MODELING AND SIMULATION OF A 300 V LI-ION BATTERY SYSTEM WITH A DC MACHINE AND VARIABLE LOAD
Abstract
This paper presents the modeling and simulation of an electrical energy management system that integrates a 300 V, 8 Ah lithium-ion battery, a DC shunt machine, and a variable DC load using NEPLAN simulation software. The main purpose of this work is to investigate the performance and control behavior of a hybrid electrical system where the power flow is automatically regulated according to the State of Charge (SOC) of the battery. The DC machine alternates between motor and generator modes depending on the SOC level. When the SOC drops below 35%, a negative mechanical torque of -150 Nm is applied to the DC machine to initiate regenerative operation. In this mode, the machine recharges the battery while simultaneously delivering part of the required load current. When the SOC exceeds 85%, regenerative mode is deactivated, and the battery becomes the sole energy source again. The CCT (Conditional Control Trigger) block in NEPLAN is used to implement this logic. Simulation results confirm the effectiveness of this control approach in maintaining the battery-s SOC within safe operating limits, extending battery life, and improving overall energy efficiency. The developed model serves as a simplified, yet practical representation of hybrid energy systems commonly found in electric vehicles and renewable energy applications.
