This paper presents an optimized design and implementation of vertical axis wind turbine (VAWT) for battery charging applications. VAWT is becoming more popular than a horizontal axis wind turbine (HAWT) which is used conventionally. Most of the VAWTs are installed in high wind speed areas. An optimized design proposed in this paper aims to make VAWT to be efficient and operative even at low wind speeds.This turbine is specially designed to serve the purpose in low wind speed areas where wind speed is not crossing beyond 5m/s. Based on the output voltage of the turbine, converter can be designed to boost the output voltage and charge a battery of 12V. The main objective of operation of VAWT is charging of a battery.The turbine output has to be converted into DC since the output obtained from a wind turbine is AC. Turbine blade profiles are aerodynamically shaped with NACA0018 series. Modifications are carried over NACA0018 blade profile and an optimized design is obtained. Basic vector analysis and laws of motion are applied to test the performance of a new design theoretically. For simplicity in designing NACA0018 symmetrical profile is used and a model is fabricated as per the design parameters and tested practically.
