[0127] When the current number of the battery-swap batteries is less than the sum of the predicted numbers of battery-swap vehicles corresponding to the current time period and the next time period, the current total power of the energy storage battery is less than the sum of the predicted power required by the charging vehicles corresponding to the current time period and the next time period, and the current total power of the energy storage battery is less than the predicted power required by the charging vehicles corresponding to the next time period, determine that the first charging strategy is to use the AC power supply end to charge the energy storage battery, use the AC power supply end to charge the vehicle located at the vehicle charging position, and use the AC power supply end to charge the second battery compartment;

[0128] It should be noted that, when the current number of the battery replacement batteries is less than the sum of the predicted number of battery replacement vehicles corresponding to the current time period and the next time period, the current total power of the energy storage battery is less than the sum of the predicted power required for charging vehicles corresponding to the current time period and the next time period, and the current total power of the energy storage battery is less than the predicted power required for charging vehicles corresponding to the next time period, the battery replacement batteries and the depleted batteries replaced by the battery replacement vehicles are placed in the second battery compartment and charged using the AC power supply end to meet the battery replacement needs, and the energy storage battery is charged using the AC power supply end until the power of the energy storage battery can meet the predicted power required for charging vehicles in the next time period or is fully charged, and the AC power supply end is used to charge the vehicle located at the vehicle charging position.

[0129] In this embodiment, if Figure 5 As shown, when the current time period is the valley period, since the electricity price is the lowest at this time, all the vehicles are charged using the mains power supply end. When there is a vehicle that needs to be charged at the vehicle charging position, the charging battery corresponding to the charging pile at the vehicle charging position where the vehicle is located is fully charged or reaches a preset charge amount, and the position remains unchanged. If the battery is not moved to the second charging position of the battery swap warehouse or the first charging position of the energy storage warehouse, the mains power supply end is used for charging to ensure that the batteries in the battery swap charging station are fully charged as much as possible during the valley period, thereby saving electricity costs.

[0130] Optionally, in the control method, step S30 includes one or more of the following:

[0131] When the first charging strategy includes using the energy storage battery to charge the vehicle located at the vehicle charging position, controlling the charge and discharge state of the energy storage converter to be a discharge state to the charging pile;

[0133] When the first charging strategy includes using the mains power supply end to charge the energy storage battery, the charge and discharge state of the energy storage converter is controlled to be a state of charging the energy storage battery.

[0134] In this embodiment, according to the first charging strategy, the charging and discharging state of the energy storage converter is changed, so as to reasonably distribute the power of the energy storage battery.

[0135] It should be noted that the embodiment of the present invention realizes the scheduling among battery replacement, energy storage and fast charging, calls different power allocation strategies according to the peak, valley and normal periods, realizes the scheduling between the energy storage battery and the mains power supply end, and ensures that when the energy storage battery is discharged, it will not affect the mains power supply end. And realize the charging / discharging switching of the energy storage warehouse. When the energy storage warehouse supplies power to the outside, it switches to the discharge mode, and when the energy storage warehouse needs to be charged, it switches to the charging mode. The charging warehouse realizes the switching of the charging pile inside / outside the station, and switches through the switching switch device, wherein the charging inside the station is to charge the battery replacement battery, and the charging outside the station is to charge the vehicle located at the vehicle charging position. When the charging pile detects that a vehicle is connected to the external charging gun, the switching switch is controlled to switch the charging pile to charging outside the station to charge the vehicle at the vehicle charging position.

[0136] The cloud platform equipment predicts the battery swapping vehicles and charging vehicles at different times of the day based on the historical data of battery swapping and fast charging, and predicts the charging power required by charging vehicles. These prediction data are sent to the station-side EMS (Energy Management System) in real time for power allocation. The power allocation algorithm is implemented according to the peak, valley and normal periods and the predicted battery swap history data and fast charging history data. During the peak period, the charging and discharging state of the energy storage inverter is determined according to the current number of battery swap batteries and the current total power of the energy storage battery and the predicted number of battery swap vehicles and the power required by the charging vehicles, so as to ensure that the mains power supply end is used as much as possible for charging while meeting the battery swap and charging needs during the peak period; during the normal period, when the next period is the peak period, the current number of battery swap batteries and the current total power of the energy storage battery must meet both the current period demand and the next period demand. If the demand of the next period is not met, charging is allowed at this stage to meet the demand of the next peak period; when the next period is the valley period, the current number of battery swap batteries and the current total power of the energy storage battery only need to meet the current period demand, and wait for the next valley period to fully charge all batteries; during the valley period, the mains power supply end is used for power supply to fully charge the energy storage battery, fully charge the batteries in the battery compartment corresponding to the charging pile, and immediately charge the low-power batteries replaced on the vehicle to ensure that the number of battery swap batteries and the current total power of the energy storage battery in the battery swap station reach the maximum before the next period. Through the historical data on battery swapping and charging collected by cloud platform equipment, the number of battery swapping vehicles, the number of charging vehicles and the amount of charge required for charging vehicles in each time period are predicted; by integrating charging pile warehouses and energy storage warehouses into battery swap stations, the number of charging modules is reduced, the construction land is reduced, and thus the cost of station construction is saved; through the power allocation algorithm in each time period, the price difference between peak, valley and flat electricity is utilized to achieve maximum profit.
