New ORNL system provides hybrid electric autos with power to spare

Feb 04, 2010

An advancement in hybrid electric vehicle technology is providing powerful benefits beyond transportation.

Researchers at the Department of Energy's Oak Ridge National Laboratory have designed, fabricated and demonstrated a PHEV traction drive electronics system that provides significant mobile power generation and vehicle-to-grid support capabilities.

"The new technology eliminates the separate charging mechanism typically used in PHEVs, reducing both cost and volume under the hood," said Gui-Jia Su of ORNL's Power Electronics and Electric Machinery Research Center. "The PHEV's traction drive system is used to charge the battery, power the vehicle and enable its mobile energy source capabilities."

Providing more power than typical freestanding portable generators, the PHEV can be used in emergency situations such as power outages and roadside breakdowns or leisure occasions such as camping. Day-to-day, the PHEV can be used to power homes or businesses or supply power to the grid when power load is high, according to Su.

The charging system concept, which is market ready, could also be used to enhance the voltage stability of the grid by providing reactive power, Su said.

The Power Electronics and Electric Machinery Research Center is DOE's broad-based research center helping lead the nation's advancing shift from petroleum-powered to hybrid-electric and plug-in hybrid vehicles. The center's efforts directly support DOE's Vehicle Technologies Program and its goal to provide Americans with greater freedom of mobility and energy security while lowering costs and reducing impacts on the environment.

Useless vaporware article. For instance, is it more efficient? More KWH/lb of batteries?

good idea. I would love a car that can power my entire home when power is out, even do so automatically. Ask anyone in hurricane alley.

The hydrogen energy storage vehicles have that capability. I would also like to have my own portable home power source. Especially seeing as our grid is out of date and becomming less stable with each passing year.
