Due to many damages that human activities have imposed on the environment, authorities, manufacturers, and industry owners have taken into account the development of supply chain more than ever. One of the most influential and essential human activities in the supply chain are transportation which green vehicles such as electric vehicles (EVs) are expected to generate higher economic and enviro...

The pulse-based charging method for battery cells has been recognized as a fast and efficient way to overcome the shortcoming of a slow charging time in distributed battery cells, which is regarded as a connection of cells such as the Internet of Things (IoT). The pulse frequency for controlling the battery charge duration is dynamically controlled within a certain range in order to inject the ...

The study of the battery charge process as the only power storage agent in off-grid systems is of significant importance. The battery charge process has different modes, and the battery in these modes is dependent on the amount of charge. In order to charge the battery in off-grid systems, two charge controllers including Pulse Width Modulation (PWM) and Maximum Power Point Tracker (MPPT) are c...

This paper is devoted to the infrastructure issues arising from the ultrafast charging of electric vehicles in the timeframe of ~5 minutes. To mitigate variances and peaks caused by high energy transfer rate and pulse-like load, an ultrafast charging station must be partially decoupled from the utility grid by the usage of intermediate energy buffers. The perspective charging station load and i...

Battery management system monitors and mitigates the operation of battery cells and stacks and is important for battery safety and reliability. This paper presents a dual-objective optimal charging strategy for two types of Li-ion batteries, which considers the conflict objectives of charging time and charging loss. The battery models developed in a prior research are used in the charging optim...

A new bidirectional isolated Zero-VoltageSwitching (ZVS) DC-DC converter with nonpulsating input and output current is proposed. This converter is ideally suited for battery charging application and is applied as a submodule in a battery storage system based on a modular multilevel converter (MC). The current output of the proposed DC-DC converter enables small current ripple for directly inter...

This paper presents a comparative analysis of electric vehicles (EV) charging devices impact on microgrid. Increased load variation may create a need for upgrades in grid infrastructure. For this purpose a set of typical load profiles of EV charging modes is studied and presented. A software implementation and a 24h case study of low voltage distribution network with EV charging devices is pres...

Energy poverty at the household level is a serious hindrance to economic and social development, especially in off-grid, remote villages in the developing world. Some initiatives have sought to provide these households with resources such as renewable generation units and electric batteries to enable access to electricity. At present, these resources are operated in isolation, fulfilling indivi...

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...

Abstract Presented work has made an attempt to establish details of connectivity of Wind Farms with isolated installations. Paper has shown ACDC-AC connectivity of wind farm through Rectifier inverter to an AC load. Mat Lab simulation results of wind farm connectivity to an AC load of lumped type is done. Developed work has focussed on necessity of energy storage during high wind situations so ...
