Abstract: This paper proposes a novel potential energy regeneration system (PERS) using a hydraulic accumulator and a valve–motor–generator for a hybrid hydraulic excavator (HHE). To analyze the dynamic performance of the proposed PERS, mathematical models are established. A numerical analysis is conducted to guide the parameters design of the key components in the PERS. The control strategy for the energy regeneration system (ERS) is discussed. Simulations are carried out in AMESim to validate the effectiveness of the novel PERS. The results demonstrate that the dynamic performance of the PERS is close to that of a throttle-governing system. The efficiency of the PERS is about 58%.
