Valence Technology and EnergyCS Plug-In Hybrid Vehicle Wins Awards at Tour de Sol


AUSTIN, Texas --(Business Wire)-- May 19, 2005 -- A concept plug-in hybrid vehicle (PHEV) developed by EnergyCS and Valence Technology, Inc. (Nasdaq:VLNC) has won the hybrid category in the Tour de Sol's Monte Carlo-style Rally, which ended May 14. Valence is a leader in the development and commercialization of Saphion(R) technology, the only safe, large-format Lithium-ion rechargeable battery technology.



Powered by Valence Technology's U-Charge(TM) Power System, the PHEV is a fully functional concept car based on a 2004 Toyota Prius. Modifications made by EnergyCS included incorporation of Valence's Saphion Lithium-ion battery technology in order to allow more zero-emission driving and better gas mileage.

In the Tour de Sol Monte Carlo-style Rally, in which there were 41 entrants, the vehicle won first place in the modified hybrid-vehicle category for fuel-efficiency and performance. On a 150-mile run, the EnergyCS-Valence PHEV achieved 102 miles per gallon (MPG) and used only nine kilowatt-hours of electricity to charge the Saphion lithium-ion batteries, which cost less than $1.00 to recharge. (For a commute of 50-60 miles between battery charges, the PHEV averages 125 or more MPG.)


The EnergyCS-Valence PHEV also won the Innovative Technology award in the Tour de Sol Championship for demonstrating a hybrid-vehicle architecture that can enable vehicles to reduce oil consumption and climate change emissions by replacing gasoline with clean, renewably produced electricity for its motive power.

About Tour de Sol
