Implementation of Real-time Simulation System for Li-ion Battery Protection Circuit Module

Abstract

In this paper, the implementation result of real-time simulation system for Ii-ion battery protection circuit module (PCM) is presented. Battery protection is one of the most important factors to protect the electrical system. Especially, as the usage of the battery increases, an accurate monitoring of battery state becomes necessary for system safety. Therefore, we implement the PCM consisting of multiple ICs for battery protection and simulation board functioning as voltage load and power supply. The simulation board can show voltage and current autonomously, and also can be linked to the developed PC monitoring program with state-of-charge (SOC) estimation. Finally, the real-time simulation and output monitoring for battery protection is presented.
