| 摘要： | This project involved laboratory and road testing of the Horizon(registered) advanced lead acid batteries produced by Electrosource, Inc. A variety of electric vehicles in the fleet operated by the Sacramento Municipal Utility District and McClellan Air Force Base were used for road tests. The project was sponsored by the Defense Advanced Research Projects Agency under RA 93-23 entitled Electric Vehicle Technology and Infrastructure. The Horizon(registered) battery is a valve regulated, or sealed, lead acid battery produced in a variety of sizes and performance levels. During the project, several design and process improvements on the Horizon(registered) battery resulted in a production battery with a specific energy approaching 45 watt-hours per kilogram (Whr/kg) capable of delivering a peak current of 450 amps. The 12 volt, 95 amp-hour (Ahr) Horizon(registered) battery, model number 12N95, was placed into service in seven (7) test vehicles, including sedans, prototype lightweight electric vehicles, and passenger vans. Over 20,000 miles have been driven to date on vehicles powered by the Horizon(registered) battery. Road test results indicate that when the battery pack is used with a compatible charger and charge management system, noticeably improved acceleration characteristics are evident, and the vehicles provide a useful range almost 20%greater than with conventional lead-acid batteries. |
