Abstract

The invention discloses an air-conditioning control system of an electromobile. The control system comprises an air-conditioning compressor, a blower assembly, a transmission controller and a storage battery, and is characterized in that a heating circuit comprises a heating switch, a direct current contactor and a heating element, wherein the heating switch is controlled by a cold-hot air rotary switch; the heating switch, the coil of the direct current contactor and a fan switch are connected in series and then are connected between a power supply and an earth wire; and the heating element and a normally open point of the direct current contactor are connected in series and then are connected to two ends of the storage battery. According to the invention, the match and combination of a special compression system of the electromobile and an original air-conditioning system of a common automobile are completed, and the control on an air-conditioning refrigeration system is finished effectively; simultaneously a PTC (positive temperature coefficient) heating body is adopted, and the perfect refrigeration and heating functions are realized; the control system is used for a pure electromobile which is obtained by modifying the common automobile, the design of a circuit is simplified greatly, the control system is convenient to install and use, and the modification efficiency of the electromobile can be improved greatly; and the control system has the characteristics of simple structure, low cost, safety and reliability, and is convenient to use and install.

Description

technical field [0001] The present invention relates to an air-conditioning control system of an electric vehicle, and more specifically relates to an air-conditioning control system of an electric vehicle which refits an engine vehicle into an electric vehicle and fully utilizes the air-conditioning system of the original vehicle. Background technique [0002] Electric vehicles have the characteristics of no pollution, low noise, high energy utilization rate and a wide range of energy sources. The development of mature electric vehicle technology is conducive to the realization of the country's sustainable development strategy. In the process of converting engine vehicles (hereinafter referred to as ordinary vehicles) into pure electric vehicles, due to the poor manufacturing technology of the vehicle chassis of many companies at present, in order to ensure the quality and reliability of the vehicle chassis, a large number of finished ordinary vehicles are used Conversion t...
