In an electrical energy storage and delivery system, a parallel connection of battery modules can be used to increase the storage capability and power delivery demands. Parallel connection of batteries requires a robust battery management system as batteries may have different operating parameters such as state-of-charge (SoC), open-circuit voltage (OCV), internal resistance or battery chemistr...

As an increasing number of electronic systems are powered by batteries, battery life becomes a primary design consideration. Maximizing battery life requires system designers to develop an understanding of the capabilities and limitations of the batteries that power such systems, and to incorporate battery considerations into the system design process. Recent research has shown that, the amount...

The proton exchange membrane (PEM) fuel cell is a green energy producer which converts chemical energy to electricity in high yield. Alternatively, the vanadium redox flow battery (VRB) is one of the best rechargeable batteries because of its capability to average loads and output power sources. These two systems are modeled by Nernst equation and electrochemical rules. An effective energy gene...

Many efforts are recently being dedicated to developing models that seek to provide insights into the techno-economic benefits of battery storage coupled to photovoltaic (PV) generation system. However, not all models consider the operation of the PV – battery storage system with a feed-in tariff (FiT) incentive, different electricity rates and battery storage unit cost. An electricity customer...

This paper has applied battery pack technologies in battery system based on the characteristics of charging and discharging process and composed big battery pack from single battery cells with MSP430 as micro control unit (MCU). The paper has also designed the monitoring hardware system of main control unit, data monitoring module, as well as the monitoring software of upper computer of CAN com...

Original scientific paper The fast and accurate estimation of state of charge (SOC) of lithium-ion battery is one of the key technologies of battery management system. In view of this nonlinear dynamic system of lithium battery, through the test and analysis of lithium-ion battery hysteresis characteristics, the second-order RC hysteresis model is established, and the cubature Kalman filter alg...

Lithium-based batteries are considered as the most advanced batteries technology, which can be designed for high energy or high power storage systems. 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 ...
