The On-Road Testing Analysis of Travel Patterns and the Integrated Energy Consumption of the New Energy Vehicles in China

It is of great importance to test and evaluate the on-road energy use characteristics and its impact factors of the new energy vehicles to support the industrial policies and national energy saving and emission control strategy making. This research have collected 180,000 km high frequent travel data of 30 new energy vehicle samples belonging to 4 typical models, building the database of travel characteristics and energy consumption. The energy use characteristics and its impact analysis of electric and plug-in hybrid vehicles are done in terms of trip chain and short trip perspective. The results show that, the trip chains of electric vehicles mainly distribute between 60~90 km, which has large probability to travel in low speed with AC on in downtown and the mileage anxiety exists; for the plug-in, they could cover daily city travel averagely but, all the conditions should be advantaged to enlarge the mileage ratio of electrified range to reach the current type-approval fuel economy.
