Evaluation of Electric Vehicles as an Alternative for Work Trip and ...

contribute to a favorable reputation for the partnering organizations
that made this project possible. The five (5) longest drives in 1998
occurred during the ATdS and were accomplished within the voltage-cutoff
guideline. The good showing was indicative that this year the ALAB car
would run better that in previous years.
Following the 1998 ATdS, the ALAB car was running well and data
gathering resumed from daily commuting and work trips in the ALAB car.
Data were recorded from instrument and battery-management system output
daily in accordance with our research work plan requirements.
Periodically, information was posted to the project Web Site (see
Appendix B).

FIGURE 7 Constant three percent grade on 1.4-mile (2.2-km)
section of I-384 slowed the ALAB car from 65 mph to
57 mph at full power
During this period the vehicle was used for commuting and work
trips. One routine work trip is from the Hartford area to the
University of Connecticut (UConn). A common route for a portion of this
trip is Interstate I-384. The speed limit in this 8.5-mile Interstate
