The company’s HybriDrive® Series system powers nearly 4,000 buses and has transported more than a billion passengers in cities across North America and in the United Kingdom including New York, San Francisco, Toronto, Ottawa, Houston, Seattle, London, and Oxford, U.K.
HybriDrive® Parallel was designed for the rugged
demands of the refuse, pick-up and delivery and
construction vocations. HybriDrive® Parallel benefits
from the stop-and-go nature of these vocations by
regenerating braking energy for significant fuel and brake
savings. The HybriDrive® Propulsion System is a hybrid
electric propulsion system which provides higher power
and torque capabilities than its competitors, and offers
superior drivability without compromising payload.
BAE Systems’ HybriDrive® Parallel System is comprised of an Energy
Storage System, Integrated Electronic Unit, and Integrated Drive
Unit all working together in the most efficient manner to provide your
vehicle with an average fuel savings of 30 percent* (average based
on vehicle track testing).
Energy Storage System (ESS):
Energy is captured during deceleration and stored into the battery
system; that stored energy is later used during acceleration for
fuel savings. Power from the ESS gives the vehicle a boost without
consuming more fuel. The Energy Storage System uses the
latest in technology—prismatic lithium-ion cells. This Lithium-ion
technology was chosen by BAE Systems because it’s lighter, longerlasting,
easier to maintain, less expensive, and more efficient than
competing battery alternatives.
The Integrated Drive Unit consists of a motor/generator and a hybrid
transmission. The IDU takes its direction from the IEU to blend the
engine and electric machine torque, maintaining the most efficient
engine speed during acceleration events. Once the vehicle is up to
speed and operating efficiently, the electrical power is phased out. As
the vehicle decelerates, the energy is captured via the generator and
stored in the ESS for the fore-mentioned use.
Save Fuel with Engine Off:
For additional fuel and emissions savings, the HybriDrive® system
has an efficient “engine stop/start” capability. When the vehicle is at
an idle position, the IEU signals the engine to power off to eliminate
this unnecessary fuel consumption.
John Peterson has a new article today. I would be interested if you post this on his comments section to see his response. He answers most of the posts if they are done soon after he writes his articles.
