摘要：PROBLEM TO BE SOLVED: To provide a cooling system for a first PCU for battery charge, wherein temperature increase of the first PCU for battery charge is reduced even if battery charging time becomes longer caused by using AC 100 V.SOLUTION: A cooling system of a first PCU 22 is provided in an electric vehicle 10 having a battery 26, the first PCU 22 for controlling power supplied to the battery 26 when charging the battery 26, and an AC 100 V output device 54 capable of outputting power charged in the battery 26 to an external device. The cooling system comprises a cooling device 32 for supplying cooling water to the first PCU 22 and cooling it down, and a controller 30 for controlling the cooling device 32, wherein when power is outputted from the AC 100 V output device 54 and the battery 26 is being charged, the controller 30 increases the heat quantity that cooling water receives from the first PCU 22 compared to the case when power is not outputted from the AC 100 V output device 54 and the battery 26 is being charged.
