As excavators increasingly incorporate advanced technologies, integrating flywheel energy storage systems can further enhance overall efficiency, reduce fuel consumption, and enable smoother operation across diverse job sites.
The regeneration system always requires at least one energy storage device. However, using a single storage device is difficult to meet the need for energy recuperation as well as performance satisfaction of excavators. Some researches combine two independent energy storage devices to form a combined energy storage system.
First, potential recoverable energy sources in excavator mechanisms are analyzed. Next, energy regeneration systems are classified according to energy storage devices and their development is comprehensively reviewed through the state-of-art.
To verify the effectiveness of this system, a real test bench based on a 6-ton hydraulic excavator was performed. The experimental results showed that 50.1% energy consumption of the boom and 64.9% peak power of the power source can be reduced in the proposed system compared with the double-chamber system.
Based on these insights, a novel energy regeneration system for the swing drive of the hydraulic excavators is proposed. This system integrates an automatic switch control system, designed to optimize energy savings and enhance regeneration efficiency, along with an intelligent brake control system for precise tracking of the swivel angle.
This paper proposed a novel energy management strategy for a PEM fuel cell excavator with a supercapacitor/battery hybrid power source. The fuel cell is the main power supply for most of the excavator workload while the battery/supercapacitor is the energy storage device, which supplies additional required power and recovers energy.
The results showed that the proposed system could recover and reuse about 82.7% of the potential energy. Compared with an IMV system, the power consumption during the lifting process could be decreased by 76.1%. Moreover, during the entire working cycle, reduced energy consumption could be reached by 75.0%.
