Green emotion Demonstration Regions Cork Dublin Strasbourg Copenhagen/ Bornholm/Malmö Berlin Karlsruhe/Stuttgart Budapest In the Green emotion demo regions roughly 2,000 EVs were driving end of 2011 and more than 2,500 charging points were installed to supply electricity for them. This will increase to around 70,000 EVs and more than 80,000 charging posts in 2015. In total more than 380 Mio are spent in funded projects within these demo regions (plus private investments by Green emotion partners).

Interoperability National DSOs running pilot projects in Italy agreed on creating an unique contract ID linked to an energy contract to be signed with any energy vendor, in compliance with free market rules. E-mobility contracts can also be integrated with general purpose mobility cards, e.g. public transports card. Interoperability is already in place between Enel s and HERA s infrastructure. Pre-paid, billing and pay-per-use methods are enabled. 12
Grid-supporting opportunities of EVs As the EV market and particularly PHEV are about to enter in the rollout phase, ensuring the correct operation of the electrical system within technical standards is one of the main criteria which will have to be constantly fulfilled at all times in order to sustain a mass market. Electricity utilities industry is facing new challenges and opportunities due to the fact of recharging EVs and PHEVs through the local electricity grid, playing thus a critical role on the shape of the technology curve adoption for EVs. Furthermore, technological solutions must guarantee compliance with the innovative business scenarios that are being proposed by all stakeholders in the electro mobility field. Grid-supporting opportunities can be summarized with the load management or smart charging as seen from the user perspective. This means enabling an usage of the EV as a supporting load for grid needs, facilitating the DSO grid management issue at the start of the value chain and remunerating the end-user at the end of the value chain for the subsequent reduction of degrees of freedom.

Grid-supporting opportunities of EVs Smart charging field tests in Italy with 5 EVs launched in the market in 2012 Identification of two charging strategies to be tested against EV capabilities with regards to noise injection into the LV grid by modulating the current fed into the EV.

Grid-supporting opportunities of EVs Example: EV number 5 3.3 kw 2.5 kw Noise modulation is not correlated with fundamental modulation. Embedded EVs hardware is often not actively biased and noise performance worsten during smart charging.
Grid-supporting opportunities of Evs - Recommendations - OEMs should consider to improve embedded EV power electronics hardware to reduce noise impact in smart charging processes when the EV bias point is moved out of nominal power zone. Increase of noise injected in LV grid when EVs gets load-modulated could lead to grid reinforcements in massive scenario. This is completely in contrast to the original principle of deploying smart charging as a more effective solution than paving new copper wires in LV grid and may endanger the sustainability and reliability of smart charging value chain. Smart charging should lead to pricing incentives for the final customer. This means that charging fee could undergo local modulation according to the ancillary services provided to the DSO through the smart charging process involving the final customer and his contract with the EVSP.
