This paper presents the design and construction of charge controller for wind energy source. The charge controller is a small prototype that is suitable to charge small battery. The maximum charging current of the charge controller is about 7 A. The charge controller is designed using PIC 16F877A microcontroller, liquid-crystal display (LCD), silicon-controlled rectifier (SCR), rectifier diodes and other electronic components. The SCR and rectifier diodes in conjunction with other components are used to charge the battery. The battery charging is controlled by the microcontroller circuit. The LCD module displays the status of the battery while it is charging. At the same time the voltage level of the battery is also displayed. The microcontroller controls the charging circuit and diverted the charging current to the diverted load if the battery is fully charged. The microcontroller also produces signal to the audible alarm circuit in the case of full charge battery. The simulation results are based on the ISIS software environments before implementing the hardware description. The experimental results for charge controller are also mentioned.
