Being a city with small geographical size limiting the travel range of vehicles, Macau has great potential for implementation of electric vehicles (EVs). With an urbanized city and limited land space, Macau has been faced with problems of road congestion due to rapid growth in car population. Air pollution is also another important concern. EVs provide low emission urban transportation. Researchers and engineers have concentrated on the improvement of EV performance through the advances in batteries, motors, converters, controllers and relevant auxiliaries, with enormous successes. Now, it comes to the stage of commercialization! Before adapting EVs, it is important to understand their performances in Macau. Several projects were launched to investigate the performance of EV, specifically for sub-tropical environment of Macau. Due to the high temperature and humidity, performance of EVs operated in Macau was yet to be understood. Previous experimental studies conducted in the US, Europe or Japan might not reflect the actual local real-road driving conditions. This paper aims to analyze the performance of EVs and compared with internal combustion engine vehicles (ICEVs) and hybrid electric vehicles (HEVs). Viability of EVs will be simulated using both Federal Urban Driving Schedule (FUDS) and Macau Driving Cycle (MDC).
This paper gives an overview of current wireless charging technologies on electric vehicles (EVs) charging. In general, the near-field technologies are preferred over far-field ones. Inductive power transfer and strongly coupled magnetic resonance technologies are chosen for detailed review. Furthermore, special issues related to EV applications are also discussed, namely efficient power supply, misalignment tolerance, multiple pick-up control, simultaneous power and data transmission and shielding methods.
