Forklift Fuel Cell Drive System Modeling And Simulation

With the continuous development of the logistics industry, logistics major mechanical forklift vehicles that social production, and demand will keep growing. However, the ownership of oil continues to decrease, prices are up year after year, internal combustion forklift has very serious air pollution. The development of internal combustion forklifts continue to suffer the inevitable blow, thereby affecting the logistics industry. Fuel cell technology as an efficient, clean and high quality power source, has attracted world wide attention to the logistics industry.Fuel cell hybrid trucks, to fuel cells as the main power source, it will be the chemical reaction of hydrogen and oxygen chemical energy directly into electricity, through the drive motor driver forklift job. It overcomes the problem of emissions from internal combustion forklift batteries as a power source as well as electric forklift continued to make short-distance disadvantage. Compared with the conventional internal combustion forklifts, fuel cell hybrid forklift does not heat the process, the restrictions are not subject to Carnot cycle, with high combustion efficiency, no emissions and no waste disposal, and no work noise characteristics. While also maintaining the traditional internal combustion forklift performance. Compared with electric forklifts, no need to spend a few hours to charge the battery, only takes a few minutes to fill the storage of compressed hydrogen gas can be a great energy.Articles on several fuel-cell electric vehicles to analyze the basic structure, to define a fuel cell system, the basic structure of electric forklift driver, and the selected drive mode. Described in detail the internal structure of the fuel cell and its sub-working mechanism. Energy control strategy in the vehicle switches to control and compared the advantages and disadvantages of the power tracking control, according to the actual need for the power control strategy as the following article forklift control system. ADVISOR software simulation platform in the establishment of truck drive system simulation model. ADVISOR software for hybrid fuel cell forklift drive system model of the major parts of the structure and working principle is briefly introduced.Forklift fuel cell hybrid drive system parameters match the fuel cell hybrid trucks on the main job. According to the car's dynamic performance, the drive system on the truck all the major components (fuel cell, battery, motor) for selection. Through the various fuel cell drive system of the comparative analysis of the FC+B is established fuel cell hybrid drive system mechanical forklift, the use of ADVISOR for power, fuel economy simulation study to compare the simulation results to determine a reasonable matching results.
