A Case Study on Testing and Performance Evaluation of Electric Motorcycles to Discuss the Environmental Impact of Urban Area in Macao

The environmental impact and energy crisis of using motorcycles in urban area have urged the rapid development of electric motorcycles (EMs) in Macao in recent years. This work mainly presents the findings of a small-scale electric motorcycle test in Macao. The trial EMs are arranged for a series of tests, such as maximum thirty minutes speed, complete battery discharge, hill starting ability and so on, which are compared with the standard specification. Particularly, the normalized mains-to-wheel energy of EM consumes 1.5 kW¡Ph averagely. Expressed in greenhouse gas (GHG) emission, EM emits 388 g CO2 per kilometer, 66% less than gasoline motorcycle. Furthermore, EMs can achieve zero-urban-emission of carbon dioxide benefitting from the remote location of power station in Macao. This study shows that EM can effective be adopted at Macao for an effective emission control.
