A cooling system has a configuration in which a cooling system for an inverter device and a motor generator also serves as a cooling system for a battery. In this configuration, a control device performs temperature-raising control of the battery when a battery temperature is below a prescribed temperature lower limit value. The control device controls an operation of a switching valve such that cooling water from a cooling medium path is outputted to a bypass path. Further, if a cooling water temperature is lower than a prescribed temperature, the control device controls the inverter device such that a power loss during a switching operation in a switching element included in the inverter device becomes larger than a power loss during normal control. As a result, the cooling system having a small-sized, low-cost configuration rapidly recovers capacity decline of the battery, which occurs at low temperatures.
