摘要

In this study, we developed a hybrid power source with a direct current (DC) supply system for electricforklifts. Its designs were based on harsh operating conditions, in line with the requirements for thetruck. The power source consists of a fuel cell (FC) system, lithium ion batteries, and supercapacitormodules. This system supplies the pallet truck with the power needed for lifting and moving. In theexperiments, three kinds of power source modules were designed, and their performance was testedindividually. The modules were then combined and tested using machines to simulate load conditions.The test parameters examined were the rate of the supercapacitor and charging and dischargingproperties. A final simulation of the overall power output performance was also performed. The poweroutput may be divided into power for lifting and power for moving. The FC is the power source for thetraveling motor, while the lithium ion battery is the supply for maximum instantaneous power for thepallet truck. The super capacitors protect the FC and batteries and ensure high power output. It can alsooffset the insufficiency and instability of the power provided by the first two power sources andprovides a stable 24 V DC power supply for the traveling motor when connected to a DC powerconverter. The lithium ion battery and supercapacitor modules are able to power the lifting motors,which require high power output, providing a maximum instantaneous power of 3.2 kW for severalcycles of lifting. The power source proposed here therefore has potential use in hybrid systems.
