Abstract: A system includes: a compressor; a heat-releasing flow path including a heat-releasing member having and an inlet connected to an outlet of the compressor; a heat-absorbing flow path including a throttling apparatus and a heat-absorbing member; and a battery thermal management flow path An inlet of the throttling apparatus is connected or disconnect with an outlet of the heat-releasing member. An outlet of the throttling apparatus is connected to an inlet of the heat-absorbing member, and an outlet of the heat-absorbing member is connected to an inlet of the compressor. The battery thermal management flow path includes a battery throttling apparatus and a battery direct-cooling plate. An inlet of the battery throttling apparatus communicates with the outlet of the compressor or the heat-releasing member. An outlet of the battery throttling apparatus connects to an inlet of the battery direct-cooling plate.

Abstract: A contactor for a vehicle, includes: a first wiring terminal, a second wiring terminal, a conducting bar, and a driving assembly. A first conduction section and a second conduction section of the conducting bar are connected to each other and are configured to rotate with respect to each other. The first conduction section is fixed on the first wiring terminal, and the second conduction section is electrically connected to or electrically disconnected from the second wiring terminal. The driving assembly is configured to drive the second conduction section to move toward or away from the second wiring terminal. The first wiring terminal and the second wiring terminal are disposed opposite to the conducting bar in a first direction, the driving assembly is disposed opposite to the conducting bar, or the first wiring terminal, or the second wiring terminal in a second direction different from the first direction.
