Lithium Technology Supplies Li-Ion for Two Challenge X Vehicles, One a Plug-In Hybrid

Lithium Technology Corporation (LTC) announced that it will supply two of the vehicles in Challenge X —one of which is a plug-in hybrid—with its GAIA high-power lithium-ion polymer batteries.
Challenge X, sponsored by GM, is a three-year competition to re-engineer a GM Equinox crossover sport utility vehicle to minimize energy consumption, emissions, and greenhouse gases while maintaining or exceeding the vehicle's utility and performance. (Earlier post.)
Seventeen university teams are in the competition. Year 1, which ended in June 2005 (the years map to the academic year), focused on modeling, simulation, and testing of the vehicle powertrain and vehicle subsystems selected by each school.
A team from the University of Waterloo (Ontario, Canada) beat the competition from 16 US universities to take top place for Year 1 with their fuel-cell-powered vehicle design.
Years 2 and 3 will require teams to develop and integrate their advanced powertrain and subsystems into a donated GM Equinox. At the conclusion of each of these competition years, teams will come together to undergo extensive judging and evaluation. Events will encompass energy use and emissions goals, vehicle utility and performance, engineering, and K-12 Education Outreach.
LTC is supplying batteries to Penn State University and has received an order from University of California–Davis. In 2004, LTC supplied Penn State a different lithium-ion battery for Ford’s Future Truck competition in which Penn State finished second.
Trinity, Team Fate’s Challenge X vehicle is a plug-in hybrid that will include:
A UC Davis-modified Continuously Variable Transmission (CVT)
A turbo charger/generator to compress charge air for the engine and to use exhaust gases to recharge the battery pack
A 3kW hydrogen fuel cell for auxiliary systems such as power steering and air conditioning
Hydrogen injection into the combustion chamber to allow the engine to operate at higher temperatures and reduce NOx emissions.
The plug-in is designed to recharge overnight from a standard household socket, and will offer a 40 mile all-electric range.
LTC produces large-format lithium-ion polymer batteries under the GAIA brand name and trademark. The GAIA batteries offer an energy density of up to 140 Watt-hours per kilogram or 270 Watt-hours per liter, high current output, low weight and no memory effect.
