The vehicle management method includes acquiring vehicle ID information from the electric vehicle by using the management server; determining the vehicle ID information to be valid if the vehicle ID information acquired falls within a use period set in advance and determining the vehicle ID information to be invalid if the vehicle ID information acquired falls outside a use period set in advance; and applying a prescribed limitation to charging of a battery of the electric vehicle having the vehicle ID information upon determining that the vehicle ID information is invalid. ## Claims ### Claim 1 A vehicle management method for managing an electric vehicle by using a management server based on vehicle-specific ID information that defines a condition of use transmitted from an onboard controller, the vehicle management method comprising: acquiring vehicle ID information from the electric vehicle by using the management server; determining the vehicle ID information to be valid if the vehicle ID information acquired falls within a use period set in advance and determining the vehicle ID information to be invalid if the vehicle ID information acquired falls outside the use period set in advance; and allowing limited charging of a battery of the electric vehicle having the vehicle ID information, using a prescribed limitation on the limited charging of the battery, upon determining that the vehicle ID information is invalid. ### Claim 2 (depends on 1) The vehicle management method according to claim 1, wherein upon the allowing limited charging of the battery using the prescribed limitation, charging is permitted until a remaining charging amount of the battery reaches a predetermined threshold value, and charging is prohibited when the remaining charging amount of the battery reaches the predetermined threshold value. ### Claim 3 (depends on 2) The vehicle management method according to claim 2, wherein charging power from an external power source to the battery is used to carry out system protection of the battery during charging to the battery, and the system protection of the battery is stopped when the charging becomes prohibited. ### Claim 4 (depends on 2) The vehicle management method according to claim 2, wherein charging power from an external power source to the battery is used to carry out system protection of the battery during charging to the battery, and when the charging becomes prohibited, the charging of the battery is stopped while execution of the system protection of the battery using the external power source is continued. ### Claim 5 (depends on 2) The vehicle management method according to claim 2, wherein when a charging gun that supplies electric power from an external power source is disconnected from the electric vehicle after the charging becomes prohibited, a stored power in the battery is used to carry out the system protection of the battery. ### Claim 6 (depends on 2) The vehicle management method according to claim 2, wherein if the prescribed limitation is imposed on the charging of the battery of the electric vehicle, when the charging becomes prohibited a user of the electric vehicle is notified of a charging prohibition state. ### Claim 7 (depends on 1) The vehicle management method according to claim 1, wherein rapid charging is prohibited if the prescribed limitation is imposed on the charging of the battery of the electric vehicle. ### Claim 8 (depends on 1) The vehicle management method according to claim 1, wherein upon determining that the vehicle ID information acquired is invalid, a connection notification sound of a charging gun that supplies electric power from an external power source is made to differ from the sound emitted when the charging gun is normally connected. ### Claim 9 A vehicle management device comprising: an onboard controller for transmitting vehicle-specific ID information that defines a condition of use; and a management server for managing an electric vehicle based on vehicle ID information received, the management server being configured to: acquire the vehicle ID information from the electric vehicle, determine the vehicle ID information acquired to be valid if the vehicle ID information acquired falls within a use period set in advance and determine the vehicle ID information acquired to be invalid if the vehicle ID information acquired falls outside the use period set in advance, and allow limited charging of a battery of the electric vehicle having the vehicle ID information, using a prescribed limitation on the limited charging of the battery, upon determining that the vehicle ID information is invalid.
