PROJECT TITLE :

Battery Modelling and Simulation Using a Programmable Testing Equipment

ABSTRACT:

A lithium-ion battery cell is examined and modelled in this paper. Two programmable power units, an electronic load and a power supply, were used to build a battery testing system for the cell under consideration. Within the National Instruments (NI) LabVIEW environment, the software/hardware interface was built to connect with them. Using this specialised laboratory equipment, charging and discharging cycles can be applied based on custom load profiles. There is a description of the battery modelling and parameter identification technique. SOC (State Of Charge) was estimated using this model under dynamic loading. Implementation and comparison of the most widely used battery modelling and SOC estimate algorithms.
