要約(英語): The regenerative braking for electric vehicles is studied. The experimental device consisted of rotational load, three-phase synchronous motor, regenerative circuit and Electric Double Layer Capacitors (EDLC) as the energy storage is modeled and analyzed. Rotational kinetic energy of rotational load is converted into electric energy by regenerative motor. EDLC is charged by kinetic energy through regenerative circuit consist of switching circuit and booster circuit. In order to slow down vehicle so that drivers and passengers do not feel uneasy, the deceleration and jerk should be reduced. Therefore, deceleration is controlled by changing current value of main circuit by regenerative circuit in order to decelerate at the target deceleration when regenerative brake is applied. In addition, a regenerative braking system with high versatility and trackability to target deceleration is investigated by using PI control for regenerative circuit control, which is previously set based on the results of analysis. As a result, deceleration control in line with the target value is achieved from the start of deceleration to just before stopping. The regenerative efficiency is 11.3% and about 3% larger than the conventional system. Moreover, when the initial velocity is tripled, the regenerative efficiency is 12.3%.
