Subaru to Evaluate Quick Charge Electric Car with New York Power Authority
• 50-mile Charge Costs Less Than $2 Dollars
• 80-Percent Re-Charge in 15 Minutes
Subaru today announced that it would begin evaluating its R1e electric vehicle (EV) in the United States this summer. The Subaru R1e will be on display at the New York International Auto Show, from March 21-30 at the Jacob Javits Convention Center.
Based on the Subaru R1 minicar sold in Japan, the R1e was developed by Subaru in partnership with the Tokyo Electric Power Company, Inc. (TEPCO). The utility has been testing a fleet of R1e electric cars since 2006. As part of a U.S. test program, two of the Subaru R1e electric cars will join the New York Power Authority (NYPA) fleet (NYPA is USA's largest state-owned electric utility).
The Subaru R1e employs state-of-the-art, fast-charge lithium ion battery technology that eliminates typical lithium ion battery issues of charge memory loss, allowing partial charges and quick charges that do not decrease battery life. The two-seat Subaru R1e is capable of driving at speeds up to 65 mph with a range of up to 50 miles, making it an ideal urban commuter. The Subaru R1e can be "quick-charged" to 80 percent capacity in only 15 minutes using quick-charge technology. The vehicle can be fully charged overnight (eight hours) while connected to a standard household electrical outlet. The R1e uses an AC permanent magnet synchronized motor producing 40 kW.
There are currently 40 Subaru R1e vehicles in use and Subaru parent Fuji Heavy Industries will place an additional 100 electric vehicles for test marketing in Japan in 2009. Subaru is focusing on the development of new battery technology for future power train applications. Compared with nickel metal hydride or nickel-hydrogen battery technology, lithium-ion battery technology offers a number of advantages, among them easier packaging, higher power density and better cooling for longer life.
Service life for the high-density lithium-ion battery is estimated at 10 years and 100,000 miles, another environmental benefit. The battery pack is also designed to be easily recycled. The laminated battery packs are flat, rather than cylindrical, offering EV manufacturers wide latitude in vehicle design and packaging. The battery's basic design and composition consist of laminate, manganese, and lithium ion.
Subaru of America, Inc. is a wholly owned subsidiary of Fuji Heavy Industries Ltd. of Japan.
