The number of electric vehicles is increasing exponentially and there is a high need for charging infrastructure. Furthermore, climate change motivates for the integration of renewable energy. Therefore, a DC-coupled charging station connected to photovoltaic and a stationary battery system is being researched for a workplace environment. The component sizes are economically optimized for 20 charging points. The influence of a simple photovoltaic persistence forecast on the marginal charging tariff and the self-sufficiency is analysed depending on the component sizes. It is shown, that the positive influence of implementing a self-consumption maximizing charging strategy outweighs the monetary losses of forecasting inaccuracies. The decrease in self-sufficiency compared to a perfect PV forecast is 1 percentage point versus an increase of 25 percentage points compared to uncontrolled charging. Although systems without a battery are more economic, it is also shown, that systems with a battery can become economic for larger PV sizes.

Reducing emissions from the transportation sector is one of the fastest ways to combat climate change. 

Electrifying mobility is propelling new technologies, empowering consumers to take concrete action and is demanding politicians to take swift and concrete action.

What will the future of electric mobility look like? And what are the biggest challenges for realizing zero emission transport on the road, at sea and in the air? 

The 13th-15th June, people from all over the world will travel to Oslo, the world’s leading player in electric transport, to participate in this year’s biggest EV conference.
