Document Type and Number:
WIPO Patent Application WO/2023/179232
Kind Code:
A1
Abstract:
Disclosed in the embodiments of the present application are a temperature management device and a test system. The temperature management device is used for performing temperature management on a battery pack which is cooled by a refrigerant, and the temperature management device comprises: a first interface, which is used for being detachably connected to a refrigerant outlet of a battery pack; a second interface, which is used for being detachably connected to a refrigerant inlet of the battery pack; a compressor; a condenser; an expansion valve, wherein a first outlet of the expansion valve is connected to the second interface; and a pressure regulating valve, wherein a first end of the pressure regulating valve is connected to the first interface, a second end of the pressure regulating valve is connected to an inlet of the compressor, and the pressure regulating valve is used for regulating the pressure of a gas which is discharged from the refrigerant outlet of the battery pack, so that a pressure value of the gas which is discharged from the second end of the pressure regulating valve to the inlet of the compressor is within a preset range. By means of the temperature management device and the test system in the embodiments of the present application, a battery pack can be kept at a stable and suitable temperature during a test process of the battery pack.
