The unique design of the HybriDrive® series propulsion system pairs simple functionality with state-of-the-art electronics controls. The series configuration eliminates the mechanical connection between the primary power source (traditionally a diesel engine) and the wheels. The traditional combustion engine turns a generator and the power flows in series from the generator to power control electronics, to batteries, to electric traction motors, and finally then to the wheels. The Power Control System and the System Control Unit act as the brains of this fundamentally simple system design, optimizing energy flow to provide the highest level of propulsion efficiency and performance possible for the stop-and-go duty cycle of transit vehicles.
