Embodiment Construction

[0042] In order to make the technical solutions and advantages of the present application clearer, the implementation manners of the present application will be further described in detail below in conjunction with the accompanying drawings.

[0043] Electric vehicles are driven by electric energy, and will not produce exhaust gas to pollute the environment during use, which is the key to achieving "carbon peak" and "carbon neutrality". The thermal efficiency of traditional fuel vehicle engines is low, and the heat generated by the engine can meet the heating needs of the passenger compartment of the vehicle; while the thermal efficiency of electric vehicle motors is as high as about 90%, and the heat generated by the motor, inverter and reducer is small, and this part of heat cannot be used in winter To meet the heating needs of the passenger compartment, an additional heating structure is required.

[0044] At present, there are two heating schemes for electric vehicles in w...

Abstract

The invention discloses an electric automobile heat pump system, and belongs to the technical field of electric automobile air conditioners. The system comprises a waste heat storage loop, a heat pump loop and a first waste heat utilization loop. A motor, an inverter and a heat accumulator are sequentially arranged on the waste heat storage loop, and a circulating medium in the waste heat storage loop is cooling liquid; a compressor, a first condenser, a first electronic expansion valve and a first heat exchanger are sequentially arranged on the heat pump loop, and a circulating medium in the heat pump loop is a refrigerant; the heat accumulator and the first heat exchanger are arranged on the first waste heat utilization loop, and a circulating medium in the first waste heat utilization loop is cooling liquid. The heat pump system of the electric vehicle makes full use of waste heat of heat production components such as the motor, and the cruising ability of the electric vehicle is effectively improved.

Description

technical field [0001] The present application relates to the technical field of electric vehicle air conditioners, in particular to an electric vehicle heat pump system and an electric vehicle. Background technique [0002] With the concept of green environmental protection gradually becoming popular, electric vehicles have gradually become the new darling of the automotive industry. Here, an electric vehicle refers to a vehicle that is powered by an on-board power supply and uses a motor to drive the wheels. [0003] At present, when the car is used in winter, electric vehicles usually use thermistor heating to heat the passenger compartment to ensure the comfort of the driving environment for the drivers and passengers. However, this heating method consumes a large amount of electric energy, which affects the cruising range of electric vehicles. Contents of the invention [0004] In view of this, the present application provides an electric vehicle heat pump system an...
