LEAD ACID BATTERY MODELING FOR ELECTRIC VEHICLE

Abstract

Electrical energy plays an important role in our daily life. It can universally applied and easily be converted into light, heat or mechanical energy. A general problem, however, is that electrical energy can hardly be stored. Capacitors allow its direct storage, but the quantities are small, compared to the demand of most applications. ln general, the storage of electrical energy requires its conversion into another form of energv. Electrical energy is typically obtained through conversion of chemical energy stored in devices such as batteries. In batteries the energy of chemical compounds acts as storage medium, and during discharge, a chemical process occurs that generates. energy which can be drawn from the battery in form, of an electric current at a certain voltage. A computer simulation is developed to examine overall battery design with the MATLAB/Simulink. Battery modelling with this program have error level about 3,63%.
