Inductive charging is already closer to electric vehicle users thanks to the UNPLUGGED project

Contributed by: CIRCE

UNPLUGGED has investigated how the use of this inductive charging in urban environments improves the convenience and sustainability of electric mobility, developing a flexible quick wireless charging system so that the battery of an electric vehicle, can be charged without needing to leave the car. The project has been a European initiative supported by the Seventh Framework Programme (FP7) where 17 partners have been involved.
The European project UNPLUGGED has come to an end having achieved the development and construction of an inductive quick charging station for electric vehicles. This project is a European initiative that in the past two years and a half has developed the quick wireless charging of electric vehicles and has investigated how the use of this inductive charging in urban environments improves the convenience and sustainability of electric mobility.

The primary objective of the Unplugged project was to build a flexible inductive charging station which enables to charge electric vehicles up to 50 kW, which is the master key for instance when providing a full integration of electric vehicles in the urban road system (dynamic or en-route induction). UNPLUGGED has fulfilled these objectives examining in detail the technical feasibility, practical problems, interoperability, perception of the user and socioeconomic impact of inductive charging.

The project finished by the end of March at CIRCE's headquarters in Zaragoza (Spain). The event consisted on the results presentation, workshops with technical and administrative stakeholders, and included a real demonstration of this charging system for two different power needs in charging: a light vehicle (3.7kW) and a van (50kW), achieving flexibility of charge in addition to enabling smart communication between the vehicle and the network, are in line with the latest inductive charging standards and taking into account interoperability.

In addition to its use in roads, this charging solution will allow to offer flexible charging services based on customer needs, for instance in public car parks on the street:
• Slow charging (3.7kW) at night: 'I park the car at 8 pm, pick it up at 8 am and it is fully charged'.
• Fast charge (up to 50 kW) at daytime: 'I have to charge my EV, I use the 20 minutes needed to go shopping while the car is charging'.
• It reduces maintenance costs related to vandalism of traditional conductive charging systems.
• Opportunity of new business models for public transport, for instance taxis or buses or at shopping centres, hotels, etc, for instance, where the client leaves the EV charging during his/her stay.

The UNPLUGGED consortium is managed by FKA and ENIDE and coordinates the efforts of the main agents of the sector: automotive (such as Volvo, Centro Ricerche Fiat, Hella or Continental), energy (ENEL and ENDESA) and other key research centres, such as the CIRCE Foundation, with a total of 17 partners.
