Thermal management system of electric vehicle and electric vehicle

Abstract

The embodiment of the invention provides a thermal management system of an electric vehicle and the electric vehicle. A thermal management system of an electric vehicle includes: a low-pressure stage compressor; an air suction port of the high-pressure-stage compressor is connected with an exhaust port of the low-pressure-stage compressor; an inlet of the internal condenser is connected with an exhaust port of the high-pressure stage compressor; the intercooler is provided with a first inlet, a first outlet, a second inlet and a second outlet, an outlet of the internal condenser is connected with the first inlet, and an air suction port of the high-pressure stage compressor is connected with the second outlet; an inlet of the first expansion valve is connected with an outlet of the internal condenser, and an outlet of the first expansion valve is connected with the second inlet; an inlet of the second expansion valve is connected with the first outlet; an inlet of the evaporator is connected with an outlet of the second expansion valve, and an air suction port of the low-pressure-stage compressor is connected with an outlet of the evaporator. According to the thermal management system, the problem of insufficient refrigerating capacity can be solved.

Description

technical field [0001] The embodiments of the present application relate to the technical field of electric vehicles, and in particular to a thermal management system of the electric vehicle and the electric vehicle. Background technique [0002] With the continuous development of science and technology, high-power and large-capacity batteries are gradually realized in mass production, thus promoting the rapid development of electric vehicles using such batteries. Compared with traditional fuel vehicles, electric vehicles have obvious advantages in terms of energy security, environmental protection and sustainable development, so electric vehicles are gradually replacing traditional fuel vehicles. Since the power structure of electric vehicles is different from that of transmission fuel vehicles, the thermal management system of electric vehicles is also significantly different from that of traditional fuel vehicles. In a high-temperature environment, electric vehicles need...
