Selection And Simulation Research Of Fuel Cell Electric Vehicle's Drive System

With the car production and existent volume growing, emission gas by the vehicle, which the power bases on oil product, has become a major source of environmental pollution and urban pollution, in addition, the energy shortage has become increasingly grim. To this end, the developed countries of the world have a new type of strategic eyes on the development and use of clean energy. For the fuel cell technology is increasingly mature, particularly proton exchange membrane fuel cell (PEMFC) as a new, clean, efficient and environment-friendly energy, has attracted the world automobile industry.The fuel cell electric vehicle (FCEV) takes the fuel cell as the power source, and it directly converts the fuel chemical energy into the electrical energy, and actuates the electromotor to drive the vehicles. It overcomes the blemish of pure electric vehicle, which uses battery as the power supply and has a short continued driving mileage. It also overcomes the blemish of hybrid electric vehicle , which uses the internal combustion engine and the battery as the power supply and has exhaust pollution. Compared with the traditional internal combustion engine vehicle, FCEV does not have the conversion of the heat engine process and the Garnot cycle limit, and has a high energy efficiency, the environment friendly and so on the internal combustion engine vehicle incomparable merit, at the same time still might maintain the performance of the traditional internal combustion engine vehicle, such as the high velocity, continued driving mileage and the security, comfortable. FCEV is first choice as the clean highly effective transport means in the 21st century. In general, fuel cell electric vehicle also may divide into the pure fuel cell electric vehicle and the fuel cell hybrid power vehicle (electricity —electricity hybrid), this article studies the fuel cell hybrid power vehicle.This article takes the ADVISOR software as the simulation platform and makes the brief introduction to each major component model and the principle of fuel cell electric vehicle drive system in the ADVISOR.The selecting and matching of the fuel cell electric vehicle's drive system is very important for the vehicle's research and development. This article selects the fuel cell electric vehicle for the one man driving as an example. According to dynamic acquireand range, this article chooses each major component (motor, fuel cell, battery unit) of the system and defers to two ways, which takes the fuel cell primarily power supply, the battery unit as the auxiliary power supply and takes the battery unit primarily power supply, the fuel cell as auxiliary power supply, and carries on the parameter match. This article uses ADVISOR to carry on dynamic, the fuel economy simulation research, compared with the simulation result, determines a more reasonable match way. In the foundation of this match way, studied mixed properly to the equivalent fuel oil efficiency influence. This article has also studied the vehicles energy efficient influence, which include the fuel cell transfer efficiency, the vehicles lumpy mass, the air resistance coefficient, the rolling resistance coefficient.
