ELECTRIC VEHICLE

ELECTRIC VEHICLES ARE RISING AS THE TOP ALTERNATIVE TO FOSSIL FUELS

At CIRCE, we stand firmly behind this alternative, so, over the years, we have built up a wealth of experience in R&D&I activities to encourage its deployment reliably and safely.

We have gone to great lengths to develop and validate an EV charging system offering slow, rapid and ultra-rapid charging that is compatible with all of the different connectors on the market. Our progress has been especially significant with wireless induction charging, which means new possibilities for this emerging sector. The new system enables both static charging (while the vehicle is still) and motion charging (while on the go), meaning the chance to install more charging points and reduce the weight and size of the batteries. This would entail a great opportunity in sectors such as freight and passenger transportation and in the deployment of electric vehicles outside cities.

Another major focus of our R&D&I work is the connection and integration of EVs in the grid. As well as minimizing the associated impact, we endeavour to improve grid stability, enable two-way flows and combine them with renewable energy sources and energy storage systems.

This can all be coordinated by means of the charging management programs designed and developed by CIRCE to control vehicle energy flows and renewable sources, which ensures the utmost efficiency.

TECHNOLOGICAL CAPABILITIES

  • Vehicle integration in the grid

We are studying how to connect electric vehicles to the grid (a concept coined as V2G) to ensure that connection is safe in both directions. We are also exploring the potential for these vehicles to act as stabilizing elements by providing energy or adapting the way they are charged.

  • Studying charging systems

We validate charging system operation for manufacturers, as well as investigating how to improve those systems with physical (conduction) and wireless (induction) connections.

Charger control centre in Malaga

 

CIRCE has developed a system for Endesa to manage the energy used in different electric vehicle chargers across the city of Malaga, which can also be used to manage other energy sources such as lighting and renewables.

Combined generation-storage charging point

 

This electric vehicle charging station located in Zaragoza features a renewable energy generation system powered by solar panels together with an energy storage system and three charging modes (slow, moderate and fast).

Ultra-rapid wireless charging for heavy electric vehicles

 

CIRCE has developed and validated a wireless energy transfer system capable of transmitting up to 300 kW of power that can be used to charge heavy electric vehicles such as buses and lorries at ultra-rapid speed.
