Parallel Hybrid Drive Train

• Sized for full all-electric mobility

• No mechanical coupling of engine to road enables

maximum control over engine operation

• Applicable for fuel cell or battery powered vehicles

• Ideal for urban Transit Buses

• Sized for desired braking energy capture

• Engine still mechanically coupled to road;

enables higher efficiency at highway speeds

• Scalable for a wide range of duty cycles

• Ideal for trucks

Your optimum Power Management System supplier in a rapidly changing world

Issues to Consider

• Benefits clear – less fuel consumption, reduce emissions, smoother

ride. Do they outweigh the challenges?

• Costs: - are fuel cost savings over the lifecycle of the bus enough to

achieve lower overall capital cost?

• Subsidies: - is subsidy policy appropriate, or targeted on inappropriate

objectives? Are subsidies sufficiently attractive?

• Technology: - is current policy achieving desired results?

- is technology reliable/robust enough for demands?

- what is the most appropriate system to use?

- are batteries sufficiently reliable?
