Abstract

Battery Management System for solar application system consists of lead asid battery serving as its energy storage elements. The most commonly used storage technology for solar application is the lead acid battery. This system is constructed for the purpose of gathering data on different charge and discharge current flow through the storage and load. The aim of this project is to analyze a charging process with battery utilization in a way to optimize load variation and making the overall system more reliable. The solar charge controller with Pulse Width Modulation (PWM) technique making the solar panels able to optimize under varying illumination level. The battery charging from different power of solar panel is the key point to found the suitable sources to power up these prototype. The new system configuration with parallel is to create a optimal storage. According to the size of battery characteristic, the battery management is optimized for longer life time and batter performance. Charge and discharge of SLA battery at 50% of battery capacity conducted on the static load resistor through 90 watt laptop adaptor. Voltage and current were recorded during an increment of out power from 10W to 70W. The experimental result analyzed through this project carry out via actual measurement and hardware that has been developed. This prototype of portable dc power supply has been developed and tested under lab experimental . All results were verified through experiment with the load variation that has been done.
