Abstract: Provided is a sharing system for a plurality of users to share an electric moving body. The electric moving body comprises a second holder which detachably holds a user battery owned by a user who has rented the electric moving body. The sharing system comprises an authentication unit which acquires a battery ID from the user battery mounted to the second holder and determines whether or not the acquired battery ID and a registered ID registered in advance match each other to thereby authenticate the user who uses the electric moving body.

Abstract: This sharing system shares an electric moving body between a plurality of users. The electric moving body comprises a vehicle body, a driving source that outputs driving force for the traveling of the vehicle body, and a main battery installed in the vehicle body by a provider of the sharing system. Moreover, an ECU of the electric moving body supplies power from a user battery provided by a user who has borrowed the electric moving body to the main battery.

Abstract: This sharing system has a plurality of electric mobile bodies, to which power from one or more batteries is supplied, and is shared by a plurality of users. The one or more batteries include a user battery held by a user. When a user requests to use an electric mobile body, a management server acquires the remaining battery capacity or the maximum output power of the user battery, extracts, on the basis of the acquired remaining battery capacity or the maximum output power of the user battery, information about the user-available electric mobile body, and provides the user with the information about the electric mobile body.
