dsPIC를 이용한 전기자전거의 속도에 따른 회생제동에 관한 연구

Due to the environmental pollution and exhausted resources, these days, a research is in progress to find renewable energy which will substitute or reduce using of fossil energy. To correspond with HEV has been developing actively. Regenerative braking is widely applied for fuel efficiency improvement, stability of vehicle and reducing energy in HEV. This paper demonstrate the superiority of brake and regeneration in low-speed(5㎞/h), middle-speed(10㎞/h) and high-speed(15㎞/h), applying the regenerating system which widely used to HEV to electric bicycle. The efficiency is confirmed using Microchip"s dsPIC30F6015 by controlling 300W BLDC motor with recognized the electric bicycle.
