Abstract [en]

Before vehicles were heavily relied on coal, fossil fuels and wind for power.  Now, they are rapidly being replaced by electric vehicles and or plug-in hybrid electric cars. But these electric cars are still faced with the problem of energy availability because they rely on energy from biomass, hydro power and wind turbines for power generation. The abundance of solar radiation and its use as solar energy as a power source in driving these rapidly increasing electric cars is not only an important decision but also a necessary condition for eradication of environmental pollution.

This study presents a model for charging electric cars from solar energy. Little focus on detailed technologies involved from solar energy capture to battery charging but our main focus is how to provide a modified charging parking lot in Karlskrona city-Sweden. With a surface area of 2850m2, we were able to choose 1STH-350-WH as the right PV modules. Based on the latitude of our design area, a computed 71 degrees angle positioning between solar panel and roof so as to maximise the surface area and optimise the solar irradiance gathering. Based on the power output of approximately116kW these PV modules generated, we further analysed and selected SDP 30KW inverter and Monocrystalline Silicon (1SolTech 1STH-350-WH (350W) solar modules. Also we provide different car charging method by choosing the SAE J1772 standard as one of specifications for dedicated vehicle charging and Clipper Creek HSC-40 as our option of charger. With the data of the generating solar energy every day, charging time, consuming power, we can estimate how many cars the system can handle to charge. Moreover, our system provides AC power from AC power network by general socket type F.

We finally concluded that, our model for charging of electric car batteries was not only supportive but efficient in terms of extracting solar energy from sunlight to charge electric cars, thus making the region an eco-friendly place.
