Solar Energy is a smooth and RE Strength aid and is on its manner to high stage penetration inside the global strength basket. However, there are several demanding situations related to Solar Energy, like intermittency, restricted dispatch capacity and non-storability. Non-storability in a standalone PV device can be mitigated by using incorporating strength garage gadgets like battery to store the electric strength produced with the aid of solar panel while the solar is shining and to supply energy when the sun isn't shining. Batteries are, therefore, one of the essential aspects in the standalone PV system. And regularly the weakest link in PV systems because it impacts the maintenance price and reliability of the system. This project includes solar based battery charging station, microcontroller based totally, sun powered battery charging device. The developed system includes (i) solar panel (ii) At-Mega 328 interfaces for battery control capabilities, (iii) LCD show for no of batteries connected (iv) IOT module also used. The developed sun powered battery charging station. The main aim of this project is to charge our battery smartly by using electric supply as well as solar energy for electric vehicle. In this project is to charge our battery smartly and also discharger it properly without any damage to our battery and charging circuit. For proper charging we are using balancing method and for charging of this battery we are using three different modes each mode has its own benefits.
