Automatic Power Management And Monitoring System For Electric Vehicles

In this paper, electric vehicle technology which is recharged in the combination of multi sources (when it is plugged in to a power source from the grid and also from renewable energies like solar). However the solar radiation never remains constant. It keeps on varying throughout the day. The need of the hour is to deliver a constant voltage to the grid irrespective of the variation in temperatures and solar insolation. We have designed a circuit such that it delivers constant and stepped up dc voltage to the load. At various insolation levels, the load is varied and the corresponding variation in the input voltage and current to the buck-boost converter is corrected and noted. These electric vehicles help to keep the environment clean by reducing the amount of toxins emitted from standard exhaust systems and lower operating cost than the conventional internal combustion engine based vehicle. The main objective of this project is used to improve battery performance/efficiency as well as life together using converter and also monitoring the system using PIC16F877A. The effectiveness of the system is verified through the simulations using Simulink/ MATLAB (R2013a) package.
