At a time when you can recharge your cell phone without connecting it to the charger with a cable, it is still necessary recharge electric cars connecting the car to charging point via a cable. In the not too distant future, surely the recharging of our cars will be done via wireless technologies. At the moment, numerous initiatives have already been launched to achieve this, one of them in Zaragoza.
The Zaragoza City Council and the CIRCE – Technological Center have presented an innovative technology of induction charging on the move and wireless. Without the need for cables, the car could be charged while driving.
Charge the electric car wirelessly and return power to the grid, also wirelessly
From car brands to the battery industry and automotive suppliers, there is no shortage of wireless charging pilot tests. It is something that would make the use of an electric car much easier. You arrive, park and the car starts charging, without having to remove a cable from the trunk or unravel the heavy cable from the electric station.
The CIRCE Technology Center has recently presented its wireless electric charging technology, developed within the framework of the European INCIT-EV project, with the help of the Zaragoza city council. This innovation will allow electric vehicles to be charged wirelessly, even on the move.
CIRCE’s proposal focuses on two aspects of electric mobility, urban mobility and long car journeys. One of the main achievements of this INCIT-EV project is the development of an inductive charging system specially designed as an opportunity charging system for electric taxis, for example. With a power of 50 kW at 85 kHz, would allow recovering up to 50 km of autonomy in just 10 minutes of charging.
A cooled transmitter coil is embedded in the floor, vehicles adapted for induction charging can thus be charged wirelessly and without risk of overheating by parking on it, which provides greater safety and easier charging.
Designed for car fleets, whether taxis or car sharing vehicles, the system also has the V2G function, for vehicle to grid, (from car to the network). Installed outside the Mobility City from Zaragoza.
This technology allows electric cars to not only recharge energy wirelessly, but also act as mobile energy storage units, exchanging electricity with buildings with a delivery power up to 25 kW. This solution contributes to balancing energy demand, supporting the stability of the electrical grid.
The second CIRCE project focuses on dynamic recharging, that is, recharging cars while they are moving. This system would allow vehicles to charge on the road “while traveling at speeds of up to 130 km/h,” say CIRCE. This system, based on the installation of a cable under the asphalt, is especially promising for long-distance trips.
The European INCIT-EV project, which has just come to an end after four years of work, has received funding of 15 million euros from the European Commission and has had a direct investment of almost three million euros in the city, which have allowed us to validate the viability of these technologies in real urban environments.
