Experimental Study on Energy Consumption Distribution of Electric Forklift

Abstract

In this paper, the energy consumption and its distribution of forklift in various working conditions are analyzed through experiments, and the main factors of energy consumption are found, which can find a breakthrough for system energy saving and provide theoretical basis for subsequent research. According to the measured battery output voltage and current of the electric forklift, the walking system accounts for about 42.7% of the overall energy consumption of the hydraulic system, the steering system accounts for about 13% of the overall energy consumption of the hydraulic system, the pitch system accounts for about 0.3% of the overall energy consumption of the hydraulic system, and the lifting system accounts for the largest proportion of the overall energy consumption of the hydraulic system, reaching about 44%.
