2 The Danish Technological Institute was founded in 1906 For more than 100 years, DTI has ensured the translation of the latest knowledge and technology into real value for Danish businesses. Self-owned and not-for-profit More than 1,000 innovative employees, state of the art equipment and facilities as well as a strong global network. It is our mission to ensure that new knowledge and new technology are quickly translated into value for Danish businesses in the form of new or improved products, materials, processes, methodologies and forms of organisation.

11 DTI involvement in Electro Mobility 80 families tried an EV for 12 weeks in the demonstration project Try an EV with 15+8 EVs EV for EnergyFlexHouse demonstration project, where families living in an energy experimental house use an EV for transport Maritime Electromobility e.g. smart sharing of PV power on leisure boats DTI is in close cooperation with Danish Authorities DTI coordinates land/road transport activities in the national Transport Innovation Network DTI is member of The Danish Electric Vehicle Alliance The Danish Battery Society Several energy related standardization committees Smart Grid and Energy Storage related work groups

12 DTI involvement in Electro Mobility European - projects EasyBat EU FP7 R&D project 11 partners involved incl. Renault, Continental, Frauenhofer IPA and KEMA DTI battery degradation study: Battery specialist role, battery degradation analysis and modelling, smart storage modelling and benchmarking Green emotion EU FP7 Demonstration project with total budget of app. 40 mil. Euro 40 partners involved incl. Renault/Nissan, BMW, Daimler, Siemens, Bosch, IBM, SAP, Better Place, AREVA and a range of utilities covering 65% of the European energy supply DTI: Regional coordination, EV & battery testing, Safety and Training

13 * ) Not standard on all BESS plants A scaled down BESS test system at DTI with 65 kw / 0.9h LiFePO 4 is used for degradation and efficiency testing Battery Energy Storage Systems offer new support options for the Future Electric Grid Load levelling Time shifting demand and production Enable higher share of RE production Optimizing the RE production Buy electricity cheap, sell expensive Ancillary services Fast reacting demand/production response Primary Reserve response within seconds, typically needed only few minutes Reactive compensation Black Start assistance* ) Phase load balancing* ) 1.6 MW Vestas ESS Lem Kaer Denmark is partner in a BESS R&D project lead by DTI. Consists of two batteries: 0.4MW / 0.25h LiFePO 4 1.2MW / 0.25h Li 4 Ti 5 O 12

14 Selected Battery diagnostic and degradation activities at DTI: EASYBAT: Testing impact of EV fast charge on EV battery pack Green emotion: Field evaluation of battery packs in EVs ALPBES: Degradation at battery pack level (in vehicles and in lab) FESTAS: Assessment of different storage technologies for short time electric storage BESS: optimizing economy vs degradation on grid connected Battery ESS Electric Busses in Copenhagen. Battery life assessment. BATNOSTIC: Diagnostic system for EV battery assessment, without voiding any warranty on the EV via DC charge port. Test of battery suitability for African PV powered water supply (commercial test for Grundfos)
