Abstract: Parking air conditioner is a new type of automotive electrical appliance that has emerged in recent years, it is widely used in the front and rear installation of heavy-duty trucks due to its high energy efficiency, long endurance, and comfort. With the deepening use of parking air conditioner by drivers, the installation of fuel generators to increase the driving time of parking air conditioner is becoming more and more common, resulting in an increasing number of electrical failures. Based on ISO 7637-2 standard of surge failure evaluation, the failure research is carried out in this paper. By improving the standard experimental methods and optimized circuit design, the problem can be solved. A new evaluation method is established, and it is clear that surge reliability design should adopt different circuit design in different systems.
