Outline

Goal and methodology

Proposed approach:

• To identify actual needs of European mobility through existing data

• To define and optimize the size of different solutions based on EREV fromuses’ specifications

• To build scenarios for forecasting EREV possible diffusion

• To evaluate the solutions (use + technology):

– Environmental aspects (LCA)

– Acceptability (sociological, economical, …)

– Recharging facilities

• 3

Main objective: to evaluate Extended Range Electric Vehicle as an optimizedsolution contributing to electromobility by addressing:

- Battery size (cost) according to the users expected range- Driver psychological assurance (guaranteed range)

– First survey with 61 participants – participant profile:• Potential early EV customers (applicants/participants in EV field trial)

• Sufficient practical experience with limited-range mobility

• Mobility profile: substantial daily distances (average: 111 km)

– Is an EREV concept generally accepted by potential EVcostumers?

Contribution to key dimensions

« technological strategies »:Provide inputs for manufacturers and decision makers about:

- EREV technology with different battery sizing- The expected performances (range, speed, LCA)

« Socio economic issues »:- EREV penetration scenario’s up to 2025- Use and user patterns, social acceptability of EREV

« Research and development »:- vehicle architecture: EREV power train designintegrated methodology directly linked to use data.

• 6 project meetings : 2 Paris, Chemnitz, Karlsruhe, Vienna, Lyon

• Expert workshop, Vienna June 2013

• Deliverables D1.1 and D1.2 available

• Advisory board constituted (Renault, BMW, Austrian FederalMinistry for Transport)
