Description

Technical Field

[0001] The present application belongs to the technical field of electric vehicle charging and battery replacement, and in particular, relates to a power supply control method, device, storage medium and electronic equipment of a battery replacement station. Background Art

[0002] In recent years, more and more battery swap stations for replacing electric vehicle power batteries have appeared at home and abroad, and vehicles that support battery swap functions are also emerging. When a vehicle needs to replace its power battery, the vehicle that supports battery swap functions drives into the battery swap station when it needs to replace its power battery. The corresponding battery swap mechanism in the battery swap station removes the power battery to be replaced on the vehicle and replaces it with the fully charged power battery in the battery swap station. Compared with the way that vehicles replenish energy through charging, the vehicle battery swap method has the advantages of short replenishment time, automatic replenishment, and more flexible battery charging time.

[0003] At present, during the normal operation of the battery swap station, its own related load equipment such as cooling equipment, monitoring equipment, etc. need to be running all the time. The electricity consumed in the operation is generally taken from the power grid. This power supply method will lead to higher operating costs of the power supply station, especially during peak hours when the power grid has higher electricity prices, which will significantly increase the operating costs of the entire station.

[0070] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0071] At present, during the normal operation of the battery swap station, its own related load equipment such as cooling equipment and monitoring equipment need to be running all the time, and the electricity consumed in the operation is generally taken from the power grid. This power supply method will lead to high operating costs of the power supply station, especially during the peak period of electricity consumption, the power grid with higher electricity charges will significantly increase the operating costs of the entire station. Some existing technologies reduce the operating costs of the battery swap station by adding energy storage equipment. For example, during the valley period, electricity is taken from the grid to charge the energy storage equipment, and during the non-valley period, the valley electricity of the energy storage equipment is used to power the power battery and the battery swap station's own equipment to achieve full utilization of valley electricity. Although this method can reduce the operating costs of the battery swap station to a certain extent, adding energy storage equipment will have a large initial cost investment, the total cost of the battery swap station will be greatly increased, and the complexity of the entire station will be increased. Therefore, there is an urgent need for a more flexible valley electricity maximization solution that does not cause major changes to the overall structure of the battery swap station to achieve low-cost operation of the battery swap station.

[0072] In order to solve at least one of the above technical problems, the embodiments of the present application provide a power supply control method, device, storage medium, electronic device and computer program product for a battery swap station.

[0073] See also Figure 1 and Figure 2 , Figure 1 is a flow chart of a power supply control method for a battery swap station provided in an embodiment of the present application, Figure 2: is a schematic diagram of the architecture of the battery swap station provided in an embodiment of the present application. The power supply control method of the battery swap station is applied to electronic devices, and the power supply control method can be executed by the electronic device or a functional module or functional entity in the electronic device. The battery swap station 10 includes a plurality of power batteries 11 (for example, N power batteries) and a load device 12. The load device 12 is mainly used to maintain the normal operation of the battery swap station 10, which includes but is not limited to cooling equipment, monitoring equipment, etc. A switch module 13 is provided between the battery swap station 10 and the power grid 20. When the switch module 13 is in a closed state, the power grid 20 and the battery swap station 10 are connected, and the power grid 20 can supply power to the battery swap station 10, such as the power battery 11 and the load device 12 in the battery swap station 10. When the switch module 13 is in an open state, the power grid 20 and the battery swap station 10 are disconnected, and the power grid 20 cannot supply power to the battery swap station 10. Usually during the trough period, the power battery 11 and the load device 12 in the battery swap station 10 can be powered by the power grid 20, and the fully charged power battery 11 can subsequently provide battery swap services to the car during the peak period and the parity period.

[0074] During the actual operation of the battery swap station 10, we found that many battery swap stations 10 often have the problem of low battery swap frequency, that is, the fully charged power battery 11 at the trough cannot be completely swapped to the car, and the load equipment 12 in the battery swap station 10 needs to draw power from the power grid 20 to maintain operation. In this way, on the one hand, the valley electricity in the power battery 11 in the battery swap station 10 cannot be fully utilized, and on the other hand, the cost of electricity consumed by the operation of the battery swap station 10 itself is relatively high, especially in the peak stage. In response to this phenomenon, the present application designs a power supply control method for the battery swap station 10, which can achieve low-cost operation of the battery swap station 10 by maximizing the utilization of valley electricity without changing the overall structure of the battery swap station 10.

[0075] The power supply control method of the battery swap station 10 can be executed by the processor 14 in the battery swap station 10. The processor 14 is the core control part of the entire battery swap station 10, and mainly provides analysis, coordination, control and other functions. The method specifically includes the following steps 101-104, wherein:

[0076] 101. Obtain historical operation information of the battery swap station, where the historical operation information includes historical battery swap information of the power battery and historical power consumption of the load equipment within at least one target period, where the target period is the period between two adjacent trough periods and includes at least one peak period and at least one parity period.

[0077] Among them, the peak period refers to the time period of the day when the electricity demand is the highest. During this period, the power load reaches the peak because a large number of users use electricity at the same time. The parity period refers to the time period when the electricity demand is relatively stable and the electricity price is at a normal level. During this period, the power load is relatively low and the electricity price is relatively stable. The trough period refers to the time period when the electricity demand is the lowest. During this period, the power load is reduced to the lowest because a large number of users reduce their electricity use.

[0078] The historical operation information may be the actual operation information of the battery swap station 10 for at least one day during the previous operation. The target period is a non-trough period, which is composed of a peak period and a par period, and mainly refers to a period composed of all peak periods and par periods between two adjacent trough periods. For example, if the peak period is 08:30-11:30 and 18:00-23:00, the par period is 07:00-08:30 and 11:30-18:00, and the trough period is 23:00-7:00, then the target period is 7:00-23:00.

[0079] 102. Based on the historical battery replacement information, estimate the target power battery 11 and available reserve power that can supply power to the load device 12 in the next target period.

[0080] Among them, the target power battery 11 is the power battery 11 that is unlikely to be replaced within the next target period (which can be considered as the upcoming non-valley period), and the available reserve power is the power that is likely to be used to power the battery swap station 10 within the next target period. They are all predicted based on the actual historical operation information of the battery swap station 10.

[0081] In some embodiments, see Figure 3 , Figure 3 1 is another flow chart of the power supply control method of the battery swap station 10 provided in an embodiment of the present application. The above step 102 specifically includes:

[0082] 1021. Determine the power batteries that have not been replaced in each previous target time period based on the historical battery replacement information as candidate power batteries, and count the number of times each candidate power battery has not been replaced.

[0083] 1022. According to the power level of each candidate power battery and the number of times the battery has not been replaced, estimate the target power battery and the available reserve power that can supply power to the load device in the next target period.

[0084] Furthermore, the above step 1022 specifically includes:

[0085] Calculate the sum of the power of all candidate power batteries in each target period to obtain a total power sum value, and each target period corresponds to a total power sum value;

[0086] Calculate the average of all total power and values, and use the average as the estimated available reserve power that can power the load device in the next target period;

[0087] The candidate power batteries are sorted in descending order according to the number of times they have not been replaced, and a preset number of candidate power batteries are selected as the target power batteries that are estimated to be able to power the load device in the next target period.

[0088] Among them, the power batteries 11 that have never been replaced during the non-valley period of at least one day in the past (i.e., the above-mentioned target period) are statistically analyzed, and the total power and value of these power batteries 11 counted each time are calculated. If only one day of historical data is statistically analyzed, the power batteries 11 that have not been replaced are directly used as target batteries, and the total power and value are used as available reserve power. If multiple days of historical data are statistically analyzed to improve the prediction accuracy, multiple power batteries 11 that have not been replaced the most times can be selected as target batteries, and the average of the total power and value can be used as the available reserve power.

[0089] 103. According to the historical power consumption, estimate the first power consumption demand of the load device during the peak period and the second power consumption demand during the parity period in the next target period.

[0090] In some embodiments, see Figure 3 , the above step 103 specifically includes:

[0091] 1031. Determine, based on the historical power consumption, a first power consumption consumed by the load device 12 during the peak period in each target period and a second power consumption consumed during the parity period;

[0092] 1032. Calculate the average value of all first power consumptions, and use the corresponding average value as the estimated first power demand of the load equipment during the peak period in the next target period; calculate the average value of all second power consumptions, and use the corresponding average value as the estimated second power demand of the load equipment during the parity period in the next target period.

[0093] For example, the power demand of the load device 12 in the peak period of the next one or more days can be analyzed and estimated based on the actual power consumption of the load device 12 in the peak period in the last at least one day, and the power demand of the load device 12 in the parity period in the last at least one day can be analyzed and estimated. Specifically, the average power consumption of the load device 12 in the peak period of the last at least one day and the average power consumption of the load device 12 in the parity period of the last at least one day can be calculated respectively, and the average power consumption of the load device 12 in the subsequent corresponding period can be used as the power demand of the load device 12.

[0094] 104. Control the target power battery to supply power to the load device in a next target time period according to the available reserve power, the first required power consumption, and the second required power consumption.

[0095] In some embodiments, please see Figure 3 , the above step 104 specifically includes:

[0096] 1041. Calculate the sum of the first power demand and the second power demand to obtain a total power demand.

[0097] 1042. Generate a load power supply strategy corresponding to the next target time period according to the available reserve power, the first demand power consumption, the second demand power consumption, the total demand power consumption, the target power battery and the power grid.

[0098] The load power supply strategy is mainly used to set the power supply mode of the load device 12 during the non-valley period of the next day or multiple days, such as when the power grid 20 supplies power and when the target power battery 11 supplies power. For the valley period of the next day or multiple days, the load device 12 can be powered by the power grid 20 or other power supply modes, which are not limited here.

[0099] Furthermore, the above step 1042 may include:

[0100] When the available reserve power is less than the first required power consumption, a first load power supply strategy is generated, wherein the first load power supply strategy is used to indicate that in the next target period, the target power battery is used to first supply power to the load device, and when the power of the target power battery is exhausted, the power grid is used to supply power to the load device;

[0101] When the available reserve power is greater than or equal to the first required power consumption but less than the total required power consumption, a second load power supply strategy is generated, the second load power supply strategy is used to indicate that in the next target period, the target power battery is used to supply power to the load device during the peak period, and the remaining power of the target power battery is used to supply power to the load device during the parity stage, and when the remaining power is insufficient, the power grid continues to supply power to the load device;

[0102] When the available reserve power is greater than or equal to the total required power consumption, a third load power supply strategy is generated, so the third load power supply strategy is used to indicate that the load device is powered by the target power battery during the peak period and the parity period of the next target period.

[0103] That is, assuming that after statistical analysis of historical operation information, the available reserve power of the non-valley period (i.e., the above-mentioned target period) is estimated to be E1, the first demand power consumption during the peak period is E2, and the second demand power consumption during the flat price period is E3. At this time, a comparative analysis is performed on the magnitudes of E1, E2, and E3. If E1 < E2, then subsequently, during the non-valley period, the power of the target power battery 11 (i.e., the estimated power battery 11 that has not been replaced) is preferentially used to supply power to the load device 12, and after its power is used up, the power grid 20 is used for power supply; if (E2 + E3) > E1 ≥ E2, then subsequently, the power consumption of the load device 12 during the peak period is entirely from the target power battery 11. If there is remaining power in the target power battery 11, it is used to supply power to the load device 12 during the flat price period. When the remaining power is insufficient, the power grid 20 urgently supplies power to the load device 12; if E1 ≥ (E2 + E3), then subsequently, the power supply of the load device 12 during the peak period and the flat price period is both from the target power battery 11, and there is no need to draw power from the power grid 20.

[0104] 1043. According to this load power supply strategy, control the target power battery to supply power to the load device within the next target period.

[0105] Among them, when implementing the load power supply strategy, it involves the switching of the power supply object of the load device 12. For example, if the power of the target power battery 11 is sufficient, the power supply object for the load device 12 can be switched from the power grid 20 to the target power battery 11. If the power of the target power battery 11 is insufficient, the power supply object for the load device 12 can be switched from the target power battery 11 to the power grid 20 to ensure that the load device 12 is not powered off at any time and to ensure the normal operation of the battery swapping station 10. This switching can be based on Figure 2 the switch module 13 and the charge and discharge control module shown in

[0106] That is, the battery swapping station 10 further includes a switch module 13 and a plurality of charge and discharge control modules 15. The charge and discharge control module 15 is connected to the corresponding power battery 11 one-to-one and is used to control the corresponding power battery 11 to charge or discharge; one end of the switch module 13 is connected to the power grid 20, and the other end is connected to the charge and discharge control module 15 and the load device 12. At this time, the above step 1043 further includes:

[0107] Within the next target period, control the switch state of the switch module and the working mode of the charge and discharge control module according to this power supply strategy, so that the target power battery and the power grid supply power to the load device in a switching manner.

[0108] Among them, the switch module 13 has two states, open and closed. It is arranged between the power grid 20 and the battery swap station 10. When it is necessary to draw power from the power grid 20, the switch module 13 needs to be in a closed state. And to prevent reverse work, when it is not necessary to draw power from the power grid 20, such as during non-valley periods, when it is only necessary to power the load device 12 through the target power battery 11, the switch module 13 can be in an open state. The charge and discharge control module 15 includes but is not limited to a bidirectional charger with charge and discharge capabilities, which includes at least two working modes: a charge control mode and a discharge control mode. The charge and discharge control module 15 cannot work in the charge control mode and the discharge control mode at the same time. In the charge control mode, the charge and discharge control module 15 can draw power from the power grid 20 to charge the corresponding power battery 11. In the discharge control mode, the charge and discharge control module 15 can draw power from the corresponding power battery 11 to output AC power to the outside.

[0109] Specifically, the process of switching to the target power battery 11 to supply power to the load device 12 is as follows: first, the charge and discharge control module 15 corresponding to the target power battery 11 is selected to make it work in the discharge control mode, and the frequency and phase are adjusted by the charge and discharge control module 15 to connect to the power grid 20. After the connection is completed, the charge and discharge control module 15 gradually transfers the power supply of the load device 12 from the power grid 20 to the target power battery 11. When the transfer is completed, the control switch module 13 is in the open state to cut off the power supply of the power grid 20, and the switching is completed. The process of switching to the power grid 20 to supply power to the load device 12 is as follows: the charge and discharge control module 15 adjusts the frequency, phase, etc. to prepare for the connection before the connection. After the connection conditions are met, the control switch module 13 is in the closed state, and the charge and discharge control module 15 gradually transfers the power supply of the load device 12 from the target power battery 11 to the power grid 20. After the transfer is completed, the charge and discharge control module 15 turns off its power output, and the switching is completed.

[0110] From the above, it can be seen that the power supply control method of the battery swap station provided in the embodiment of the present application obtains historical operation information of the battery swap station, and the historical operation information includes historical battery swap information of the power battery in at least one target time period and historical power consumption of the load equipment, the target time period is the time period between two adjacent valley periods, and includes at least one peak period and at least one parity period; according to the historical battery swap information, the target power battery and the available reserve power that can power the load equipment in the next target time period are estimated; according to the historical power consumption, the first demand power consumption of the load equipment in the peak period and the second demand power consumption in the parity period in the next target time period are estimated; according to the available reserve power, the first demand power consumption and the second demand power consumption, the target power battery is controlled to power the load equipment in the next target time period, that is, according to the historical operation information, the battery valley power that can be provided to the battery swap station in the non-valley period in the future is estimated, and the battery valley power is used to power the battery swap station in the non-valley period, thereby maximizing the utilization of valley power without improving the overall structure of the battery swap station, reducing the amount of power taken from the power grid, and realizing low-cost operation of the battery swap station with high flexibility and strong practicality.
