The project is organized in two parts. In the first stage it has been successfully concluded the development and the experimental validation of a charging station with 50 kW DC according to the Japanese connection protocol CHAdeMO. The charging station, that has been developed by the researchers of GH Electrotermia with the support of the Universidad de Valencia, the Universidad Politécnica de Valencia and the company Herga, integrates innovative services of the Information and Communication Technology (ICT), such as an advanced system for the location of charging points, their availability in real time, remote payment system by user ID and information via mobile phone about the charging process.
In addition, in this first stage, the company Saft Baterías, in collaboration with the Instituto Tecnológico de la Energía (ITE), and the batteries laboratory of the Universidad de Oviedo are analyzing the repercussions of this king of charging on the reliability and durability of Li-Ion batteries of the vehicle, since one of the critical points for the real expansion of the electric vehicle is batteries reliability, affected by quick charges due to the increase in temperature that they experience during this process.
In the second stage of the project it will be developed a bidirectional charging system with a supporting battery aimed at a smaller impact on the electricity grid and at its leveling in the peak hour thanks to the bidirectionality of the system. The system has been named B2G (Battery to Grid) in analogy with the system V2G (Vehicle to Grid) and the main idea is a smaller demand of the grid electricity during the charging process of the vehicle, thanks to supporting batteries that will supply part of the energy to the vehicle.
The Project SURTIDOR, funded by the Ministry of Industry, Tourism and Trade within the Plan Avanza and headed by the Valencian company GH ELECTROTERMIA S.A., aims at the development of ultra-fast charging station for electric vehicles, the analysis of the impact of these stations on the current electrical infrastructure of electricity distribution and their validation on current electric vehicles.
The project included the research on all elements involved in the charging process: electric vehicle battery, charging procedures, interaction with the electric vehicle, ultra-fast charging converter, energy storage system with bidirectional converter, smart management platform (measures and payment, geo-location, remote management, integration into the supply grid).
The project has been co-funded by the Ministry of Industry, Tourism and Trade, within the Spanish National Plan for Scientific and Technological research, development and Innovation 2008-2011. Project reference number is TSI-020302-2010-0127.
