Study On Auxiliary Power Electric Vehicle Match And Motor Control System

Vehicle industry is mainstay of national economy. The automotive popularization is the concrete performance of people's life level. But with increase number of automotive made energy exhausted and environment pollution. The same as world vehicle industry. In order to save rare oil resource, reduce oil consume and decrease exhaust pollution, ensure provide oil to industry unit which must take oil as stuff, seek substitute energy is a new vehicle development direction. Electric vehicle(EV) is being main choice. It has long distance in pure electric vehicle market for unripe storage battery's technical. So it is important for empolder auxiliary power EV. The first chapter introduce the status quo of inside and outside national vehicle development. Then put forward one project about auxiliary power EV (â…¡ type EV) base on "GDQW-1" (â…  type EV ) electric vehicle. Chapter 2 explain the concept of auxiliary power, elaborate APEV in the basic structure, whole vehicle control system constitute and principle and APU aspects. Finally to statement how to choose the type of the APEV's key components. Chapter 3 statements the whole structure of APEV's motor control system and working principle. Fulfill the design and realization of control system's software and hardware. Elaborate the circuit principle which belongs to the low power subsystem and high power subsystem of control system's hardware. It adopt modularization idea to design control system's software. Guaranteeding expansibility, transplant inherited of software. Chapter 4 statements about progressing battery experiment, motor experiment, engine experiment, charge and discharge data adoption and display system aspects respectively base on the trial plat of APEV. The trial results prove this motor control system run reliably. APU take on effect in control system. The last chapter summarizes whole paper and points out further research aspects. Improve reliability in some respects through ameliorate â…  type EV's motor control system. It is gain optimal economical capacity and prolong EV driver distance simultaneity. And help to prolong the battery's life. Compare with â…  type EV, improve EV once charge drive distance after added APU.
