Battery Management System, Balancing Modularization based on Single Switched Capacitor and Bi-directional DC/DC Converter with the Auxiliary Battery Vrije Universiteit Brussel

Mohamed Ali Abdelfattah Hamoda Daowd, Antoine Mailier, Noshin Omar, Philippe Lataire, Peter Van Den Bossche, Joeri Van Mierlo
Lithium based batteries are considered as most advanced batteries technology, which can be designed for high energy or high power storage systems [1]. However, the battery cells are never fully identical due to the fabrication process, surrounding environment factors and differences between the cells tend to grow if no measures are taken. In order to have a high performance battery system, the battery cells should be continuously balanced for ...

Single Switched Capacitor Battery Balancing System Enhancements Vrije Universiteit Brussel

Mohamed Ali Abdelfattah Hamoda Daowd, Antoine Mailier, Noshin Omar, Peter Van Den Bossche, Joeri Van Mierlo
Battery management systems (BMS) are a key element in electric vehicle energy storage systems. The BMS performs several functions concerning to the battery system, its key task being the battery cells' balancing. Battery cell unbalancing does hamper the electric vehicles' performance, with differing individual cell voltages decreasing the battery pack capacity and cells' lifetime, leading to the eventual failure of the total battery system. ...

A Review of Passive and Active Battery Balancing based on MATLAB/Simulink (in press) Vrije Universiteit Brussel

Mohamed Ali Abdelfattah Hamoda Daowd, Noshin Omar, Peter Van Den Bossche, Joeri Van Mierlo
Battery systems are affected by many factors, a key one being the cells unbalancing. Without the balancing system, the individual cell voltages will differ over time, battery pack capacity will decrease quickly. That will result in the failure of the total battery system. Thus cell balancing acts an important role on the battery life preserving. Different cell balancing methodologies have been proposed for battery pack. This paper presents a ...

Capacitor Based Battery Balancing System Vrije Universiteit Brussel

Mohamed Ali Abdelfattah Hamoda Daowd, Noshin Omar, Peter Van Den Bossche, Joeri Van Mierlo
Battery systems as a vital part of the electrical vehicles are facing major difficulty which is the cells unbalancing. The cells unbalancing leads to individual cell voltages will differ over time, decreasing the battery pack capacity that consequently will fail of the total battery system. In addition, cell equalization acts an important role on the battery life preserving. Several cell balancing topologies have been proposed for battery pack ...

Voltage Vector Redundancy Exploitation for Battery Balancing in Three-Phase CHB-Based Modular Energy Storage Systems Vrije Universiteit Brussel

Ashkan Pirooz, Yousef Firouz, Joeri Van Mierlo, Maitane Berecibar
This article presents a flexible controller algorithm for bidirectional modular cascaded H-bridge (CHB)-based battery storage systems. The primary objectives are to maintain high-quality power on the AC-side while balancing DC-side battery voltages under charging or discharging operations. The proposed algorithm is based on finite-set model predictive current control (FSMPC) technique which performs in-phase and phase voltage equalization in two ...

Fast Active Balancing System using Multi-level DC Converter for Efficient AC-coupled Battery Systems in Stationary Applications Vrije Universiteit Brussel

Abdul Mannan Rauf, Mohamed Abdel Monem, Thomas Geury, Mohamed El Baghdadi, Omar Hegazy

This paper proposes a cascaded half-bridge multilevel converter (MLC) topology for stationary battery energy storage systems (BESSs). Commonly, many low-voltage battery modules are connected in series to create the DC-link of the inverter. Due to difference in electrochemical characteristics, voltage imbalance happens among different modules during the charge-discharge operation, which negatively affects the lifetime of the battery pack. The ...

SuperLib Project: Advanced Dual-Cell Battery Concept for Battery Electric Vehicles Vrije Universiteit Brussel

Noshin Omar, Thierry Coosemans, Joseph Martin, Valerie Sauvant-Moynot, Justin Salminen, Hennige Volker, Joeri Van Mierlo, Peter Van Den Bossche
This paper describes the Advanced Dual-Cell Battery Concept for Battery Electric Vehicles in the framework of the European Seventh Framework Programme (FP7). The project investigates a well promised new energy concept, whereby high energy is combined with high power dimensioned batteries on cell level. The proposed methodology should allow extending the battery life cycle by imposing peak power at the high power cell and supplying energy by main ...
