Braking Energy Recovery System Design

Nowadays, the energy consumption and environmental pollution pressure cars bring has become a global challenge. In order to ease the pressure of energy and environment, the loss energy during automobiles braking can be regenerated and reused when the automobile starts or accelerates. By this way, not only benefit the environment, but also prolong the life of vehicle's braking parts. At present, there are four kinds of energy storage devices on the research, flywheel storage, hydraulic energy storage, electrochemical energy storage, and pressure storage. This paper makes a simple analysis of these four ways, and design a regenerative braking system based on the flywheel storage devices.
