  The installation of electric vehicle charging stations (EVCS) will be
essential to promote the acceptance by the users of electric vehicles (EVs).
However, if EVCS are exclusively supplied by the grid, negative impacts on its
stability together with possible CO2 emission increases could be produced.
Introduction of hybrid renewable energy systems (HRES) for EVCS can cope with
both drawbacks by reducing the load on the grid and generating clean
electricity. This paper develops a methodology based on a weighted
multicriteria process to design the most suitable configuration for HRES in
EVCS. This methodology determines the local renewable resources and the EVCS
electricity demand. Then, taking into account environmental, economic and
technical aspects, it deduces the most adequate HRES design for the EVCS.
Besides, an experimental stage to validate the design deduced from the
multicriteria process is included. Therefore, the final design for the HRES in
EVCS is supported not only by a complete numerical evaluation, but also by an
experimental verification of the demand being fully covered. Methodology
application to Valencia (Spain) proves that an off-grid HRES with solar PV,
wind resources and batteries support would be the most suitable configuration
for the system. This solution was also experimentally verified.
