Electric Vehicle (EV) possesses a significant potential to provide clean energy in vehicular technology. To increase the drive cycle efficiency and the driving range of EVs, which is considered to be the key barrier for its successful commercialization, its energy storage technology needs to be improved. The power requirement of an electric vehicle cannot be satisfied by the battery alone as it...

Electrochemical energy storage (EES) devices with high-power density such as capacitors, supercapacitors, and hybrid ion capacitors arouse intensive research passion. Recently, there are many review articles reporting the materials structural design of electrode electrolyte for supercapacitors (HCs), though these reviews always focus on individual or single HCs. Herein, conventional capacitor, ...

To develop electrical busses for applications with a fast recharge system in stations, PVI has been testing some electrical energy components like supercapacitors and batteries with high power density. Neverthless, supercapacitors limit average autonomy between two recharge points, due to their poor energy density. On the other side cycle life of batteries are very dependent on current. To surm...

Batteryless Computational RFID (CRFID) devices present exciting possibilities for ubiquitous computing applications. They require minimal maintenance, are cheap to manufacture, and have small form factors. However, CRFIDs lack autonomy because of the need for constant power from an RFID reader—hindering deployment. In this paper, we propose hybrid power harvesting techniques as a mechanism for ...

We have studied the abrupt and hysteretic changes of resistance in MgObased capacitor devices. The switching behavior is discussed in terms of the formation and rupture of conduction filaments due to the migration of structural defects in the electric field, together with the redox events which affects the mobile carriers. The results presented in this paper suggest that MgO transparent films c...

A single series resonant converter has been designed to balance the voltage level of a storage battery for electric vehicles. The proposed design has been simulated and verified by using two 100F supercapacitors instate of the conventional rechargeable battery. A voltage monitoring circuit detects the voltage condition of the individual capacitor and sends the voltage status to the control circ...
