Optimizing the Hybridization Factor for a Parallel Hybrid Electric Small Car

ADVISOR simulations of 75,100 and 125 kW total power, parallel hybrid small cars show that the hybridization factor (HF) giving maximum fuel efficiency (termed optimal HF) for the 75 kW small car is 0.49. For the 100 kW small car the optimal HF is 0.58. For the 125 kW small car, the optimal HF is 0.6. At these hybridization factors, vehicles had the greatest increase in fuel economy over the conventional vehicle without sacrificing performance
