Abstract: This paper focuses on the design and development of multi-functional vehicle electrical test bench. In view of the defects of single function and poor expansibility of the existing automotive electrical test bench, an innovative design scheme with multi-function, modularity and high integration is proposed. This scheme focuses on the design and development of multifunctional automotive electrical test bench, integrates advanced control technology, builds flexible hardware architecture, and configs customizable software system, so as to detect and simulate automotive electrical system in an all-round way. In the process of design and development, it focuses on the simulation of the response and protection mechanism of automotive electrical appliances under various overload conditions. With the carefully built platform structure and control system, the overload state of automotive electrical appliances can be accurately simulated and monitored in real time. In this paper, not only the function characteristics of the experimental bench are detailed, but also the use method and application scenario are clearly described. The successful research and development of this experimental bench plays a vital role in enhancing the research and development efficiency of automotive electrical systems, reducing research and development costs and optimizing product quality, and provides valuable reference experience for related fields.
