【Abstract】 This paper discusses the importance of electrical durability test of automotive apparatus,and points out the defect of the traditional test method which can’t reflect the real working condition.The paper analyzes various factors that affect the electrical durability of automotive apparatus and point out that the electric characteristic is the decisive one.The paper works out the electric current characteristic curve and math equation of the automotive apparatus when it works.Four parameters of the electric current characteristic are summed up,they are peak value,steady value,time of peak value,and the width of the wave peak,and the four parameters have widespread significance.A feasible project of a new type test device is presented.更多还原
