CURRENT HYBRID ELECTRIC VEHICLE PERFORMANCE BASED ON TEMPORAL DATA FROM THE WORLD'S LARGEST HEV FLEET

The United States Department of Energy (DOE) procured new data collection equipment for the 42 vehicles registered to compete in the 1994 Hybrid Electric Vehicle (HEV) Challenge, increasing the amount of information gathered from the world's largest fleet of HEVs. Data were collected through an on-board data storage device and then analyzed to determine effects of different hybrid control strategies on energy efficiency and driving performance. In this paper, the results of parallel hybrid versus series hybrids with respect to energy usage and acceleration performance are examined, and the efficiency and performance of the power-assist types are compared to that of the range-extender types. Because onboard and off-board electrical charging performance is critical to an efficient vehicle energy use cycle, charging performance is presented and changes and improvements from the 1993 HEV challenge are discussed. Peak power used during acceleration is presented and then compared to the electric motor manufacturer ratings. Improvements in data acquisition methods for the 1995 HEV Challenge are recommended.
