Hydraulic storage systems generally use pneumatic means such as a nitrogen bladder as the actual storage medium with the hydraulics as the actuation system. A taxomomy of energy storage systems has been done that shows the relative energy density of the various media. Table 10.1 is a summary of these fundamental energy storage systems.
To get the maximum benefit of the high power density of hydraulic and pneumatic energy storage, Bravo R R S et al. explored a new configuration of hydraulic–pneumatic recovery configuration for heavy vehicles to store braking energy used for propulsion or auxiliary systems, as illustrated in Figure 14. Figure 14.
To understand the diagrams the two contrary effects of adding a hydraulic storage system to the car have to be considered: On the one hand the storage allows to recuperate otherwise wasted energy, on the other hand the resulting higher mass of the vehicle leads to higher rolling friction losses.
Mechanical storage systems include flywheels, plus pneumatic (hydraulic) and elastic mediums to store energy in its kinetic and potential energy forms, respectively. Hydraulic storage systems generally use pneumatic means such as a nitrogen bladder as the actual storage medium with the hydraulics as the actuation system.
Hydraulic energy recovery systems have been investigated by researchers for a while. Panchal et al. modeled a system consisting of a hydraulic pump, a hydraulic accumulator and a hydraulic motor . From their model, they found the charging efficiency of the system to be around 83% and the discharging efficiency to be 87%.
