Battery Charge Controller for Electric Bike using Renewable Energy Source

Abstract: This paper presents a solar power assisted battery charger for electric bike. One of the renewable energy sources – solar energy is taken into consideration as an input to the battery of the Electric bike for charging. Also the availability of the AC mains supply in the absence of adequate solar energy i.e. in cloudy conditions and at night time is considered and accordingly the suited controller is designed and same is presented in this paper. Both the solar energy and the AC mains supply are controlled by a microcontroller and results and discussed here. This paper represents the energy saving by the use of available renewable source.
