In modern society, energy saving issues of industrial vehicles are very important for both economically and environmentally. Energy savings using the potential energy of forklifts must be one of the very good solutions. The basic concept is to run the generator using the flow rate discharged from the cylinder when the fork down while carrying a heavy object, and recharge the battery. This study aims to control the flow rate through the use of variable motor to achieve higher energy savings. Using AMEsim, compare the model with the fixed motor and the model with the variable motor and analyze it through the efficiency map to suggest a strategy with better energy efficiency.

With the recent emergence of fossil fuel depletion and environmental pollution issues internationally, the construction and industrial heavy equipment sectors are required to develop technologies to reduce emissions and energy consumption. Currently, research on energy saving in construction machinery is being actively carried out to solve these problems, and hybrid systems, including energy recovery, are one of the most popular energy solutions. This study proposes a combined hybrid hydraulic system, including power distribution devices, and various operating modes to increase energy efficiency. And also builds simulation models through Amesim-Simulink Cosimulation. Afterwards, the control strategy is established using fuzzy control and optimized using genetic algorithms to maximize the energy efficiency of the system. The proposed system and control strategy are verified by experiment.
