Delphi Announces ENERGEN(TM) Energy Management Systems

Delphi's ENERGEN(TM) Creates New Energy Sources While Protecting Environment

    TROY, Mich., Feb. 23 --  Delphi Automotive Systems
ENERGEN(TM) will help OEMs address two of the automotive industry's most
pressing energy issues -- the need to address worldwide concern over global
warming, and the need to create a power source to allow for the expansion of
vehicle electrical/electronic content.
    Delphi's ENERGEN concept, shown today at the 1998 SAE International
Congress and Exposition in Detroit, is being developed by the company's Energy
& Engine Management Systems and Delco Electronics Systems divisions.
    ENERGEN is a family of energy management systems that make additional
electrical power available onboard a vehicle to support the advanced
electrical and electronic features of next-century vehicles.
    With the flexibility of multiple voltage capabilities, including the
standard 12-volt system, voltages can be optimized over a wide range to
efficiently power a multitude of functions.
    For example, vehicles of the future may need additional electrical power
for:  electronic throttle control, steering, braking and suspension; climate
control and heated seats and windshields; collision avoidance systems; vehicle
security; satellite communications including personal computer, Internet and
video conferencing capabilities; and ever-more-sophisticated engine management
systems.
    "With advanced energy management, you could use your vehicle to light and
heat or cool your home, to run an electric lawnmower, or to cook supper on
your vehicle's microwave oven," said Donald L. Runkle, vice president and
general manager of Delphi Energy & Engine Management Systems and champion of
Delphi's Engineering Task Team.
    ENERGEN systems under development involve increasing electrification and
integration of the ENERGEN system with the powertrain.   For example, in a
hybrid vehicle configuration, ENERGEN couples an integrated motor/generator, a
high-voltage battery system, and high-power electronics to substantially
improve fuel economy and reduce emissions.
    "ENERGEN opens an intriguing set of possibilities," Runkle said.  "You
could use the system as a performance booster, matched with a conventional
drivetrain.  Or, you could mate it with a small diesel engine to focus on
greater fuel economy.
    "You could even use it in a pure electric mode in a ZEV (Zero-Emission
Vehicle) zone, then switch to hybrid power away from a city to take advantage
of the long range provided by fossil fuels," he said.
    ENERGEN is one of several energy management systems Delphi is developing
to help protect the environment, according to Runkle.
    "New developments in alternative energy sources and hybrid propulsion, for
example, promise dramatic improvements in fuel economy," he said.  "That's a
critical element in the reduction of carbon dioxide (CO2) exhaust emissions,"
Runkle said.
    "At the same time, energy management can provide the power for vehicle
functions still in the daydream stage," he said.
    Delphi Automotive Systems, with headquarters in Troy, Mich., USA, is the
world's most diversified supplier of automotive components and systems.  With
the recent integration of Delphi Delco Electronics Systems, Delphi operates
208 manufacturing facilities, 46 ventures and 27 technical centers in 36
countries.  Regional headquarters are located in Paris, Tokyo and Sao Paulo.
