Design and implementetion of a real-time battery chatacterization platform

Abstract

Batteries play an important role in the performance of power grids including renewable energy systems. In order to obtain the rated service life and the longest possible run time of a battery, it must be monitored and maintained. This calls for an effective real-time characterization platform. Therefore, it is intended to develop a real-time battery monitoring system that will be able to provide the user with battery parameters. Physical involvement is not required for recording the instantaneous values. To simplify this task a LabVIEW based platform is made to automate the battery characterization system. This project is based on a graphical user interface (GUI) that allows users to read the Open Circuit Voltage (OCV), current, and ambient temperature of the battery as it is charging or discharging. There is a possibility for data to be recorded, including voltage, current, charging and discharging times. This assists in recording experimental data which in turn will be used for a precise and efficient estimation of the state of charge as well as for aging study.
