To provide a temperature control circuit and a control method therefor, capable of efficiently heating a battery.SOLUTION: A temperature control circuit 1 includes a first temperature adjustment circuit 4 for performing heat exchange with a battery 2. The first temperature adjustment circuit 4 comprises: a first pump EWP1 for making a heating medium circulate; a feedback passage 18 bypassing the battery 2; a heater 19 disposed on the feedback passage 18; a first connection part 21 connecting the feedback passage 18 with an upstream side flow passage 20 positioned on the upstream side of the battery 2 in a flow direction of the heating medium passing through the battery 2; and a second connection part 23 connecting the feedback passage 18 with a downstream side flow passage 22 positioned on the downstream side of the battery 2 in the flow direction of the heating medium. At the first connection part 21, the upstream side flow passage 20 is connected with the feedback passage 18 via an ejector 24.SELECTED DRAWING: Figure 1
