[0056] Embodiments of this disclosure are described in detail below, examples of which are illustrated in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this disclosure, and should not be construed as limiting this disclosure.

[0057] With the rapid development of new energy vehicles, the number of electric vehicle charging and battery swapping stations is also increasing. These stations provide charging and rapid battery swapping services for electric vehicles. Electric vehicles require continuous power replenishment for continuous operation. Therefore, charging and battery swapping stations provide charging and swapping services. However, as the demand for charging and swapping services grows, limited charging capacity is causing increasing strain on these services. Therefore, a reasonable charging and swapping strategy is needed to improve the power utilization rate of battery swapping stations.

[0058] In view of the above situation, this disclosure provides a charging and swapping method for a battery swapping station. Figure 1 This is a flowchart illustrating a charging and swapping method for a battery swapping station according to an exemplary embodiment. Figure 1As shown, the charging and swapping method of this battery swapping station applies to a battery swapping station having multiple battery racks, each battery rack having multiple charging slots, with one charging slot charging one battery. The method includes:

[0059] The battery swapping status of the vehicle currently waiting to be swapped, the total output power of the charging compartment of each battery rack, and the current SOC status of each charging battery on the battery rack are obtained.

[0060] 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, the required charging power of each rechargeable battery on the battery rack is determined.

[0061] Based on the current battery swapping status of the vehicle, the total output power of the charging compartments of each battery rack, and the required charging power of each battery on the battery rack, the actual charging power of each charging compartment on the battery rack is adjusted.

[0062] In this exemplary embodiment, Figure 2 This is a schematic diagram illustrating the charging and swapping system structure of a battery swapping station according to an exemplary embodiment. Figure 2 As shown, the battery swapping station's charging and swapping system includes multiple chargers, such as charger 1, charger 2, ..., charger n. Each charger corresponds to multiple charging modules, such as 1M1, 1M2, ..., 1Ma, and multiple charging compartments. Each charging compartment can charge one battery pack, such as pack 11, pack 12, ..., pack 1m. Figure 3 This is a schematic diagram illustrating the charging power variation curve corresponding to the battery's state of charge (SOC) at a battery swapping station, according to an exemplary embodiment. For example... Figure 3 The curves showing the charging power changes corresponding to different battery SOC values ​​indicate that the required charging power varies with each SOC value. The required charging power is the appropriate charging power needed to charge the battery as its SOC value changes.

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

[0064] According to the battery swapping station charging and swapping method of the present disclosure, the battery swapping station has multiple battery racks, each battery rack has multiple charging slots, and one charging slot charges one battery. The method includes: acquiring the current battery swapping status of the vehicle to be swapped, the total output power of the charging slots of each battery rack, and the current SOC status of each charging battery on the battery rack; determining the required charging power of each charging 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 charging battery on the battery rack; and adjusting the actual charging power of each charging slot on the battery rack to the charging battery based on the current battery swapping status of the vehicle to be swapped, the total output power of the charging slots of each battery rack, and the required charging power of each charging battery on the battery rack. In this application, in order to improve the power utilization rate of the total output power of the battery swapping station, when charging the battery, the actual charging power of each charging slot on the battery rack to the charging battery is adjusted based on the current battery swapping status of the vehicle to be swapped, the total output power of the charging slots of each battery rack, and the required charging power of each charging battery on the battery rack. This helps to improve the power utilization rate of the total output power of the battery swapping station, and thus improves the quality of the charging and swapping services provided by the station.

[0065] In some embodiments, the battery swapping status of the current battery swapping vehicle includes: the number of batteries swapped for the current battery swapping vehicle;

[0066] The step of adjusting the actual charging power of each charging compartment on the battery rack to the rechargeable battery based on the current battery swapping status of the vehicle, the total output power of each charging compartment of the battery rack, and the required charging power of each rechargeable battery on the battery rack includes:

[0067] If the number of batteries to be swapped for the current vehicle is less than the number of batteries in the battery rack that are fully charged, then the actual charging power of each charging compartment on each battery rack is adjusted based on the total output power of the charging compartment of each battery rack prioritizing the charging power required by the batteries that have been placed for a period of less than a first threshold. Alternatively, the actual charging power of each charging compartment on each battery rack is adjusted based on the total output power of the charging compartment of each battery rack prioritizing the charging power required by the batteries that have a SOC value less than a second threshold.

[0068] If the number of batteries to be swapped for a vehicle is greater than or equal to the number of batteries in the battery rack that are fully charged, then the actual charging power of each charging compartment on each battery rack is adjusted based on the total output power of the charging compartment of each battery rack prioritizing the charging power required by batteries with a SOC value greater than a second threshold. Alternatively, the actual charging power of each charging compartment on each battery rack is adjusted based on the total output power of the charging compartment of each battery rack prioritizing the charging power required by batteries that have been placed for a longer period than a first threshold.

[0069] In this exemplary embodiment, when the number of batteries to be swapped for the current vehicle is less than the number of fully charged batteries on the battery rack, it indicates that the available rechargeable batteries on the battery rack meet the current battery swapping needs of the vehicle. In this case, the total output power of each charging bay in the battery rack can be prioritized to meet the charging power requirements of batteries that have been placed for less than a first threshold. For example, the batteries that are most recently connected to the charging bay can be charged with a higher power.

[0070] Wherein, if the number of batteries to be swapped for a vehicle is less than the number of fully charged batteries on the battery rack, the vehicle is swapped, and the method includes:

[0071] When swapping batteries in a battery-swapping vehicle, the first-in, first-out principle is followed. The battery that enters the charging compartment first among the fully charged batteries is selected as the battery for swapping.

[0072] For example, based on the battery placement time and battery rack number within the station, batteries are taken from each battery rack in rotation for battery swapping. Each battery swap takes T1 hours, ensuring that the charging time of the battery pack being swapped this time is staggered from the charging time of the battery pack being swapped last time by approximately T1*n time, where n is greater than or equal to 1.

[0073] In this exemplary embodiment, if the number of batteries to be swapped in the current battery-swapping vehicle is greater than or equal to the number of batteries in the battery rack that are fully charged, it indicates that the available rechargeable batteries in the battery rack cannot meet the current battery-swapping needs of the vehicle. In this case, the total output power of each battery rack's charging compartment can be prioritized to meet the charging power requirements of batteries with a State of Charge (SOC) value greater than a second threshold. This priority includes:

[0074] The total output power of each battery rack's charging compartments can be prioritized to meet the charging power needs of batteries with remaining charging time less than a third threshold. A higher battery SOC value indicates a shorter remaining charging time. The first, second, and third thresholds can all be set manually. This adjustment of actual charging power improves the power utilization rate of the battery swapping station's total output power and enhances its battery swapping service capabilities.

[0075] In some embodiments, adjusting the actual charging power of each charging compartment on each battery rack to the charging battery based on the total output power of each charging compartment of the battery rack prioritizing the charging power required by the charging battery whose placement time is less than a first threshold includes:

[0076] The number of charging modules in each battery rack is determined based on the total output power of the charging compartments in each battery rack.

[0077] Based on the total output power of the charging compartments of each battery rack, the charging power required to charge batteries with a placement time of less than a first threshold is prioritized to be met, thereby adjusting the number of charging modules in each charging compartment of each battery rack to charge the batteries.

[0078] The adjustment of the actual charging power of each charging compartment on each battery rack, based on the total output power of each charging compartment prioritizing the charging power required by batteries with a SOC value less than a second threshold, includes:

[0079] The number of charging modules in each battery rack is determined based on the total output power of the charging compartments in each battery rack.

[0080] The number of charging modules in each charging compartment of each battery rack is adjusted to prioritize charging power for batteries with a SOC value less than a second threshold, based on the total output power of each charging compartment.

[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 output power of the charging compartments of each battery rack. The power of one charging module is P2, and the number of charging modules in the battery rack is P / P2.

[0082] When adjusting the actual charging power of each charging compartment on the battery rack to charge batteries based on the principle that the total output power of each charging compartment of the battery rack should prioritize the charging power required by batteries that have been placed for a short period of time, the number of charging modules in each charging compartment of the battery rack can be adjusted to charge batteries based on the principle that the total output power of each charging compartment of the battery rack should prioritize the charging power required by batteries that have been placed for a short period of time less than a first threshold.

[0083] In some embodiments, adjusting the number of charging modules in each charging slot of each battery rack to charge the batteries based on the total output power of the charging compartments of each battery rack prioritizing the charging power required by the batteries that have been placed for a duration less than a first threshold includes:

[0084] Obtain 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, the first rechargeable battery with a placement time lower than a first threshold and the second rechargeable battery with a placement time higher than or equal to the first threshold are determined.

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

[0087] In this exemplary embodiment, adjusting the number of charging modules charging the rechargeable battery in each charging compartment of each battery rack by reducing the number of charging modules charging the second rechargeable battery and increasing the number of charging modules charging the first rechargeable battery includes:

[0088] Based on the required charging power of each rechargeable battery in 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 in the battery rack is less than the total number of charging modules required to charge each battery, the number of charging modules charging the second battery is reduced, and the number of charging modules charging the first battery is increased, thereby improving the charging and swapping service quality of the battery swapping station.

[0090] The method of prioritizing the charging power demand of batteries with a SOC value less than a second threshold by adjusting the total output power of each charging compartment on each battery rack to charge the batteries includes:

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

[0092] Based on the SOC value of each rechargeable battery on the battery rack, a third rechargeable battery with an SOC value greater than the second threshold and a fourth rechargeable battery with an SOC value less than the second threshold are identified on the battery rack.

[0093] The number of charging modules charging the batteries in each charging compartment on each battery rack is adjusted by increasing the number of charging modules charging the fourth rechargeable battery and decreasing the number of charging modules charging the third rechargeable battery.

[0094] In some embodiments, adjusting the actual charging power of each charging compartment on each battery rack to the charging battery based on the total output power of each charging compartment prioritizing the charging power required by the charging battery with a SOC value greater than a second threshold includes:

[0095] The number of charging modules in each battery rack is determined based on the total output power of the charging compartments in each battery rack.

[0096] Based on the total output power of the charging compartments of each battery rack, the charging power required by the charging batteries with a SOC value greater than the second threshold is prioritized to be met, thereby adjusting the number of charging modules in each charging compartment of each battery rack to charge the batteries.

[0097] The adjustment of the actual charging power of each charging compartment on each battery rack, based on the total output power of each charging compartment prioritizing the charging power required by batteries placed for a duration exceeding a first threshold, includes:

[0098] The number of charging modules in each battery rack is determined based on the total output power of the charging compartments in each battery rack.

[0099] The number of charging modules in each charging compartment of each battery rack is adjusted to prioritize the charging power required by batteries that have been placed for a longer period than a first threshold, based on the total output power of each charging compartment.

[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 output power of the charging compartments of each battery rack. The power of one charging module is P2, and the number of charging modules in the battery rack is P / P2.

[0101] When adjusting the actual charging power of each charging compartment on each battery rack to charge the batteries, the total output power of each charging compartment on each battery rack is prioritized to meet the charging power requirements of charging batteries with a SOC value greater than the second threshold. In this case, the number of charging modules charging the batteries in each charging compartment on the battery rack can be adjusted based on the total output power of each charging compartment on each battery rack prioritizing the charging power requirements of charging batteries with a SOC value greater than the second threshold.

[0102] The method of prioritizing the charging power demand of batteries placed for a duration exceeding a first threshold by prioritizing the total output power of each charging compartment in each battery rack to charge the batteries includes:

[0103] Obtain 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, a first rechargeable battery with a placement time lower than a first threshold and a second rechargeable battery with a placement time higher than the first threshold are determined.

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

[0106] In some embodiments, adjusting the number of charging modules in each charging slot of each battery rack to charge the batteries based on the total output power of each charging compartment of the battery rack prioritizing the charging power required by the rechargeable batteries with a SOC value greater than a second threshold includes:

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

[0108] Based on the SOC value of each rechargeable battery on the battery rack, a third rechargeable battery with an SOC value greater than the second threshold and a fourth rechargeable battery with an SOC value less than or equal to the second threshold are identified on the battery rack.

[0109] The number of charging modules charging the batteries in each charging compartment on each battery rack is adjusted by increasing the number of charging modules charging the third rechargeable battery and decreasing the number of charging modules charging the fourth rechargeable battery.

[0110] In this exemplary embodiment, the number of charging modules charging the batteries in each charging compartment of each battery rack is adjusted by increasing the number of charging modules charging the third rechargeable battery and decreasing the number of charging modules charging the fourth rechargeable battery. This includes:

[0111] Based on the required charging power of each rechargeable battery in 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 in the battery rack is less than the total number of charging modules required for each battery, the number of charging modules for the third battery is increased and the number of charging modules for the fourth battery is decreased. This adjusts the number of charging modules in each charging compartment of each battery rack to charge the batteries, thereby improving the charging and swapping service quality of the battery swapping station.

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

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

[0115] The sum of the number of vehicles currently in the queue for battery swapping at the current battery swapping station and the number of vehicles currently in the queue for battery swapping at the station.

[0116] In this exemplary embodiment, determining the number of vehicles currently waiting for battery swapping includes two parts: one part is the number of vehicles currently in the queue for battery swapping at the station, and the other part is the number of vehicles currently in the queue for battery swapping at the station. The sum of these two parts is used as the number of vehicles currently waiting for battery swapping. This facilitates a more comprehensive estimation of the number of vehicles to be swapped, thereby providing more accurate and reasonable data support for improving the battery swapping service capacity of the station.

[0117] In some embodiments, obtaining the current SOC state of each rechargeable battery on the battery rack includes:

[0118] The current SOC state of the battery to be swapped and the current SOC state of the charging battery on the battery rack that is currently charging are obtained; wherein the battery to be swapped is the battery that was replaced by the vehicle currently to be swapped.

[0119] In this exemplary embodiment, determining the current SOC state of each rechargeable battery on the battery rack includes acquiring the current SOC state of the battery to be swapped and the current SOC state of the rechargeable batteries on the battery rack that are currently charging. That is, each rechargeable battery on the battery rack includes the batteries originally on the battery rack and the batteries removed from the battery swapping vehicle and about to enter the charging compartment.

[0120] In some embodiments, before obtaining the current SOC state of each rechargeable battery on the battery rack, the method includes:

[0121] The charging compartment of the battery to be replaced is determined based on the battery occupancy status of each charging compartment on the battery rack.

[0122] The battery to be replaced is placed in the charging compartment for charging.

[0123] In this exemplary embodiment, when placing the battery removed from the battery swapping vehicle into the charging compartment, the charging compartment of the battery to be swapped can be determined according to the battery occupancy status of each charging compartment on the battery rack. For example, the charging compartments of the battery rack can be numbered and placed sequentially according to the numbering order. For example, the first battery is placed in charging compartment B1, the second battery is placed in charging compartment B2, and so on.

[0164] This disclosure provides a charging and swapping device for a battery swapping station. Figure 7 This is a schematic diagram illustrating the structure of a charging and swapping device in a battery swapping station according to an exemplary embodiment. Figure 7 As shown, the battery swapping station's charging and swapping device utilizes a battery swapping station with multiple battery racks, each rack having multiple charging bays. Each charging bay charges one battery. The device includes:

[0165] The data acquisition module 30 is used to acquire the battery swapping status of the current vehicle to be swapped, the total output power of the charging compartment of each battery rack, and the current SOC status of each charging 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 compartment on the battery rack to the charging battery according to the current battery swapping status of the vehicle to be swapped, the total output power of each charging compartment of the battery rack, and the charging power required by each charging battery on the battery rack.

[0168] In this exemplary embodiment, as Figure 2As shown, the battery swapping station's charging and swapping system includes multiple chargers. Each charger corresponds to multiple charging modules and multiple charging bays, and each charging bay can charge one battery pack. Figure 3 The curves showing the charging power changes corresponding to different battery SOC values ​​indicate that the required charging power varies with each SOC value. The required charging power is the appropriate charging power needed to charge the battery as its SOC value changes.

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

[0170] According to an embodiment of this disclosure, the charging and swapping device for a battery swapping station includes multiple battery racks, each with multiple charging bays, and one charging bay charges one battery. The charging and swapping device is used to: acquire the current battery swapping status of the vehicle to be swapped, the total output power of each charging bay in each battery rack, and the current SOC status of each battery in the battery rack; determine the required charging power for each battery in the battery rack based on the charging power change curve corresponding to the battery SOC status and the current SOC status of each battery in the battery rack; and adjust the actual charging power of each charging bay on the battery rack for the battery according to the current battery swapping status of the vehicle to be swapped, the total output power of each charging bay in each battery rack, and the required charging power for each battery in the battery rack. In this application, to improve the power utilization rate of the total output power of the battery swapping station, during battery charging, the actual charging power of each charging bay on the battery rack for the battery is adjusted based on the current battery swapping status of the vehicle to be swapped, the total output power of each charging bay in each battery rack, and the required charging power for each battery in the battery rack. This helps to improve the power utilization rate of the total output power of the battery swapping station, and thus improves the quality of the charging and swapping services provided by the station.

[0171] In some embodiments, the battery swapping status of the current battery swapping vehicle includes: the number of batteries swapped for the current battery swapping vehicle;

[0172] The power adjustment module is used for

[0173] If the number of batteries to be swapped for the current vehicle is less than the number of batteries in the battery rack that are fully charged, then the actual charging power of each charging compartment on each battery rack is adjusted based on the total output power of the charging compartment of each battery rack prioritizing the charging power required by the batteries that have been placed for a period of less than a first threshold. Alternatively, the actual charging power of each charging compartment on each battery rack is adjusted based on the total output power of the charging compartment of each battery rack prioritizing the charging power required by the batteries that have a SOC value less than a second threshold.

[0174] If the number of batteries to be swapped for a vehicle is greater than or equal to the number of batteries in the battery rack that are fully charged, then the actual charging power of each charging compartment on each battery rack is adjusted based on the total output power of the charging compartment of each battery rack prioritizing the charging power required by batteries with a SOC value greater than a second threshold. Alternatively, the actual charging power of each charging compartment on each battery rack is adjusted based on the total output power of the charging compartment of each battery rack prioritizing the charging power required by batteries that have been placed for a longer period than a first threshold.

[0175] In this exemplary embodiment, when the number of batteries to be swapped for the current vehicle is less than the number of fully charged batteries on the battery rack, it indicates that the available rechargeable batteries on the battery rack meet the current battery swapping needs of the vehicle. In this case, the total output power of each charging bay in the battery rack can be prioritized to meet the charging power requirements of batteries that have been placed for less than a first threshold. For example, the batteries that are most recently connected to the charging bay can be charged with a higher power.

[0176] Wherein, if the number of batteries to be swapped for a vehicle is less than the number of fully charged batteries on the battery rack, the vehicle is swapped, and the method includes:

[0177] When swapping batteries in a battery-swapping vehicle, the first-in, first-out principle is followed. The battery that enters the charging compartment first among the fully charged batteries is selected as the battery for swapping.

[0178] For example, based on the battery placement time and battery rack number within the station, batteries are taken from each battery rack in rotation for battery swapping. Each battery swap takes T1 hours, ensuring that the charging time of the battery pack being swapped this time is staggered from the charging time of the battery pack being swapped last time by approximately T1*n time, where n is greater than or equal to 1.

[0179] In this exemplary embodiment, if the number of batteries to be swapped in the current battery-swapping vehicle is greater than or equal to the number of batteries in the battery rack that are fully charged, it indicates that the available rechargeable batteries in the battery rack cannot meet the current battery-swapping needs of the vehicle. In this case, the total output power of each battery rack's charging compartment can be prioritized to meet the charging power requirements of batteries with a State of Charge (SOC) value greater than a second threshold. This priority includes:

[0180] The total output power of each battery rack's charging compartments can be prioritized to meet the charging power needs of batteries with remaining charging time less than a third threshold. A higher battery SOC value indicates a shorter remaining charging time. The first, second, and third thresholds can all be set manually. This adjustment of actual charging power improves the power utilization rate of the battery swapping station's total output power and enhances its battery swapping service capabilities.

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

[0182] The number of charging modules in each battery rack is determined based on the total output power of the charging compartments in each battery rack.

[0185] The number of charging modules in each charging compartment of each battery rack is adjusted to prioritize charging power for batteries with a SOC value less than a second threshold, based on the total output power of each charging compartment.

[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 output power of the charging compartments of each battery rack. The power of one charging module is P2, and the number of charging modules in the battery rack is P / P2.

[0187] When adjusting the actual charging power of each charging compartment on the battery rack to charge batteries based on the principle that the total output power of each charging compartment of the battery rack should prioritize the charging power required by batteries that have been placed for a short period of time, the number of charging modules in each charging compartment of the battery rack can be adjusted to charge batteries based on the principle that the total output power of each charging compartment of the battery rack should prioritize the charging power required by batteries that have been placed for a short period of time less than a first threshold.

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

[0192] In this exemplary embodiment, adjusting the number of charging modules charging the rechargeable battery in each charging compartment of each battery rack by reducing the number of charging modules charging the second rechargeable battery and increasing the number of charging modules charging the first rechargeable battery includes:

[0193] Based on the required charging power of each rechargeable battery in 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 in the battery rack is less than the total number of charging modules required to charge each battery, the number of charging modules charging the second battery is reduced, and the number of charging modules charging the first 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 for

[0196] The number of charging modules in each battery rack is determined based on the total output power of the charging compartments in each battery rack.

[0197] Based on the principle that the total output power of each charging compartment in each battery rack should prioritize meeting the charging power requirements of batteries with a SOC value greater than a second threshold, the number of charging modules in each charging compartment of each battery rack is adjusted to charge the batteries; or,

[0198] The number of charging modules in each battery rack is determined based on the total output power of the charging compartments in each battery rack.

[0199] The number of charging modules in each charging compartment of each battery rack is adjusted to prioritize the charging power required by batteries that have been placed for a longer period than a first threshold, based on the total output power of each charging compartment.

[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 output power of the charging compartments of each battery rack. The power of one charging module is P2, and the number of charging modules in the battery rack is P / P2.

In this case, the number of charging modules charging the batteries in each charging compartment on the battery rack can be adjusted based on the total output power of each charging compartment on each battery rack prioritizing the charging power requirements of charging batteries with a SOC value greater than the second threshold.

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

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

[0204] Based on the SOC value of each rechargeable battery on the battery rack, a third rechargeable battery with an SOC value greater than the second threshold and a fourth rechargeable battery with an SOC value less than or equal to the second threshold are identified on the battery rack.

[0205] The number of charging modules charging the batteries in each charging compartment on each battery rack is adjusted by increasing the number of charging modules charging the third rechargeable battery and decreasing the number of charging modules charging the fourth rechargeable battery.

[0206] In this exemplary embodiment, the number of charging modules charging the batteries in each charging compartment of each battery rack is adjusted by increasing the number of charging modules charging the third rechargeable battery and decreasing the number of charging modules charging the fourth rechargeable battery. This includes:

[0208] When the number of charging modules in the battery rack is less than the total number of charging modules required for each battery, the number of charging modules for the third battery is increased and the number of charging modules for the fourth battery is decreased. This adjusts the number of charging modules in each charging compartment of each battery rack to charge the batteries, thereby improving the charging and swapping service quality of the battery swapping station.

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

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

[0211] The sum of the number of vehicles currently in the queue for battery swapping at the current battery swapping station and the number of vehicles currently in the queue for battery swapping at the station.

[0212] In this exemplary embodiment, determining the number of vehicles currently waiting for battery swapping includes two parts: one part is the number of vehicles currently in the queue for battery swapping at the station, and the other part is the number of vehicles currently in the queue for battery swapping at the station. The sum of these two parts is used as the number of vehicles currently waiting for battery swapping. This facilitates a more comprehensive estimation of the number of vehicles to be swapped, thereby providing more accurate and reasonable data support for improving the battery swapping service capacity of the station.

[0215] In this exemplary embodiment, determining the current SOC state of each rechargeable battery on the battery rack includes acquiring the current SOC state of the battery to be swapped and the current SOC state of the rechargeable batteries on the battery rack that are currently charging. That is, each rechargeable battery on the battery rack includes the batteries originally on the battery rack and the batteries removed from the battery swapping vehicle and about to enter the charging compartment.
