[0056] Embodiments of the present disclosure 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 disclosure, and should not be construed as limiting the present disclosure.

[0057] With the rapid development of new energy vehicles, there are more and more charging and swapping stations for electric vehicles. Charging and swapping stations are energy stations that provide charging and quick replacement of power batteries for electric vehicles. In order to continue driving, electric vehicles require their electric energy to be replenished. For this reason, charging and swapping stations provide charging and swapping services for electric vehicles. However, as the number of charging and swapping services increases, the limited charging power makes the charging and swapping business more and more tense. Therefore, a reasonable charging and swapping strategy is needed to improve the power utilization of swapping stations.

[0058] In view of the above situation, the present disclosure provides a charging and battery swapping method for a battery swapping station. Figure 1 FIG. 1 is a flow chart of a charging and battery swapping method of a battery swapping station according to an exemplary embodiment. Figure 1As shown, the charging and swapping method of the battery swapping station is applied to the battery swapping station having multiple battery racks, each battery rack having multiple charging positions, and one charging position charges one battery, and the method includes:

[0059] Obtain the battery replacement status of the current vehicle to be replaced, the total output power of the charging position of each battery rack, and the current SOC status of each rechargeable battery on the battery rack;

[0060] Determine the required charging power of each rechargeable battery on the battery rack based on the charging power change curve corresponding to the battery SOC state and the current SOC state of each rechargeable battery on the battery rack;

[0061] According to the battery replacement status of the current vehicle to be replaced, the total output power of the charging slots of each battery rack and the required charging power of each rechargeable battery on the battery rack, the actual charging power of each charging slot on the battery rack to the rechargeable battery is adjusted.

[0062] In this exemplary embodiment, Figure 2 FIG. 1 is a schematic diagram of a charging and battery swapping system structure of a battery swapping station according to an exemplary embodiment. Figure 2 As shown, the charging and swapping system of the battery swap station includes multiple chargers, charger 1, charger 2... charger n, etc. One charger corresponds to multiple charging modules, 1M1, 1M2... 1Ma, and multiple charging positions, and one charging position can charge a battery pack, such as pack 11, pack 12... pack 1m. Figure 3 FIG. 1 is a schematic diagram of a charging power change curve corresponding to the battery SOC state of a battery swap station according to an exemplary embodiment. Figure 3 The charging power change curve corresponding to the battery SOC state shown in the figure shows that the required charging power is different when the battery has different SOC values. The required charging power is the reasonable charging power required to charge the battery when the battery SOC value changes.

[0063] In this exemplary embodiment, the total output power of the charging positions of each battery rack may be the total output power of the charging positions of each battery rack, or may be the total output power of multiple battery racks.

[0064] According to the charging and swapping method of the battery swapping station of the embodiment of the present disclosure, the battery swapping station has multiple battery racks, each battery rack has multiple charging positions, and one charging position charges one battery. The method includes: obtaining the battery swapping status of the current vehicle to be swapped, the total power output of the charging positions of each battery rack, and the current SOC status of each rechargeable battery on the battery rack; determining the required charging power of each rechargeable battery on the battery rack based on the charging power change curve corresponding to the battery SOC status and the current SOC status of each rechargeable battery on the battery rack; adjusting the actual charging power of each charging position on the battery rack to the rechargeable battery according to the battery swapping status of the current vehicle to be swapped, the total power output of the charging positions of each battery rack, and the required charging power of each rechargeable battery on the battery rack. In the present application, in order to improve the power utilization rate of the total power output of the battery swapping station, when charging the battery, the actual charging power of each charging position on the battery rack to the rechargeable battery is adjusted based on the total power output of the charging positions of each battery rack and the required charging power of each rechargeable battery on the battery rack in combination with the battery swapping status of the current vehicle to be swapped. This will help improve the power utilization rate of the total power output of the battery swap station, and thus help improve the quality of charging and battery swapping services at the battery swap station.

[0065] In some embodiments, the battery replacement status of the vehicle currently to be replaced includes: the number of batteries to be replaced for the vehicle currently to be replaced;

[0066] The method of adjusting the actual charging power of each charging position on the battery rack to the rechargeable battery according to the battery replacement state of the current vehicle to be replaced, the total output power of the charging position of each battery rack, and the required charging power of each rechargeable battery on the battery rack includes:

[0067] If the number of batteries to be replaced in the current vehicle to be replaced is less than the number of fully charged batteries on the battery rack, then the actual charging power of each charging position on the battery rack is adjusted based on the total output power of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose placement time is less than the first threshold, or the actual charging power of each charging position on the battery rack is adjusted based on the total output power of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose SOC value is less than the second threshold;

[0068] If the number of batteries to be replaced in the current vehicle is greater than or equal to the number of fully charged batteries on the battery rack, the actual charging power of each charging slot on the battery rack is adjusted based on the total power output of the charging slots of each battery rack to prioritize the required charging power of rechargeable batteries with an SOC value greater than a second threshold. Or, the actual charging power of each charging slot on the battery rack is adjusted based on the total power output of the charging slots of each battery rack to prioritize the required charging power of rechargeable batteries with a placement time greater than a first threshold.

[0069] In this exemplary embodiment, when the number of batteries to be replaced by the current vehicle is less than the number of fully charged batteries on the battery rack, it means that the rechargeable batteries available for replacement on the battery rack meet the current battery replacement needs of the vehicle. At this time, the total power output of the charging position of each battery rack can be prioritized to meet the required charging power of the rechargeable batteries whose placement time is less than the first threshold. For example, the battery that is newly connected to the charging position is appropriately charged with a higher power.

[0070] Wherein, if the number of batteries to be replaced by the current vehicle to be replaced is less than the number of batteries in a fully charged state on the battery rack, the battery replacement vehicle is replaced, and the method includes:

[0071] When replacing batteries in a battery-swapping vehicle, the battery that first enters the charging compartment among the fully charged batteries is selected as the replacement battery according to the first-in-first-out principle.

[0072] For example, according to the battery placement time and battery rack serial number in the station, batteries are taken from each battery rack for replacement in rotation. The time for each replacement is T1, so that the charging time of the battery pack on each battery rack is staggered by about T1*n time from the charging time of the last replacement battery pack; n is greater than or equal to 1.

[0073] In this exemplary embodiment, the number of batteries to be replaced by the current vehicle to be replaced is greater than or equal to the number of fully charged batteries on the battery rack, indicating that the rechargeable batteries available for replacement on the battery rack cannot meet the current battery replacement needs of the vehicle. At this time, the total power output of the charging position of each battery rack can be prioritized to meet the required charging power of the rechargeable batteries with an SOC value greater than the second threshold. Among them, the total power output of the charging position of each battery rack can be prioritized to meet the required charging power of the rechargeable batteries with an SOC value greater than the second threshold, including:

[0074] The total output power of the charging position of each battery rack can be prioritized to meet the required charging power of the rechargeable batteries whose remaining charging time is less than the third threshold. Among them, the larger the battery SOC value, the shorter the remaining charging time. Among them, the first threshold, the second threshold, and the third threshold can all be set by yourself. In this way, through the above-mentioned actual charging power adjustment, it is beneficial to improve the power utilization rate of the total output power of the battery swap station and the battery swap service capacity of the battery swap station.

[0075] In some embodiments, the actual charging power of each charging position on each battery rack is adjusted based on the total power output of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose placement time is less than the first threshold, including:

[0076] Determine the number of charging modules of each battery rack based on the total power output of the charging positions of each battery rack;

[0077] Based on the total power output of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose placement time is less than the first threshold, the number of charging modules for charging the rechargeable batteries in each charging position on each battery rack is adjusted;

[0078] The actual charging power of each charging position on each battery rack is adjusted based on the total power output of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable battery whose SOC value is less than the second threshold, including:

[0079] Determine the number of charging modules of each battery rack based on the total power output of the charging positions of each battery rack;

[0080] Based on the total power output of the charging positions of each battery rack giving priority to meeting the required charging power of the rechargeable batteries whose SOC values ​​are less than the second threshold, the number of charging modules for charging the rechargeable batteries in each charging position on each battery rack is adjusted.

[0081] In this exemplary embodiment, when multiple battery packs form a small ring network, the total charging power P of the ring network is the total power output of the charging position of each battery rack. The power of a charging module is P2, and the number of charging modules of the battery rack is P / P2.

[0082] When adjusting the actual charging power of each charging slot on the battery rack for the rechargeable batteries based on the total output power of the charging slot of each battery rack giving priority to meeting the required charging power of rechargeable batteries with a short placement time, the number of charging modules used to charge the rechargeable batteries in each charging slot on the battery rack can be adjusted based on the total output power of the charging slot of each battery rack giving priority to meeting the required charging power of rechargeable batteries with a placement time lower than a first threshold.

[0083] In some embodiments, the total power output of the charging positions of each battery rack prioritizes the required charging power of the rechargeable batteries whose placement time is less than the first threshold, so as to adjust the number of charging modules for charging the rechargeable batteries in each charging position on each battery rack, including:

[0084] Obtaining the placement time of each rechargeable battery on the battery rack;

[0085] Based on the placement time of each rechargeable battery on the battery rack, determining a first rechargeable battery on the battery rack whose placement time is lower than a first threshold and a second rechargeable battery whose placement time is higher than or equal to the first threshold;

[0086] The number of charging modules used to charge the rechargeable battery in each charging position on each battery rack is adjusted by reducing the number of charging modules used to charge the second rechargeable battery and increasing the number of charging modules used to charge the first rechargeable battery.

[0087] In this exemplary embodiment, the number of charging modules for charging the rechargeable battery in each charging position on each battery rack is adjusted by reducing the number of charging modules for charging the second rechargeable battery and increasing the number of charging modules for charging the first rechargeable battery, including:

[0088] Based on the required charging power of each rechargeable battery on the battery rack and the power P2 of a charging module, determine the number of charging modules required to charge each rechargeable battery;

[0089] When the number of charging modules of the battery rack is less than the total number of charging modules required for charging each rechargeable battery, the number of charging modules for charging the second rechargeable battery is reduced, and the number of charging modules for charging the first rechargeable battery is increased, thereby improving the charging and swapping service quality of the battery swapping station.

[0090] The method of adjusting the number of charging modules for charging the rechargeable batteries in each charging position on each battery rack based on the total power output of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose SOC value is less than the second threshold, includes:

[0091] Obtaining the SOC value of each rechargeable battery on the battery rack;

[0092] Based on the SOC values ​​of the rechargeable batteries on the battery rack, determining a third rechargeable battery on the battery rack having an SOC value greater than a second threshold and a fourth rechargeable battery on the battery rack having an SOC value less than the second threshold;

[0093] The number of charging modules for charging the rechargeable battery in each charging position on each battery rack is adjusted by increasing the number of charging modules for charging the fourth rechargeable battery and reducing the number of charging modules for charging the third rechargeable battery.

[0094] In some embodiments, the actual charging power of each charging position on each battery rack is adjusted based on the total power output of the charging position of each battery rack giving priority to satisfying the required charging power of the rechargeable battery whose SOC value is greater than the second threshold, including:

[0095] Determine the number of charging modules of each battery rack based on the total power output of the charging positions of each battery rack;

[0096] Based on the total power output of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose SOC values ​​are greater than the second threshold, the number of charging modules for charging the rechargeable batteries in each charging position on each battery rack is adjusted;

[0097] The actual charging power of each charging position on each battery rack is adjusted based on the total output power of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose placement time is longer than the first threshold, including:

[0098] Determine the number of charging modules of each battery rack based on the total power output of the charging positions of each battery rack;

[0099] Based on the total power output of the charging positions of each battery rack giving priority to meeting the required charging power of rechargeable batteries whose placement time is longer than a first threshold, the number of charging modules for charging the rechargeable batteries in each charging position on each battery rack is adjusted.

[0100] In this exemplary embodiment, when multiple battery packs form a small ring network, the total charging power P of the ring network is the total power output of the charging position of each battery rack. The power of a charging module is P2, and the number of charging modules of the battery rack is P / P2.

[0101] When adjusting the actual charging power of each charging slot on the battery rack for the rechargeable batteries based on the fact that the total output power of the charging slot of each battery rack prioritizes meeting the required charging power of the rechargeable batteries whose SOC value is greater than the second threshold, the number of charging modules used to charge the rechargeable batteries in each charging slot on the battery rack can be adjusted based on the fact that the total output power of the charging slot of each battery rack prioritizes meeting the required charging power of the rechargeable batteries whose SOC value is greater than the second threshold.

[0102] The method of adjusting the number of charging modules for charging the rechargeable batteries in each charging position on each battery rack based on the total power output of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose placement time is longer than the first threshold, includes:

[0103] Obtaining the placement time of each rechargeable battery on the battery rack;

[0104] Based on the placement time of each rechargeable battery on the battery rack, determining a first rechargeable battery on the battery rack whose placement time is lower than a first threshold and a second rechargeable battery whose placement time is higher than the first threshold;

[0105] The number of charging modules used to charge the rechargeable battery in each charging position on each battery rack is adjusted by reducing the number of charging modules used to charge the first rechargeable battery and increasing the number of charging modules used to charge the second rechargeable battery.

[0106] In some embodiments, the total power output of the charging positions of each battery rack to give priority to meeting the required charging power of the rechargeable battery whose SOC value is greater than the second threshold value, to adjust the number of charging modules for charging the rechargeable battery in each charging position on each battery rack, includes:

[0107] Obtaining the SOC value of each rechargeable battery on the battery rack;

[0108] Based on the SOC values ​​of the rechargeable batteries on the battery rack, determining a third rechargeable battery on the battery rack having an SOC value greater than a second threshold and a fourth rechargeable battery on the battery rack having an SOC value less than or equal to the second threshold;

[0109] The number of charging modules for charging the rechargeable battery in each charging position on each battery rack is adjusted by increasing the number of charging modules for charging the third rechargeable battery and reducing the number of charging modules for charging the fourth rechargeable battery.

[0110] In this exemplary embodiment, the number of charging modules for charging the rechargeable battery in each charging position on each battery rack is adjusted by increasing the number of charging modules for charging the third rechargeable battery and reducing the number of charging modules for charging the fourth rechargeable battery, including:

[0111] Based on the required charging power of each rechargeable battery on the battery rack and the power P2 of a charging module, determine the number of charging modules required to charge each rechargeable battery;

[0112] When the number of charging modules of the battery rack is less than the total number of charging modules required for charging each rechargeable battery, the number of charging modules for charging the third rechargeable battery is increased, and the number of charging modules for charging the fourth rechargeable battery is reduced to adjust the number of charging modules for charging the rechargeable battery in each charging position on each battery rack, thereby improving the charging and battery swapping service quality of the battery swapping station.

[0113] In the above embodiments, when the number of charging modules of the battery rack is greater than the total number of charging modules required for charging each rechargeable battery, it means that the charging modules of the battery rack are sufficient. At this time, the charging modules can be allocated according to the number of charging modules required for charging each rechargeable battery.

[0114] In some embodiments, the number of batteries to be replaced for the vehicle currently to be replaced includes:

[0115] The sum of the number of vehicles that have made reservations for battery swaps at the current battery swap station and the number of vehicles that are currently queuing for battery swaps at the station.

[0116] In this exemplary embodiment, when determining the number of batteries to be replaced by the current battery replacement vehicle, two parts are included: one is the number of batteries to be replaced by the vehicles that have made reservations and queued for battery replacement at the current battery replacement station, and the other is the number of batteries to be replaced by the vehicles that are currently queuing for battery replacement at the station.

[0164] The present disclosure provides a charging and battery swapping device for a battery swapping station. Figure 7 FIG. 1 is a schematic diagram of a charging and battery swapping device of a battery swapping station according to an exemplary embodiment. Figure 7 As shown, the charging and swapping device of the battery swapping station, the applied battery swapping station has multiple battery racks, each battery rack has multiple charging positions, and one charging position charges one battery, and the device includes:

[0165] The data acquisition module 30 is used to obtain the battery replacement status of the current vehicle to be replaced, the total output power of the charging position of each battery rack, and the current SOC status of each rechargeable battery on the battery rack;

[0166] The power determination module 31 is used to determine the required charging power of each rechargeable battery on the battery rack based on the charging power change curve corresponding to the battery SOC state and the current SOC state of each rechargeable battery on the battery rack;

[0167] The power adjustment module 32 is used to adjust the actual charging power of each charging position on the battery rack to the rechargeable battery according to the battery replacement status of the current vehicle to be replaced, the total output power of the charging position of each battery rack and the required charging power of each rechargeable battery on the battery rack.

[0168] In this exemplary embodiment, Figure 2As shown in the figure, the charging and swapping system of the battery swap station includes multiple chargers. One charger corresponds to multiple charging modules and multiple charging positions, and one charging position can charge one battery pack. Figure 3 The charging power change curve corresponding to the battery SOC state shown in the figure shows that the required charging power is different when the battery has different SOC values. The required charging power is the reasonable charging power required to charge the battery when the battery SOC value changes.

[0169] In this exemplary embodiment, the total output power of the charging positions of each battery rack may be the total output power of the charging positions of each battery rack, or may be the total output power of multiple battery racks.

[0170] According to the charging and swapping device of the battery swapping station of the embodiment of the present disclosure, the battery swapping station used has multiple battery racks, each battery rack has multiple charging positions, and one charging position charges one battery. Among them, the charging and swapping device is used to: obtain the battery swapping status of the current vehicle to be swapped, the total power output of the charging position of each battery rack, and the current SOC state of each rechargeable battery on the battery rack; determine the required charging power of each rechargeable battery on the battery rack based on the charging power change curve corresponding to the battery SOC state, and the current SOC state of each rechargeable battery on the battery rack; according to the battery swapping status of the current vehicle to be swapped, the total power output of the charging position of each battery rack, and the required charging power of each rechargeable battery on the battery rack, adjust the actual charging power of each charging position on the battery rack to the rechargeable battery. In this application, in order to improve the power utilization rate of the total power output of the battery swapping station, when charging the battery, combined with the battery swapping status of the current vehicle to be swapped, based on the total power output of the charging position of each battery rack and the required charging power of each rechargeable battery on the battery rack, the actual charging power of each charging position on the battery rack to the rechargeable battery is adjusted. This will help improve the power utilization rate of the total power output of the battery swap station, and thus help improve the quality of charging and battery swapping services at the battery swap station.

[0171] In some embodiments, the battery replacement status of the vehicle currently to be replaced includes: the number of batteries to be replaced for the vehicle currently to be replaced;

[0172] The power adjustment module is used to

[0173] If the number of batteries to be replaced in the current vehicle to be replaced is less than the number of fully charged batteries on the battery rack, then the actual charging power of each charging position on the battery rack is adjusted based on the total output power of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose placement time is less than the first threshold, or the actual charging power of each charging position on the battery rack is adjusted based on the total output power of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose SOC value is less than the second threshold;

[0174] If the number of batteries to be replaced in the current vehicle is greater than or equal to the number of fully charged batteries on the battery rack, the actual charging power of each charging slot on the battery rack is adjusted based on the total power output of the charging slots of each battery rack to prioritize the required charging power of rechargeable batteries with an SOC value greater than a second threshold. Or, the actual charging power of each charging slot on the battery rack is adjusted based on the total power output of the charging slots of each battery rack to prioritize the required charging power of rechargeable batteries with a placement time greater than a first threshold.

[0175] In this exemplary embodiment, when the number of batteries to be replaced by the current vehicle is less than the number of fully charged batteries on the battery rack, it means that the rechargeable batteries available for replacement on the battery rack meet the current battery replacement needs of the vehicle. At this time, the total power output of the charging position of each battery rack can be prioritized to meet the required charging power of the rechargeable batteries whose placement time is less than the first threshold. For example, the battery that is newly connected to the charging position is appropriately charged with a higher power.

[0176] Wherein, if the number of batteries to be replaced by the current vehicle to be replaced is less than the number of batteries in a fully charged state on the battery rack, the battery replacement vehicle is replaced, and the method includes:

[0177] When replacing batteries in a battery-swapping vehicle, the battery that first enters the charging compartment among the fully charged batteries is selected as the replacement battery according to the first-in-first-out principle.

[0178] For example, according to the battery placement time and battery rack serial number in the station, batteries are taken from each battery rack for replacement in rotation. The time for each replacement is T1, so that the charging time of the battery pack on each battery rack is staggered by about T1*n time from the charging time of the last replacement battery pack; n is greater than or equal to 1.

[0179] In this exemplary embodiment, the number of batteries to be replaced by the current vehicle to be replaced is greater than or equal to the number of fully charged batteries on the battery rack, indicating that the rechargeable batteries available for replacement on the battery rack cannot meet the current battery replacement needs of the vehicle. At this time, the total power output of the charging position of each battery rack can be prioritized to meet the required charging power of the rechargeable batteries with an SOC value greater than the second threshold. Among them, the total power output of the charging position of each battery rack can be prioritized to meet the required charging power of the rechargeable batteries with an SOC value greater than the second threshold, including:

[0180] The total output power of the charging position of each battery rack can be prioritized to meet the required charging power of the rechargeable batteries whose remaining charging time is less than the third threshold. Among them, the larger the battery SOC value, the shorter the remaining charging time. Among them, the first threshold, the second threshold, and the third threshold can all be set by yourself. In this way, through the above-mentioned actual charging power adjustment, it is beneficial to improve the power utilization rate of the total output power of the battery swap station and the battery swap service capacity of the battery swap station.

[0181] In some embodiments, the power adjustment module is used to

[0182] Determine the number of charging modules of each battery rack based on the total power output of the charging positions of each battery rack;

[0183] Based on the total power output of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose placement time is less than the first threshold, the number of charging modules for charging the rechargeable batteries in each charging position on each battery rack is adjusted; or,

[0184] Determine the number of charging modules of each battery rack based on the total power output of the charging positions of each battery rack;

[0185] Based on the total power output of the charging positions of each battery rack giving priority to meeting the required charging power of the rechargeable batteries whose SOC values ​​are less than the second threshold, the number of charging modules for charging the rechargeable batteries in each charging position on each battery rack is adjusted.

[0186] In this exemplary embodiment, when multiple battery packs form a small ring network, the total charging power P of the ring network is the total power output of the charging position of each battery rack. The power of a charging module is P2, and the number of charging modules of the battery rack is P / P2.

[0187] When adjusting the actual charging power of each charging slot on the battery rack for the rechargeable batteries based on the total output power of the charging slot of each battery rack giving priority to meeting the required charging power of rechargeable batteries with a short placement time, the number of charging modules used to charge the rechargeable batteries in each charging slot on the battery rack can be adjusted based on the total output power of the charging slot of each battery rack giving priority to meeting the required charging power of rechargeable batteries with a placement time lower than a first threshold.

[0188] In some embodiments, the power adjustment module is used to

[0189] Obtaining the placement time of each rechargeable battery on the battery rack;

[0190] Based on the placement time of each rechargeable battery on the battery rack, determining a first rechargeable battery on the battery rack whose placement time is lower than a first threshold and a second rechargeable battery whose placement time is higher than or equal to the first threshold;

[0191] The number of charging modules used to charge the rechargeable battery in each charging position on each battery rack is adjusted by reducing the number of charging modules used to charge the second rechargeable battery and increasing the number of charging modules used to charge the first rechargeable battery.

[0192] In this exemplary embodiment, the number of charging modules for charging the rechargeable battery in each charging position on each battery rack is adjusted by reducing the number of charging modules for charging the second rechargeable battery and increasing the number of charging modules for charging the first rechargeable battery, including:

[0193] Based on the required charging power of each rechargeable battery on the battery rack and the power P2 of a charging module, determine the number of charging modules required to charge each rechargeable battery;

[0194] When the number of charging modules of the battery rack is less than the total number of charging modules required for charging each rechargeable battery, the number of charging modules for charging the second rechargeable battery is reduced, and the number of charging modules for charging the first rechargeable battery is increased, thereby improving the charging and swapping service quality of the battery swapping station.

[0195] In some embodiments, the power adjustment module is used to

[0196] Determine the number of charging modules of each battery rack based on the total power output of the charging positions of each battery rack;

[0197] Based on the total power output of the charging positions of each battery rack giving priority to satisfying the required charging power of the rechargeable batteries whose SOC value is greater than the second threshold, the number of charging modules for charging the rechargeable batteries in each charging position on each battery rack is adjusted; or,

[0198] Determine the number of charging modules of each battery rack based on the total power output of the charging positions of each battery rack;

[0199] Based on the total power output of the charging positions of each battery rack giving priority to meeting the required charging power of rechargeable batteries whose placement time is longer than a first threshold, the number of charging modules for charging the rechargeable batteries in each charging position on each battery rack is adjusted.

[0200] In this exemplary embodiment, when multiple battery packs form a small ring network, the total charging power P of the ring network is the total power output of the charging position of each battery rack. The power of a charging module is P2, and the number of charging modules of the battery rack is P / P2.

[0201] When adjusting the actual charging power of each charging slot on the battery rack for the rechargeable batteries based on the fact that the total output power of the charging slot of each battery rack prioritizes meeting the required charging power of the rechargeable batteries whose SOC value is greater than the second threshold, the number of charging modules used to charge the rechargeable batteries in each charging slot on the battery rack can be adjusted based on the fact that the total output power of the charging slot of each battery rack prioritizes meeting the required charging power of the rechargeable batteries whose SOC value is greater than the second threshold.

[0202] In some embodiments, the power adjustment module is used to

[0203] Obtaining the SOC value of each rechargeable battery on the battery rack;

[0204] Based on the SOC values ​​of the rechargeable batteries on the battery rack, determining a third rechargeable battery on the battery rack having an SOC value greater than a second threshold and a fourth rechargeable battery on the battery rack having an SOC value less than or equal to the second threshold;

[0205] The number of charging modules for charging the rechargeable battery in each charging position on each battery rack is adjusted by increasing the number of charging modules for charging the third rechargeable battery and reducing the number of charging modules for charging the fourth rechargeable battery.

[0206] In this exemplary embodiment, the number of charging modules for charging the rechargeable battery in each charging position on each battery rack is adjusted by increasing the number of charging modules for charging the third rechargeable battery and reducing the number of charging modules for charging the fourth rechargeable battery, including:

[0207] Based on the required charging power of each rechargeable battery on the battery rack and the power P2 of a charging module, determine the number of charging modules required to charge each rechargeable battery;

[0208] When the number of charging modules of the battery rack is less than the total number of charging modules required for charging each rechargeable battery, the number of charging modules for charging the third rechargeable battery is increased, and the number of charging modules for charging the fourth rechargeable battery is reduced to adjust the number of charging modules for charging the rechargeable battery in each charging position on each battery rack, thereby improving the charging and battery swapping service quality of the battery swapping station.

[0209] In the above embodiments, when the number of charging modules of the battery rack is greater than the total number of charging modules required for charging each rechargeable battery, it means that the charging modules of the battery rack are sufficient. At this time, the charging modules can be allocated according to the number of charging modules required for charging each rechargeable battery.

[0210] In some embodiments, the number of batteries to be replaced for the vehicle currently to be replaced includes:

[0211] The sum of the number of vehicles that have made reservations for battery swaps at the current battery swap station and the number of vehicles that are currently queuing for battery swaps at the station.

[0212] In this exemplary embodiment, when determining the number of batteries to be replaced by the current battery replacement vehicle, two parts are included: one is the number of batteries to be replaced by the vehicles that have made reservations and queued for battery replacement at the current battery replacement station, and the other is the number of batteries to be replaced by the vehicles that are currently queuing for battery replacement at the station. The sum of the two parts is used as the number of batteries to be replaced by the current battery replacement vehicle, which is conducive to a more comprehensive estimation of the number of batteries to be replaced by the battery replacement vehicle, thereby providing more accurate and reasonable data support for improving the battery replacement service capabilities of the battery replacement station.

[0213] In some embodiments, obtaining the current SOC state of each rechargeable battery on the battery rack includes:

[0214] Obtain the current SOC status of the battery to be replaced and the current SOC status of the rechargeable battery on the battery rack that is being charged; wherein the battery to be replaced is the battery replaced by the vehicle to be replaced.

[0215] In this exemplary embodiment, the current SOC state of each rechargeable battery on the battery rack includes obtaining the current SOC state of the battery to be replaced and the current SOC state of the rechargeable battery on the battery rack that is being charged. That is, each rechargeable battery on the battery rack includes the battery on the original battery rack and the battery replaced by the battery swap vehicle and about to enter the charging position.

[0216] In some embodiments, the apparatus includes: a charging module;

[0217] Before obtaining the current SOC state of each rechargeable battery on the battery rack, the charging module is used to

[0218] Determine the charging position of the battery to be replaced according to the battery occupancy status of each charging position on the battery rack;

[0219] Place the battery to be replaced in the charging compartment for charging.

[0220] In this exemplary embodiment, when placing the battery replaced by the battery swapping vehicle into the charging position, the charging position of the battery to be replaced can be determined according to the battery occupancy status of each charging position on the battery rack. For example, the charging positions of the battery rack are numbered and placed in sequence according to the numbering order.
