This paper studies the multi-objective energy management strategy for hybrid energy storage systems in electric construction machinery. Through in-depth analysis of the operating characteristics and energy requirements of electric construction machinery, a multi-objective energy management method capable of optimizing the performance of energy storage systems is proposed. By reasonably allocating energy between batteries and supercapacitors, this strategy achieves efficient energy utilization and extends the service life of equipment. Considering the dynamic changes in load demands and working environments, a scheme for flexibly adjusting the energy management strategy is put forward. The application of this multi-objective energy management strategy can effectively improve the operational efficiency and reliability of electric construction machinery.
