Abstract [en]

Using the energy of the sun to power our vehicles has always been a wish, With today's technology this is possible. In order to charge an electric car with sun power you need solar cells, inverters and charging place. In addition to this, some type of energy storage can be useful, this because it helps getting a larger proportion of self-employed sun power, for example. Lithium-ion battery. With this technology, anyone who invests in an above- mentioned solar cell plant can reducing the electricity they buying. This also benefits the electric grid by reducing the load, and this will become increasingly important in the future as more and more people are choosing to drive electric cars which will increase the load on the grid.

The purpose is to gain knowledge of current research and development work in the field of charging of vehicles with solar energy technology. To investigate the technology's possibilities and limitations in society with a focus on increasing the use of renewable energy. Earn knowledge in how the technology should be dimensioned and designed to achieve optimum performance while being sustainable and safe. The solar plant should have the capacity to charge 30 electric vehicles per day and be able to charge 10 vehicles with fast charging and 20 vehicles with normal charge. Development of an Excell sheet in order to be able to simulate different operating conditions.

The results show that a solar plant that can charge 30 electric vehicles per day and be able to accumulate electricity for charging 30 vehicles requires a large surface area for the solar cells (approx. 2,780 m2). The installed power is around 444.8 kWp. For the accumulation, a large lithium ion battery of 1,800 kWh is required, with a weight of about 12 tons. In addition, inverters are required to convert the solar DC to AC. It also requires a place for charging posts. The connection on the charging posts should be of type-2 because it’s the most common and standard in Europe. Building a solar plant like this would cost about 12.5 million SEK (excluding cables and labor costs).
