Standardized automotive load dump testing

Abstract

The intent of this study is to depict the load dump phenomenon in the electrical system of an automobile. The factors that determine the severity of the pulse and their effect on the variety of electronic components found in the cars of today are discussed. A detailed review of the existing load dump standards including pulse parameters, test methods and required equipment are included along with recommended amendments. This study clarifies the misconceptions that have arisen in the recent past, and addresses the problems associated with the simulation of a load dump. Once these misunderstandings are resolved and the inherent problems understood, a clear definition of the load dump simulation and methodology is conceived.<>
