This paper describes a power electronic system that, among other possibilities, can be used to charge electric vehicle batteries. A large-signal linear multirate digital controller for the charging current permits the charger to track and deliver a desired current trajectory for a wide range of loads. This controller simultaneously ensures that the charger draws power from the electric utility ...

This paper develops a trace and prediction model for the energy load imposed by electric vehicle charging in Jeju City, based on artificial neural networks as well as the massive amount of charger monitoring streams collected for about 1 year. The monitoring system generates a data archive, in which a single report essentially embraces charger ID, timestamp, and battery level reading. Our data ...

In this paper, we investigate the mobile charging in rechargeable sensor networks. By utilizing the historic charging information, the mobile charger can prefetch the charging requests from sensor nodes before they are sent out, and thus both the charging latency of sensor nodes and the travel distance of mobile charger can be reduced. Furthermore, by controlling the amount of energy to charge ...

A power management controller circuit with a switched-capacitor mode down-regulator and a battery charger block for semi-active radio-frequency identification (RFID) tags was proposed and fabricated. The major achievement of the proposed switched-capacitor mode downregulator and battery charger block is providing a low standby current internal voltage supply circuit and self-controlled thin fil...

This paper presents a low cost reduced instruction set computer (RISC) implementation of an intelligent ultra fast charger for a nickel–cadmium (Ni–Cd) battery. The charger employs a genetic algorithm (GA) trained generalized regression neural network (GRNN) as a key to ultra fast charging while avoiding battery damage. The tradeoff between mean square error (MSE) and the computational burden o...

This paper illustrates the study of three isolated zero voltage switched (ZVS) PWM full bridge (FB) converters to charge the high voltage battery in the charger of electric vehicle (EV). EV battery chargers have several challenges such as high efficiency, high reliability, low cost, isolation, and high power density. The cost of magnetic and filter components in the battery charger is reduced w...

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...

The future charging of the growing fleet of Electric Vehicles (EV) requires new solutions that guarantee a better efficiency and widely spread chargers. Both in fast charging and in slow charging of the electric vehicle (EV) and hybrid electric vehicle (HEV), the wireless charger is the better choice. The wired charger is limited by its cabling and relatively lower output voltage, while the con...
