Abstract

Abstract: PTC electric heating is widely used in the air conditioning system of electric vehicles. This paper studied the PTC electric heater detection bench. First, introduced the research background and three keys of the detection bench control system: PWM board, serial port protocol, design of database. Then, elaborated the three key points respectively, including board structure, analysis of serial port protocol and design ideas of database. Finally, the detection bench was set up and tested repeatedly. The results of experiment shows that the bench achieved expected goals.
