It is necessary to form an energy system in order to deliver the electrical power to a region that delivering energy to them from the national grid is not possible. At the moment, using the hybrid renewable energy systems (HRES) is the suggestion of more articles and scientific books because of environmental problems, nearing to the end of fossil fuels, and challenges including unpredictability...

Battery lifetime has become one of the top usability concerns of mobile systems. While many endeavors have been devoted to improving battery lifetime, they have fallen short in understanding how users interact with batteries. In response, we have conducted a systematic user study on battery use and recharge behavior, an important aspect of user-battery interaction, on both laptop computers and ...

Accurate estimation of the state of charge (SOC) of batteries is one of the key problems in a battery management system. This paper proposes an adaptive SOC estimation method based on unscented Kalman filter algorithms for lithium (Li)-ion batteries. First, an enhanced battery model is proposed to include the impacts due to different discharge rates and temperatures. An adaptive joint estimatio...

In electric vehicles, the battery pack is one of the most important components that strongly influence the system performance. The battery thermal management system (BTMS) is critical to remove the heat generated by the battery pack, which guarantees the appropriate working temperature for the battery pack. Air cooling is one of the most commonly-used solutions among various battery thermal man...

This paper presents a novel intelligent energy management system (IEMS) for a DC microgrid connected to the public utility (PU), photovoltaic (PV) and multi-battery bank (BB). The control objectives of the proposed IEMS system are: (i) to ensure the load sharing (according to the source capacity) among sources, (ii) to reduce the power loss (high efficient) in the system, and (iii) to enhance t...

Rapid growth in the complexity of wireless devices, communication protocols, and applications, combined with slow improvements in battery technologies, have created a “battery gap” that is only projected to increase with advances in wireless communication technologies and applications. Conventional approaches to bridging this gap exploit low-power network protocols and handset architectures. Ho...
