Recent advances in wireless energy transfer technology propels the developments of renewable sensor networks. To sustain the operation of a sensor network, a mobile charger is used to recharge each node. Consider each node’s recharge request as a task with a soft due time, the mobile charger needs to dynamically schedule these tasks. This scheduling problem is very challenging, since both the n...

Ultracapacitor usually use as a short-term duration electrical energy storage because it has several advantages, like high power density (5kW/kg), long lifecycle and very good charge/discharge efficiency. Unlike batteries, ultracapacitors may be charged and discharged at similar rates. This is very useful in energy recovery systems such as dynamic braking of transport systems. Here are a few ch...

Battery charging and State-Of-Charge management is one of the main relevant issues for developing mobile autonomous robots. This paper presents a complete development of an battery charger for an autonomous mobile robot and a discussion of SOC estimation models. Initially a charger prototype, based on a HalfBridge DC-DC converter, was developed and tested. Furthermore, the MATLAB SimPowerSystem...

Nowadays, because of the need to decrease fuel consumption and greenhouse gas emissions and also their capability of exchanging power with the grid and regulating the frequency and voltage of the grid at different times of the day, electric vehicles are used more than before all across the world. It is highly important to pay attention to the efficiency, and decrease in the weight and volume of...

This paper proposes a zeta converter-based battery charger. A Zeta converter is DC-DC that has non inverted output and works as buck-boost converter. The can be adjusted to get maximum power from the PV system. used charge EV battery. Using P & O method Simulation done through MATLAB Hardware consists of Converter which fed Array triggered using Arduino nano, therefore gets charged by Conve...

In this paper, a digital battery capacity meter with an integrated charger is developed and built. Also, the software used to control monitor microcontroller of device from PC has been developed, so that data obtained measurement can be processed compared further using one available spreadsheet packages. Due widespread use electrochemical energy sources, whether primary ones or type, it extreme...
