Embodiment Construction

[0018] The present invention will be described in detail below according to the accompanying drawings, which is a preferred embodiment among various implementations of the present invention.

[0019] An air-conditioning system for an extended-range electric vehicle. Further, it will adopt a traditional mechanical air-conditioning compressor 4, and an electromagnetic clutch is used between the air-conditioning compressor 4 and the air-conditioning compressor pulley 5.

[0020] When there is no air conditioner work request, the clutch is disconnected. When the generator 4 was working, only the air conditioner compressor belt pulley 5 was idling without load. When there is an air conditioning work request, the clutch is connected. The air-conditioning system has two working modes, electric mode: when the whole vehicle is running in pure electric mode, the motor controller 9 controls the generator 3 to work as a motor after receiving the air-conditioning work request signal, driv...

Abstract

The invention relates to an air-conditioning system of an extended-range type electric vehicle and a control method thereof. The air-conditioning system is used for the extended-range type electric vehicle and comprises an engine, a power generator, an air-conditioning compressor and an air-conditioning compressor belt wheel, wherein the engine is connected with the power generator and can drive the power generator to operate; the engine is connected with a power generator belt wheel and can drive the power generator belt wheel to operate; the power generator belt wheel is connected with a belt and can drive the belt to operate; the air-conditioning compressor is provided with the air-conditioning compressor belt wheel; and the belt is connected with the air-conditioning compressor belt wheel and an air-conditioning system and is used for driving the air-conditioning compressor belt wheel to rotate and driving the air-conditioning system to operate.

Description

technical field [0001] The invention relates to the technical field of pure electric vehicles, and relates to an air-conditioning system of an extended-range electric vehicle. Through multiplexing of power devices and switching of working modes, the system can save costs and increase the conversion efficiency of the system. Specifically, it relates to an extended-range electric vehicle. Vehicle air conditioning system and control method thereof. Background technique [0002] With the advancement of science and technology, the increasing scarcity of oil resources and the improvement of public awareness of environmental protection, electric vehicles have attracted more and more attention. Some electric vehicles now use a mileage booster to increase their cruising range. The mileage booster is generally composed of a low-power gasoline engine and a generator connected to the engine. After the power battery is exhausted, the generator can be driven by the car engine as power. B...
