Study on the Fuel-Saving Efficiency of Electric Vehicles under Empirical Test

Abstract:

This study constitutes an empirical fleet with electric vehicles (EV) and conventional vehicles (CV) which used by a large number of test participants who have different travel mileage to research the fuel-saving efficiency of EVs under daily travel mode within six months. Experimental results show that there is a great difference in energy consumption when EV running under different average temperatures and seasons. During summer (high temperature) and winter (low temperature) the energy consumption is bigger and the average electric consumption of 100-kilometer is 12.3 kWh/100km. The fuel-saving efficiency of EV in Tianjin empirical test is 66.7% and which is 74.8% in ten typical cities in China. EV has better fuel-saving effect in the whole country. The fuel-saving efficiency in working-days and rest-days is 80.3% and 42.2% respectively. EV has the best fuel-saving effect in working-days.
