Battery Monitoring System Using Labview

Abstract

In order to obtain the rated service life and the longest possible run times of a battery, it must be monitored & pro-actively maintained. The amount energy stored and used from batteries has quadrupled over the last decade. This calls for an effective battery monitoring system that can predict the life of a battery with respect to the load connected, and accounts for battery degradation over time. Therefore, we intend to create a real time battery monitoring system that will be able to provide the user with the constant state of charge of their battery, time till empty if run on current load and the degradation occurring to the battery over time as a function of its temperature, load connected. Human intervention is not required for recording the instantaneous values. To simplify this job a LabVIEW Graphical User Interface (GUI) is made to automate the battery monitoring system.

This project has a GUI which has a provision to read voltage, current and temperature of the battery while it is charging or discharging. There is a provision for the data to be recorded in the database with all voltage, current, time for charging and discharging. This helps to know the actual problem of the battery and avoids damage of it by knowing it in prior.
