Abstract

The object of this study is to regulate charge and discharge currents in battery systems and its affect on thermal behavior under dynamic battery operating conditions. The problem to be solved is the development of battery management framework which accounts for charging current regulation and a load shedding mechanism for discharge current regulation for temperature and voltage control of battery bank.

Simulation results demonstrate that the proposed hybrid framework for the battery control system maintains stable temperature levels during both charging and discharging cycles, where during charging the current is regulated based on terminal voltage, temperature and rate of change of temperature, while during discharging control is based on temperature and rate of change of both temperature rise and voltage drop.

The distinctive feature of the proposed framework is the hybrid control structure that applies different regulation strategies for charging and discharging processes by using fuzzy logic controllers. In this approach, fuzzy logic adjusts the charging current according to the state of charge, voltage, and temperature of the battery cells, at the same time load shedding and load transfer regulate the discharge current to maintain safe operating conditions.

The proposed system was simulated in MATLAB with 3 charge–discharge cycles. It maintained temperature within 45°C setpoint with minimal overshoot and voltage drop amount not more than 25% nominal battery bank voltage.

The results can be applied to the development of battery management systems for battery banks in energy storage, electrical vehicles, essential power supplies in industrial applications, and solar/wind power generation system
