In recent times, Bangladesh is advancing towards Electric Vehicle system; popularly known as the EV system and one of its most prominent application we see these days are the motor operated rickshaws. Although the motors in these rickshaws run in rechargeable batteries it would be feasible to run them on solar power at some time and so in this paper we aim to develop a battery model for battery for a photovoltaic system that can be used in EV systems. In stand-alone photovoltaic power systems, the electrical energy produced by the photovoltaic panels cannot always be used directly. As the demand from the load does not always equal the solar panel capacity, battery banks are generally used. This work aims to study the charging and discharging mechanism of batteries used in photovoltaic systems and develop an electrical model of the battery that will take account of various factors such as charging and discharging current, state of charge, temperature etc.
