Transport is a vital sector for achieving sustainable development. The evolution of the electric vehicle subject to charging time, accessibility, and facility. On-board chargers are broadly used in battery-electric plug-in-electric fleets due their easy installation low cost. Also, it must be powerful extremely efficient because constrained interior area quick times. minimization hardware requi...

Because the charging process for Li+ batteries can take an hour or longer, testing a Li+ battery charger using its natural load (i.e., a battery) is time consuming and inconvenient. This application note presents a simple circuit for simulating the behavior of a Li+ battery, thus providing a more convenient method for testing Li+ battery chargers than using real batteries. A similar version of ...

Rising greenhouse gas emissions stemming from fossil fuel-driven vehicles are causing damage to the environment. To counteract this, one solution is adoption of electric (EV) for transportation requirements. In this regard, category EVs that requires special attention light vehicle (LEV), mainly because their wide potential in public transportation—especially developing countries. realise wides...

OBJECTIVES The aim of this study was to assess personal exposure to fibres, crystalline silica, silicon carbide (SiC) and sulphur dioxide in the Norwegian SiC industry. METHODS Approximately 720 fibre samples, 720 respirable dust samples and 1400 total dust samples were collected from randomly chosen workers from the furnace, processing and maintenance departments in all three Norwegian SiC p...

The increase of electric vehicle (EV) battery chargers connected to electric networks could lead to future harmonic problems in power systems. These loads are nonlinear devices that inject harmonic currents and pollute network voltages. Thus, battery charger modeling must be studied in detail to determine their harmonic emissions and prevent future problems. This paper investigates EV battery c...

A PowerPC-centred 110 VAC/2.5 kW full-bridge isolated battery charger was developed for the plug-in hybrid electric vehicle (PHEV). Genetic algorithm was adopted to optimise the system key parameters. Phase-shift-based operation modes were analysed in detail. The system-level safe operational area and other practical design considerations were discussed in detail. Experiments validated the desi...

ISSN 2250 – 1088 | © 2011 Bonfring Abstract--This paper is a detailed study on methods of battery charging with Buck Resonant converter using soft switching techniques like ZVS and ZCS. This study also presents the circuit configuration with the least components to realize a highly efficient solar energy battery charger with a zero-voltage and zero current switching resonant converter.

The main purpose of this paper is to develop a novel application of a resonant switch converter for battery chargers. A zero-current-switching ZCS converter with a quasiresonant converter QRC was used as the main structure. The proposed ZCS dc–dc battery charger has a straightforward structure, low cost, easy control, and high efficiency. The operating principles and design procedure of the pro...

The demand for electric vehicles continues to grow, as evidenced by global sales of reaching 2.2 million in 2019 and more than doubling 6.6 2021. rapid growth renewable energies (EVs) necessitates the use microgrids, which are a promising solution problem integrating large-scale renewables EVs into power system. Besides, essential policy support provided government is an increase availability p...

Quantum battery works as a micro- or nanodevice to store and redistribute energy at the quantum level. Here we propose spin-charger protocol, in which cells are charged by finite number of spins through general Heisenberg $XY$ interaction. Under isotropic interaction, protocol is endowed with higher capacity terms maximum stored than conventional protocols, where continuous-variable system, e.g...
