Control device for electric flight vehicle and non-transitory computer readable medium storing computer program for electric flight vehicle

A control device for an electric flight vehicle configured to control the electric flight vehicle and provided in the electric flight vehicle, the electric flight vehicle having a rotary wing driven by electric power of a battery and configured to rotate and cause the electric flight vehicle to fly, the control device comprising:

• a temperature acquisition unit configured to acquire a temperature of the battery as a battery temperature;
• a take-off restriction unit configured to place restriction on take-off of the electric flight vehicle when the battery temperature acquired by the temperature acquisition unit is lower than a take-off permitting temperature that is a temperature for permitting take-off of the electric flight vehicle;
• a battery temperature raising unit configured to perform battery temperature raising processing for raising the battery temperature when the restriction is placed on take-off of the electric flight vehicle by the take-off restriction unit;
• a restriction termination unit configured to terminate the restriction placed on take-off of the electric flight vehicle when the battery temperature exceeds a restriction terminating temperature and the battery temperature raising processing is performed by the battery temperature raising unit, the restriction terminating temperature being higher than the take-off permitting temperature;
• and
• a drive device configured to receive electric power from the battery to drive the rotary wing to rotate, wherein
• the rotary wing of the electric flight vehicle is one of at least four rotary wings,
• the battery temperature raising unit is configured to set a target output, which is related to the rotary wing, such that the rotary wing is driven to rotate at a number of rotations to generate thrust that does not cause the electric flight vehicle to ascend, and
• a drive execution unit is configured to drive the drive device such that at least two of the rotary wings are driven at the target output to rotate to raise the battery temperature.
