Design, Construction and Implementation of a Highly Efficient, Lightweight and Cost Effective Battery Charger for Electric Easy Bikes Khosru M. Salim, Md. Jasim Uddin, M. Ishtiaque Rahman, Mohammad Rejwan Uddin Department of Electrical and Electronic Engineering Independent University, Bangladesh Dhaka, Bangladesh khosru@.bd jasimuddinjosh@ ishtiaque_rahman@ rejwanuddin@ Abstract— Electric three-wheeler auto rickshaws known as easy rickshaws known as easy bikes are becoming more and more bikes are becoming quite common in Bangladesh. Due to obvious popular. The charging stations all employ the conventional advantages offered by these vehicles such as zero carbon emission and no requirement of gas encourages people to transition from traditional fuel-operated vehicle to electric improving the efficiency of easy bike battery chargers. Using vehicles. The battery charging stations for these vehicles employ bulky chargers containing iron core transformers with maximum iron core charger which is only about 80% efficient. Hence, there exists an excellent opportunity to save energy by the proposed charger, it is possible to achieve efficiencies of the order of 90%. efficiency around 80%. As a country which suffers from power shortages, it is highly desirable to have a charger that is more efficient. In this paper, a new type of charger is proposed which A considerable amount of research has been done over the uses a ferrite core transformer. A prototype of this charger is years regarding the various aspects of electric vehicle built and compared with a conventional charger. It is found from charging. Pellitteri et al [2] proposed an efficient wireless the experiments that the proposed charger exhibits efficiency more than 90%. In addition, the proposed charger weighs only about 2 kilograms, whereas
