Review of the Seine Aval Electric Vehicles Performance Trial

Electric Vehicles Performance Trial. 65 Renault-Nissan electric vehicles were driven in the Seine Aval ,  France area and 130 charging stations installed as part of SAVE (Seine Aval Véhicules Électriques), France’s biggest ever trial of all-electric mobility, made possible by a partnership between eight public  and private  entities.

Review of the Seine Aval Electric Vehicles Performance Trial

Recently the SAVE project participants met at the Renault production site in Flins to present a review of the project and the outlook for the future. The event was attended by Alain Schmitz, Chairman of the Yvelines departmental council and EPAMSA board and Philippe Hirtzman, representative for the national deployment of charging infrastructure with France’s Ministry for Industrial Renewal.

SAVE has met its objectives:

  • providing experience in the deployment of all types of charging infrastructure and the associated services,
  • contributing to knowledge on vehicle use and charging,
  • convincing customers involved in the project: two customers out of three ordered an electric vehicle following the trial.
  • With 40 participants, 150 test drivers and 65 electric vehicles,
  • SAVE attracted a broad base of support.

The SAVE trial involved many players, who thus became pioneers in electric mobility:

municipalities (Les Mureaux, Mantes la Jolie and Poissy) and companies (Carrefour, Total, Leclerc, Vinci Park, Intermarché) deployed charging infrastructure available to the public;

  • 40 participants (companies, municipalities and consumers) acquired charging stations and electric vehicles;
  • more than 150 drivers tested electric mobility in real conditions of use at the wheel of one of the electric vehicles involved in the trial: 20 Renault Fluence Z.E., 35 Renault Kangoo Z.E. and ten Nissan Leaf.

Seine Aval, on the cutting edge of electric mobility

Review of the Seine Aval Electric Vehicles Performance Trial

The Seine Aval area set the scene for a trial illustrating the possible future of all-electric mobility in France. The area, which was declared an OIN (operation of national interest) by the government, the Yvelines department and the municipalities, groups 51 towns and five inter-municipal bodies along the Seine River in the northern part of the Yvelines department outside Paris. The number and variety of charging stations here is the highest in France. A total of 130 charging stations, of which 48 open to the public, were installed as part of the trial. At the end of the project, 45 charging stations available to the public remained in operation and were upgraded with the latest developments. A further nine charging stations are scheduled for installation before the end of 2013. The stations are located in shopping centre car parks, on the street, in public car parks and in service stations. Wherever you are with your electric vehicle in Seine-Aval, you are never more than 15 km away from a charging station open to the public.

SAVE was an opportunity for all the participants to establish how best to install a complete ecosystem for electric mobility and to explore the related issues. All the technical and economic data necessary for deploying the various types of charging station were collected and analysed. The information gathered concerns:

  • the costs and problems related to installing charging stations,
  • interoperability between networks, stations and vehicles,
  • the need for energy management systems, and for tools and services used in the supervision and running of charging station networks.

This information will provide valuable input for developing a high-performance electric mobility industry alongside a range of products and services that closely reflect customer expectations.

More than 350,000 km covered, for 45.5 tonnes of CO2 avoided

With an average 25 km by day and by car, the electric vehicles were subject to intensive use, proving their ability to satisfy customers’ mobility requirements. Fifteen percent of customers even drove more than 60 km daily. Overall, the electric vehicles covered a distance of over 350,000 kilometres, for 45.5 tonnes of CO2 avoided (compared with an internal-combustion vehicle emitting an average 130g of CO2 / km).

But the carbon footprint of an electric vehicle does not stop with its use. The “well to wheel” assessment also includes the emissions from generating the electricity used to charge the vehicles. The calculations conducted during the trial indicate a “well to wheel” score of 16g of CO2 / km.

Convincing evidence for customers

Surveys conducted by two external institutes (ACME³ in June 2011 and LVMT* in April 2012) involving 47 users of electric vehicles taking part in the SAVE project confirmed the driveability of electric vehicles. Interviewees praised their smooth, crisp acceleration, and the restful ambience created by the onboard silence and absence of vibrations. The driving experience was described as calmer and more relaxed.

The procedure for charging the electric vehicles at the stations provided was also deemed satisfactory, with customers describing it is simple, easy to grasp and safe. Customers also appreciated being able to charge their vehicles in the workplace or at home, at an average cost of between and 2 per 100 km on their electricity bills.

A range extended by 25% with eco-driving techniques

During the project, Renault provided 46 eco-driving training courses for customers using the vehicles. The drivers trained saw vehicle range increase by an average 25% compared with their usual driving habits for roughly the same average speed during the journey (average variation in speed of 1% between “normal driving” and “eco-driving”).

A number of onboard features on electric vehicles also help the drivers to maintain vehicle range:

information on the dashboard and on R-Link, a connected, multimedia system, to help drivers manage their journey, range and charge more effectively,

  • the Eco button to increase range by up to 10%,
  • pre-conditioning of cabin temperature.
  • ZOE takes full advantage of the SAVE charging network

ZOE, the vehicle spearheading Renault’s electric strategy, is built at Flins-sur-Seine in theSeine Aval area. This all-electric hatch has a unique advantage in that it can be charged at any level of power between 3 and 43 kW, with a charging time of between 30 minutes and nine hours. It can therefore use the 22 kW supplied by 22 charging stations out of the 45 in Seine Aval and charge the battery to 80% in just one hour.

Like Nissan Leaf, ZOE can also be charged on the two fast charge stations (43 kW AC / 50 kW DC) deployed by total along the A13 motorway. In this case, it can charge the battery to 80% in just 30 minutes.
