Development of Simulator for Hierarchical Battery Management System

Battery life investigation of a hybrid energy management system considering battery temperature effect

This paper investigates the effect of temperature on a hybrid energy storage system with various energy management systems. The hybrid energy storage system consists of a fuel cell, ultracapacitor and battery with associated DC/DC and DC/AC converters. The energy management strategies employed are the state machine control strategy, fuzzy frequency/logic decoupling strategy, minimization strate...

State-Space Battery Modeling for Smart Battery Management System

Battery Management System (BMS) requires an indefinite accurate model. With an aging model, the lifetime of a battery can be precisely predicted. The mathematical model in terms of state variables is presented in this preliminary work involving smart BMS system. This work is crucial as the state space model is able to mimic the complex dynamic behavior of a battery system. A numerical case stud...

A Hierarchical Production Planning System Simulator

This research develops and demonstrates a Hierarchical Production Planning System Simulator (HPPSS) for the analysis of feedback-and-control mechanisms between linear programming models at two levels within a Hierarchical Production Planning (HPP) system. This work focuses on planning levels dealing with tactical decisions. Three areas distinguish it from prior research. First, the HPPSS allows...

A Modular Battery Management System for HEVs

Proper electric and thermal management of an HEV battery pack, consisting of many modules of cells, is imperative. During operation, voltage and temperature differences in the modules/cells can lead to electrical imbalances from module to module and decrease pack performance by as much as 25%. An active battery management system (BMS) is a must to monitor, control, and balance the pack. The Uni...
