The Hymotion plug-in battery pack uses lithium ion cells supplied by A123 and is designed to fit in the same package size as the OEM nickel metal hydride pack. The converted vehicles have an electric-only range of about 35 miles. As some of the early production Priuses start to reach the end of the battery lifespan over the next few years, HyMotion hopes to tap into the replacement market with their plug-in kits. Hymotion is hoping that aftermarket, as well is increased interest from governments, utilities and other fleets, allows them to grow deliveries from a few dozen this year to as many as 2,000 in 2008.
