0079] In another example, the vehicles to be charged that are associated as a group include four vehicles A, B, C, and D. The recommended charging pile belongs to charging stack E. Vehicle A enters the charging station first and sends the vehicle identification information of Vehicle A to the vehicle terminals of the above-mentioned three vehicles to be charged, B, C, and D, and / or the mobile terminals of their users. Vehicle A enters the charging station first and can determine the location of charging stack E first. Other vehicles can follow Vehicle A to determine charging stack E based on the identification information of Vehicle A.

[0080] In another example, the vehicles to be charged that are associated as a group include four vehicles A, B, C, and D, and the charging pile to which the recommended charging station belongs is E. The vehicle identification information of any vehicle is shared with the vehicle terminals of the other three vehicles to be charged and / or the mobile terminals of the users to whom they belong, so that any vehicle among the vehicles to be charged that are associated as a group can determine the location of the charging pile E by following the associated vehicles within a certain range.

[0081] In summary, this solution shares the vehicle identification information of the vehicles to be charged that are associated as a group with other vehicles to be charged in the same group, so that the vehicles to be charged that are recommended to the charging piles under the same charging pile can quickly determine the location of the recommended charging piles based on the vehicle identification information of the preceding vehicles, thereby reducing the time for multiple vehicles to be charged to search for the recommended charging piles, speeding up the charging cycle of vehicles at the charging station, and improving the working efficiency of the charging station.

[0082] In a feasible embodiment, when all charging piles of the charging station are in use and the amount of electricity to be charged is greater than a preset amount of electricity, navigation information and the current remaining electricity of the currently charging vehicle are obtained, wherein the navigation information includes destination information;

[0083] determining a theoretical expected remaining power based on the vehicle model, destination information, and location information of the charging station of the currently charging vehicle;

[0084] Sending a stop charging request to the target currently charging vehicle whose current remaining power is greater than the theoretical expected remaining power;

[0085] The charging pile used by the target current charging vehicle is recommended to the target vehicle to be charged.

[0086] Specifically, when all the charging piles under the above-mentioned charging station are in use, that is, there are no idle charging piles at present, the above-mentioned amount of power to be charged is the amount of power required to fully charge the current charging vehicle, the above-mentioned preset power is set for the charging pile, which can be 15 kWh, and the above-mentioned current remaining power is the power of the current charging vehicle when charging. For example, if the maximum power of the current charging vehicle is 70 kWh, and the power during charging is 30 kWh, that is, the current remaining power is 30 kWh, and the above-mentioned amount of power to be charged is 40 kWh, then the above-mentioned amount of power to be charged is greater than the above-mentioned preset power. At this time, the destination information of the on-board navigation of the current charging vehicle or the navigation software of the user's mobile terminal to which the current charging vehicle belongs and the current remaining power of the current charging vehicle are obtained.

[0087] The theoretical expected remaining power is determined based on the vehicle model of the currently charging vehicle, the destination information, and the location of the charging station. It can be understood as the minimum amount of power required for the currently charging vehicle to travel from the charging station to the destination.

[0088] A stop charging request is sent to the target currently charging vehicle whose current remaining power is greater than the above theoretical expected remaining power. The charging request can be implemented through the mobile terminal of the user of the above currently charging vehicle or the sound reminder of the charging pile, etc., which is not limited here.

[0089] The charging pile currently being used by the currently charging vehicle is recommended to the vehicle to be charged. The vehicle to be charged can be charged when the current remaining power of the currently charging vehicle is greater than the theoretical expected remaining power.

[0090] For ease of understanding, the embodiment of the present application gives a specific example. The currently charging vehicle is A, the vehicle to be charged is B, and the location information of the charging station is C. At this time, the charging piles under all the charging piles of the charging station are in working condition, and car A is also charging at one of the charging piles. The full power of car A is 70 kWh, the preset power set by the charging station is 15 kWh, the current remaining power of car A is 30 kWh, and the power to be charged is 40 kWh. It can be obtained that the power to be charged of car A is greater than the preset power. At this time, the navigation destination information of car A is D. According to the distance between C and D and the specific model of car A, the minimum power required for car A to travel from the charging station to the destination, that is, the theoretical expected remaining power, such as 55 kWh, can be obtained. As the charging pile charges car A, when the current remaining power of car A is greater than the theoretical expected remaining power, such as the current remaining power of car A is 56 kWh, a stop charging request is sent to car A. Car A accepts the request and stops charging, preparing to leave the charging station and head to the destination, and recommends the charging pile D used by car A to vehicle B to be charged.

[0091] In summary, when the charging station is busy, this solution obtains the relationship between the current remaining power of the currently charging vehicle and the model and destination of the currently charging vehicle, and sends a stop charging request to the currently charging vehicle, so that the vehicle to be charged can use the charging pile used by the currently charging vehicle as soon as possible, reducing the waiting time of the vehicle to be charged when the charging station is busy and improving the working efficiency of the charging station.

[0092] In a feasible embodiment, the navigation information includes slope road information, and the slope road information includes slope road length and slope road angle.

[0093] The above method further includes:

[0094] determining a correction amount based on the vehicle model of the currently charging vehicle, the length of the sloped road surface, and the angle of the sloped road surface;

[0095] Correcting the theoretical expected remaining capacity based on the correction amount to determine a corrected expected remaining capacity;

[0096] Sending a stop charging request to a target currently charging vehicle whose current remaining power is greater than the corrected expected remaining power;

[0097] The charging pile used by the target current charging vehicle is recommended to the target vehicle to be charged.

[0098] Specifically, the navigation information of the currently charging vehicle includes the slope road surface information of the road section from the above-mentioned charging station to the above-mentioned destination. The slope road surface information includes the slope road surface length and the slope road surface angle. It can be expected that when the currently charging vehicle is going uphill, the longer the slope road surface and the larger the slope road surface angle, the more electricity is consumed. When the currently charging vehicle is going downhill, the longer the slope road surface and the larger the slope road surface angle, the less electricity is consumed.

[0099] Furthermore, a correction amount is determined based on the slope of the road section between the charging station and the destination. If the road section is primarily uphill, the correction amount is positive, appropriately increasing the theoretical expected remaining power. If the road section is primarily downhill, the correction amount is negative, appropriately decreasing the theoretical expected remaining power. The corrected expected remaining power is determined based on the above conditions.

[0100] When the current remaining power of the currently charging vehicle is greater than the corrected expected remaining power, a stop charging request is sent to the currently charging vehicle, and a charging pile used by the target currently charging vehicle is recommended to the vehicle to be charged.

[0101] In summary, this solution corrects the theoretical expected remaining power by obtaining slope road information, so that the power required by the current charging vehicle to travel from the charging station to the destination can be determined more accurately.

[0102] The second aspect of the embodiment of the present application provides a split-type DC charging device 20, such as Figure 2 As shown, the device includes:

[0103] An acquisition module 201 is configured to acquire the vehicle model of a vehicle entering a charging station, wherein the charging station includes multiple charging piles, each of which is configured to distribute power to multiple charging piles under its jurisdiction;
