Integrated heat pump management system for pure electric vehicle and pure electric vehicle

Abstract

The invention discloses an integrated heat pump management system for a pure electric vehicle and the pure electric vehicle. The system comprises a compressor, a compartment exterior heat exchanger, acompartment inner heat exchanger, a battery cold plate, and a four-way valve which comprises four valve ports; the first valve port is communicated with an outlet of the compressor; the third valve port communicates with an inlet of the compressor; the compartment exterior heat exchanger, the compartment inner heat exchanger and the battery cold plate are arranged between the second valve port and the fourth valve port, the compartment inner heat exchanger and the battery cold plate are connected in parallel and then connected with the compartment exterior heat exchanger in series, and valvesfor controlling the opening and closing states of the corresponding connecting pipelines are arranged on the connecting pipelines for connecting all the elements. According to the system, switching of multiple heat management modes can be achieved according to the external environment and the working condition of the electric vehicle, the working condition coverage range is wide, the applicability is high, the heat management requirements of a passenger compartment and a battery pack of the whole vehicle under different working conditions can be met, the system efficiency is improved, and thepower consumption is reduced.

Description

technical field [0001] The invention relates to the technical field of automobile thermal management, in particular to an integrated heat pump management system for a pure electric vehicle and a pure electric vehicle. Background technique [0002] Traditional fuel vehicles consume a large amount of oil resources, and at the same time, the exhaust gas will cause serious pollution to the environment. Under the dual pressure of energy shortage and environmental protection, electric vehicles, due to their advantages in environmental protection and sustainable development, It has received more and more attention and policy support from the society. Major traditional car companies and new Internet car manufacturers have begun to lay out the electric vehicle industry. At the same time, the development of the Internet industry has further promoted the intelligentization and electrification of automobiles. [0003] With the rapid development of electric vehicles, their battery life,...

Problems solved by technology

[0005] At present, due to technical cost and other reasons, many electric vehicle manufacturers mostly use PTC electric heating to heat the cabin, but because the energy efficiency ratio of PTC electric heating is always less than 1, it needs to consume a lot of electric energy, and some models use PTC electric heating in winter. Can be attenuated by 30% to 50%, seriously affecting user experience
