A bicycle battery 17 can be directly connected to charge the bicycle battery 17.

  In addition, since the power supplied to the charging outlet 14 and the lighting device 13 is generated by the solar power generation panel 12, the environmental load is small and the user can easily use it.

  Furthermore, when the amount of power stored in the bicycle parking battery 23 is small, the battery can be charged with inexpensive late-night power. Therefore, it is possible to suppress the charging cost.

  In addition, the bicycle parking lot 10 which concerns on this invention is not limited to embodiment mentioned above, A various deformation | transformation and application are possible. For example, without providing the bicycle parking battery 23 in the bicycle parking lot 10, when a necessary amount of power cannot be secured by the power generated by solar power generation, the power supply may be directly received from the outside. When such a configuration is adopted, the bicycle parking battery 23, the second wattmeter 24, and the voltmeter 26 can be deleted.

  In addition, although the present invention has technical features of a facility as a bicycle parking lot, its configuration and use are not only as a bicycle parking lot equipped with the above-described electric assist bicycle charging facility, but also an electric cart used in a golf course, Needless to say, the present invention can also be applied to a parking facility equipped with a battery charging facility such as an electric shuttle car operated in an outdoor amusement park or the like.

  Furthermore, as an additional configuration, information regarding the daytime weather forecast can be input to the control device 30 regardless of whether it is wireless or wired, so that the power generation amount of the photovoltaic power generation panel 12 can be predicted. The shortage of the power generation amount predicted by the solar power generation panel 12 may be made to depend on the supply of midnight power in advance.
