The Research of End of Line Test System in Electric Vehicles Based on CAN Bus

Abstract

With the mass production of Electric Vehicles, end of line test of Electric Vehiles has become an important research topic.In this paper, a scheme of the system with a portable computer is establish for thepractical application to the end of line test based on CAN bus, and then design and research of the testing system software are followed. To develop establish the system scheme, we study in depth and explore test methods and management, and design two test modes in view of the practicality and re-usability of the test system. In the process of system software development, we program in LabVIEW, manage the test items in NI TestStand, make a research and optimization of Microsoft Office Access database connection for both software, and design user interface program of database maintenance and management finally. Commissioning not only verifies practical performance of the test system in the aspects of testing, data processing and others, but also feedbacks the reference information to enhance and improve the stability and re-usability of the system based on CAN bus.
