LEADING TOWARDS A NEWBATTERY ECOSYSTEM

SCROLL TO DISCOVER

Why Batteries?

Energy Storage is changing our lives. Now we have the opportunity to revolutionize our industry, our society and our environment.

Facilitating the penetration of renewable energy sources and a more efficient use of electricity, i.e. via smart grids solutions with battery storage.

Promoting electromobility at all levels thanks to efficient, safe and affordable batteries.

Generating new bussiness, jobs and wealth as a result of intensive research, transference of technology and entrepreneurship.

Center of reference in a key technology for the future

DELIVERING VALUE
TO THE EUROPEAN INDUSTRY

At CIDETEC Energy Storage we believe technology transfer to the industry is the culmination of the ideation and R+D process.

MEET OUR TEAM
OUR TECHNOLOGICAL OFFER

From powder to power


Our specialization covers from powder to power, which means from primary electrode materials to full size, application ready battery packs. As our motto goes, we aim to bridge the gap between research and industry. This means that we concentrate in knowledge generation and how to translate it into technology that can be smoothly transferred to the industry.

BATTERY MANUFACTURING

After the basic development is archieved at lab level, the next step in our process is going an step forward through our fully equiped Battery Manufacturing Pilot Line.

First, the scale up mixing, coating and calendering processes is performed according to industry state of the art techniques to produce continuous, double side coated professional electrodes.

In a second step we assemble fully performant battery cells up to 40Ah for validation and assessment of materials and processes.

Energy management system

APPLICATIONS

Integration of energy storage systems into (heavy) vehicles.

 

At CIDETEC Energy Storage we develop full size battery pack solutions for electric buses and other heavy duty applications.

Our assignment corees from inicial cell choice and validation to full battery pack design, including BMS, communications and safety.

We build fully operative prototipes in close contact with our customer, so that at the end of the process we smoothly transfer a pack design already co-developed and validated together. Since the first vehicles started real operation at our home city Donostia-San Sebastian, many others units from several eBus models are hitting the European roads.
