Regenerative braking systems use vehicle's kinetic energy to generate and store electrical energy in battery storage. However, the principal shortcoming of a regenerative braking system is the capability to store the entire re-generated electric power in the battery storage in short time. Therefore, only a small portion of the vehicleâs kinetic energy can be recaptured and stored. Hence, alternative techniques are required to increase the amount of recaptured power. One possibility is the usage of a high-pressure hydraulic system. Various configurations of hydraulic energy storage in hydraulic propulsion system have been investigated Hewko et al. These storage systems can be classified as pure hydrostatic, hydro-mechanical and power assist systems.
