A Rankine cycle system (101) mounted on a vehicle has a Rankine cycle circuit (100) through which working fluid circulates, a power generator, a power storage and a controller. The Rankine cycle circuit includes a fluid expansion device (114), a fluid transferring device (111), first and second passages (1,2), a heater (112,113), a cooling device (115), a bypass passage (3) and a flow regulating valve (120). The bypass passage connects the first passage to the second passage. The flow regulating valve is provided in the bypass passage for opening and closing the bypass passage. The power generator (116) converts the work generated by the fluid expansion device into electric power. The controller (119) monitors charge rate of the electric power charged in the power storage and controls an operation of the flow regulating valve based on the monitored charge rate. The controller causes the flow regulating valve to be opened when the monitored charge rate is greater than a predetermined value.
