ORION VII DIESEL-ELECTRIC HYBRID BUS
The Orion VII Diesel-Electric Hybrid transit bus
is specifically designed and well-suited for the traffic
demands of dense urban areas. It featues a series hybrid
electric system that is clean, efficient and compatible with
future powerplant technologies. It also provides reduced
emissions and increased fuel economy and meets rugged
transit durability requirements.
The BAE Systems HybridDrive® propulsion system
comprises of a diesel engine, a generator, a single electric
motor and an energy storage system that are all managed
by a computerized propulsion control system the “brain” of the operation.
The system features a regenerative braking system that
uses the drive motor to slow down the bus, effectively
turning the motor into a generator which recharges the
energy storage system. This saves energy and reduces
brake wear. The series hybrid design also eliminates the
need for a mechanical transmission reducing overhaul
costs - a major maintenance item on conventional buses.
The electric propulsion provides quicker acceleration to
help drivers more easily merge into heavy traffic. The
system also uses a smaller engine that contributes to
improved fuel economy.

Welcome aboard
Orion VII Diesel-Electric Hybrid Bus
1 The engine used in this bus is about half the
size of the engine used in a typical bus. It runs
cleaner on less fuel.
2 The generator supplies power to the electric
traction motor and the energy storage system.
3 The motor turns the drive wheels, just like in
a subway car. That means the bus accelerates
smoothly, with no sudden jerks. When the bus
slows down, the motor acts as a generator to
recapture energy for later use.
5 The propulsion control system directs the flow
of energy to the right place at the right time.
For example, when the bus needs to accelerate
quickly, it draws power from the batteries and
generator to drive the motor.

4 The energy storage system provides power
during acceleration. The lithium-ion batteries in
the HybriDrive propulsion system are lighter,
longer lasting, easier to maintain, less expensive,
and more efficient than competing alternatives.
