[0067] If the energy storage module's power supply meets the daily load power supply, then the energy storage module supplies power to the electric vehicle and updates the remaining power storage capacity of the energy storage module.

[0068] If the energy storage module's power capacity is insufficient to meet the daily load of the electric vehicle, then electricity will be purchased from the distribution network.

[0069] In this embodiment of the invention, optionally, the step of purchasing electricity from the distribution network if the energy storage module's power capacity is insufficient to meet the daily load power of the electric vehicle further includes:

[0070] Determine whether the energy storage module's power level is less than a power threshold;

[0071] If the energy storage module's power is less than the power threshold, then it is determined whether the power price of the distribution network is within an acceptable range;

[0072] If the electricity price of the distribution network is within an acceptable range, electricity is purchased from the distribution network and stored in the energy storage module, and the remaining energy storage capacity of the energy storage module is updated.

If the electricity price of the distribution network is not within an acceptable range, no electricity is purchased from the distribution network, and the remaining energy storage capacity of the energy storage module is directly updated.

[0075] Please refer to Figure 4In this embodiment of the invention, the predicted daily hydrogen storage capacity and the daily hydrogen consumption required by hydrogen fuel cell vehicles are obtained; it is determined whether the daily hydrogen storage capacity can meet the daily hydrogen consumption of all hydrogen fuel cell vehicles; if the daily hydrogen storage capacity can meet the daily hydrogen consumption of all hydrogen fuel cell vehicles, the remaining hydrogen storage capacity is directly updated; if the daily hydrogen storage capacity cannot meet the daily hydrogen consumption of all hydrogen fuel cell vehicles, the remaining electricity needs to be obtained from the daily power generation; simultaneously, the daily power generation of the new energy power generation device and the daily load power of electric vehicles are predicted; it is determined whether the daily power generation can meet the daily load power of all electric vehicles; if it can, if there is still remaining electricity after the daily power generation meets the daily load power, the remaining electricity is obtained as the first remaining electricity reserved for the hydrogen production module for water electrolysis to produce hydrogen; the new energy power generation is given the highest priority to charge electric vehicles, the second highest priority to use for water electrolysis to produce hydrogen, and the remainder is stored in the battery pack; and the remaining electricity storage capacity is updated; if the daily power generation... If the daily power load of all electric vehicles cannot be met, the system determines whether the battery pack in the energy storage module can meet the power requirements of the remaining electric vehicles. If it can, the battery pack provides power to the remaining electric vehicles and updates the stored power in the battery pack. If it cannot, power is purchased from the distribution network to provide power to the remaining electric vehicles. The system then determines whether the remaining stored power in the battery pack is less than a threshold. If the remaining stored power in the battery pack is not less than the threshold, there is no need to purchase power from the distribution network. If the remaining stored power in the battery pack is less than the threshold, the system determines whether the electricity price in the distribution network is within an acceptable range. If the energy storage in the battery pack is insufficient and the electricity price in the distribution network is within an acceptable range, power is purchased from the distribution network and stored in the energy storage module, updating the remaining stored power in the energy storage module. If the electricity price in the distribution network is not within an acceptable range, no power is purchased from the distribution network, and the remaining stored power in the energy storage module is updated directly.

[0076] Please refer to Figure 5 In this embodiment of the invention, natural gas and gasoline provided by an external entity are also connected to the vehicle charging service station. During the day-ahead scheduling, the daily oil and gas storage volume is obtained; the required oil and natural gas volume for fuel vehicles and natural gas vehicles is estimated; and it is determined whether the daily oil and gas storage volume can meet the oil and natural gas volume of all fuel vehicles and natural gas vehicles. If it can, the daily oil and gas storage volume is updated; if it is insufficient to supply the natural gas and fuel load of natural gas vehicles and fuel vehicles for the next day, it needs to be purchased in a timely manner.

[0077] In this embodiment of the invention, multiple energy sources are uniformly managed by the vehicle charging service station to accommodate charging services for electric vehicles, hydrogen fuel cell vehicles, gasoline vehicles, natural gas vehicles, and even vehicles supplied with hybrid energy.

[0078] In this embodiment of the invention, by designing charging service stations for vehicles with multiple energy consumption types, the charging needs of various vehicles are met. The day-ahead scheduling of the charging service stations is also designed, so that the charging service stations can determine the energy source and energy destination through the scheduling mechanism, thereby realizing the rational scheduling of multiple energy sources and meeting energy needs.
