Abstract [en]

This research is focused to design a type of solar photovoltaic electric vehicle for Shenyang International Horticulture Exposition and a photovoltaic standalone station matched for the same type of six vehicles. Since Shenyang’s latitude is 42°N, the solar vehicle and PV station sometimes have to work in low insolation. Absolutely cost-efficiency is necessary. The m-Si solar cell has similar characteristics to single crystal silicon. It has 11-14% industrial efficiency, good stability and over 20-years lifetime. Additionally it is cheaper and operating better under low insolation than single crystal silicon, and its efficiency is much higher than amorphous silicon solar cell, so it is the best choice used in this project. The gel battery has the electrolyte mixed with H2SO4 solution and Si sol. Its lifetime is two time longer than general AGM lead-acid battery. Other advantages are good against thermal lose control, good overcharge protection, good stability and safety. Although it is more expensive than AGM battery, it’s worth it. Thus, the vehicle installed eight 12V/70Wp m-Si panels and six 8V/150Ah gel batteries. In order to support above type of six solar vehicles operation during continuous five overcast and rainy days in economic way, the PV standalone station need 186 PV panels and 127 gel batteries. The total cost is 582700SEK. The solar charge controller of the vehicle is researched and developed by New Energy Source Research Centre of Shenyang Institute of Engineering, who offers all materials for this project. By the experiments its effectiveness of MPPT and low internal losses is proved. Moreover, The PV vehicle with 560Wp m-Si PV array can run 87km, which is 1.5 times distance more than the general electric car with full load when average radiation is 749W/m2.
