Abstract
A detection device configured to detect a decrease in heat insulation performance of a battery pack mounted at an electrically powered vehicle, the detection device including: a heat insulation performance derivation unit configured to derive a heat insulation performance value, which is an evaluation value of the heat insulation performance, based on a temperature change of the battery and an environmental temperature in a predetermined period in which the electrically powered vehicle is stopped; a determination unit configured to determine, based on the heat insulation performance value derived by the heal insulation performance derivation unit and a predetermined reference value, whether the decrease in the heat insulation performance occurs; and an output unit configured to output, when the determination unit determines that the decrease in the heat insulation performance occurs, detection information indicating that the decrease in the heat insulation performance occurs.
