Project Motivation

High idle fuel burn in the target Euro6 transit bus application

Robustness and functionality limitationsof current solutions

Increasing base electrical power demand

High cost of traditional hybrid solutions

Technology Trends

– Stop/Start

– Engine Downsizing

10

– Accessory Electrification

– Smart Charging

FIRST

Scope – Durability, Cost, Performance

Durability over aggressive duty cycles and long vehicle lifetimes

– Engine, turbocharger and electronics development for durability

Low cost through system rightsizingand integration

– Subsystem development in Motor/Generator,Power Electronics, Energy Storage

– Cooling, packaging and controls integration

– Minimized changes to OEM vehicle interfaces

Additional functionality over conventionalstop/start systems

11

FIRST

Power Electronics development

Novel PE topologies, integration, packaging and control strategies

Advanced power module technologies and dynamicrating optimization

Prognostics and lifetimeprediction

High temperature electronics

Lower cost electronics package

FIRST

Project Benefits

Significant fuel consumption savings

Robustness to high-frequency stop/start over the life of a transit bus

Lower OEM integration cost and effort

Increased electrical power available for vehicle loads

Much lower cost than hybrid systems (target payback < 2 years),enabling widespread adoption

13

Benefits of APC support

APC funding and consortium

Connects UK partners that may not have otherwise collaborated

Funding brings “just below the line” activities “above the line”

Allows partners to leverage each others’ experience and expertise

For FIRST, the APC support has allowed usto tap into the expertise of our partners andbring these components together in anintegrated system in a way we had not donebefore.

Continuing Collaboration

Cummins Innovation Centre

Official Opening March 2012

A World Class Centre of Excellence inthe Research of Electrical MachineTechnology

A 5 year strategic alliance betweenCummins and The University ofNottingham

Led by Prof. Chris Gerada

Co-sponsored by The Royal Academyof Engineering

15

Continuing Collaboration

University involvement

Working with UoN provides industry with access to:

– world class expertise and facilities

– top talent

– additional engineering resources

– significant additional funding

This partnership has provided real value to Cummins

Congratulations to The University of Nottingham!
