Air conditioning domain control system for pure electric vehicle

Abstract

The invention discloses an air conditioner domain control system for a pure electric vehicle. The system comprises an insulated gate bipolar transistor module, an isolation drive module, a high-voltage current measurement module, a power distribution management module, a digital signal control module, a CAN network module, an LIN network module, an analog signal input module, a single-chip microcomputer module, an air conditioner panel input module, a drive module and a processing module. One end of the insulated gate bipolar transistor module is connected with one end of the isolation drive module and one end of the high-voltage current measurement module. The other end of the isolation drive module and the other end of the high-voltage current measurement module are connected with the single-chip microcomputer module. One end of the power distribution management module, one end of the digital signal control module, one end of the CAN network module, one end of the LIN network moduleand one end of the analog signal input module are connected with one end of the single-chip microcomputer module. The other end of the single-chip microcomputer module is connected with one end of theair conditioner panel input module, one end of the drive module and one end of the processing module.

Description

technical field [0001] The invention relates to the technical field of electric vehicles, in particular to an air conditioning domain control system for pure electric vehicles. Background technique [0002] Compared with conventional vehicles, that is, fuel vehicles, electric vehicles replace the power system of conventional vehicle fuel engines with power sources, resulting in the use of compressors for engine-driven air-conditioning systems on conventional models and heating through engine cooling systems. Wind systems can no longer be used on electric vehicles. In the electric vehicle, the power source is the power supply, so the compressor in the air conditioning system is replaced with an electric compressor, and the water heater in the heating system is replaced by an electric heater PTC. Since the electric compressor and electric heater of the electric air conditioning system consume electric energy of the electric vehicle, if the electric energy consumption of the a...
