Control device, control method, and non-transitory computer-readable storage medium

A control method of a computer that derives a target parking position of an electric vehicle in a parking space, in a case where electric power is exchanged in a contactless manner between the electric vehicle and a power receiving device including a primary coil installed in the parking space and allowed to supply electric power received by the primary coil to a predetermined power grid, the electric vehicle having a secondary coil,

• the control method comprising:
• acquiring required power information indicating required power, which is a target value of electric power to be supplied to the power grid via the power receiving device;
• and
• deriving the target parking position based on the acquired required power information and power transmission efficiency information indicating power transmission efficiency at each of position relationships between the primary coil and the secondary coil,
• wherein the target parking position at which a second position relationship different from a first position relationship in which the power transmission efficiency is highest is established is derived according to an amount of the required power.

A non-transitory computer-readable storage medium storing a control program causing a computer that derives a target parking position of an electric vehicle in a parking space, in a case where electric power is exchanged in a contactless manner between the electric vehicle and a power receiving device including a primary coil installed in the parking space and allowed to supply electric power received by the primary coil to a predetermined power grid, the electric vehicle having a secondary coil,
