[0002] With the rapid development of new energy vehicles, the demand for energy replenishment of automotive battery packs is becoming more and more diversified. As an energy station that provides charging and rapid replacement of power batteries for electric vehicles, the concentration of charging and swapping stations proposed in related technologies is relatively low, and the construction of swapping stations and fast charging stations involves "land use" and "electricity use". The approval and filing process is long, the power capacity is difficult to increase, and the cost is high. That is, only with a certain construction area and power supply can the growing demand for charging and swapping of electric vehicles be met. At the same time, the main working hours of the charging facilities of the charging station are mostly concentrated at night, and the idle rate is high during the day. The main working hours of the swapping station are concentrated during the day. The charging facilities of the swapping station work mainly during the day and are idle at night. The charging facilities of the swapping station in the related technology have no power output at night, and the charging facilities of the charging station have no power output or output at a lower power during the day, which makes the resource utilization rate extremely low.

[0035] Embodiments of the present invention are described in detail below, examples of which 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 intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0036] The following describes a control method for a charging and swapping station, a charging and swapping station, and a storage medium according to an embodiment of the present invention with reference to the accompanying drawings.

[0037] Figure 1 4 is a flow chart of a control method of a charging and swapping station according to an embodiment of the present invention.

[0038] It should be noted that the charging and swapping stations shown in the following embodiments of the present invention include a charging station and a swapping station, and the charging station and the swapping station share multiple charging devices.

[0039] like Figure 1 As shown, in some embodiments, the control method of the charging and swapping station may include:

[0040] S101, obtaining the occupancy status of multiple charging devices occupied by vehicles in the charging station, and determining the storage locations of low-charged battery packs and fully-charged battery packs in the battery swap station.

[0041] In some embodiments of the present invention, to determine whether multiple charging devices are occupied by vehicles in the charging station, the occupancy status of the corresponding parking spaces in the charging station can be detected by a parking space detection device to obtain the detection result, and the corresponding LED lights and other color display devices are used for display according to the detection result. Among them, different colors of LED lights and other color display devices represent different parking space states. For example, a red light represents that there is a vehicle in the charging station at the current moment, and the charging device is in an occupied state. A green light represents that there is no vehicle in the charging station at the current moment, and the charging device is not occupied and is in an idle state. It should be noted that the method for obtaining the occupancy status of multiple charging devices occupied by vehicles in the charging station shown above is only exemplary. In real life, other forms such as voice and icons can also be used to indicate that the charging device is occupied by vehicles in the charging station at the current moment. It can be selected according to the actual situation, and no specific restrictions are made in the embodiments of the present invention.

[0042] Exemplarily, since a battery swap station may include multiple battery packs, in order to determine whether each battery pack is a low-charge battery pack or a fully-charged battery pack, the low-charge amount of each battery pack in the battery swap station may be detected, and the low-charge state of the corresponding battery pack may be judged based on the low-charge amount, thereby determining the storage locations of the corresponding low-charge battery packs and the fully-charged battery packs in the battery swap station.

[0043] S102, determining the rechargeable battery packs and the charging devices thereof according to the occupancy status, the storage locations of the fully-charged battery packs, and the storage locations of the depleted battery packs.

[0044] It is understandable that since the charging station and the battery swap station in the embodiment of the present invention share the charging device, when a low-charge battery pack needs to be charged, it is necessary to first ensure that the charging device for charging the low-charge battery pack will not be occupied by vehicles for charging. Therefore, it is necessary to first determine the occupancy status of vehicles in the charging station according to step S101, and then determine the location where the low-charge battery pack can be charged based on the occupancy status, the storage location of the fully-charged battery pack, and the storage location of the low-charged battery pack.

[0045] S103, respectively determining the charging current of each rechargeable battery pack, and controlling the corresponding charging device to charge the corresponding rechargeable battery pack according to each charging current.

[0046] Optionally, in this embodiment, for different rechargeable battery packs, the charging current used by the charging device to charge them may also be different.

[0047] According to the control method of the charging and swapping station of the embodiment of the present invention, the charging station and the swapping station included in the charging and swapping station share multiple charging devices, which can save half of the charging devices, reduce the achievable cost, and reduce resource waste. At the same time, the method proposes to determine the rechargeable battery pack and its charging position according to the occupancy of the charging device by the vehicle in the charging station, the location of the fully charged battery pack and the location of the low-charged battery pack, and charge the rechargeable battery pack according to the charging current of the rechargeable battery pack, so that the method can ensure the normal charging of each rechargeable battery pack on the basis of ensuring the reliable operation of the charging and swapping station, thereby achieving mutual coordination between the charging station and the swapping station.

[0048] As a possible implementation, Figure 2 As shown, in the above embodiment, determining the rechargeable battery pack and its charging device according to the occupancy status, the storage location of the fully charged battery pack, and the storage location of the low-charged battery pack may specifically include:

[0049] S201, judging whether the charging device at the storage location where each low-power battery pack is located is occupied by a vehicle in the charging station according to the occupancy status.

[0050] S202: If there is a low-power battery pack whose charging device is not occupied in the storage location, determine that the low-power battery pack is a rechargeable battery pack, and determine that the charging device in the storage location where the low-power battery pack is located is a charging device for rechargeable battery packs.

[0051] Specifically, since the charging station and the battery swap station in the embodiment of the present invention share a charging device, when charging a low-power battery pack, it is necessary to first determine whether the charging device at the storage location where the low-power battery pack is located is occupied by vehicles in the charging station based on the occupancy status of the vehicles in the charging station. If it is not occupied, it can be determined that the charging device can charge the low-power battery pack at the current moment, that is, the low-power battery pack is used as a rechargeable battery pack. The charging device at the storage location where the rechargeable battery pack is located is further used to charge it with the charging current determined according to step S103, that is, the charging device at the storage location where the low-power battery pack is located is used as the charging device for the rechargeable battery pack.

[0052] In this implementation, the rechargeable battery pack and its charging device are determined according to the occupancy status, the storage location of the fully charged battery pack, and the storage location of the low-charged battery pack, and the following may also be included:

[0053] S203: If there is a low-charged battery pack whose charging device is occupied in the storage location, it is determined whether the charging devices in the storage locations where the fully-charged battery packs are located are occupied by vehicles in the charging station according to the occupancy status.

[0054] S204, if there is a fully charged battery pack whose charging device is not occupied in a storage location, the fully charged battery pack is swapped with a low-charged battery pack whose charging device is occupied in a storage location, and the low-charged battery pack is determined to be a rechargeable battery pack, and the charging device in the storage location where the low-charged battery pack is located after the storage location swap is determined to be a charging device for a rechargeable battery pack.

[0055] Specifically, when judging whether the charging device of the storage position where the low-charged battery pack is located is occupied by the vehicle in the charging station according to the occupancy status of the vehicles in the charging station, if there is a low-charged battery pack whose charging device is occupied, since the fully-charged battery pack does not need to be charged, it can be judged whether the charging devices of the storage positions where the fully-charged battery packs are located in the battery swap station are occupied by the vehicles in the charging station. If there is a fully-charged battery pack whose charging device is not occupied, the fully-charged battery pack can be controlled to exchange the storage position with the low-charged battery pack whose charging device is occupied in a storage position, and further use the charging device at the storage position where the low-charged battery pack is located after the exchange to charge it with the charging current determined according to step S103.

[0056] Optionally, in some examples of the present invention, if it is determined according to the judgment process in the above implementation that a fully-charged battery pack needs to be exchanged with a low-charged battery pack whose charging device is occupied in a storage location, an exchange instruction can be sent to the battery swapping robot in the charging and swapping station. After receiving the exchange instruction, the battery swapping robot compares the storage location information corresponding to each low-charged battery pack and each fully-charged battery pack, takes out the fully-charged battery pack, and puts the low-charged battery pack in place, thereby realizing the storage location exchange between the fully-charged battery pack and the low-charged battery pack whose charging device is occupied in a storage location. It should be noted that the above-mentioned method of exchanging the storage locations of fully-charged battery packs and low-charged battery packs by the battery swapping robot is only exemplary and does not serve as a limitation to the embodiments of the present invention.

[0057] Furthermore, as a possible implementation method, Figure 3 As shown, after the rechargeable battery packs and their charging devices are determined, the charging currents of the rechargeable battery packs can be determined respectively, which may include:

[0058] S301, obtain the historical battery swap data and benchmark battery swap frequency of the battery swap station, and obtain the charging benchmark current of each rechargeable battery pack.

[0059] It should be noted that the reference battery replacement frequency in the embodiment of the present invention is the maximum number of battery replacements that can be made within one hour under ideal operating conditions of the battery replacement station, which is the minimum value between the number of battery packs that can be fully charged per hour and the number of battery packs that can be replaced per hour; the charging reference current is the minimum value between the maximum allowable charging current of the rechargeable battery pack in the battery replacement station and the maximum output current of the charging device of the rechargeable battery pack, wherein the maximum output current of the charging device can be determined according to the output power of the charging device, and the output power can be selected according to actual needs.

[0060] S302, obtaining the charging current of each rechargeable battery pack based on historical battery replacement data, benchmark battery replacement frequency, occupancy status and charging benchmark current of each rechargeable battery pack.

[0061] As a feasible implementation method, Figure 4 As shown, the charging current of each rechargeable battery pack is obtained according to the historical battery replacement data, the benchmark battery replacement frequency, the occupancy status and the charging benchmark current of each rechargeable battery pack, which may specifically include:

[0062] S401, obtaining the battery swap frequency influencing factor of the battery swap station based on the historical battery swap data and the benchmark battery swap frequency, and obtaining the charging device occupancy influencing factor of the charging station based on the occupancy situation.

[0063] S402, obtaining the charging current of each rechargeable battery pack according to the influencing factor of the battery swapping frequency at the battery swapping station, the influencing factor of the charging device occupied by the charging station and the charging reference current of each rechargeable battery pack.

[0064] That is to say, when determining the charging current of a rechargeable battery pack, in addition to considering the influencing factors within the battery swap station, such as the battery swap frequency at the battery swap station and the charging reference current of the rechargeable battery pack, it is also necessary to consider the impact of the charging station occupying the charging device.

[0065] In some embodiments of the present invention, Figure 5 As shown, the control method of the charging and swapping station may also include:

[0066] S501, obtaining the health status of each rechargeable battery pack.

[0067] It is understandable that the battery health condition represents the current battery's ability to store electrical energy relative to a new battery. During the use of the battery pack, factors such as temperature, charge and discharge rate, and battery charge and discharge depth may affect the health condition of the battery pack. The health condition of the battery pack is directly related to the power supply performance of the battery pack. Therefore, before charging it, you must first determine the health condition of the rechargeable battery pack.

[0068] S502, obtaining a lifespan influencing factor of each rechargeable battery pack according to each health condition.

[0069] Exemplarily, the life impact factor of each rechargeable battery pack can be determined according to the battery pack capacity or the battery pack power. Specifically, the life impact factor of the rechargeable battery pack can be determined according to the current capacity of the battery pack and the rated capacity of the battery pack, or according to the current power of the battery pack and the rated power of the battery pack.

[0070] As an example, the life impact factor of a rechargeable battery pack can be calculated by the following formula:

[0071]

[0072] Among them, β is the factor affecting battery life, C aged is the current capacity of the battery pack, C rated is the rated capacity of the battery pack.

[0073] As an example, the life impact factor of a rechargeable battery pack can also be calculated by the following formula:

[0074]

[0075] Among them, Q aged-max is the current maximum discharge capacity of the battery pack, Q new-max Rated discharge capacity for new battery pack.

[0076] S503, obtaining the charging current of each rechargeable battery pack according to the influencing factor of the battery swapping frequency at the battery swapping station, the influencing factor of the charging device occupied at the charging station, and the charging reference current and life influencing factor of each rechargeable battery pack.

[0077] In some embodiments of the present invention, Figure 6 As shown, the control method of the charging and swapping station may also include:

[0078] S601, obtaining a corresponding electricity price influencing factor according to the current power supply period of the power grid.

[0079] It is understandable that the current peak-valley time-of-use electricity price refers to dividing 24 hours a day into multiple time periods such as peak, flat section, and valley according to the load changes of the power grid. Different electricity prices are set by the government departments in charge to encourage electricity users to arrange electricity use time reasonably. As an example, the power grid is divided into four stages: valley, flat section, peak, and peak. In this example, the valley time period is 00:00-8:00, the flat section time period is 8:00-14:00, the peak time period is 14:00-16:00, and the peak time period is 16:00-24:00. Each stage corresponds to an electricity price impact factor, specifically, the valley time period electricity price impact factor is 1, the flat section time period electricity price impact factor is 0.9, the peak time period electricity price impact factor is 0.7, and the peak time period electricity price impact factor is 0.5. It should be noted that the values ​​of the electricity price impact factors shown above are only exemplary. In actual applications, they can be adaptively adjusted according to specific needs, and no specific restrictions are made in the embodiments of the present invention.

[0080] S602, obtaining the charging current of each rechargeable battery pack according to the influencing factor of the battery swapping frequency at the battery swapping station, the influencing factor of the charging device occupied at the charging station and the influencing factor of the electricity price, as well as the charging reference current and the influencing factor of the life of each rechargeable battery pack.

[0081] As an example, for the Nth rechargeable battery pack, the charging current of the Nth rechargeable battery pack is obtained by the following formula:

[0082] CE_IN=min(Basic_IN×α×βN×γ×η, Basic_IN),

[0083] Among them, CE_IN is the charging current of the Nth rechargeable battery pack, Basic_IN is the charging reference current of the Nth rechargeable battery pack, α is the influencing factor of the battery replacement frequency at the battery replacement station, βN is the influencing factor of the life of the Nth rechargeable battery pack, γ is the influencing factor of the charging device occupied by the charging station, and η is the influencing factor of electricity price.

[0084] That is to say, the charging current of each rechargeable battery pack is the minimum value obtained by multiplying the charging reference current of the corresponding rechargeable battery pack and the charging reference current, the battery swap station and battery swap frequency influencing factor, the rechargeable battery pack life influencing factor, the charging station occupancy charging device influencing factor, and the electricity price influencing factor.

[0085] As a possible implementation, Figure 7 As shown in the figure, the influencing factors of the battery swapping frequency of the battery swapping station are obtained based on the historical battery swapping data and the benchmark battery swapping frequency, which may specifically include:

[0086] S701, estimate the battery replacement data for each second time period based on the battery replacement data in the past first time period.

[0087] S702, estimate the number of battery replacements in the future third time period based on the battery replacement data of each second time period and the number of battery replacements in the past third time period.

[0088] S703, obtaining the influencing factor of the battery swapping frequency of the battery swapping station according to the number of battery swapping in the third period in the future and the benchmark battery swapping frequency.

[0089] Among them, the first period, the second period and the third period can be selected according to actual conditions, and no specific restrictions are made in the embodiments of the present invention. For example, the first period is 30 days, the second period is 1 day, and the third period is 1 hour, that is, based on the battery replacement data of the past 30 days, the daily battery replacement data is counted, and the number of battery replacements in the next hour is calculated based on the number of battery replacements in the past hour.

[0090] As an example, the influencing factor of battery swap frequency at a battery swap station = the number of battery swaps in the third period in the future / the benchmark battery swap frequency; the influencing factor of charging devices = the total number of charging devices / (the total number of charging devices - the number of charging devices occupied by vehicles in the charging station).

[0091] That is to say, the influencing factor of the battery swap frequency in this example can be determined by the following formula:

[0092] α=CE_PreNum / CE_FreqNum,

[0093] Among them, α is the influencing factor of the battery replacement frequency at the battery replacement station, CE_PreNum is the number of battery replacements in the third period in the future, and CE_FreqNum is the benchmark battery replacement frequency.

[0094] The charging station occupancy charging device impact factor in this example can be determined by the following formula:

[0095] γ=N / (NM),

[0096] Among them, γ is the impact factor of charging station occupancy, N is the total number of charging devices, and M is the number of charging stations occupied. Figure 8 As shown, in some embodiments of the present invention, the control method of the charging and swapping station may also include:

[0097] S801, for charging devices that charge vehicles in a charging station, calculate the charging station revenue according to the real-time output voltage, real-time output current, charging time and first unit electricity revenue of each charging device.

[0098] It is understandable that for different times of the day, when the corresponding electricity prices are different, the corresponding service fees charged to customers per unit of electricity are also different, that is, the service fee per unit of electricity will be higher during peak time periods, and the service fee per unit of electricity will be lower during off-peak time periods. The per unit of electricity revenue obtained by deducting the electricity price of the corresponding time period from the service fee per unit of electricity in different time periods may also be different. And because the output power of the charging device can be selected according to actual needs, when calculating the charging station revenue, it is also necessary to determine the real-time output voltage and real-time output current of each charging device. Finally, according to the real-time output voltage, real-time output current, charging time and the first unit of electricity revenue of the charging device, the corresponding charging station revenue can be calculated.

[0099] As an example, the first unit of electricity revenue can be calculated by the following formula:

[0100] FCWave_Earn=FCWave_SerRates-Wave_Ele,

[0101] FCPeak_Earn=FCPeak_SerRates-Peak_Ele,

[0102] FCFlat_Earn=FCFlat_SerRates-Flat_Ele,

[0103] FCLow_Earn=FCLow_SerRates-Low_Ele;

[0105] Furthermore, after the first unit electricity revenue is determined, the revenue of the charging station in the corresponding time period can be calculated. As an example, the revenue of the charging station in each time period can be determined by the following formula:

[0106]

[0107]

[0111] Furthermore, after calculating the revenue of the charging station in each time period, the daily revenue of the charging station can be calculated by the following formula:

[0112] FC_Earn=FCWave_TolEarn+FCPeak_TolEarn+FCFlat_TolEarn+FCLow_TolEarn;

[0113] Among them, FC_Earn is the daily income of the charging station.

[0114] S802, for the charging devices that charge the rechargeable battery packs in the battery swap station, calculate the battery swap station revenue based on the real-time output voltage of each charging device, the charging current of the corresponding rechargeable battery pack, the charging time and the second unit electricity revenue.

[0115] As an example, the second unit electricity revenue can be calculated by the following formula:

[0116] CEWave_Earn=CE_SerRates-Wave_Ele;

[0117] CEPeak_Earn=CE_SerRates-Peak_Ele;

[0118] CEFlat_Earn=CE_SerRates-Flat_Ele;

[0121] Furthermore, after determining the revenue of the second unit of electricity, the revenue of the battery swap station in the corresponding time period can be calculated. As an example, the revenue of the battery swap station in each time period can be determined by the following formula:

[0122]

[0123]

[0127] After calculating the revenue of the battery swap station in each time period, the daily revenue of a single battery pack in the battery swap station can be calculated by the following formula: CE_EarnN=CEWave_TolEarn+CEPeak_TolEarn+CEFlat_TolEarn+CELow_TolEarn, where CE_EarnN is the daily revenue of the Nth battery pack.

[0128] Furthermore, after calculating the daily revenue of a single battery pack, the revenues of multiple battery packs included in the battery swap station are summed to obtain the daily revenue of the charging station in the embodiment of the present invention.

[0129] S903, calculating the sum of the revenue of the battery swap station and the revenue of the charging station to obtain the total revenue of the charging and battery swap station.

[0130] It is understandable that after calculating the revenue of the battery swap station and the charging station, the total revenue of the charging and swap station can be obtained by summing the revenue of the battery swap station and the revenue of the charging station. At the same time, because the embodiment of the present invention proposes to calculate the revenue of the battery swap station according to the charging current of the corresponding rechargeable battery pack, the charging current of the corresponding rechargeable battery pack is determined according to the influence factor of the frequency of battery swapping at the battery swap station, the influence factor of the charging device occupied by the charging station and the electricity price, as well as the charging reference current and life influence factor of each rechargeable battery pack. In other words, the determination of the charging current of the rechargeable battery pack comprehensively considers relevant factors such as the performance of the battery itself, the charging device and the electricity price during the time period, so that on the basis of ensuring the normal operation of the charging and swap station, the smallest possible charging current and the lowest possible charging cost are used, thereby reducing the charging cost of the battery pack, reducing the charging cost of the rechargeable battery pack, and maximizing the revenue of the charging and swap station.

[0131] According to the control method of the charging and swapping station of the embodiment of the present invention, the rechargeable battery pack and its charging position are determined according to the occupancy of the charging device by the vehicle in the charging station, the storage position of the fully charged battery pack and the storage position of the low-charged battery pack, and the rechargeable battery pack is charged according to the charging current of the rechargeable battery pack, so that the method can ensure the normal charging of each rechargeable battery pack on the basis of ensuring the reliable operation of the charging and swapping station, thereby achieving mutual coordination between the charging station and the swapping station. At the same time, when determining the charging current of the rechargeable battery pack, the charging current of each rechargeable battery pack is obtained according to the influencing factors of the swapping frequency of the battery swapping station, the influencing factors of the charging device occupied by the charging station and the electricity price, as well as the charging reference current and life influencing factors of each rechargeable battery pack, so that the determination of the charging current comprehensively considers the relevant factors such as the performance of the battery pack itself, the charging device and the electricity price during the time period, so that on the basis of ensuring the normal operation of the charging and swapping station, the charging cost of the rechargeable battery pack is reduced, the operating cost of the charging and swapping station is reduced, and the profit is maximized.
