“…In recent years, literatures reported that filament winding technology was used to manufacture the shell of accumulator in order to reduce the shell weight and improve the power density greatly, the shell weight used new technology was only half or even 10% of that in traditional hydraulic accumulator, however, this accumulator has not reached the stage of project application yet [31]. Peter Achten mentioned the opinion of combining the battery having the advantage of high energy density with hydraulic accumulator in hybrid power vehicles in literature [32]. Fig.…”

This paper describes the basic components and characteristics of the hydraulic secondary regulation system based on the CPR(Common Pressure Rail), then primarily focuses on the application of the CPR in various industries combined with the advantages of the CPR which can recover energy and drive several loads independently rather than great interference with each other. Also the paper analyses the key technologies of the CPR including the exposition in the development process of the hydraulic transformer, the analysis in energy-saving components and constant pressure control of pumping station in the CPR, and then looks forward to the development prospects of the CPR.

The configuration and working principle of hydraulic hybrid vehicle (HHV) based on the hydraulic transformer (HT) were described to extend its energy-regenerated potential. The approximate algorithm of basic elements for pipeline distributed parameter model was summarized to simplify the pipeline model calculation, and the various basic elements of this method were proven to be used in the practical application by comparison with the experimentally validated Zhao and Hullender model. The pressure pulsation characteristics between the HT and accumulator of the HHV by considering Zhao model, Hullender model, and original pipeline approximate model was analyzed to optimize the system structure design by the method of the mathematical model, which mainly includes the series accumulator and parallel accumulator, respectively. The simulation result shows that the series accumulator was better than the parallel accumulator in terms of pulsation damping of hydraulic transformer with considering the pipeline effect. The test-rig result shows that the theoretical analysis of the pulsation between the HT and accumulator with pipeline was very close to the measurement data of the experiment in the curve trend, where the theoretical analysis results of pulsation characteristic for HHV were appropriate and reasonable.

Abstract. The charging process is one of the critical processes in the hydro-pneumatic driveline storage system. It converts the kinetic energy of the vehicle braking and coasting to the compression energy. This energy is stored in the storage device called the accumulator. The system is planned to be used on the dual hydro-pneumatic hybrid driveline and applied to a hydraulic hybrid passenger car. The aim of this paper is to find the effect of charging parameters on the storage performance through simulation. Through the storage behaviour, the desirable and optimal sizing of the accumulator can be selected. The paper emphasized on the effect of pressure elevation, pre-charge pressure, effective volume, thermal reaction and required time of the accumulator's charging process. The circuit of charging process has been designed and simulated by using the hydraulic tool in the Automation Studio software. The simulation results were corroborated through the component specification for data rationality. Through the simulation, it was found that pre-charge pressure had a significant effect on the charging process. It determined the efficiency of the effective volume. The higher the pressure elevation, the higher the effective volume. Nevertheless, the more energy required to compress the nitrogen gas in the bladder. Besides, in term of volume displacement, higher volume displacement reduced charging time and lower the fluid temperature. The simulation had been positively highlighted the critical point in charging process which later on, benefited the sizing process in the component selection specification.
