Solar System Charging Station For Electrical Vehical.

Abstract

A solar charging station is meant so that vehicles are fully charged and are environmentally safe. This technique transforms solar power into electricity and stores it in a battery bank. If electric vehicles must be truly imperishable, it's essential to charge them from sustainable sources of electricity, like solar or wind energy. In this paper, the solar charging station gives the electricity to charge the battery. The charging station has integrated battery storage that allows for off-grid operation. The DC charging uses the DC power from the photovoltaic panels directly for charging the battery of the vehicle without the utilization of an AC charging adapter. Solar energy is converted to electrical energy by photo-voltaic cells. PV systems are not linear therefore special methods are used to extract the maximum available power. We aim to obtain maximum power at the load side from the solar panel. So basic network theorem is applied called the maximum power point theorem. Various MPPT (Maximum Power Point Tracking) techniques are utilized for the tracking of MPPT but here we have the P&O technique. The MPPT algorithm is an important process to ensure the best utilization of PV panels. Maximum power point tracking of solar module aiming to improve the conversion efficiency of the solar module. Various tracking algorithms are available for this purpose. Implementing these techniques required sensing the panel voltage, panel current, battery voltage, and battery current. Sensing the voltage is easy and can be made at a very less cost. For the current sensing standard, Hall-Effect current sensor is generally used in the MPPT algorithm
