The controller divides multiple charging ports into a first group and a second group based on multiple actual charging powers. Among them, the charging ports belonging to the first group may have a greater demand for charging time than the charging ports belonging to the second group. Therefore, the controller adjusts the charging power of the charging ports belonging to the first group. Among them, the greater the power of the actual charging power, the less the power reduced during the corresponding adjustment; the controller adjusts the charging power of the charging ports belonging to the second group. Among them, the smaller the power of the actual charging power, the less the power reduced during the corresponding adjustment. The regulation process has less impact on vehicles with a greater demand for time.

Description

[0001] This application relates to the field of charging technology, and in particular, to an orderly charging control method and a charging pile. Background Art

[0002] The development of charging piles can be traced back to the early days of the birth of electric vehicles. However, it was not until recent years that, with the rapid growth of the electric vehicle market and the continuous promotion of policies, the charging pile industry has witnessed an explosive growth. From the initial sporadic distribution to the current dense network, charging piles have become an important part of urban infrastructure.

[0003] During the charging process of a charging pile, there is generally a certain limit on its total power. Charging can be carried out safely below the rated total power. However, the loss on the charging pile side during charging also changes with the increase in the total power. Generally speaking, the actual charging efficiency on the charging pile side decreases as the total power increases. Therefore, when the charging power of the charging pile is limited as low as possible compared to the rated total power, the efficiency of the charging pile is high.

[0004] During the regulation process of a charging pile, directly reducing the charging power of each charging port may lead to an extended charging time, reducing the user experience of users who have requirements for charging time. At the same time, directly reducing the power of all ports easily causes vehicles in trickle charging to not meet the minimum power requirement for charging. Summary of the Invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0073] Figure 1 It is a schematic flowchart of an orderly charging control method proposed in an embodiment of this application. DETAILED DESCRIPTION OF THE EMBODIMENTS

[0074] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0075] An embodiment of this application proposes an orderly charging control method, which is applicable to a charging pile. The charging pile includes multiple charging ports and a controller. The method is applicable to the controller. Please refer to Figure 1 , and the method includes the following steps:

[0076] S101: The controller obtains the current total power of multiple charging ports and determines whether to optimize the power of the charging pile based on the total power.

[0077] It can be understood that for charging devices in the prior art, such as charging piles or charging pile groups, multiple ports can support multiple vehicles to charge simultaneously. In this embodiment, a multi-port charging pile is taken as an example. Of course, in some other embodiments, it can also be multiple charging piles and corresponding charging pile controllers.

[0078] Exemplarily, the controller obtains the current total power of multiple charging ports, compares the current total power with a preset value. If the current total power is greater than the preset value, it determines to optimize the power of the charging pile and obtains the optimized power, where the optimized power is the difference between the current total power of the multiple charging ports and the target value.

[0079] For the charging devices in the prior art, during the charging process, there are generally certain limitations on their total power. Charging can be safely carried out below the rated total power. However, the losses on the charging pile side during charging also change with the increase of the total power. Generally speaking, the actual charging efficiency on the charging pile side decreases with the increase of the total power. Therefore, when the charging power of the charging pile is limited as low as possible compared to the rated total power, the efficiency of the charging pile is high. In this embodiment, the controller obtains the current total power of multiple charging ports and determines whether to optimize the power of the charging pile based on the total power. Exemplarily, it can be determined whether the current total power is greater than a preset threshold, and this threshold can be determined manually or by other means, which is not limited here. In some other embodiments, there can also be other ways to determine whether to optimize, such as combining the actual charging time length and fully charging within the rated time, adaptively adjusting the total power of the charging pile to make it reach the best charging power under qualified conditions.

[0080] S102: If the controller determines to optimize the power, the controller obtains the corresponding multiple actual charging powers of the multiple charging ports.

[0081] It can be understood that after determining that optimization can be carried out, the controller can optimize the charging of each port in combination with the actual charging power of each charging port. In some other embodiments, it can be a group controller that optimizes each charging pile.

[0082] S103: The controller divides the multiple charging ports into a first group and a second group based on the multiple actual charging powers, where the average value of the actual charging powers corresponding to the charging ports belonging to the first group is greater than the average value of the actual charging powers corresponding to the charging ports belonging to the second group.

[0083] Specifically, in this embodiment, after the controller determines that the charging power needs to be optimized, that is, the total power of the entire charging system needs to be reduced, it can adopt a grouped control method to control multiple actual charging powers. Specifically, in combination with the use process of the charging pile, when an electric vehicle is charging, those with a larger charging power are often vehicles with a relatively low current battery level in the vehicle battery system, and it is a process of fast charging the vehicle battery. At this time, for the vehicle user, it may be a user who has just arrived at the charging station and is waiting to use the vehicle, and has certain requirements for the charging time. Therefore, it is not necessary to fully charge the vehicle, but the vehicle needs to be charged to a state where it can be used sufficiently. In contrast, for the charging port with a smaller charging power, generally after the vehicle battery is fully charged to a certain extent, the vehicle charging management module adopts a trickle charging method to improve the battery life of the vehicle. At this time, for the user, when the vehicle is connected to the charging pile, the charging time required can be roughly obtained, and the user may not be next to the vehicle, so the charging demand for the vehicle is relatively low. Combining the actual use process, that is, the charging ports belonging to the first group are the ports with a faster charging speed and may have a shorter demand for charging time, and the charging ports belonging to the second group are the ports with a slower charging speed and may have a lower demand for time than the charging ports in the first group. Therefore, the charging power of multiple charging ports can be adjusted according to the actual needs, which can improve the charging efficiency of the charging pile while meeting the needs as much as possible.

[0084] For the basis of dividing the first group and the second group, it can be divided according to a preset value, such as the value when a conventional vehicle is in trickle charging, or it can be divided in other ways, which is not limited here.

[0085] S104: The controller adjusts the charging power of the charging ports belonging to the first group, where the greater the power of the actual charging power, the less the power reduced during the corresponding adjustment.

[0086] In this embodiment, the controller adjusts the charging power of the charging ports belonging to the first group, where the greater the power of the actual charging power, the less the power reduced during the corresponding adjustment. It can be understood that since the charging ports belonging to the first group may have a shorter time requirement, during the charging process, for the charging ports with a larger charging power, that is, the ports with a relatively low remaining battery level, the value reduced when reducing their charging power is also less.

[0087] Specifically, in this embodiment, step S104 may include the following steps:

[0088] S1041: The controller obtains the first total power of the charging ports belonging to the first group and the second total power of the charging ports belonging to the second group.

[0089] It can be understood that by directly obtaining the actual power of each charging port through the controller, the first total power of the charging ports belonging to the first group and the second total power of the charging ports belonging to the second group can be obtained by successive addition.

[0090] S1042: The controller divides the optimized power into a first optimized power and a second optimized power based on the ratio relationship between the first total power and the second total power.

[0091] It can be understood that for the first optimized power, that is, the power that needs to be reduced from the first total power of the charging ports belonging to the first group. For the second optimized power, that is, the power that needs to be reduced from the second total power of the charging ports belonging to the second group. The total power belonging to the first group must be greater than the total power belonging to the second group.

[0092] Since the ports belonging to the first group may have higher requirements for time, therefore, during the actual regulation process, when optimizing the charging ports of the first group, the reduced value is lower than that when optimizing the charging ports of the second group to ensure that the charging time of the ports in the first group is not greatly affected at this time.

[0093] Specifically, in this embodiment, the ratio of time to the reduced values of the first total power and the second total power can be determined according to the ratio of the first total power to the second total power.

[0094] Specifically, in this embodiment, it satisfies:

[0095] Satisfies:

[0096] Wherein, is the first total power, is the second total power, is the first optimized power, is the second optimized power.

[0097] It can be understood that at this time, the ratio of the first total power to the second total power is inversely proportional to the ratio of the first optimized power to the second optimized power. Of course, in some other embodiments, the values that need to be optimized can also be determined based on other methods, which are not limited herein.

[0098] S1043: The controller optimizes the first total power based on the first optimized power so that the reduced value of the first total power is the same as the value of the first optimized power.

[0099] It can be understood that the optimized value of the first total power is the value of the first optimized power. For how to reasonably distribute the first optimized value to each charging port belonging to the first group, in this embodiment, the following steps can be included:

[0100] S201: The controller sorts the actual charging powers corresponding to multiple charging ports belonging to the first group to obtain a first sequence.

[0101] It can be understood that, by way of example, in this embodiment, multiple charging ports belonging to the first group can be arranged in ascending order. That is, the larger the charging power of a port, the greater the possibility of its demand for time. Therefore, when adjusting it, the reduction amount of its power is also as low as possible. Of course, the arrangement method can also be from large to small or in a normal distribution, which is not limited herein.

[0102] S202: The controller arranges multiple first sub-optimized powers based on the correspondence between the first sequence and the actual charging powers and the multiple first sub-optimized powers to obtain a second sequence, and reverses the second sequence to obtain a third sequence.

[0103] It can be understood that based on the correspondence, a sequence of multiple first sub-optimized powers can be obtained. Then, by reversing this sequence, a sequence from large to small can be obtained.

[0104] S202: Combine the first sequence and the third sequence so that the actual charging powers corresponding to the charging ports of the first group are adjusted according to the corresponding first sub-optimized powers.

[0105] It can be understood that combining the first sequence and the third sequence means that for charging ports with smaller actual charging powers, the demand for time may be lower. Therefore, during optimization, the corresponding third sequence, that is, the value of the corresponding first sub-optimized power, is larger. On the contrary, for charging ports with larger actual charging powers, the demand for time may be higher. Therefore, during optimization, the corresponding third sequence, that is, the value of the corresponding first sub-optimized power, is smaller.

[0106] S105: The controller adjusts the charging powers of the charging ports belonging to the second group, where the smaller the actual charging power, the less the power reduced during the corresponding adjustment.

[0107] It can be understood that for the charging ports belonging to the second group, these ports with smaller powers, during the optimization process, since all the charging ports of the second group have lower requirements for time, therefore, during the adjustment process, the entire charging ports belonging to the second group can be adjusted according to the actual total adjustment ratio. The adjustment process is relatively simple and can avoid the adjusted power being less than the minimum required power of the vehicle.

[0108] It can be understood that in this embodiment, the controller optimizes the second total power based on the second optimized power so that the decrease value of the second total power is the same as the value of the second optimized power.

[0109] For a specific regulation process, since it is regulated proportionally, as an implementation method, it can be carried out in the following manner:

[0110] The controller can obtain multiple second charging powers and obtain the ratio relationship between the multiple second charging powers and the second total power;

[0111] Based on the ratio relationship between multiple actual charging powers and the second total power, the controller divides the second optimized power into multiple second sub-optimized powers and obtains the corresponding relationship between the multiple second charging powers and the multiple second sub-optimized powers;

[0112] Based on the corresponding relationship between the multiple second charging powers and the multiple second sub-optimized powers, and the second sub-optimized powers, the controller optimizes each second charging port belonging to the second group, where the larger the value of the second sub-optimized power, the smaller the corresponding second charging power.

[0113] Specifically, the controller sorts the actual charging powers corresponding to multiple charging ports belonging to the second group to obtain a fourth sequence;

[0114] Based on the fourth sequence and the corresponding relationship between the actual charging power and the multiple second sub-optimized powers, the controller arranges the multiple second sub-optimized powers to obtain a fifth sequence;

[0115] Combine the fourth sequence with the fifth sequence so that the actual charging power corresponding to the charging ports of the second group is regulated according to the corresponding second sub-optimized power.

[0116] It can be understood that through the above steps, it is possible to regulate the power of the charging ports belonging to the second group proportionally, so that the decrease value of the second total power is the same as the value of the second optimized power.

[0117] An orderly charging control method proposed in this application. The controller divides multiple charging ports into a first group and a second group based on multiple actual charging powers. Among them, the charging ports belonging to the first group may have a greater demand for charging time than the charging ports belonging to the second group. Therefore, the controller adjusts the charging power of the charging ports belonging to the first group. Among them, the greater the power of the actual charging power, the less the power is reduced during the corresponding adjustment; the controller adjusts the charging power of the charging ports belonging to the second group. Among them, the smaller the power of the actual charging power, the less the power is reduced during the corresponding adjustment. An orderly charging control method proposed in this application, when reducing the total power of the entire charging system, when regulating the charging ports with a higher demand for charging time, the value of the charging power reduced for the ports with a higher demand for charging time is lower, and the impact on the charging time is lower. When regulating the charging ports with a lower demand for charging time, the reduction value for the charging ports with a lower charging power among them is lower, and the problem that the power after regulation is lower than the minimum charging demand of the vehicle is minimized as much as possible.

[0118] Based on the same inventive concept, an embodiment of this application proposes a charging pile. The charging pile includes multiple charging ports and a controller, and the charging pile is configured to:

[0119] The controller obtains the current total power of multiple charging ports and determines whether to optimize the power of the charging pile based on the total power;

[0120] If the controller determines to optimize the power, the controller obtains the multiple actual charging powers corresponding to the multiple charging ports;

[0121] The controller divides the multiple charging ports into a first group and a second group based on the multiple actual charging powers. Among them, the average value of the actual charging powers corresponding to the charging ports belonging to the first group is greater than the average value of the actual charging powers corresponding to the charging ports belonging to the second group;

[0122] The controller adjusts the charging power of the charging ports belonging to the first group. Among them, the greater the power of the actual charging power, the less the power is reduced during the corresponding adjustment;

[0123] The controller adjusts the charging power of the charging ports belonging to the second group. Among them, the smaller the power of the actual charging power, the less the power is reduced during the corresponding adjustment.

[0124] In some feasible embodiments, the controller obtains the current total power of multiple charging ports and determines whether to optimize the power of the charging pile based on the total power, including:

[0125] The controller obtains the current total power of multiple charging ports, compares the current total power with a preset value. If the current total power is greater than the preset value, it determines to optimize the power of the charging pile and obtains the optimized power, where the optimized power is the difference between the current total power of the multiple charging ports and the target value.
