For example, the parking facility operation device 40 includes an electrical characteristic conversion for storing and supplying electric power, And monitoring of the amount of electric power in the battery.

On the other hand, in the case of a hydrogen fuel cell vehicle, it is different from a general battery type electric vehicle in that, when the supply of hydrogen is continued, electric power can be produced without supplying power to the power grid.

When the hydrogen fuel cell vehicle is used as an energy source, unlike an electric vehicle, there is no additional power supply. For example, a power supply of about 100 Kw per one vehicle can be supplied. It is possible to supply power of 1MW class.

Accordingly, an embodiment of the present invention proposes a new method for utilizing the generated power in the hydrogen fuel cell vehicle as an energy source for charging the electric vehicle due to the above-described differentiation of the hydrogen fuel cell vehicle, The construction of the parking facility operation device 40 for realizing this will be described in detail.

In this case, the mandatory power generation time refers to a length of time determined by the controller 44 in consideration of the remaining amount of hydrogen remaining in the hydrogen tank of the parked hydrogen fuel cell vehicle and the amount of power stored in the energy storage system 30, It can be understood that the remaining amount of hydrogen is consumed and is the time until reaching the predetermined minimum amount of maintenance for normal operation of the vehicle.

When the hydrogen fuel cell vehicle is parked, the control unit 44 confirms the remaining amount of hydrogen remaining in the hydrogen tank of the hydrogen fuel cell vehicle. If the amount of the residual hydrogen that has been confirmed exceeds the predefined minimum holding amount , The average power supply amount to be supplied for charging the electric vehicle to the electric vehicle charging facility 20 for a unit time (for example, 24 hours) after the parking is made is set to a threshold ratio with respect to the electric energy storage amount of the current energy storage system 30 The parked hydrogen fuel cell vehicle is maintained in the power generation state during the obligatory power generation time.

Here, the electric power generation state in the hydrogen fuel cell vehicle refers to a state in which hydrogen and air are supplied to the fuel cell stack and electric power is being generated from the fuel cell stack, and the average electric power to be supplied for charging the electric vehicle for a unit time The fact that the supply amount exceeds the critical ratio with respect to the power storage amount of the present energy storage system 30 means that electric power is not generated in the hydrogen fuel cell vehicle, It can be understood that the amount of power that can be supplied to the battery 20 is not sufficient.

On the other hand, the remaining hydrogen amount confirmation and power generation state maintenance for the hydrogen fuel cell vehicle described above can be handled, for example, via CAN communication between the control unit 44 and the hydrogen fuel cell vehicle.

Here, the amount of electric power to be supplied to the electric vehicle charging facility 20 may vary depending on the number of electric vehicles requiring charging and the specifications of the electric vehicles.

On the other hand, when it is determined that the power generation progress vehicle does not exist, the determination unit 42 determines that only the power supply path (1) from the energy storage system 30 to the electric vehicle charging facility is included as shown in FIG. 5 The energy stored in the energy storage system 30 can be supplied for charging the electric vehicle irrespective of the parking facility 10 by determining the energy transfer path.

The processing section 43 performs a function of processing power supply.

More specifically, when the determination of the energy transfer path considering the presence of the generation electric power vehicle and the generated electric power amount is completed, the processing unit 43 processes the electric power supply through the determined energy transfer path, To charge the electric vehicle supplied with electric power along the transmission path or to store or discharge electric power in the energy storage system 30.
