PROBLEM TO BE SOLVED: To provide a power regeneration system for fan motor for vehicle capable of regenerating power generated in a fan motor efficiently.SOLUTION: A power regeneration system 1A for fan motor for vehicle includes: a power storage part 12 in which a charge voltage is lower than that of a battery 2 and which can charge/discharge regenerative electric power generated by a fan motor 5; and a converter 14 for boosting the power supplied from the power storage part 12 to the voltage which can be charged more efficiently than the case where charging is performed at the charge voltage of the power storage part 12 to the battery 2 and for supplying it to the battery 2. At non-driving time of the fan motor 5, the power storage part 12 is charged by the regenerative electric power generated by the fan motor 5, and during driving time of the fan motor 5, power is supplied to the converter 14 from the power storage part 12, and the battery 2 is charged by the power boosted by the converter 14.SELECTED DRAWING: Figure 1 【課題】ファンモータで発生する電力を効率良く回生することができる車両用ファンモータの電力回生システムを提供する。【解決手段】車両用ファンモータの電力回生システム１Ａは、バッテリ２よりも充電電圧が低く、ファンモータ５により発電される回生電力の充放電が可能な蓄電部１２と、蓄電部１２から供給される電力を、バッテリ２に蓄電部１２の充電電圧で充電した場合よりも、効率が良く充電可能な電圧に昇圧してバッテリ２に供給するコンバータ１４と、を備え、ファンモータ５の非駆動時に、ファンモータ５により発電された回生電力により蓄電部１２を充電し、ファンモータ５の駆動時に、蓄電部１２からコンバータ１４に電力を供給し、コンバータ１４で昇圧される電力によりバッテリ２を充電する。【選択図】図１
