1. A vehicle comprising:
a battery;
an air conditioner;
a first temperature adjustment circuit including a first pump configured to supply a heat medium to the battery, and a first heat exchange unit configured to exchange heat between the heat medium and a heat medium for air conditioning;
a second temperature adjustment circuit including a second pump configured to supply the heat medium to a power conversion device, and a second heat exchange unit configured to exchange heat between the heat medium and an outside air;
a coupling passage configured to connect the first temperature adjustment circuit and the second temperature adjustment circuit to form a coupling circuit;
a switching unit configured to switch between a circulation state, in which the heat medium is capable of circulating through the coupling circuit, and a non-circulation state, in which the heat medium is not capable of circulating through the coupling circuit;
a first temperature acquisition unit configured to acquire a first temperature which is a temperature of the battery; and
a control device configured to select any one mode of a plurality of modes,
wherein the plurality of modes include:
a series mode in which, in the circulation state, the heat medium is circulated in the coupling circuit in a state in which the first heat exchange unit is not capable of exchanging heat between the heat medium and the heat medium for air conditioning;
a separate mode in which the heat medium is circulated in the second temperature adjustment circuit in the non-circulation state; and
a parallel cooling mode in which, in the non-circulation state, the heat medium is circulated in the second temperature adjustment circuit, and the heat medium is circulated in the first temperature adjustment circuit in a state in which the first heat exchange unit is capable of exchanging heat between the heat medium and the heat medium for air conditioning, and
wherein the control device selects the any one mode of the plurality of modes in accordance with the first temperature.
