Abstract

Electric forklifts are becoming widely used for material handling and short distance transportation. Traditional electric forklifts use lead-acid battery packs as the power source, and the hydraulic system has no energy recovery function. a large amount of recyclable potential energy is wasted in the form of overflow loss and heat generation, resulting in low system efficiency. The paper establishes an energy recovery experiment system for heavy electric forklifts with a combination of hydraulic motor and permanent magnet synchronous motor, using lithium iron phosphate batteries for energy storage. The dynamic process of generating current during the energy recovery process is studied. The experimental is shown that the generating current increases with the increase of load and the system becomes more stable.
