The vending machine 100 of the third embodiment is, for example, a structure having a charging and discharging station 600 described in FIG. 6 inside. The charging and discharging station 600 is a power supply device that can charge the battery 180 held in the charger and discharger according to external power and can supply power to external devices. The charging and discharging station 600 (power supply device) can be used as an external device. The vending machine 100 supplies electric power.

Fig. 7 is a diagram showing a schematic configuration of the vending machine 100 of the third embodiment. The power supply device has a replacement slot 180B, which holds the battery for replacement, and a fixed slot 180C, which holds the battery that does not exchange but only supplies power to an external device (the vending machine 100).

As shown in FIG. 7, in the first zone 1A, the beverage products are loaded in the storage rack 701 corresponding to the type of the product, and when the holding portion 702 is closed, the beverage products are held in the storage rack 701. When a product is selected, it is controlled by opening the holding part 702 of the selected beverage product, and the guide 703 guides a predetermined number of beverage products to the takeout part 117 for taking out the beverage and food.

As shown in FIG. 7, the replacement slot 180B is set to allow the battery to be exchanged from the first opening formed on the front side of the power supply device, and the fixing slot 180C is provided in the replacement slot 180B. The side opposite to the first opening (back side). As shown in Figure 7, when the power supply device (charging and discharging station 600) or the vending machine 100 is viewed from the side, the fixing slot 180C is provided at a distance from the front side of the power supply device or the vending machine 100 to the back side. Location. The opening of the replacement slot 180B is provided with a door that can be opened and closed. Normally, the door is in a closed state. When the liquidation process is completed, any one of the openings of the plurality of replacement slots 180B Be in an open state so that the battery can be taken out.

When the battery needs to be maintained, the fastening member can be removed to make the door open so that the battery can be exchanged. Since the battery held in the fixing slot 180C is not the object of exchange by the user of the electric vehicle, the fixing slot 180C can be formed in a position that is not easily accessible to the user compared to the replacement slot 180B.

Furthermore, the positional relationship between the replacement slot 180B and the fixing slot 180C is not limited to the configuration shown in FIG. The replacement slot 180B is arranged above the power supply device (charge and discharge station 600) than the position of the fixed slot 180C. Conversely, the fixing slot 180C may be provided near the bottom side near the ground, and the replacement slot 180B may be provided above it.

In addition, the battery held in the fixing slot 180C and the battery held in the replacement slot 180B are different in the full charge capacity of the battery as an electrical characteristic. For example, the battery held in the fixing slot 180C is a more deteriorated battery than the battery held in the replacement slot 180B. In other words, the full charge capacity of the battery held in the fixed slot is a battery with a lower full charge capacity than the battery held in the replacement slot. In this way, the use of batteries that have the same structure but differs in full charge capacity, etc., is limited to those used in electric vehicles (batteries held in the replacement slot) and those used only to supply power to external devices ( Keep the battery in the fixed slot) and use it, which can be effectively and flexibly used.

The power control unit 350 of the power supply device (charging and discharging station 600) can use the battery held in the fixing slot 180C more preferentially than the battery held in the replacement slot 180B to control the power supply to the external device. In addition, the power control unit 350 can switch between the control of the charging of the battery held in the replacement slot 180B and the power supply from the battery held in the fixed slot 180C based on the time information set by the terminal device 150. In addition, the power control unit 350 performs charging of the battery held in the replacement slot 180B by supplying power from the battery held in the fixing slot 180C, and on the condition that the battery held in the fixing slot 180B is charged based on the set time information. Switch the status of charging the battery in slot 180C.

The power supply device (charging and discharging station 600) is equipped with a monitoring unit (for example, sensors 404, 406, and sensor 413) that monitor the power required for the vending machine 100, and the power required for the vending machine 100 is greater than that In the case of the reference power, the power control unit 350 may also perform control such that power is supplied to the vending machine 100 from the battery held in the fixing slot 180C.

In addition, the power supply device (charge and discharge station 600) is equipped with a sensor 404 that detects whether the power from an external power source (for example, the power system 400) is in a power outage state. When the power outage state is detected by the sensor 404, The power control unit 350 can control the method of supplying power to the vending machine 100 or charging the battery held in the replacement slot 180B based on the power of the battery held in the fixing slot 180C. In addition, in this case, it can also be set to supply electric power more preferentially than the function of the holding unit 702 for providing beverage products contained in the vending machine, and not to adjust the temperature of the temperature control unit 320 and the temperature adjustment unit 330 supply electric power. In this way, even in the event of a power outage and other disasters, beverage products can be provided for a long time.
