Abstract
A cooling system includes a shared path; a first path connected to the shared path and having a first pump and a first heat exchanger exchanging heat with an inverter; a second path connected to the shared path in parallel with the first path and having a second pump and a second heat exchanger exchanging heat with a battery. The first and second paths are configured to be able to switch a flow state between a first state where the heat media flow through the shared path, and a second state where one of the heat media does not flow through the shared path. The control device controls the outputs of the pumps so that when switching the flow state between the first and second states, flow rate of the heat medium flowing through the first path becomes temporarily larger than the target flow rate.
