[0225] The preferred embodiments of the present application are described below with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely used to explain the technical principles of the present application and are not intended to limit the scope of protection of the present application. For example, although the present embodiment is described in conjunction with a pure electric vehicle, this is not intended to limit the scope of protection of the present application. Without departing from the principles of the present application, those skilled in the art may apply the present application to other application scenarios. For example, the present application is also applicable to new energy vehicles such as hybrid vehicles that require charging.

[0226] It should be noted that, in the description of this application, the terms "first" and "second" are used for descriptive purposes only and should not be understood as indicating or implying relative importance.

[0227] It should also be noted that, in the description of this application, unless otherwise expressly specified or limited, the terms "installed," "connected," and "connected" should be understood in a broad sense. For example, they can refer to fixed connections, detachable connections, or integral connections; mechanical connections or electrical connections; direct connections or indirect connections through an intermediate medium; and internal connections between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on the specific circumstances.

[0228] First refer to Figure 1 , briefly introduce the charging and swapping station of this application. Among them, Figure 1 This is a system diagram of the charging and swapping station of the present application, in which the solid line represents the circuit and the dotted line represents the communication line.

[0229] like Figure 1 As shown, the charging and swapping station of the present application includes a battery swapping station 1 and a charging pile 2. The battery swapping station 1 includes a first control unit 11 and one or more battery compartments (not shown in the figure). Each battery compartment includes a charging branch 12. When the power battery is in the battery compartment, the charging branch 12 engages with the power battery and charges the power battery. The first control unit 11 is arranged in the battery swapping station 1, and each battery compartment is communicatively connected to the first control unit 11 so that the first control unit 11 sends a power distribution instruction to the battery compartment to control the charging power of the battery compartment. The charging pile 2 includes a charging gun (not shown in the figure) and a second control unit 21. The charging gun can be plugged into and connected to the charging seat provided on the new energy vehicle. The charging gun is electrically connected to the second control unit 21, and the second control unit 21 is communicatively connected to the first control unit 11, so that the second control unit 21 can receive the power distribution instruction sent by the first control unit 11 and control the charging gun to charge the new energy vehicle based on the power distribution instruction.

[0230] The power of the charging and swapping station 1 is introduced by a busbar 5, and all the battery compartments and charging piles 2 are connected to the busbar 5. The battery swapping station 1 is provided with a first control unit 11, electrical equipment in the station and one or more battery compartments. The first control unit 11 preferably adopts the master control system (Master Control Switch, MCS for short) of the battery swapping station 1, which is arranged in the control cabinet of the battery swapping station 1. It is mainly used to coordinate the actions of all equipment in the battery swapping station 1 according to the preset control logic, such as coordinating the charging power and charging start and stop timing when charging the batteries in the battery compartment, coordinating the actions of each battery swapping mechanism when replacing the power battery for the electric vehicle to be swapped, interacting with the cloud server, and controlling the auxiliary equipment in the charging and swapping station 1 such as lighting devices and cooling devices.

[0231] Generally, the performance of the main control system of the battery swap station 1 is much stronger than the second control unit 21 of the charging pile 2. By using the main control system of the battery swap station 1 as the first control unit 11 to complete the power distribution between the battery compartment and the charging pile 2, a fast and stable distribution strategy response can be achieved to ensure the stable operation of the charging and swap station 1.

[0232] It should be noted that although the specific model of the main control system is not described in this application, this does not mean that the main control system is not fully disclosed. On the contrary, the main control system is a necessary control device for the battery swap station 1. Those skilled in the art are aware of its specific selection and configuration, so it will not be described in detail in this application.

[0233] The electrical equipment in the station mainly refers to other electrical equipment except the battery compartment, including but not limited to battery replacement process equipment (such as battery replacement carts, battery transfer equipment, lifting mechanisms, locking and unlocking mechanisms, positioning mechanisms, etc.), lighting equipment, communication equipment, etc. The power of these devices is generally fixed when working and needs to be fixedly provided by the bus 5. In this embodiment, 13 battery compartments are set as an example, where the 13 battery compartments are divided into two groups. The first 6 battery compartments together with other electrical equipment in the station are the first group, which are connected to the bus 5 through the same circuit breaker, and the last 7 battery compartments are the second group, which are connected to the bus 5 through another circuit breaker. Each battery compartment includes a charging branch 12, and each charging branch 12 includes a charging control board, a charging AC / DC module, a DC contactor, etc. The charging control board is communicatively connected to the first control unit 11. Preferably, each charging control board is communicatively connected to the first control unit 11 via a CAN bus.

[0234] In this application, charging pile 2 is a DC charging pile, more specifically, a super charging pile. It features high charging power and current, enabling fast, intelligent, and reliable charging for new energy vehicles. In this embodiment, six super charging piles are provided, grouped together and connected to busbar 5 via a circuit breaker. Each super charging pile is equipped with a second control unit 21, which is in communication with the first control unit 11.

[0235] Continue to see Figure 1 The battery swap station 1 is also equipped with a data exchange device 13. The first control unit 11 and the second control unit 21 are simultaneously connected to the data exchange device 13, thereby establishing a communication connection between the first control unit 11 and the second control unit 21. Specifically, the data exchange device 13 is a switch, and the first control unit 11 and / or the second control unit 21 are connected to the data exchange device 13 via a wired communication connection. In this application, the first control unit 11 and the second control unit 21 are connected to the switch via an RJ45 communication cable. When the battery swap station 1 is in operation, the first control unit 11 of the battery swap station 1 communicates with the second control unit 21 of the charging pile 2 via the switch. The communication cycle can be manually set, such as 2s-30s. In this application, 5s is used as an example. That is, every 5 seconds, the second control unit 21 of the charging pile 2 will send the charging power request of the charging pile 2 to the switch. The switch transmits the charging power request to the first control unit 11. After the first control unit 11 determines the power allocation, it transmits the power allocation instruction back to the second control unit 21 via the switch. The second control unit 21 then controls the charging output power of the charging pile 2 based on the instruction.

[0236] The first control unit 11 and the second control unit 21 are connected to the switch in a wired manner to ensure signal transmission stability. By using a switch to achieve communication connection between the first control unit 11 and the second control unit 21, connection efficiency can be improved and data transmission security can be guaranteed.

[0237] The charging and swapping station 1 also includes a measurement and control meter 3, which is in communication with the first control unit 11 and is used to measure the power of the entire charging and swapping station 1. Specifically, the measurement and control meter 3 is set on the bus 5, so that the power of the entire charging and swapping station 1 can be measured directly from the bus 5. In this way, the first control unit 11 can directly obtain the power of the entire charging and swapping station 1 and allocate the power of each charging device based on the power of the entire station, realizing real-time load power monitoring of the entire station, avoiding tripping and device damage caused by excessive power operation of the station from the source of power supply, and reducing operation and maintenance costs.

[0238] When the charging and swapping station 1 is put into use, the first control unit 11 obtains the charging request power of each rechargeable battery in the battery compartment and the charging request power of each charging pile 2 respectively, and then determines the power allocated to each battery compartment and each charging pile 2 based on the current maximum available power of the station, the charging request power of each battery compartment, and the charging request power of each charging pile 2. Then, based on the allocation result, control instructions are issued to each battery compartment and charging pile 2 so that each battery compartment and each charging pile 2 can work according to the power allocated to them.

[0239] It should be noted that although the above embodiment describes a specific configuration of the charging and swapping station 1, this is not intended to limit the scope of protection of this application. Without departing from the principles of this application, those skilled in the art may adjust the specific form of the above charging and swapping station 1 so that the power control method described below in this application can be applied to more application scenarios.

[0240] For example, although the above embodiment is introduced in conjunction with the data exchange device 13 as a switch, this setting method is not fixed and can be adjusted by those skilled in the art as long as the adjusted technical solution can meet the communication connection between the first control unit 11 and the second control unit 21. For example, in other embodiments, a hub can be used to achieve the communication connection between the two, or the switch setting can be omitted so that the two are directly connected through a data line. In addition, the connection method between the first control unit 11, the second control unit 21 and the switch can be wired, such as a wired network (RJ45), RS485 / 232, power line carrier (PLC), etc., or wireless, such as WIFI, Bluetooth, ZIGBEE, etc., and of course, it can also be a form of cross-wiring of wired and wireless.

[0241] For example, in another alternative embodiment, although the above embodiment is described in conjunction with the first control unit 11 and the battery compartment being connected via a CAN bus, this communication connection method is not fixed and can be adjusted by those skilled in the art based on specific application scenarios. For example, the CAN bus can also be replaced by a 485 bus.

[0242] For example, in another replaceable embodiment, the specific composition of the charging branch 12 of the battery compartment is described in the above embodiment in combination with a charging control board, a charging AC / DC module and a DC contactor, but this is not intended to limit the scope of protection of this application. Those skilled in the art can replace the above-mentioned charging branch 12 with any form of charging branch.

[0243] For example, in another alternative embodiment, although a measurement and control meter 3 is provided in the above-mentioned charging and swapping station 1, the measurement and control meter 3 is not necessary in this application, and those skilled in the art can decide whether to use it or not based on the specific application scenario.

[0244] For example, in another alternative embodiment, although the above-mentioned first control unit 11 preferably adopts the main control system of the battery swap station 1, it is obvious that this setting method is not the only one. In other embodiments, those skilled in the art can set up a separate controller to complete the function of the above-mentioned first control unit 11.

[0245] For example, in another replaceable embodiment, although the above-mentioned charging pile 2 is introduced as a super charging pile, the charging and swapping station 1 of the present application is not limited to this. In other embodiments, the super charging pile can also be replaced with an ordinary DC charging pile, or further replaced with an AC charging pile.

[0246] Of course, the above-mentioned replaceable implementations, as well as the replaceable implementations and the preferred implementations, can be used in a cross-functional manner to combine new implementations to suit more specific application scenarios.

[0247] Refer to the following Figure 2 , the power control method of the charging and swapping station of this application is introduced. Among them, Figure 2 This is a flow chart of the power control method of the charging and swapping station of the present application.

[0248] like Figure 2 As shown, in order to achieve comprehensive power management of the charging and swapping station, the power control method of the present application mainly includes the following steps:

[0249] S101. Obtain the power limit of the charging and swapping station, the total requested power at the station end of the swapping station, and the total requested power at the pile end of several charging piles. For example, the power limit can be a fixed value set manually, or it can be calculated or obtained in real time based on the information of the upstream power grid. The specific acquisition method is not limited in this application, as long as the power limit can be accurately obtained. The total requested power at the station end of the swapping station includes the charging request power (or warehouse end request power) of all battery compartments that need to be charged and the power consumption of the electrical equipment in the station (or non-charging power consumption). The sum of the two powers is the total requested power at the station end. The total requested power at the pile end of the charging pile includes the requested power (or pile end request power) of all charging piles that need external services. The first control unit obtains the warehouse end request power and non-charging power consumption of each battery compartment by communicating with the battery compartment and the electrical equipment in the station, and adds the two together to calculate the total requested power at the station end. The first control unit obtains the pile end request power of each charging pile by communicating with the second control unit and sums them up to obtain the total requested power at the pile end.

[0250] S103: Calculate the sum of the total requested power of the station and the total requested power of the charging / swapping station. For example, after obtaining the total requested power of the station and the total requested power of the charging / swapping station, the first control unit calculates the sum of the two powers, that is, the total requested power of the charging / swapping station.

[0251] S105. Compare the power limit value and the total power; for example, compare the power limit value and the total requested power of the charging and swapping station by calculating the difference or ratio between the two.

[0252] S107. When the power limit is less than the sum of the powers, the actual power allocated to the station end of the battery swap station and the actual power allocated to the pile end of several charging piles are determined based on the preset allocation strategy. For example, when the power limit is greater than or equal to the sum of the powers, it is proved that the current power limit can meet the power requests of each battery compartment and each charging pile. At this time, power allocation can be performed according to the compartment end request power and the pile end request power. When the power limit is less than the sum of the powers, it is proved that the power limit cannot meet the power request of at least one of the battery compartment and the charging pile, and further power allocation is required to avoid power over-limit operation. At this time, the actual power allocated to the station end of the battery swap station and the actual power allocated to the pile end of several charging piles are determined based on the preset allocation strategy. The preset allocation strategy can, for example, be to give priority to the power allocation of all charging piles, or to give priority to the power allocation of all battery compartments, or to allocate power to the battery compartments and charging piles according to a preset allocation ratio. The following embodiment will expand on a more preferred allocation method.

[0253] S109: Based on the actual allocated power at the station end and the actual allocated power at the charging pile end, power is allocated to one or more battery compartments and several charging piles. For example, after determining the actual allocated power at the outbound end and the actual allocated power at the charging pile end, power is allocated to the battery compartments that need to be charged based on the actual allocated power at the station end, and power is allocated to the charging piles that need to provide services based on the actual allocated power at the charging pile end.

[0254] From the above description, it can be seen that when the power limit is less than the sum of the total requested power of the station end and the total requested power of the pile end, the actual allocated power of the station end and the actual allocated power of the pile end are determined based on the preset allocation strategy, and then the power is allocated to the battery compartment and the charging pile based on the actual allocated power of the station end and the actual allocated power of the pile end. This application solves the comprehensive power management problem of integrated battery swap stations and charging piles, realizes flexible and efficient power allocation under limited power, and ensures service capabilities.

[0255] The following describes the preferred embodiments of the present application.

[0256] In one possible implementation, the total requested power at the battery swap station is determined based on the following method: obtaining the required number N of batteries; selecting N batteries with the highest remaining power from the battery swap station; calculating the total requested charging power of the N batteries; calculating the non-charging power of the electrical equipment within the battery swap station; and calculating the sum of the total requested charging power and the non-charging power as the total requested power at the station; wherein the required number of batteries is determined based on the battery swap reservation order at the battery swap station.

[0257] For example, a battery swap station is connected to a cloud server, such as through a first control unit. Electric vehicle users can make reservations for battery swap services at a battery swap station through a smart terminal (such as a car computer, mobile phone, computer, tablet computer, etc.). The cloud server counts the number of battery swap reservations for each battery swap station, that is, the number of battery requirements (assuming N), and then sends the battery requirement number N at that moment to the battery swap station. Based on this number N, the battery swap station selects the N batteries (including fully charged batteries) with the highest remaining charge (SOC) and sets the operating mode of these N batteries to charging mode, that is, first starting the battery at a low power and then charging according to the battery's required power (fully charged batteries do not need to be started and charged). Those skilled in the art know that when a battery is in different power ranges, its required power is different. Generally speaking, the more remaining power in the battery, the lower its required power. Next, the terminal requested power of each battery compartment is calculated and summed to obtain the total charging power request of the N batteries. Then, based on the power requirements of the station's electrical equipment, the non-charging power is calculated. Finally, the sum of the total charging power request and the non-charging power request is calculated as the total station-side requested power.

[0258] By determining the battery demand quantity N based on the battery swap reservation orders at the battery swap station, and then determining the total requested power at the station, this application can coordinate as much power as possible to be allocated to the charging piles while ensuring that the service capacity of the battery swap station is not affected, thereby effectively improving the utilization rate of the station's capacity.

[0259] Of course, in other implementations, the total requested power at the station end can also be calculated based on the requested power at the station end of all battery compartments that need to be charged in the current battery swap station, but this distribution method will inevitably reduce the utilization rate of the station's electrical capacity.

[0260] In one possible implementation, the above step S107 further includes: determining the station-side pre-allocated power of the battery swap station and the pile-side pre-allocated power of several charging piles; comparing the station-side pre-allocated power with the station-side total requested power, and the pile-side pre-allocated power with the pile-side total requested power; based on the comparison result, determining the station-side actual allocated power and the pile-side actual allocated power. Specifically, if the station-side pre-allocated power is greater than or equal to the station-side total requested power, then the station-side actual allocated power is determined to be the station-side total requested power, and the pile-side actual allocated power is determined to be the difference between the power limit and the station-side total requested power; if the pile-side pre-allocated power is greater than or equal to the pile-side total requested power, then the pile-side actual allocated power is determined to be the pile-side total requested power, and the station-side actual allocated power is determined to be the difference between the power limit and the pile-side total requested power; if the station-side pre-allocated power is less than the station-side total requested power, and the pile-side pre-allocated power is less than the pile-side total requested power, then the station-side actual allocated power is determined to be the station-side pre-allocated power, and the pile-side actual allocated power is determined to be the pile-side pre-allocated power.

[0261] For example, in a preferred embodiment, the station-side pre-allocated power and the pile-side pre-allocated power may be determined using the following formula:

[0262] Pscmd=N×a+Pswap (1)

[0263] Pccmd=PL-Pscmd (2)

[0264] In formulas (1) and (2), Pscmd is the pre-allocated power at the station end; N is the number of batteries required; a is the power constant, which can be comprehensively considered in combination with the actual operating conditions and the charging branch power limit of the battery compartment; Pswap is the non-charging power consumption of the electrical equipment in the battery swap station; Pccmd is the pre-allocated power at the pile end; and PL is the power limit.

[0265] That is to say, when the power limit is insufficient to enable the battery compartment and the charging pile to operate at their respective total requested powers, the station-side pre-allocated power and the pile-side pre-allocated power are first determined based on formulas (1) and (2), and then based on the station-side pre-allocated power and the pile-side pre-allocated power, it is determined whether one of the two can meet the station-side total requested power or the pile-side total requested power. If they can be met, the total requested power that can be met is used as the actual allocated power of the end.

[0266] For example, taking PL = 500kW, N = 5, a = 30kW, Pswap = 20kW, the total requested power at the station end Psr1 = 150kW, and the total requested power at the pile end Pcr1 = 400kW as an example, the above formulas (1) and (2) can be used to calculate the station-side pre-allocated power Pscmd = N × a + Pswap = 5 × 30 + 20 = 170kW and the pile-side pre-allocated power Pccmd = PL - Pscmd = 500 - 170 = 330kW. It can be seen that Pscmd > Psr1. At this time, the station-side pre-allocated power can meet the total requested power at the station end of the battery compartment. Therefore, the actual allocated power at the station end P'scmd = Psr1 = 150kW and the actual allocated power at the pile end P'ccmd = PL - Psr1 = 350kW, giving priority to ensuring the allocation of the total requested power in the battery compartment.

[0267] For example, taking PL = 500kW, N = 5, a = 30kW, Pswap = 20kW, the total requested power at the station end Psr2 = 220kW, and the total requested power at the pile end Pcr2 = 300kW as an example, the station end pre-allocated power Pscmd = 170kW and the pile end pre-allocated power Pccmd = 330kW can be calculated respectively by the above formulas (1) and (2). It can be seen from this that Pscmd < Psr2, and Pccmd > Pcr2. At this time, the pile end pre-allocated power can meet the total requested power of the charging pile end. Therefore, the actual allocated power at the pile end P'ccmd = Pcr2 = 300kW, and the actual allocated power at the station end P'scmd = PL - Pcr2 = 200kW, giving priority to ensuring the allocation of the total requested power of the charging pile.

[0268] For another example, taking PL = 500kW, N = 5, a = 30kW, Pswap = 20kW, the total requested power of the station end Psr3 = 220kW, and the total requested power of the charging pile end Pcr3 = 350kW as an example, the station end pre-allocated power Pscmd = 170kW and the charging pile end pre-allocated power Pccmd = 330kW can be calculated respectively by the above formulas (1) and (2). It can be seen from this that Pscmd < Psr3, and Pccmd < Pcr3. At this time, the station end pre-allocated power and the charging pile end pre-allocated power cannot meet the total requested power of the station end and the charging pile end, so the actual allocated power of the charging pile end P'scmd = Pscmd = 170kW and the actual allocated power of the charging pile end P'ccmd = Pccmd = 330kW, ensuring the balanced distribution of the total requested power of the battery compartment and the charging pile.

[0269] By first determining the station-side pre-allocated power and the pile-side pre-allocated power, and then further determining the station-side actual allocated power and the pile-side actual allocated power based on the station-side pre-allocated power and the pile-side pre-allocated power, the control method of the present application first performs total power distribution between the battery swap station and the charging piles, and then performs power distribution between the battery compartments in the battery swap station and power distribution between the charging piles, while ensuring the total distribution efficiency between the battery swap station and the charging piles, and realizing balanced and efficient distribution of limited power.

[0270] In a possible implementation, after determining the actual allocated power at the outbound end and the actual allocated power at the base station end, step S109 is described in detail with respect to the above three allocation results.

[0271] i) When the actual allocated power at the station end is the total requested power at the station end and the actual allocated power at the charging pile end is the difference between the power limit and the total requested power at the station end, step S109 further includes: allocating power to each battery compartment according to its compartment end requested power; based on the actual allocated power at the charging pile end, evenly allocating power to each charging pile; determining whether the actual power at the charging pile end obtained by each charging pile is redundant; and if so, redistributing the redundant power of the charging pile with redundant actual power at the charging pile end to the charging pile with non-redundant actual power at the charging pile end.

[0272] For example, when the actual power allocated at the station end is the total requested power at the station end, each battery compartment that needs to be charged can obtain the power it requires. At this time, power is allocated to each battery compartment according to the compartment-end requested power of each battery compartment. When the actual power allocated at the pile end is the difference between the power limit and the total requested power at the station end, at least some charging piles cannot obtain the power they require. In this state, power is first allocated once according to the actual power allocated at the pile end, that is, power is evenly distributed to each charging pile. Then, after the allocation is completed, it is determined whether the actual power obtained by each charging pile at the pile end is redundant. For example, by judging the size of the pile end requested power and the average power obtained (pile end actual power), it is determined whether the charging pile has power redundancy. If there is redundancy, the redundant power is allocated twice to the charging piles whose actual power at the pile end is not redundant.

[0273] In one possible implementation, the redundant power of the station end may be allocated as follows:

[0274] Method 1: All redundant power is evenly distributed to other charging piles without power redundancy. If redundancy continues to occur after the distribution is completed, the above method is continued to be evenly distributed until no charging pile has power redundancy.

[0275] Method 2: Allocate power according to the priority of charging order. That is, allocate the redundant power first to the charging pile that starts providing charging service first among the remaining charging piles. If there is still redundant power, continue to allocate it according to the above priority until there is no redundant power at any charging pile.

[0276] ii) When the actual allocated power at the charging pile end is the total requested power at the charging pile end and the actual allocated power at the station end is the difference between the power limit and the total requested power at the charging pile end, step S109 further includes: allocating power to each charging pile according to its requested power at the charging pile end; based on the actual allocated power at the station end, evenly allocating power to each battery compartment; determining whether the actual power at the compartment end obtained by each battery compartment is redundant; and if there is redundancy, redistributing the redundant power of the battery compartment with redundant actual power at the compartment end to the battery compartment with non-redundant actual power at the compartment end.

[0277] For example, when the actual power allocated at the pile end is the total requested power at the pile end, each charging pile providing charging services can obtain the power it requires. At this time, power is allocated to each charging pile according to the pile end requested power of each charging pile. When the actual power allocated at the station end is the difference between the power limit and the total requested power at the pile end, at least some battery cells cannot obtain the power they require. In this state, power is first allocated once according to the actual power allocated at the station end, that is, power is evenly distributed to each battery cell. After the allocation, it is determined whether the actual power obtained by each battery cell at the cell end is redundant. For example, by determining the size of the requested power at the cell end and the average power obtained (actual power at the cell end), it is determined whether the battery cell has power redundancy. If there is redundancy, the redundant power is allocated twice to the battery cell whose actual power at the cell end is not redundant.

[0278] In one possible implementation, the redundant power at the warehouse end may be allocated as follows:

[0279] Method 1: All redundant power is evenly distributed to other battery compartments without power redundancy. If redundancy still occurs after the distribution is completed, continue to distribute evenly in the same way as above until no battery compartment has power redundancy.

[0280] Method 2: Allocate power based on the priority of remaining power. That is, redundant power is allocated first to the battery compartment with the highest remaining power among the remaining battery compartments. If there is still power redundancy, continue to allocate power based on the above priority until there is no power redundancy in the battery compartment.

[0281] Method 3: Allocate power based on battery capacity priority. This means allocating redundant power to the battery compartment with the largest battery capacity among the remaining battery compartments. If there is still power redundancy, continue allocating power based on the above priority until no battery compartment has power redundancy.

[0282] iii) When the actual allocated power at the station end is the pre-allocated power at the station end and the actual allocated power at the pile end is the pre-allocated power at the pile end, step S109 further includes: based on the actual allocated power at the station end, evenly distributing power to each battery compartment; judging whether the actual power at the compartment end obtained by each battery compartment is redundant; if there is redundancy, redistributing the redundant power of the battery compartment with redundant actual power at the compartment end to the battery compartment without redundant actual power at the compartment end; based on the actual allocated power at the pile end, evenly distributing power to each charging pile; judging whether the actual power at the pile end obtained by each charging pile is redundant; if there is redundancy, redistributing the redundant power of the charging pile with redundant actual power at the pile end to the charging pile without redundant actual power at the pile end.

[0283] For example, when the actual power allocated to the station is the pre-allocated power at the station and the actual power allocated to the charging pile is the pre-allocated power at the charging pile, there are devices in both the battery compartment and the charging pile that cannot obtain the power they require. In this state, the primary and secondary power allocations for the battery compartment are performed according to the actual power allocated to the station, and the primary and secondary power allocations for the charging pile are performed according to the actual power allocated to the charging pile. The primary and secondary allocations for the station and the charging pile are the same as those described above and will not be described in detail here.

[0284] By performing primary and secondary power distribution on the battery compartment / charging pile when the actual power allocated at the station / pile end is less than the total requested power at the station / pile end, as many devices as possible can operate at the requested power, making more efficient use of limited capacity.

[0285] Of course, the above-mentioned average distribution method for both the battery storage and charging piles is only a preferred embodiment. In addition, those skilled in the art can also use other distribution methods to distribute power. Such changes in specific distribution methods do not deviate from the principles of this application. For example, the proportion of the requested power at the storage end / pile end to the total requested power at the station end / pile end can also be used for distribution.

[0286] In a possible implementation, the power control method further includes: obtaining the real-time total power of the charging and swapping station; comparing the real-time total power with the power limit; when the real-time total power is greater than the power limit, controlling the total power of the charging and swapping station to be reduced to the power limit. Specifically, under the premise that the battery swapping station is provided with the above-mentioned measurement and control meter, the real-time total power of the charging and swapping station is obtained through the measurement and control meter. The real-time total power is then compared with the power limit. If the real-time total power is greater than the power limit, it proves that the total power of the current charging and swapping station exceeds the power limit, which is likely to cause over-limit tripping and equipment failure. At this time, the difference between the real-time total power and the power limit is calculated, and the total power of the charging and swapping station is controlled to reduce the difference, thereby reducing it to the power limit, so as to avoid the above situation. Among them, the way to reduce the total power can be achieved through the following methods:

[0287] Method 1: After calculating the difference between the real-time total power and the power limit, identify a charging pile / battery compartment whose actual pile / end power is greater than the difference, and then reduce the difference based on the power of the charging pile / battery compartment.

[0288] Method 2: After calculating the difference between the real-time total power and the power limit, the difference is evenly distributed to all charging devices (charging piles + battery compartments), and then the power of all charging devices is controlled to reduce.

[0289] Of course, after the charging pile / battery compartment reduces the power, it will not last long. The power can be redistributed the next time the first control unit interacts with the second control unit.

[0290] By monitoring the real-time total power of the charging and swapping station in real time during power distribution, and controlling the power distribution of the charging and swapping station based on the real-time total power and the power limit, the present application can also strictly distribute power within the power limit, avoiding over-limit operation from the source, and avoiding the tripping, device damage, etc. caused by the total power exceeding the limit of the charging and swapping station when there may be abnormalities in charging piles, battery compartments and other equipment, thereby reducing the operation and maintenance costs of the entire station.

[0291] Of course, when the measurement and control meter is not set up, the real-time total power in the station can also be calculated by obtaining the real-time power of all current battery compartments, electrical equipment and charging piles in the station.

[0292] In one possible embodiment, the power control method also includes: obtaining the communication status of the charging pile; if a charging pile is in a disconnected state, allocating preset power to it; and / or obtaining the communication status of the battery compartment; if a battery compartment is in a disconnected state, deactivating the battery compartment and selecting the battery compartment corresponding to the battery with the highest remaining power in the remaining battery compartments for power allocation.

[0293] For example, during the power allocation process, it is inevitable that some charging piles will be unable to allocate power due to communication failures. In this case, when a charging pile is detected to have lost communication, a preset power can be allocated to that charging pile to avoid the impact of this uncertainty on the overall power allocation strategy. Of course, after allocating the preset power to the charging pile, the preset power needs to be subtracted from the power limit during the next power allocation.

[0294] Similarly, when a battery compartment is disconnected, a preset power can be allocated to the battery compartment in this manner. In addition, when there is an idle battery compartment, the disconnected battery compartment can be deactivated, and the battery compartment with the highest remaining power among the idle battery compartments can be selected for power allocation.

[0295] Through the above control method, the stability of power distribution can be guaranteed, tripping and equipment damage caused by special circumstances can be avoided, and the real-time total power of the charging and swapping station can be strictly limited to below the power limit.

[0296] Refer to the following Figure 3 , describes a possible control process of this application. Figure 3 This is a logic diagram of a possible implementation of the power control method of the charging and swapping station of the present application.

The total requested power Pcr is determined by the sum of the requested power of the charging piles currently providing charging services.

[0310] S214, determine whether Pccmd ≥ Pcr is true. If so, execute steps S215-S217 once; otherwise, if not, execute steps S218-S220.

[0316] S220: Perform secondary distribution on the redundant power of the battery compartment and the redundant power of the charging pile.

[0317] Although the steps in the above embodiment are described in the aforementioned order, those skilled in the art will appreciate that, in order to achieve the effects of this embodiment, the steps do not need to be performed in this order; they can be performed simultaneously (in parallel) or in a reversed order, and these simple variations are within the scope of protection of this application. For example, step S201 and step S202 can be performed simultaneously or in a reversed order.
