A boom potential energy recovery scheme for hybrid excavator is proposed, which is based on hydraulic accumulator and power battery. The multi-objective optimization method is used to match the parameters of key components of the energy recovery system. Furthermore, for the recovery system, a simulation model and control strategies are established to analyze the effect of parameter matching and control methods by simulation. Finally, a hybrid excavator test platform of boom potential recovery system is built up to study the recovery effect and handling performance. Experiment results show that not only the recovery program is feasible but also the system operation performance is stable, the parameter matching effect is good and energy recovery rate is high.
