Our technological expertise

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.

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.
