Spanish electricity company Endesa has unveiled a new wireless charging technology for electric vehicles in Spain.

Developed jointly with research centre Fundación CIRCE, the new high-power charging system allows electric batteries to be 80% charged in around 15 minutes.

The system, which works with inductive technology, requires the electric vehicle with a receiver beneath to be positioned on a ground-level charging platform.

When the car is detected, the system connects wirelessly, transfers the energy charge and stops automatically once the service conditions are met.

Cars need not be exactly positioned above the transmitter coil as the charger can detect the vehicle even if it is 30% away from the alignment.

The new charging service has been developed to transfer 50Kw of power. Charges made at these high power levels are considered to be safe, with emissions kept under the permitted limits.

"The new high-power charging system allows electric batteries to be 80% charged in around 15 minutes."

The charging device can be installed easily in any location, offering protection against vandalism and unfavourable weather conditions. Drivers do not have to leave their electric vehicles at the time of charging.

Once the base technology introduced in Spain has been developed, the company expects it will be included and adapted for different motionless charging needs, such as at bus stops or terminals, for trucks or service vehicles at specified areas and private cars at service stations.

It will be easier to increase power to adapt to different charging needs in the future with the developed system.

Endesa along with Italian power company Enel, is taking part in various work groups under the Unplugged project, a European initiative to develop wireless charging.

As a part of this project, Endesa and the Fundación Circe are leading the work group to build an inductive fast charge point.
