This report is concerned with the development of procedures for testing of hybrid/electric vehicles to determine their energy consumption and emissions characteristics. Special emphasis is given to hybrid vehicles, which can be operated above some minimum battery state-of-charge in an all-electric mode for all types of driving (city and highway). When the all-electric range of these vehicles is exceeded, the vehicles are operated in the hybrid mode, in which an engine/generator is turned on to generate electricity on-board the vehicle. Key issues in testing hybrid vehicles are identified and discussed. These issues include the test cycles to be used, the instrumentation required, the effect of battery state-of-charge and control strategy in the hybrid mode on the need for repeated test cycles, and the data to be collected and how that data from repeated cycles is interpreted to determine the vehicle energy consumption and emissions characteristics.
