Air conditioner control method for electric vehicle and electric vehicle

Abstract

The invention provides a method for controlling the air conditioner of an electric vehicle and the electric vehicle. The air conditioner includes a compressor, a defrosting fan and a defrosting heater. The electric vehicle includes a front windshield, and a humidity detection device is arranged on the front windshield. The control method includes a compressor control method and a defrosting control method; wherein, the compressor control method includes: according to the relationship between the interior temperature T1 of the electric vehicle and the set temperature T2 of the air conditioner or the external temperature T3 of the electric vehicle, And the remaining power of the electric vehicle controls the work of the compressor; wherein, the control method of defrosting includes: controlling the work of the defrosting fan and the defrosting heater according to the humidity value of the front windshield detected by the humidity detection device, so as to control the operation of the defrosting heater for the electric vehicle The remaining power is allocated reasonably to prevent a large amount of power from being used by the compressor and defrosting heater of the electric vehicle during the operation of the electric vehicle, so as to improve the energy efficiency of the electric vehicle and extend the cruising range.

Description

technical field [0001] The invention relates to the field of electric vehicles, in particular to an electric vehicle air conditioner control method and the electric vehicle. Background technique [0002] With the depletion of traditional energy sources, pure electric vehicles have become an indispensable branch of the automotive industry. The use of pure electric vehicles can not only save energy, but also reduce exhaust emissions, reduce PM2.5 emissions, and protect the environment. And as the electric energy reserves of electric vehicle batteries continue to increase, the battery life of electric vehicles continues to increase, which has become the first choice for more and more users when purchasing a car. [0003] The existing on-board air conditioners of pure electric vehicles include compressors, defrosting fans and defrosting heaters, etc., which are used to improve the comfort of users in the car. These devices are generally controlled by the electronic control syste...

AI Technical Summary

Problems solved by technology

[0004] In view of this, one of the objects of the present invention is to provide a method for controlling the air conditioner of an electric vehicle and the electric vehicle, to solve the problem that the air conditioner of the electric vehicle and the vehicle control system of the electric vehicle in the prior art are independent of each other. , resulting in the high power consumption of the air conditioner of the electric vehicle, which cannot reasonably distribute the electric energy, let alone achieve the optimal matching between the comfort and the cruising range
