Power Distribution Design of Passenger Vehicle

Abstract

The chapter discussed the method of power distribution of passenger vehicle, and indicated the key points of power distribution. Via analyzing the property of electronic and electrical parts in vehicle, we ascertain the load characteristics of electronic and electrical parts, define the load types of different electronic and electrical parts, define the application strategy of fuses and the original power distribution draft. According to the numbers and power of load, calculate the capability of fuse and choose the type of fuse. Then, via the capability of fuse, calculate the diameter of wire connecting with the fuse. Finally, summarize all the information to design the particular power distribution drawing. The process method and key points of power distribution discussed in the chapter are based on an economical car of FAW R&D Center, and the design result is validated by the economical car. The chapter mainly discussed common fuse and wire diameter selection, did not contain some special fuse such as main fuse selection principle or contain the layout and number of fuse. Nowadays, there’re few articles about the power distribution study. However, this chapter discussed the power distribution systematically in order to assist the design of power distribution and guide the engineering design of power distribution of passenger vehicle. Power distribution is the key point of electrical system design. The chapter discussed the process, method and key points of power distribution. It is verified by an Economic car. This chapter discussed the power distribution in order to assist the design of power distribution and be helpful of the engineering design of power distribution about passenger vehicle.
