1. CenexCentre of excellence for low carbon and fuel cell technologies Low emission vehicle demonstration October 7th 2010

2. Introduction to Cenex • Running projects and programmes focused on accelerating the deployment of low carbon vehicles • Managing low carbon vehicle procurement • Overseeing fleet demonstration activities to trial and test new low carbon vehicles and fuels • Delivering fleet carbon reduction • Disseminating low carbon developments to key stakeholders • Cenex clients include:

3.

4. Introduction to the trial – 2009/2010 • Four smart ‘fortwo’ electric vehicles were deployed in the North East of England, aims: • Increase exposure of electric vehicles • Collect data for analysis and dissemination • Four regional vehicle hubs were created for deployment to • Eight public sector fleets • Two private sector fleets • Three public drive events • Users selected through prequalification questionnaire

5. Trial - Data collection systems • Qualitative data • Fleet users questionnaire • Fleet mangers questionnaire • Public drive events questionnaire • Quantitative data • Telemetry system installed

6. Trial – Fleet user assessment questionnaire • 10 Public and Private fleets, good return rate • Fleet users rate EV performance as good (=4) • Highest score in environmental factors • 58 % of fleet users felt more positive about EV’s after participating in the trial • 83% of fleet users in their 20s had positive opinion shift

7. Trial - Charging assessment • Charging at work dominated charging events • Four councils had access to recharging posts • Users rate EV charging experience as good (=4) and charging easy and intuitive • Private fleets rate availability and safety lower than public fleets (no access to dedicated infrastructure?)

8. Trial – Recharging behavior • Charge management assessment shows the vehicle charging was generally well managed, but some room for improvement exists • 95% of users state vehicles always or normally have sufficient charge for the intended journey • But 34% of users thought there wasn’t enough charge on occasion • Private fleets were less vigilant at opportunity charging and had more instances of users being concerned about range

9. Trial - Fleet manager’s assessment • Motivation for trial involvement • To meet the organisation’s green aspirations • Good opportunity to trial EVs • Hope to incorporate EVs into future operations • Main barriers to incorporating EVs into your fleet? • Range and purchase price • Lack of infrastructure was not perceived as a barrier to fleet integration • Opinion change of electric vehicles • 88% of fleet managers felt more positive about incorporating electric vehicle into their fleet after trial participation • Similar trend to fleet users Only 1 in 6 fleet managers concerned about ‘limited public recharging infrastructure’ 50% of organisations installed their own charging posts for the trial

10. Trial - Range and CO2 • Data logged over 100 journeys Jan/Feb 2010 • Average range 72.4 km emitting 82.3 gCO2/km • Range varied +/- 40 km depending on operating conditions

11. Trial - Regeneration performance • Consumed 2.13 kWh, regenerated 0.210 kWh (9%) • Average regeneration rate for all logged journeys was 11.3% • Regeneration performance recovery varied from 4 to 29% Larger regeneration available, representative of coast down or braking after higher speed operation Frequent stop-starts representative of congested traffic flow allowing numerous small regeneration events Battery SoC reduces significantly during prolonged high power operations.

12. Trial - Range anxiety 55 % of journeys were less than 5 km. The average journey length was 4.8 km • 4.8 km average journey length • 100% of journeys are achievable with a starting charge of 50% • Users begin to modify their driving style at journey end State of Charge (SoC) reduces to 50% The maximum journey length is 17.8 km. This represents only 46% of the minimum extrapolated range observed during thetrial, or 25% of the average range 93 percent of journeys are started with above 50% SoC Driving efficiency improves for journeys ending at a low SoC

13. Trial next steps – 2010/2011 • Trial continues this FY • Focus on long residency case studies with private fleets • New Generation Li-Ion vehicles (iMIEV and smart fortwo) • Technical research on vehicle behaviour • Traffic interactions • Regeneration • Battery health • Laboratory and test track analysis • Dissemination event Nov 2010 • Full results April 2011

19. Fleet carbon reduction tool • A new fleet simulation package built to provide accurate predictions of the carbon and cost impact of introducing low carbon vehicles • Cost-effective answers to questions like these • What types of low carbon vehicles are out there? • How will these vehicles perform in my application, which types are appropriate for my fleet, and what are the limitations? • What is the whole life cost of low carbon vehicles, and by how much will they really reduce my carbon emissions?

20. Fleet carbon reduction tool • Delivering an accurate estimation of the carbon reduction and economic impact of different transport fuels and technology options, modelling • Vehicles • Powertrains • Duty cycles. • Current fleet is characterised and input into the simulation to ensure baseline accuracy, then outcomes of low carbon vehicle deployment scenarios are examined. • Tool outputs have been validated against the large amounts of real-world data collected by Cenex during its own vehicle trials. • Tool operated by Cenex engineers experienced in low carbon vehicles.
