Electric Vehicles are clean due to their zero local emissions and low global emissions. They are also green due to their environmental friendliness, since electricity can be generated by renewable energy sources to achieve sustainable mobility and zero emissions. With the growing concerns on oil price fluctuation, depletion of petroleum resources and global warming, there is fast growing interest in EVs in Macau. Before adapting EVs in Macau, a battery-powered mini EV was recently tested with real driving conditions in sub-tropical environment of Macau. Results revealed the driving range by one full-charge was about 109km, a fuel cost savings of more than 70.4%, and CO2 emission was significantly reduced by 51.9%. Additional reduction could be achieved when more renewable energy sources or non-coal electricity was used for the generation of electricity. Results from the road testing were just a first step of a more comprehensive research. More road conditions with different test routes and longer drives shall be conducted for different groups of vehicle users in the future. On the other hand, an EV charging station was designed and implemented for connecting EVs to the electric power grid for charging. The proposed systems not only provided the fleet administration and load management features, but also shift/delay the battery charging period within the utility's defined off-peak period, conveniently filled the valley in the system load curve without regard to localized effects.
