THERMAL MANAGEMENT SYSTEM

A thermal management system includes a first fluid channel, a first electrical energy supply device, a second fluid channel, a first heat exchange device, a power device, a first switching device, a third fluid channel, a compression device, a second heat exchange device, a third heat exchange device, and a first expansion element. The first fluid channel accommodates a first fluid. The first electrical energy supply device exchanges heat with the first fluid. The second fluid channel accommodates the first fluid. The first heat exchange device allows the first fluid to exchange heat with an external environment. The power device exchanges heat with the first fluid. The first switching device separates the first fluid channel from the second fluid channel or connects the first fluid channel with the second fluid channel. The third fluid channel accommodates a second fluid.
