1. A thermal management system mounted on an electrical apparatus, the thermal management system comprising:
a first flow path, a second flow path, a third flow path, and a fourth flow path, each configured to allow a heat medium to flow through;
an electrical storage device configured to exchange heat with the heat medium in the first flow path;
a drive device configured to exchange heat with the heat medium in the second flow path and to supply a driving force to the electrical apparatus;
a radiator provided on the third flow path;
a chiller device provided on the fourth flow path;
a switching device configured to switch a connection state among the first flow path, the second flow path, the third flow path, and the fourth flow path, wherein the switching device is configured to form a heating circuit when heating the electrical storage device by causing a current to flow through the electrical storage device, the heating circuit being a flow path circuit in which a connection flow path connecting the first flow path and the fourth flow path is formed; and the connection flow path, the second flow path, and the third flow path are disconnected from and independent of each other, and
the first flow path, the second flow path, the third flow path, and the fourth flow path are independently controlled by the switching device.
