Electric car manual air conditioning system and control method thereof

Abstract

The purpose of the present invention is to propose a manual air-conditioning system for electric vehicles and its control method, so that the traditional manual air-conditioning can meet the needs of customers for cooling comfort without major changes, and can also effectively save the cost of the entire vehicle. Electric energy consumption, thereby prolonging the cruising range of electric vehicles. The electric vehicle manual air-conditioning system of the present invention includes an air-conditioning body and a control system. The air-conditioning body includes a compressor, an evaporator, and a control panel. The key point is that the control system is composed of an outside temperature sensor, a vehicle speed sensor, and a control unit. The control unit is respectively connected with the outside temperature sensor, vehicle speed sensor, evaporator surface temperature sensor and compressor. The key to the control method is: during the working process of the compressor, the control unit controls the speed of the compressor according to the outside temperature and the vehicle speed. The specific control principle is as follows: the higher the outside temperature, the higher the compressor speed; the higher the vehicle speed, the higher the speed of the compressor. The lower the compressor speed is.

Description

technical field [0001] The invention relates to the field of new energy vehicles, in particular to an electric vehicle manual air conditioning system and a control method thereof. Background technique [0002] With the continuous improvement of the economic level, the residents' demand for convenient travel is becoming stronger and stronger. As the most important means of transportation in the transportation field, the demand for automobiles is increasing day by day. With the increase in the number of automobiles, global energy and environmental issues have become increasingly prominent. Emissions have become the focus of attention in the world. In order to promote energy conservation and emission reduction, all countries are vigorously developing new energy vehicles represented by electric vehicles. However, the battery capacity of electric vehicles is limited, and the cruising range is directly limited by the capacity of the battery and the power consumption of related equ...

Problems solved by technology

[0003] The air conditioner is an important part of the car to improve the comfort of passengers, and it is also an energy-consuming part of the car. The compressor control of the traditional manual air conditioner is relatively simple, and the speed cannot be adjusted. It can only cool at a constant speed, or stop when the protection is triggered. Turning, that is, it gives priority to meeting the customer's cooling needs. As long as it is turned on, it will consume the electric power of the entire vehicle battery. There is no concept of energy saving at all, but the price is relatively cheaper
