Hella Energy Management Systems Increase Car Features, Fuel
DETROIT, MI. October 21, 2008: Hella KGaA Hueck & Co., a global tier-one automotive supplier,
that American consumers expect their fuel-efficient automobiles to be
more than small “econo boxes.”
Hella is showcasing several energy management technologies at
Convergence 2008, Oct. 20-22 at Detroit’s
Center, that address the needs of automakers and consumers alike.
With Hella’s energy management portfolio,
automakers can offer higher feature content in smaller vehicles,
increasing the size of the battery and at the same time reduce fuel
“The spike in fuel prices during 2008
many American car buyers to downsize from their larger vehicles, but
consumer preference surveys have shown that people want more
fuel-efficient cars, not just smaller ones,”
noted Dr. Martin Fischer, president of Hella Corporate Center USA.
auto manufacturers need to avoid the trap of thinking that new small
buyers are willing to forfeit the features they have become
to in larger vehicles.
“Small cars don’t
have to have fewer features to save fuel. With the proper energy
management devices, smaller vehicles can have much of the luxury
equipment that American consumers want and manufacturers can
The Hella executives noted that by the middle of the next decade, due
federal mandates, the auto industry will be required to make vehicles
averaging 31 percent better fuel economy than today’s

to reduce carbon dioxide (CO2) emissions.
years, Hella has worked intensively with its customers and partners
develop strategies for improving fuel economy.
Many of Hella’s energy management
technologies already are on vehicles in Europe and include adaptive
cruise control, automatic start-stop controls, battery sensors,
stabilizers, air-conditioning sensors and lighting systems. No single
product will provide “the solution,”
according to Fischer. Instead, the answer is integrating systems that
will in turn lead to overall improvements in fuel economy.
Taking a holistic approach to energy management, Hella’s
portfolio of fuel-efficient and CO2-reducing
technologies on display at Convergence 2008 includes:
Adaptive Cruise Control (ACC): Now on the Chrysler 300, ACC
detects the relative speed and distance to vehicles in front and
automatically adjusts the car’s speed.
device has trimmed fuel consumption and CO2
emissions by one percent.
Automatic Start-Stop Control: A fuel-saving device
in hybrid vehicles, the automatic start-stop control turns off an
engine during stops at traffic lights or traffic jams and quickly
restarts the motor when it’s time to
In normal city-highway driving, fuel consumption is reduced by
five percent. In city driving, up to a 20 percent boost in fuel
economy is possible. Primary enablers for the system include a
Condition Sensor and Medium Power Voltage Stabilizer.
stabilizer is a direct current converter that protects the
sensitive electronic systems from powering down during an engine
Demand-Driven Fuel Pumps: Operating as demanded by engine
requirements, these fuel pumps reduce electrical-system load by up
100 watts and save 0.5 grams of CO2 per
Electric Vacuum Pumps: More efficient than conventional
belt-driven pumps, this device provides a vacuum boost during the
vehicle’s warm-up phase. It switches off
soon as the engine reaches its operating temperature, reducing
emissions by 4.0 to 6.4 grams per mile.
Electronic Pedal Sensors: Detecting driver intentions, the
electronic pedal sensor can help cut CO2
emissions by 16 to 24 grams per mile.
High Intensity Discharge (HID) Light Modules: Using an arc
between two electrodes rather than a filament to create light, HID
modules have the power rating of a conventional 38-watt bulb, but
actually provide more light than a 55-watt bulb. HID lighting
consume less energy, trimming CO2
They are mercury free and contribute to sustainable environmental
Fuel-Quality Sensor: Ensuring that gasoline or diesel fuel
injected only as is needed to start the engine, this sensor can

Intelligent Battery Sensor (IBS): The size of a postage
the sensor is a key energy management contributor. It tracks energy
output from numerous electrical devices to prevent total battery
discharge and optimize the charging process. IBS helps reduce
consumption and saves approximately 2.4 grams of CO2
per mile. IBS and Hella’s Voltage
Stabilizers were integrated with other systems on the BMW 1
in Europe, boosting the car’s fuel
up to 24 percent, while trimming emissions by 21 percent.
LED Daytime Running Lights (DRLs): DRLs are designed
increase the visibility of a vehicle when driving during daylight
hours. LED (light emitting diode) DRLs provide an energy savings of
percent compared to conventional lighting and thus are helpful in
reducing vehicle CO2 emissions.
Oil Quality Sensor: Called the PULS (packaged ultrasonic
sensor), Hella’s second-generation oil
sensor is standard equipment on a number of European vehicles. It
helps extend oil life, allowing for a reduction of about 4 grams of
per mile, while permitting automakers to develop effective
engine-management systems to improve fuel efficiency.
Xenon Headlamps: Equipping a vehicle with a combination of
35-watt Xenon headlights and halogen brake lights can achieve
savings of up to 25 percent.
“By model years 2011 through 2015, cars
achieve 35.7 miles per gallon while the standard for trucks rises to
28.6 mpg,” Fischer said. “The
good news is that Hella has proven products that can boost fuel
