Description

[0001] The present 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 electric vehicles. However, it was not until recent years that the charging pile industry ushered in explosive growth with the rapid growth of the electric vehicle market and the continuous promotion of policies. From the initial sporadic distribution to today's dense network, charging piles have become an important part of urban infrastructure.

[0003] The total power of the charging pile is generally limited during the charging process. Charging can be performed safely below the rated total power, but the loss on the charging pile side also changes 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, the efficiency of the charging pile is high when the charging power of the charging pile is limited to a level lower than the rated total power as much as possible.

[0004] In the process of regulation, the charging pile directly reduces the charging power of each charging port, which may extend the charging time and reduce the user experience of users who have demanding charging time. At the same time, directly reducing the power of all ports may easily make vehicles that are trickle charged fail to meet the minimum charging power requirement. Summary of the invention

BRIEF DESCRIPTION OF THE DRAWINGS

[0027] Figure 1 A schematic flow chart of an orderly charging control method proposed in an embodiment of the present application. DETAILED DESCRIPTION

[0028] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0029] The embodiment of the present application proposes an orderly charging control method applicable to a charging pile, the charging pile includes multiple charging ports and a controller, and the method is applicable to the controller, see Figure 1 , the method comprises the following steps: 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.

[0030] It is understandable that charging equipment in the prior art, such as a charging pile or a charging pile group, can simultaneously support multiple ports to charge multiple vehicles at the same time. In this embodiment, a multi-port charging pile is taken as an example. Of course, in other embodiments, there may also be multiple charging piles and corresponding charging pile controllers.

[0031] Exemplarily, the controller obtains the current total power of multiple charging ports, compares the current total power with a preset value, and if the current total power is greater than the preset value, determines to optimize the power of the charging pile and obtains the optimized power, wherein the optimized power is the difference between the current total power of multiple charging ports and the target value.

[0032] For the charging equipment in the prior art, there are generally certain restrictions on its total power during the charging process. Charging can be carried out safely under the rated total power, but the loss on the charging pile side during charging also changes 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, the efficiency of the charging pile is high when the charging power of the charging pile is limited to a lower level than the rated total power as much as possible. 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, which can be determined manually or in other ways, and 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, fully charging within the rated time, etc., to adaptively adjust the total power of the charging pile so that it reaches the optimal charging power when the conditions are met.

[0033] S102: If the controller determines to perform power optimization, the controller obtains multiple corresponding actual charging powers of multiple charging ports.

[0034] It is understandable that after determining that optimization is possible, the controller can optimize the charging of each port in combination with the actual charging power of each charging port. In other embodiments, the group controller can optimize each charging post.

[0035] S103: The controller divides the multiple charging ports into a first group and a second group based on the multiple actual charging powers, wherein an average value of the actual charging powers corresponding to the charging ports belonging to the first group is greater than an average value of the actual charging powers corresponding to the charging ports belonging to the second group.

[0036] 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 use a group control method to control multiple actual charging powers. Specifically, combined with the use of the charging pile, when charging an electric vehicle, the vehicle with a larger charging power is often a vehicle with a lower current battery power in the vehicle battery system, and the vehicle battery is fast charged. At this time, for the user of the vehicle, it may be a user who has just arrived at the charging station and is waiting to use the vehicle. There are certain requirements for the charging time. Therefore, there is no need to fully charge the vehicle, but the vehicle needs to be charged to a state sufficient for use. In contrast, the port with a smaller charging power is generally used after the vehicle battery is fully charged to a certain extent. In order to improve the battery life of the vehicle, the vehicle charging management module adopts a trickle charging method. At this time, for the user, when the vehicle is connected to the charging pile, the time required for charging is roughly obtained, and the person may no longer be next to the vehicle, so the charging demand for the vehicle is relatively low. Combined with the actual usage process, the charging ports belonging to the first group are ports with faster charging speeds and may require a shorter charging time, and the charging ports belonging to the second group are ports with slower charging speeds and may have a lower time requirement than the charging ports in the first group. Therefore, the charging power of multiple charging ports can be adjusted according to actual needs, so as to meet the needs as much as possible while improving the charging efficiency of the charging pile.

[0037] The basis for dividing the first group and the second group may be based on a preset value, such as the value of a conventional vehicle during trickle charging, or may be divided in other ways, which are not limited here.

[0038] S104: The controller adjusts the charging power of the charging ports belonging to the first group, wherein the greater the actual charging power is, the less the power is reduced during the corresponding adjustment.

[0039] In this embodiment, the controller adjusts the charging power of the charging ports belonging to the first group, wherein the greater the actual charging power, the less power is reduced during the corresponding adjustment. It is understandable 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 greater charging power, that is, the ports with lower battery remaining power, the value reduced when reducing their charging power during the adjustment process is smaller.

[0040] Specifically, in this embodiment, step S104 may include the following steps: S1041: The controller obtains a first total power of charging ports belonging to a first group and a second total power of charging ports belonging to a second group.

[0041] It can be understood that the actual power of each charging port is directly obtained through the controller, and 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 adding them one by one.

[0042] S1042: The controller divides the optimized power into a first optimized power and a second optimized power based on the ratio between the first total power and the second total power.

[0043] It can be understood that for the first optimized power, that is, the first total power of the charging ports belonging to the first group needs to be reduced. For the second optimized power, that is, the second total power of the charging ports belonging to the second group needs to be reduced. The total power belonging to the first group must be greater than the total power belonging to the second group.

[0044] Since the ports belonging to the first group may have higher requirements on time, therefore, in the actual regulation process, when optimizing the charging ports of the first group, the reduced value thereof is lower than the reduced value when optimizing the charging ports of the second group, to ensure that the charging time of the ports of the first group is not greatly affected at this time.

[0045] Specifically, in this embodiment, the ratio of time to the reduction value of the first total power and the second total power may be determined according to the ratio of the first total power to the second total power.

[0046] Specifically, in this embodiment, the following conditions are met: satisfy:

[0047] in, is the first total power, is the second total power, To optimize power first, Optimize power for the second.

[0048] It is understandable that 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 other embodiments, the value to be optimized may be determined based on other methods, which are not limited here.

[0049] S1043: The controller optimizes the first total power based on the first optimized power so that the first total power reduction value is the same as the value of the first optimized power.

[0050] It can be understood that the optimized value of the first total power is the value of the first optimized power. As to how to reasonably distribute the first optimized value to each charging port belonging to the first group, in this embodiment, the following steps may be included: S201: The controller sorts actual charging powers corresponding to multiple charging ports belonging to a first group to obtain a first sequence.

[0051] It can be understood that, for example, in this embodiment, multiple charging ports belonging to the first group can be arranged in order from small to large, that is, the larger the charging power of the port, the greater the possibility of its time demand. Therefore, when regulating it, the reduction in its power is as low as possible. Of course, the arrangement can also be from large to small or normal distribution, which is not limited here.

[0052] S202: Based on the correspondence between the first sequence, the actual charging power and the plurality of first sub-optimized powers, the controller arranges the plurality of first sub-optimized powers to obtain a second sequence, and reverses the second sequence to obtain a third sequence.

[0053] It can be understood that a plurality of sequences of first sub-optimization powers can be obtained based on the corresponding relationship, and then the sequence can be reversed to obtain a sequence from large to small.

[0054] S202: Combine the first sequence with the third sequence so that the actual charging power corresponding to the charging ports of the first group is regulated according to the corresponding first sub-optimal power.

[0055] It can be understood that the first sequence is combined with the third sequence, that is, the charging port with a smaller actual charging power may have a lower demand for time. Therefore, during optimization, the corresponding third sequence, that is, the corresponding first sub-optimization power value is larger. Conversely, the charging port with a larger actual charging power may have a higher demand for time. Therefore, during optimization, the corresponding third sequence, that is, the corresponding first sub-optimization power value is smaller.

[0056] S105: The controller adjusts the charging power of the charging ports belonging to the second group, wherein the smaller the actual charging power is, the smaller the power reduction during the corresponding adjustment is.

[0057] It can be understood that for the charging ports belonging to the second group, which are ports with lower power, during the optimization process, since all the charging ports in the second group have lower time requirements, during the regulation process, the entire charging ports belonging to the second group can be regulated according to the actual total regulation ratio. The regulation process is relatively simple and can avoid the adjusted power being less than the minimum required power of the vehicle.

[0058] It can be understood that, in this embodiment, the controller optimizes the second total power based on the second optimized power so that the second total power reduction value is the same as the value of the second optimized power.

[0059] As for the specific regulation process, since it is regulated in proportion, as an implementation method, it can be carried out in the following manner: The controller may obtain a plurality of second charging powers, and obtain a ratio relationship between the plurality of second charging powers and the second total power; The controller divides the second optimized power into a plurality of second sub-optimized powers based on a ratio relationship between the plurality of actual charging powers and the second total power, and obtains a correspondence relationship between the plurality of second charging powers and the plurality of second sub-optimized powers; The controller optimizes every two charging ports belonging to the second group based on the correspondence between the plurality of second charging powers and the plurality of second sub-optimized powers, and the second sub-optimized powers, wherein a larger second sub-optimized power corresponds to a smaller second charging power.

[0060] Specifically, the controller sorts the actual charging powers corresponding to the plurality of charging ports belonging to the second group to obtain a fourth sequence; The controller arranges the plurality of second sub-optimized powers based on the correspondence between the fourth sequence and the actual charging power and the plurality of second sub-optimized powers to obtain a fifth sequence; The fourth sequence is combined with the first unordered sequence, so that the actual charging power corresponding to the charging ports of the second group is regulated according to the corresponding second sub-optimal power.

[0061] It can be understood that, through the above steps, the powers of the charging ports belonging to the second group can be adjusted proportionally so that the second total power reduction value is the same as the second optimized power value.

[0062] The present application proposes an orderly charging control method, in which the controller divides multiple charging ports into a first group and a second group based on multiple actual charging powers, wherein 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, wherein the greater the actual charging power, the less power is reduced during the corresponding adjustment; the controller adjusts the charging power of the charging ports belonging to the second group, wherein the smaller the actual charging power, the less power is reduced during the corresponding adjustment. The present application proposes an orderly charging control method, in which when the total power of the entire charging system is reduced and regulated, when regulating the charging ports with higher charging time requirements, the value of reducing the charging power of the ports with higher charging time requirements is lower, and the impact on the charging time is lower. When regulating the charging ports with lower charging time requirements, the value of reducing the charging power of the charging ports with lower charging time requirements is lower, so as to minimize the problem that the power after regulation is lower than the minimum charging requirement of the vehicle.

[0063] Based on the same inventive concept, an embodiment of the present application proposes a charging pile, which includes multiple charging ports and a controller. The charging pile is configured as follows: 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; If the controller determines to perform power optimization, the controller obtains multiple corresponding actual charging powers of the multiple charging ports; The controller divides the plurality of charging ports into a first group and a second group based on the plurality of actual charging powers, wherein an average value of the actual charging powers corresponding to the charging ports belonging to the first group is greater than an average value of the actual charging powers corresponding to the charging ports belonging to the second group; The controller adjusts the charging power of the charging ports belonging to the first group, wherein the greater the actual charging power is, 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, wherein the smaller the actual charging power is, the smaller the power reduction during the corresponding adjustment is.

[0064] In some feasible implementations, 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: The controller obtains the current total power of multiple charging ports, compares the current total power with a preset value, and if the current total power is greater than the preset value, determines to optimize the power of the charging pile and obtains the optimized power, wherein the optimized power is the difference between the current total power of multiple charging ports and the target value.

[0065] In some feasible implementations, the controller adjusts the charging power of the charging ports belonging to the first group, wherein the greater the actual charging power is, the less the power is reduced during the corresponding adjustment, including: The controller obtains a first total power of charging ports belonging to a first group and a second total power of charging ports belonging to a second group; The controller divides the optimized power into a first optimized power and a second optimized power based on a ratio relationship between the first total power and the second total power; The controller optimizes the first total power based on the first optimized power so that a reduction value of the first total power is the same as a value of the first optimized power.

[0066] The controller adjusts the charging power of the charging ports belonging to the second group, wherein the smaller the actual charging power is, the smaller the power reduction is during the corresponding adjustment, including: The controller optimizes the second total power based on the second optimized power so that a reduction value of the second total power is the same as a value of the second optimized power.

[0067] In conjunction with the second aspect, in some feasible implementations, the controller divides the optimized power into a first optimized power and a second optimized power based on a ratio relationship between the first total power and the second total power, satisfying:

[0068] in, is the first total power, is the second total power, To optimize power first, Optimize power for the second.
