Solar energy, despite being inexhaustible, has a major shortcoming; it is intermittent. As a result, there’s a need for it to be stored for later use. The widely used energy storage in photovoltaic system applications is the leadacid battery and the knowledge of its state-of-charge (SOC) is important in effecting efficient control and energy management. However, SOC cannot be measured while the...

based on the problems caused by today conventional vehicles, much attention has been put on the fuel cell vehicles researches. however, using a fuel cell system is not adequate alone in transportation applications, because the load power profile includes transient that is not compatible with the fuel cell dynamic. to resolve this problem, hybridization of the fuel cell and energy storage device...

Athletes usually deal with injuries and pain. They seem to have similar pain threshold when compared to non-athletes, although they have higher pain tolerance and the exact cause for that is unknown. High levels for pain tolerance and control can improve performance and time for injury recovery. The literature shows that use of coping strategies can increase pain control; possible differences o...

The paper concerns the design and development of large electric energy storage systems made lithium cells. Most research advances in lithium-ion battery management focus solely on safety, functionality, improvement procedures for assessing performance without considering their efficiency. presents an alternative approach to analysis modular systems. A system dedicated wireless communication wer...

The growing popularity of electric vehicles on a worldwide scale leads to further research monitor their performance. use Internet Things (IoT) technology will make it easier integrate the automated real-time monitoring system with current vehicle technology. great majority rechargeable lithium-ion batteries. Use batteries creates an overcharging situation in battery, which significantly decrea...

Wind is the world’s fastest growing energy source today. During normal operation, the wind generating systems have large fluctuations due to sudden wind speed changes. The Possible solution for this problem is to use hybrid energy storage management. Thus the performance of this system can be improved by using battery as well as super capacitor which is integrated with wind turbine generators. ...

In most low-power systems, power management is generally thought of as being an ability to switch certain parts of a system off or put them in a low-power state when they are not required, and to manage the charging of a battery. While these are important aspects of low-power electronics powered by energy harvesters, there are much more fundamental reasons for requiring power electronics in an ...

State of charge (SOC) is an essential parameter for battery management system (BMS). Accurate estimation of SOC ensures battery work within a reasonable range, which can prevent over-charge or overdischarge damage to extend battery life. The third-order RC equivalent circuit model is established to describe the characteristics of battery, in which the parameters can be identified by the dischar...

This study investigated the heat problems that occur during the operation of power batteries, especially thermal runaway, which usually take place in high temperature environments. The study was conducted on a ternary polymer lithium-ion battery. In addition, a lumped parameter thermal model was established to analyze the thermal behavior of the electric bus battery system under the operation c...
