Description

Technical Field

[0001] The present application relates to the technical field of power battery charging, and in particular to a power sharing charging control method, system and device for multi-power cabinet charging piles. Background Art

[0002] A stack charging pile can match one power cabinet with multiple charging guns, or connect the DC outputs of multiple power cabinets to the same DC bus to meet higher-power charging needs. The number of charging guns and the total power configuration of the power cabinet are more flexible. Each power cabinet in the stack charging pile uses a separate power control unit. When multiple power cabinets are used to achieve power increase, how to cooperate between the control units of multiple power cabinets to achieve reasonable power sharing and distribution is a difficult problem that needs to be solved for high-power stack charging piles. In the related technology, the power allocation algorithm for multiple power cabinets usually simply divides the two power cabinets into a lending power cabinet and a borrowing power cabinet. The lending power cabinet provides shared power, and the borrowing power cabinet borrows shared power. This method generally only supports two power cabinets. The lending power cabinet allocates power for the original demand and shared demand according to the demand size. There are the following technical problems:

[0003] It is easy for the borrowed power cabinet to seize the original charging gun power in the lent power cabinet. In order to ensure the normal charging of the borrowed power cabinet, usually part of the power in the lent power cabinet is dedicated to power sharing, and the other part is dedicated to its own charging needs. However, if the required power of the charging gun of the borrowed power cabinet is too large, its charging needs cannot be met well. If there is no charging gun charging in the lent power cabinet, its own dedicated power cannot be lent, resulting in power waste and inability to participate in power sharing, affecting the overall charging efficiency. Summary of the invention

[0004] Based on this, it is necessary to provide a power sharing charging control method, system and equipment for a multi-power cabinet charging pile to address the above-mentioned technical problems, which can allocate all the shareable power of the lent power cabinet to the borrowed power cabinet for use, so that the power can be utilized to a greater extent, avoiding power waste, effectively improving the maximum output power of a single gun of the entire pile, and improving the charging efficiency of the vehicle.

[0016] In some examples, obtaining the borrowing priority of each of the borrowed power cabinets according to the required power of each of the borrowed power cabinets includes:

[0017] Sorting the required power of each borrowed power cabinet;

[0018] According to the sorting result of the required power, the borrowing priority of each of the borrowed power cabinets is determined, wherein the greater the required power is, the higher the borrowing priority is.

[0019] In some examples, allocating the sharable power of each borrowed power cabinet to the corresponding borrowed power cabinet according to the required power of each borrowed power cabinet includes:

[0020] According to the required power of each borrowed power cabinet, obtaining the borrowing ratio of each borrowed power cabinet;

[0021] According to the borrowing ratio of each borrowed power cabinet, the sharable power of each borrowed power cabinet is allocated to the corresponding borrowed power cabinet.

[0022] In some examples, the greater the required power, the higher the borrowing ratio.

[0023] In some examples, the sharable power of each of the lent power cabinets changes with changes in its own required power, and the priority of the lent power cabinet's own power demand is greater than the power demand shared with the borrowed power cabinet.

[0024] In a second aspect, a power sharing charging control system for a multi-power cabinet charging pile is provided, including:

[0025] An acquisition module is used to obtain the sharable power and required power of multiple power cabinets, wherein the sharable power of a power cabinet without required power is its own maximum output power;

[0036] The present application is further described in detail below in conjunction with the embodiments and drawings. It is to be understood that the specific embodiments described herein are only used to explain the relevant application, rather than to limit the application. It is also necessary to explain that, for ease of description, only the parts related to the application are shown in the drawings.

[0037] It should be noted that, in the absence of conflict, the embodiments of the present application, that is, the features of the embodiments, can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0038] The following describes in detail the power sharing charging control method, system and device of the multi-power cabinet charging pile according to the embodiments of the present application in conjunction with the accompanying drawings.

[0039] In the implementation environment of the embodiment of the present application, a computing device such as a computer or a terminal can be used to obtain the sharable power and required power of multiple power cabinets, wherein the sharable power of a power cabinet without required power is its own maximum output power; roles of the multiple power cabinets are determined based on the sharable power and required power of the multiple power cabinets, wherein the roles include lent power cabinets and borrowed power cabinets; and the sharable power of each lent power cabinet is allocated to the corresponding borrowed power cabinet based on the required power of each borrowed power cabinet, wherein the priority of the lent power cabinet's own power demand is greater than the power demand shared with the borrowed power cabinet.

[0040] Figure 1 It is a flow chart of a power sharing charging control method for a multi-power cabinet charging pile according to an embodiment of the present application.

[0041] like Figure 1As shown, according to an embodiment of the present application, a power sharing charging control method for a multi-power cabinet charging pile includes the following steps:

[0042] S101: obtaining sharable power and required power of multiple power cabinets, wherein the sharable power of a power cabinet without required power is its own maximum output power.

[0043] Specifically, a multi-power cabinet charging pile includes multiple power cabinets. Generally speaking, each power cabinet is equipped with a power control unit, which can communicate with the power control unit of each power cabinet, and then obtain the shareable power and required power of each power cabinet from the power control unit of each power cabinet.

[0044] like Figure 2 As shown, in a specific application, a power sharing control unit can communicate with the power control unit of each power cabinet, so that the power sharing control unit can obtain the shareable power and required power of each power cabinet from the power control unit of each power cabinet. Figure 2 The circular mark in the figure indicates the sender of the message, and the triangle mark and the direction pointed by the arrow indicate the receiver of the message. The power sharing control unit controls the overall steps of power sharing, is responsible for dividing the borrowing and lending roles of each power cabinet, and the power control unit in each power cabinet controls the charging module in the power cabinet to output and control the corresponding contactor.

[0045] Combination Figure 2 As shown, four power cabinets are shown, namely: power cabinet 1, power cabinet 2, power cabinet 3 and power cabinet 4. Correspondingly, power cabinet 1 is equipped with power cabinet 1 power control unit, power cabinet 2 is equipped with power cabinet 2 power control unit, power cabinet 3 is equipped with power cabinet 3 power control unit, and power cabinet 4 is equipped with power cabinet 4 power control unit. In this way, the power sharing control unit can obtain the shareable power and required power of power cabinet 1 from the power control unit of power cabinet 1, the shareable power and required power of power cabinet 2 from the power control unit of power cabinet 2, the shareable power and required power of power cabinet 3 from the power control unit of power cabinet 3, and the shareable power and required power of power cabinet 4 from the power control unit of power cabinet 4.

[0046] The stage in which the power sharing control unit obtains the sharable power and required power of multiple power cabinets can be called the idle stage, that is, when the working stage of the power sharing control unit is marked as the idle stage, each power control unit sends the available power (that is, sharable power) and required power to the power sharing control unit according to its own supply and demand situation.

[0047] like Figure 2As shown, the power sharing control unit marks the power sharing working stage as the idle stage. At this time, the power control unit of power cabinet 1, the power control unit of power cabinet 2, the power control unit of power cabinet 3 and the power control unit of power cabinet 4 respectively send the shareable power and required power of power cabinet 1, power cabinet 2, power cabinet 3 and power cabinet 4 to the power sharing control unit.

[0048] In the above description, the shareable power refers to the surplus power that can be provided, and the required power refers to the power requested by the vehicle when the vehicle needs to be charged.

[0049] S102: Determine roles of the multiple power cabinets according to the sharable power and required power of the multiple power cabinets, where the roles include a lending power cabinet and a borrowing power cabinet.

[0050] In one embodiment of the present application, the roles of multiple power cabinets are determined based on the sharable power and required power of the multiple power cabinets, including: if the first power cabinet currently has sharable power, then the first power cabinet is determined to be a loaned power cabinet; if the first power cabinet currently does not have the sharable power, then the first power cabinet is determined to be a borrowed power cabinet, wherein the first power cabinet is any one of the multiple power cabinets.

[0051] like Figure 2 As shown, assuming that the power control unit of power cabinet 1, the power control unit of power cabinet 3 and the power control unit of power cabinet 4 send sharable power to the power sharing control unit, the roles of power cabinet 1, power cabinet 3 and power cabinet 4 are determined to be lending power cabinets, and the power control unit of power cabinet 2 sends required power to the power sharing control unit, then the role of power cabinet 2 is determined to be borrowing power cabinet.

[0052] In this example, the required power can be determined by the required voltage and the required current.

[0053] S103: Allocate the sharable power of each borrowed power cabinet to the corresponding borrowed power cabinet according to the required power of each borrowed power cabinet, wherein the sharing priority of the sharable power of each borrowed power cabinet is greater than the borrowing priority of each borrowed power cabinet.

[0054] In one embodiment of the present application, the sharable power of each lent power cabinet is allocated to the corresponding borrowed power cabinet according to the required power of each borrowed power cabinet, including: obtaining the borrowing priority of each borrowed power cabinet according to the required power of each borrowed power cabinet; and according to the borrowing priority of each borrowed power cabinet, preferentially allocating the sharable power of each lent power cabinet to the borrowed power cabinet with a high borrowing priority.

[0055] In this example, the borrowing priority of each borrowed power cabinet is obtained according to the required power of each borrowed power cabinet, including: sorting the required power of each borrowed power cabinet; determining the borrowing priority of each borrowed power cabinet according to the sorting result of the required power, wherein the greater the required power, the higher the borrowing priority.

[0056] like Figure 2 As shown, in the specific process, after the borrowing and lending roles are determined, for example, it is determined that the roles of power cabinet 1, power cabinet 3 and power cabinet 4 are the lending power cabinets, and the role of power cabinet 2 is the borrowing power cabinet. After the determination is completed, the power sharing control unit marks the working stage as the connection stage, and the borrowing power cabinet control unit (i.e., the power control unit of power cabinet 1, the power control unit of power cabinet 3 and the power control unit of power cabinet 4) and the lending power control unit (i.e., the power control unit of power cabinet 2) close the corresponding contactors and feedback the closing status of the contactors.

[0057] When all power control units close the contactors, the power sharing control unit marks the power sharing working stage as the output stage, and the incoming power cabinet control unit sends the required voltage, required current, etc. to the outgoing power control unit, and sends the current shareable power.

[0058] It should be noted that the loaned part of the lent power cabinet has the lowest priority and will not preempt the power of the original charging gun, that is: the sharable power of each lent power cabinet changes with the change of its own required power, and the occupation priority of the required power of each lent power cabinet is greater than the sharing priority of its sharable power. Therefore, when the lent power cabinet has no required power, all the power can be lent to the borrowed power cabinet as sharable power, thereby avoiding power waste, greatly improving the charging power of the borrowed power cabinet, and avoiding the maximum output power of a single gun being limited. When the lent power cabinet has a demand for power, since the occupation priority of the required power of the lent power cabinet is greater than the sharing priority of its sharable power, the lent power cabinet can share the remaining power with the connected power cabinet while meeting its own power demand, so that the power is maximized.

[0059] In the above example, the shareable power allocated by the lending power cabinet to the borrowing power cabinet is determined based on the power demand of the borrowing power cabinet, that is, the borrowing power cabinet with the largest power demand is given priority. Figure 2As shown, assuming that the shareable power of power cabinet 2 is 40 kWh, the required power of power cabinet 1 is 60 kWh, the required power of power cabinet 3 is 80 kWh, and the required power of power cabinet 4 is 30 kWh, then the required power of power cabinet 3 is the highest, and the shareable power of power cabinet 2 is preferentially allocated to power cabinet 3. If there is any surplus, it is allocated to power cabinet 1, and if there is any surplus, it is finally allocated to power cabinet 4. In this way, the power cabinets with high demand power can be met first. Generally speaking, the higher the demand power, the more urgent the charging demand. Therefore, the power can be preferentially allocated to the power cabinets that need it most, so as to better meet the charging demand.

[0060] In the above example, the sharable power lent by the lent power cabinet is determined according to the required power of the borrowed power cabinet. In another example, it can also be allocated in other ways, for example: according to the required power of each of the borrowed power cabinets, the sharable power of each of the lent power cabinets is allocated to the corresponding borrowed power cabinet, including: according to the required power of each of the borrowed power cabinets, obtaining the borrowing ratio of each of the borrowed power cabinets; according to the borrowing ratio of each of the borrowed power cabinets, allocating the sharable power of each of the lent power cabinets to the corresponding borrowed power cabinets.

[0061] In this example, the greater the required power is, the higher the borrowing ratio is.

[0062] Combination Figure 2 As shown, assuming that the shareable power of power cabinet 2 is 40 kWh, the required power of power cabinet 1 is 50 kWh, the required power of power cabinet 3 is 30 kWh, and the required power of power cabinet 4 is 20 kWh, then the ratio of the required power of power cabinet 1, power cabinet 3 and power cabinet 4 is 5:3:2. At this time, the 40 kWh of shareable power in power cabinet 2 can be correspondingly allocated to power cabinet 1, power cabinet 3 and power cabinet 4 in a ratio of 5:3:2, for example: 20 kWh to power cabinet 1, 12 kWh to power cabinet 3, and 8 kWh to power cabinet 4. In this way, power distribution can be achieved more evenly. This enables each borrowed power cabinet to achieve an improvement in charging capacity.

[0063] like Figure 2 As shown in the figure, when all power control units close the contactors, the power sharing control unit marks the power sharing working stage as the output stage, the borrowing role sends the required voltage, required current, etc., and the lending power control unit sends the current available power. The power sharing control unit continues to clarify the borrowing and lending roles and the borrowing role priorities, and the lending power control unit allocates its own available power according to the borrowing role priorities. The lending part of the lending power cabinet has the lowest priority and will not preempt the power of the original charging gun.

[0064] When the power of the borrowed power cabinet is insufficient, the available power will be sent to the power sharing control unit as 0, and the power sharing control unit will mark the power sharing working stage as the end stage. When the required power of the borrowed power cabinet is 0, the required power will also be sent to the power sharing control unit as 0, and the power sharing working stage will also enter the end stage.

[0065] The power sharing control unit will release the borrowing and lending roles of each power control unit at the end stage. After receiving the instruction, the lending power control unit will shut down the charging module and disconnect the contactor. The borrowing power control unit will also disconnect the contactor and feedback the contactor status. When all contactors are disconnected, the power sharing working stage re-enters the idle stage.

[0066] like Figure 2 As shown, in the output stage, for example: the power control unit of power cabinet 2, that is, the power cabinet is lent, sends a message to the power sharing control unit that the available power of the lent power cabinet (that is, the shareable power) is 0, and then enters the end stage. For another example: the power control unit of power cabinet 1, that is, the power cabinet is borrowed, sends a message to the power sharing control unit that the required power is 0, and also enters the end stage.

[0067] According to the power sharing charging control method of the multi-power cabinet charging pile of the embodiment of the present application, the role of the power cabinet can be determined according to the shareable power and required power of multiple power cabinets, and then the shareable power of each lent power cabinet can be allocated to the borrowed power cabinet according to the required power of each borrowed power cabinet. Since the shareable power of the power cabinet that has no charging power demand is its own maximum output power, all the power of the lent power cabinet (i.e., the current shareable power) can be allocated to the borrowed power cabinet for use, so that the power is utilized to a greater extent, avoiding power waste, effectively improving the maximum output power of a single gun of the entire pile, and improving the charging efficiency of the vehicle.

[0068] Figure 3 1 is a block diagram of a power sharing charging control system for a multi-power cabinet charging pile according to an embodiment of the present application. Figure 3 As shown, according to an embodiment of the present application, a power sharing charging control system for a multi-power cabinet charging pile includes: an acquisition module 310, a role allocation module 320 and a power allocation module 330, wherein:

[0069] An acquisition module 310 is used to obtain the sharable power and required power of multiple power cabinets, wherein the sharable power of a power cabinet without required power is its own maximum output power;

[0070] A role allocation module 320, configured to determine roles of the plurality of power cabinets according to the sharable power and required power of the plurality of power cabinets, wherein the roles include a lending power cabinet and a borrowing power cabinet;

[0071] The power allocation module 330 is used to allocate the sharable power of each lent power cabinet to the corresponding borrowed power cabinet according to the required power of each borrowed power cabinet, wherein the priority of the power demand of the lent power cabinet itself is greater than the power demand shared with the borrowed power cabinet.

[0072] According to the power sharing charging control system of the multi-power cabinet charging pile of the embodiment of the present application, the role of the power cabinet can be determined according to the shareable power and required power of multiple power cabinets, and then the shareable power of each lent power cabinet can be allocated to the borrowed power cabinet according to the required power of each borrowed power cabinet. Since the shareable power of the power cabinet that has no charging power demand is its maximum output power, all the power of the lent power cabinet (i.e., the current shareable power) can be allocated to the borrowed power cabinet for use, so that the power is utilized to a greater extent, avoiding power waste, effectively improving the maximum output power of a single gun of the entire pile, and improving the charging efficiency of the vehicle.
