Description

[0002] In recent years, more and more battery swapping stations for replacing power batteries of electric vehicles have appeared at home and abroad, and vehicles supporting battery swapping function are also emerging. When the vehicle needs to be replaced, the vehicle supporting the battery swapping function drives into the battery swapping station when it needs to replace the power battery, and the corresponding battery swapping mechanism in the battery swapping station takes down the power battery to be replaced on the vehicle and replaces it with a power battery that has been fully charged in the battery swapping station. Compared with the way of supplementing energy by charging, the way of vehicle battery replacement has the advantages of short energy supplement time, automatic energy supplement, flexible battery charging time, etc.

DETAILED DESCRIPTION

[0070] The embodiments of the present application are described in detail below, examples of which are shown in the accompanying drawings, wherein the same or similar notations represent the same or similar elements having the same or similar functions throughout. The embodiments described below by reference to the drawings are exemplary only, for the purpose of explanation, and are not to be understood as a limitation of the present application.

[0071] At present, in the normal operation process of the battery swap station, its own related load devices such as cooling devices, monitoring devices, etc. need to run all the time, and the electric energy consumed by the operation is generally taken from the power grid. This power supply mode will cause the operation cost of the power supply station to be relatively high, especially the power grid taking power during the peak power consumption period will significantly increase the operation cost of the whole station. Some existing technologies reduce the operation cost of the battery swap station by increasing energy storage devices, such as taking power from the power grid to charge the energy storage devices during the trough period, and using the trough power of the energy storage devices to supply power to the power battery and the battery swap station itself during the non-trough period, to realize the full utilization of trough power. Although this method can reduce the operation cost of the battery swap station to a certain extent, the initial cost investment of the energy storage device will be relatively large, the total cost of the battery swap station will be greatly increased, and the complexity of the whole station will be increased. Therefore, there is an urgent need for a trough power maximization utilization scheme that is more flexible and does not cause great changes to the overall structure of the battery swap station, to realize the low-cost operation of the battery swap station.

[0072] To solve the above at least one technical problem, the present application provides a power supply control method, device, storage medium, electronic device and computer program product of a battery swap station.

[0073] Please refer to Figure 1 and Figure 2 , Figure 1 is a flowchart of the power supply control method of the battery swap station provided by the embodiments of the present application, Figure 2FIG. 1 is a schematic diagram of an architecture of a battery swap station provided by an embodiment of the present application. The power supply control method of the battery swap station is applied to an electronic device, and 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 (such as 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, and includes but is not limited to a cooling device, a monitoring device, and the like. A switch module 13 is arranged between the battery swap station 10 and a 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 supplying power to the power batteries 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. Generally, in a trough period, the power batteries 11 and the load device 12 in the battery swap station 10 can be supplied with power by the power grid 20, and the fully charged power batteries 11 can subsequently provide battery swap services for vehicles in a peak period and a flat rate period.

[0074] In the actual operation of the battery swap station 10, it is found that many battery swap stations 10 often have a low battery swap frequency, that is, the trough charged power batteries 11 cannot be completely swapped to vehicles, and the load device 12 in the battery swap station 10 needs to be powered by the power grid 20 at all times to maintain operation. Thus, on the one hand, the trough power in the power batteries 11 in the battery swap station 10 cannot be fully utilized, and on the other hand, the power cost for the operation of the battery swap station 10 itself is relatively high, especially in the peak period. In view of this phenomenon, the present application designs a power supply control method of a battery swap station 10, which can realize low-cost operation of the battery swap station 10 by maximizing the utilization of trough power 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 a processor 14 in the battery swap station 10. The processor 14 is a core control part of the entire battery swap station 10, and mainly provides analysis, coordination, control, and the like. The method specifically includes the following steps 101-104.

[0076] 101. Obtain historical operation information of the battery swap station. The historical operation information includes historical battery swap information of the power batteries and historical power consumption of the load device in at least one target period. The target period is a period between two adjacent trough periods, and includes at least one peak period and at least one flat rate period.

[0077] The peak period refers to a time period in a day when the power demand is the highest. In this period, the power load reaches the peak value due to the simultaneous use of power by a large number of users. The flat rate period refers to a time period when the power demand is relatively stable and the electricity price is at a normal level. In this period, the power load is relatively low, and the electricity price is relatively stable. The valley period refers to a time period when the power demand is the lowest. In this period, the power load is reduced to the lowest due to the reduction of power use by a large number of users.

[0078] The historical operation information can be actual operation information of the battery swap station 10 in a past operation period of at least one day. The target period is a non-valley period, which is composed of a peak period and a flat rate period, and mainly refers to a period composed of all peak periods and flat rate periods between adjacent two valley periods. For example, if the peak period is 08:30-11:30 and 18:00-23:00, the flat rate period is 07:00-08:30 and 11:30-18:00, and the valley period is 23:00-7:00, the target period is 7:00-23:00.

[0079] 102、According to the historical battery swap information, the target power battery 11 that can supply power to the load device 12 in the next target period and the available reserve power are estimated.

[0080] The target power battery 11 is a power battery 11 that is not likely to be swapped in the next target period (which can be considered as an upcoming non-valley period), and the available reserve power is the power that can be used to supply power to the battery swap station 10 in the next target period. They are both predicted based on the actual historical operation information of the battery swap station 10.

[0081] In some embodiments, referring to Figure 3 , Figure 3 is another flowchart of the power supply control method of the battery swap station 10 provided by the embodiments of the present application, and the step 102 specifically includes:

[0082] 1021, according to the historical battery swap information, determine the power battery that is not swapped in each target period in the past as a candidate power battery, and count the number of times each candidate power battery is not swapped.

[0083] 1022, according to the power of each candidate power battery and the number of times it is not swapped, estimate the target power battery that can supply power to the load device in the next target period and the available reserve power.

[0084] Further, the 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] calculating an average of all total power sums and using the average as an estimated available reserve power for powering the load device in the next target period;

[0087] ranking the candidate power batteries in descending order of the number of times of not being replaced, and selecting a preset number of candidate power batteries as target power batteries estimated to be able to power the load device in the next target period.

[0088] The statistical analysis is performed on the power batteries 11 that have never been replaced in the past at least one day of non-valley period (i.e. the target period described above), and the total power sum of these power batteries 11 is calculated each time. If only one day of historical data is statistically analyzed, the power batteries 11 that have never been replaced are directly used as target batteries, and the total power sum is directly used as the available reserve power. If more days of historical data are statistically analyzed to improve the prediction accuracy, a plurality of power batteries 11 with the largest number of times of not being replaced can be selected as target batteries, and the average of the total power sums is used as the available reserve power.

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

[0090] In some embodiments, please continue to refer to Figure 3 The step 103 specifically includes:

[0091] 1031. According to the historical power consumption, the first power consumption in the peak period and the second power consumption in the flat period of the load device 12 in each target period are determined;

[0092] 1032. The average of all first power consumptions is calculated, and the corresponding average is used as the estimated first demand power consumption of the load device in the peak period in the next target period. The average of all second power consumptions is calculated, and the corresponding average is used as the estimated second demand power consumption of the load device in the flat period in the next target period.

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

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

[0095] In some embodiments, please continue to refer to Figure 3 The step 104 specifically includes:

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

[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, the second demand power, the total demand power, 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 in the non-valley period of the future one or more days, such as when to be powered by the power grid 20 and when to be powered by the target power battery 11. For the valley period of the future one or more days, the load device 12 can be powered by the power grid 20, or other power supply modes can be used, which are not limited here.

[0099] Further, the step 1042 can include:

[0100] When the available reserve power is less than the first demand power, a first load power supply strategy is generated, which is used to instruct to supply power to the load device by the target power battery in the next target time period, and when the power of the target power battery is exhausted, to supply power to the load device by the power grid;

[0101] When the available reserve power is greater than or equal to the first demand power but less than the total demand power, a second load power supply strategy is generated, which is used to instruct to supply power to the load device by the target power battery in the peak period, and to supply power to the load device by the remaining power of the target power battery in the flat period, and when the remaining power is not enough, to continue to supply power to the load device by the power grid in the next target time period;

[0102] When the available reserve power is greater than or equal to the total demand power, a third load power supply strategy is generated, so the third load power supply strategy is used to instruct to supply power to the load device by the target power battery in the peak period and the flat period of the next target time period.

[0103] That is, assuming that the estimated available reserve power of the non-valley period (i.e. the target period described above) is E1, the first demand power of the peak period is E2, and the second demand power of the flat rate period is E3 after statistical analysis of historical operation information, at this time, the sizes of E1, E2 and E3 are compared and analyzed, if E1 < E2, then in the subsequent non-valley period, the target power battery 11 (i.e. the estimated power battery 11 that is not replaced) is preferentially used to power the load device 12, and after its power is used up, the power grid 20 is used to power; if (E2+E3) > E1 ≥ E2, then in the subsequent peak period, the power of the load device 12 comes entirely from the target power battery 11, and if the target power battery 11 has remaining power, it is used to power the load device 12 in the flat rate period, and when the remaining power is not enough, the power grid 20 is used to urgently power the load device 12; if E1 ≥ (E2+E3), then in the subsequent peak period and flat rate period, the power of the load device 12 comes from the target power battery 11, and no power is taken from the power grid 20.

[0104] 1043. According to the load power supply strategy, the target power battery is controlled to supply power to the load device in the next target period.

[0105] Wherein, in the execution of the load power supply strategy, the switching of the power supply object of the load device 12 is involved, such as if the power of the target power battery 11 is sufficient, the power supply object of the load device 12 can be switched from the power grid 20 to the target power battery 11, and if the power of the target power battery 11 is insufficient, the power supply object of 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 continuously powered at any time, and to ensure the normal operation of the battery swap station 10. This switching can be realized based on the switching module 13 and the charge and discharge control module shown in Figure 2 .

[0106] That is, the battery swap station 10 further comprises a switching module 13 and a plurality of charge and discharge control modules 15, the charge and discharge control module 15 and the power battery 11 are connected one by one, for controlling the corresponding power battery 11 to charge or discharge; one end of the switching 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 step 1043 further comprises:

[0107] In the next target period, the switching state of the switching module and the working mode of the charge and discharge control module are controlled according to the power supply strategy, so that the target power battery and the power grid supply power to the load device through switching.

[0108] The switch module 13 has two states of opening and closing, and is arranged between the power grid 20 and the battery swap station 10. When power needs to be taken from the power grid 20, the switch module 13 needs to be in a closed state. To prevent reverse power, when power does not need to be taken from the power grid 20, such as in a non-valley period, only the target power battery 11 is used to supply power to the load device 12, and the switch module 13 is in an open state. The charge and discharge control module 15 includes but is not limited to a bidirectional charger with charge and discharge capability, and at least includes 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 take power from the power grid 20 to charge the corresponding power battery 11, and in the discharge control mode, the charge and discharge control module 15 can take power from the corresponding power battery 11 to output AC power.

[0109] Specifically, the process of switching to the target power battery 11 to supply power to the load device 12 is as follows: first, select the charge and discharge control module 15 corresponding to the target power battery 11 to work in the discharge control mode, adjust the frequency, phase and grid 20 through the charge and discharge control module 15. After grid 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, control the switch module 13 to be in an open state to cut off the power supply of the power grid 20. At this time, the switching is completed. The process of switching to the power grid 20 to supply power to the load device 12 is as follows: adjust the frequency, phase and other grid connection preparation through the charge and discharge control module 15, and after the grid connection condition is met, control the switch module 13 to be in a closed state. 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 closes its power output. At this time, the switching is completed.

[0110] From the above, the power supply control method of the battery swap station provided by the embodiments of the present application is known, the historical operation information of the battery swap station is obtained, the historical operation information includes historical battery swap information of the power battery and historical power consumption of the load device in at least one target period, the target period is a period between two adjacent trough periods, and includes at least one peak period and at least one flat rate period; according to the historical battery swap information, the target power battery that can supply power to the load device in the next target period and the available reserve power are estimated; according to the historical power consumption, the first demand power consumption of the load device in the peak period and the second demand power consumption in the flat rate period in the next target 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 supply power to the load device in the next target period, that is, according to the historical operation information, the subsequent battery trough power that can be provided for the battery swap station in the non-trough period is estimated, and the battery trough power is used to supply power to the battery swap station in the non-trough period, so that the maximization utilization of the trough power can be realized without improving the overall structure of the battery swap station, the power amount taken from the power grid is reduced, the low-cost operation of the battery swap station is realized, the flexibility is high, and the practicability is strong.
