The invention provides an air conditioner and heater integrated system, an integrated system control method and an electric vehicle, and relates to the technical field of electric vehicles. The systemcomprises an electric air conditioner, a heater and a relay, the first end of the relay is electrically connected with a neutral point of an electric air conditioner compressor in the electric air conditioner; the second end of the relay is electrically connected with the heater; the electric air conditioner is in signal connection with the control unit; when the control unit controls the electric air conditioner compressor to work, the relay is switched off, and the heater does not work; and when the control unit controls the electric air conditioner compressor not to work, the relay is closed, and direct-current voltage is generated on the neutral point of the electric air conditioner compressor, so that the heater works. According to the system, few components are used, the control mode is simple, a circuit line is very concise, the space occupied by the whole system is greatly reduced, and the cost of the electric automobile is indirectly reduced.

    本发明提供了一种空调与加热器集成的系统、集成系统控制的方法及电动汽车,涉及电动车技术领域,所述系统包括:电动空调、加热器以及继电器;继电器的第一端与所述电动空调中电动空调压缩机的中性点电连接;继电器的第二端与所述加热器电连接;电动空调与控制单元信号连接;控制单元控制所述电动空调压缩机工作时,所述继电器断开,所述加热器不工作;控制单元控制所述电动空调压缩机不工作时,所述继电器闭合,所述电动空调压缩机的中性点上产生直流电压,使得所述加热器工作。本发明系统使用的元器件很少且控制方式简单,电路线路十分简洁,极大的减少了整个系统所需占用的空间,间接降低了电动汽车的成本。
