1. A failure prediction system comprising:
an obtainer which obtains travel data of an electric vehicle; and
a predictor which predicts, based on the travel data of the electric vehicle, a failure due to aging in a drive circuit of a motor which drives a driving wheel of the electric vehicle,
wherein the travel data includes position data of the electric vehicle and data relating to power consumption of the electric vehicle, and
the predictor predicts the failure due to aging in the drive circuit based on a change in an increase of power consumption amount generated when the electric vehicle travels a same route.
