Technologies being showcased include 42-volt and dual 14/42-volt architectures, a 36-volt absorbent glass mat (AGM) lead-acid battery, next-generation high-power generators, DC-to-DC converters, and an advanced LiPoTek lithium-polymer battery. Delphi's diverse offering in current and future power generation and storage technologies uniquely positions it for the anticipated demand by automakers for increased high-voltage electric power, according to Gary A. Cameron, chief engineer of Delphi's Energenix Center, an advanced energy engineering center in Kokomo, Ind., U.S.A. "Current luxury vehicles typically use up to 2.8 kW of power, but that's expected to double within the next five years," said Cameron. "Technologies like electric brakes and steering, electrically heated catalysts and electro- magnetic valve trains are all expected to require higher power, and this will lead to higher voltage electrical systems." In addition, higher-voltage electrical systems and the use of electrically driven accessories could improve fuel efficiency 5 to 10 percent, while wiring cable bulk could be reduced by half, he said. Fuel economy gains are achieved since all belt-driven systems -- HVAC, water pump, power steering -- could be electrically powered, relieving drag on the engine and reducing under-hood space requirements. Wiring bulk is reduced because higher-voltage systems lower current, enabling smaller wiring. In addition, other functions can be performed with higher-voltage systems such as saving fuel by turning the engine off at idle and then quickly restarting when the vehicle needs to launch from the traffic light (commonly called stop and go). In the traditional 12-volt architecture, emerging electro-mechanical systems -- such as electric steering -- would become "electricity hogs" requiring larger-diameter wiring that adds weight and cost, he observed. A proposed industry standard of 42 volts has automakers and suppliers looking at new ways to use the higher power to redesign systems on future vehicles. Many in the industry favor the dual-voltage system that includes both 14- and 42-volt circuits. Traditional low-voltage devices such as lamps and radios could run off the 14-volt system while the 42-volt system would power those applications that need and/or run more efficiently with higher power. "Delphi has developed improved dual 14/42-volt and 42-volt architectures that will offer vehicle builders the ability to provide an array of advanced electrical/electronic devices that are impractical with today's 14-volt systems," said Cameron. "This includes electrically driven accessories and systems that the major manufacturers currently offer or want to develop for fuel economy. In addition, there are many electrical customer features requiring higher and more efficient electrical power," he added. "Delphi has a unique ability to provide both power generation and energy storage. We have developed an advanced 42-volt system that will be a practical bridge to the hybrid powertrains of the future," Cameron continued. [...]
