Abrégé
(EN)

Charging apparatus 10 includes secondary battery 13 used for buffering, rectifier 11 that supplies direct current power to secondary battery 13 used for buffering, DC-DC converter 14 connected to driving battery 3 in electric vehicle 2 via charging cable 4, switching control circuit 12, and isothermal wind generator 16 that adjusts the temperature of secondary battery 13 used for buffering from outside of secondary battery 13 used for buffering. Switching control circuit 12 switches charging apparatus 10 between a first mode in which power supplied by rectifier 11 is accumulated in secondary battery 13 used for buffering and a second mode in which driving battery 3 is charged with the power supplied by secondary battery 13 used for buffering. Secondary battery 13 used for buffering includes at least one cell in which a battery element with a positive electrode plate and a negative electrode plate that are laminated therein is sealed with an outer cover film.
