EVs provide a promising green solution to reduce dependence on fossil fuel and the emission of greenhouse gas. This article concerns hybrid EV systems that contain both wired charging and wireless charging vehicles. To the best of our knowledge, we are the first to discuss how to jointly use these two types of charging methods whose advantages are complementary to each other; for example, wireless...
In this study, we reported the design and application of hierarchical porous Graphdiyne Nanowall (GDY−NW) for energy storage device as lithium−ion batteries (LIBs) and capacitors (LICs). The unique hierarchical porous with the presence of butadiyne linkages comprising sp− and sp2− hybridized carbon atoms reinforces not only providing rich active sites for lithium storage, but also the efficient pathways...
This paper proposes the two-stage control structure which is composed of battery management unit and central management unit in order to improve the monitoring and management technology of integrated power supply in power system. The paper presents a battery management system (BMS) design scheme. We designed its hardware circuit and verified in the laboratory conditions. The results show that the...
This paper introduces the entire roadmap and detailed research methods of our NSFC project. A three-stage roadmap is proposed for energy store application of marine power station, and called upon to solve the key issues of health feature rapid extraction and modeling for battery pack. Efficient numerical modeling, rapid ICA and EIS testing and degradation of key features investigating makes the acquirement...
Wireless Body Area Networks (WBANs) have become a leading solution in Mobile Health (mHealth). Typically, a WBAN consists of in-body or around-body sensor nodes for collecting data of physiological feature. For a WBAN to provide high throughput and low delay in an energy-efficient way, designing an efficient Medium Access Control (MAC) protocol is of paramount importance because the MAC layer coordinates...
In Energy-Harvesting Wireless Body Area Networks (EH-WBANs), how to realize a power management strategy to enable lifetime operation is one of the most concern problems. To solve this problem, a feasible solution should be used to manage the harvested energy in sensor nodes in an EH-WBAN. So far, there are extensive studies about this issue for EH-WBANs. Unfortunately, the significant character of...
With the motivation of high efficiency, energy saving and environmental protection, a solar LED lighting system was designed. The system implemented maximum power point tracking technology (MPPT) and precise three-section storage battery charging by charging control, which improves the utilization ratio and lifetime of solar cell, enhancing the energy conversion efficiency. The use of LED lighting...
