Research on Fuel Economy of Hybrid Electric Vehicles

Abstract:

On the road, fuel meter and electric power meter were employed to measure fuel consumption and electricity consumption of two parallel hybrid electric vehicles (PHEVs); Corrected methods recommended by SAE J2711 and GB/T 19754 respectively were used to modify fuel consumption of two vehicles through electricity consumption; According to the result, how total quality and Air-Condition (AC) load affect fuel economy were analyzed. Test results showed that, When K was less than 1%, relative error from calculation results of fuel consumption per 100 km obtained by above two methods was within 0.7%; Compared with AC off condition, fuel consumption per 100 km of PHEVs under AC on condition increased by more than 42%, which caused bad fuel economy, the effect of fuel-saving was decreased by 10% or more accordingly.
