[Third Embodiment] In the third embodiment, an arrangement example in which the first area 1A for selling beverage products and the second area 2A for exchangeably providing the battery 180 are arranged in the vending machine 100 will be described. The vending machine 100 of the third embodiment has, for example, a configuration including the 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 charging and discharging device according to external power, and can supply power to an external device. The charging and discharging station 600 (power supply device) can be used as an external device to The vending machine 100 supplies power.

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

As shown in FIG. 7 , in the first area 1A, beverage products are loaded into the storage rack 701 corresponding to the type of the product, and the beverage products are held in the storage rack 701 when the holding portion 702 is closed. When a product is selected, the holding part 702 of the selected beverage product is controlled to be opened, and a predetermined number of beverage products are guided by the guide 703 to the take-out part 117 for taking out the beverage and food.

As shown in FIG. 7 , the replacement slot 180B is provided so that the battery can be exchanged through a first opening formed on the front side of the power supply device, and the fixing slot 180C is provided at a position corresponding to the replacement slot 180B. The side opposite to the first opening (back side). As shown in FIG. 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 in a space separated from the front side to the back side of the power supply device or the vending machine 100 . Location. An openable and closable door (not shown) is provided at the opening of the replacement slot 180B. Normally, the door is in a closed state. When the liquidation process is completed, any one of the openings of the replacement slots 180B is closed. It is in the open state so that the battery can be removed. When the battery is removed and refilled with an uncharged battery, or a battery with a lower charging level due to use, the charged battery will be charged.

The fixing slot 180C is provided so that the battery held in the fixing slot 180C can be exchanged from the second opening formed in the power supply device (charging/discharging station 600 ). A door (not shown) is also provided in the second opening of the fixing slot 180C, but the door is normally closed by a fastening member such as a bolt. When the battery needs to be maintained, the fastening member can be removed and the door can be opened so that the battery can be exchanged. Since the battery held in the fixing slot 180C is not an object to be exchanged by the user of the electric vehicle, the fixing slot 180C can be formed at a position that is less accessible to the user than 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. 7 . For example, the fixing slot 180C may be provided on the lower side of the power supply device (charging/discharging station 600 ), The replacement slot 180B is disposed above the power supply device (charging/discharging station 600 ) than the position of the fixing slot 180C. Conversely, the fixing slot 180C may be provided in the vicinity of the lowermost edge close to the ground, and the replacement slot 180B may be provided above it. That is, it is desirable to provide the replacement slot 180B at a place where the user of the electric vehicle can easily exchange the battery when the battery is exchanged. In addition, the fixed slot 180C may be provided, for example, on the upper part of the vending machine 100 , and the replacement slot 180B may be provided in the space below the storage rack 701 . Thereby, more slots 180B for replacement can be provided below the storage rack 701 , that is, in a place where the user of the electric vehicle can easily use.

The battery held in the replacement slot 180B and the battery held in the fixed slot 180C have the same structure but different electrical states. Since it is not an object of exchange by the user of the electric vehicle, the battery held in the fixing slot 180C is held in a state in which power can be supplied without input of an activation signal for activating the battery. Since the battery held in the replacement slot is to be exchanged by the user of the electric vehicle, it is held in a state in which power cannot be supplied without an activation signal being input. In this way, by changing the electrical state at the time of holding, it is possible to prevent incorrect discharge or the like. As a method of changing the electrical state, the control program may be changed automatically when the battery is set in the fixing slot.

In addition, the battery held in the fixed slot 180C and the battery held in the replacement slot 180B differ in the degree of full charge capacity of the battery, which is an electrical characteristic. For example, the battery held in the fixed slot 180C is a more degraded 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 having the same structure but different in full charge capacity and the like is limited to those used in electric vehicles (batteries held in replacement slots) and those used only for supplying power to external devices ( The battery held in the fixed slot) can be used effectively and flexibly.

The power control unit 350 of the power supply device (charging/discharging station 600 ) can use the battery held in the fixed 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 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 according to the time information set by the terminal device 150 . In addition, the power control unit 350 charges the battery held in the replacement slot 180B by supplying power from the battery held in the fixed slot 180C, and controls the battery held in the fixed slot 180B according to the set time information. The charging state of the battery in slot 180C is switched.

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

In addition, the power supply device (charging/discharging station 600 ) includes a sensor 404 that detects whether the power from an external power source (eg, the power system 400 ) is in a power failure state. The power control unit 350 can control the power supply to the vending machine 100 or the power supply method for charging the battery held in the replacement slot 180B according to the power of the battery held in the fixed slot 180C. In addition, in such a case, power may be supplied in priority to functions such as the holding portion 702 for supplying beverage products accommodated in the vending machine, and the temperature control portion for adjusting the temperature may not be supplied. 320 and the temperature adjustment unit 330 supply power. Thereby, even in the event of a power failure or the like, beverage products can be provided for a long time.
