This is the part 2 announcement after A123Systems CEO David Vieau's
Senate testimony Monday­calcars-news/­753.html. As of now, according
to the CalCars unofficial tally­where-phevs-are.html, Hymotion has delivered
11 Prius conversions. Before readers of this list start pestering the
company to get a PHEV, note that the current plan is to remain
focused on fleets until sometime in 2008.

The actual capacity of the Battery Range Extender Modules to provide the 40-mile electric range cited by Vieau is unclear. (Hymotion's current conversions are 5kWh.) Meanwhile, you can comment at the GreenCarCongress report:­2007/­05/­a123systems_acq.html

WATERTOWN, Mass.--(BUSINESS WIRE)--A123Systems today announced that it has completed the acquisition of Hymotion, Inc., the leading fabricator of aftermarket plug-in hybrid modules. These Battery Range Extender Modules (BREMs) can be easily installed in the spare tire well of most hybrid vehicles, enabling current production models to become Plug-in Hybrid Electric Vehicles (PHEVs) capable of achieving 100 or more miles per gallon. Converted PHEVs have the potential to reduce oil consumption by as much as 75 percent and CO2 emissions by up to 50 percent over today's internal combustion engine powered vehicles.

"With 5 million hybrids expected on the road by the end of 2010, we feel there is a significant opportunity for an interim aftermarket solution allowing consumers to experience the oil and CO2 reduction benefits that PHEV upgraded vehicles provide," said David Vieau, President and CEO.

The Hymotion acquisition provides A123Systems access to critical early IP on Plug-in Hybrid systems technology as well as valuable experience with engineering BREMs using A123Systems' Automotive Class Lithium Ion batteries. Terms were not disclosed.

"The fleet market has been an important testing ground for PHEVs" said Ricardo Bazzarella, Co-founder and President of Hymotion. "The Hymotion systems will continue to be available to the growing fleet market. Over the coming months we will work to reduce delivery times to fleets by standardizing packaging and in anticipation of having a consumer ready system for 2008 introduction."

"BREM technology is the near-term answer for plug-in hybrid vehicle technology and, thanks to recent joint contracts with NYSERDA and the South Coast AQMD, no company had nearly as much real-world data on engineering aftermarket modules with A123Systems' batteries as Hymotion," said Akos Toth, Co-Founder and Director of Engineering of Hymotion. "Joining forces with A123Systems enables us to more efficiently address demand for plug-in hybrid electric vehicles today."

The Hymotion team has a deep history in the alternative fuel and heavy duty vehicle segments, bringing critical integration and design experience to the group. This valuable experience includes work with OEMs such as Daimler-Chrysler and BMW, as well as heavy duty manufacturer Orion Bus Industries, and alternative fuels companies, Hydrogenics and Quantum Technologies.

The A123Systems Nanophosphate(tm) cells are next-generation lithium-ion batteries designed for exceptional power, safety and life. A123System's Automotive Class Lithium Ion cells have been optimized specifically for use in HEV and PHEV applications.
