Abstract
The expected increase in the penetration of electric vehicles (EV) and plug-in hybrid electric vehicles (PHEV) will produce unbalanced conditions, reactive power consumption and current harmonics drawn by the battery charging equipment, causing a great impact on the power quality of the future smart grid. A single-phase semi-fast electric vehicle battery charger is proposed in this paper. This ac on-board charging equipment can operate in grid-to-vehicle (G2V) mode, and also in vehicle-to-grid (V2G) mode, transferring the battery energy to the grid when the vehicle is parked. The charger is controlled with a Perfect Harmonic Cancellation (PHC) strategy, contributing to improve the grid power quality, since the current demanded or injected has no harmonic content and a high power factor. Hall-effect current and voltage transducers have been used in the sensor stage to carry out this control strategy. Experimental results with a laboratory prototype are presented.
Highlights
Widespread adoption of plug-in hybrid electric vehicles (PHEV) and electric vehicles (EV) could reduce greenhouse gas emissions from vehicles, decrease petroleum use and constitute an effective solution from the economical point of view, since the cost of electricity per mile of driving is less than one-fifth that of gasoline [1,2]
Most of the battery chargers behave as nonlinear loads, so the increase in the penetration of EV and PHEV will cause unbalanced conditions, reactive power consumption and current harmonics drawn by the battery chargers, producing disturbances on the electrical power system
A novel control strategy for an on-board semi-fast battery charging equipment has been proposed in this paper
Summary
Alternative and sustainable transportation methods have become more attractive options in the last years due to the high fuel prices, environmental concerns and the demand for renewable energy. In order to comply with this standard, it is necessary to develop new battery charging equipment with higher power quality In this way, novel control strategies capable to meet the requirements of the standard have to be implemented in the coming years. Novel control strategies capable to meet the requirements of the standard have to be implemented in the coming years These chargers will reduce the impact of EVs and PHEVs on the electric infrastructure, eliminating the non-linear behavior of actual battery chargers and achieving higher power transfer efficiency, minimizing line losses in the power system. A high efficiency and high power factor bidirectional charging equipment is proposed with a simple and low-cost topology and provided with a novel control strategy to reduce the harmonic current demanded or injected into the grid.
