Solar Powered Battery Charging System with Maximum Power Point Tracking

Ahstract- This paper proposes environmental friendly solar based charging system for battery electric vehicles having lithium ion battery. A DC - DC Cuk converter is used for efficient utilization of solar energy. Perturb and Observe algorithm is implemented in converter. State of charge of the battery, battery current and battery voltage are continuously monitored and accordingly the duty ratio of CUK converter is controlled for battery charging. Simulation is done in MATLAB /SIMULINK and results are presented.
