Solar PV Integrated Battery Swappable Charging Station for Electric Vehicles

The battery capacity is one of the major issues to achieve long range and getting acceptance of electric vehicles (EVs) over conventional vehicles. Another major issue is related to required charging time in EVs compared to conventional vehicles. These problems can be solved by implementing fast charging station, which needs high power charging facility. Additionally, battery swapping facility can reduce the charging time further. Hence, the swappable battery station based on fast charging algorithm is desirable for EVs transformation. In this paper, a novel algorithm for fast battery swappable charging station is proposed in order to reduce initial purchase price, minimize charging time and increase driving range. The proposed swappable battery charging station is powered from both the grid and solar PV supplies to supply high power during fast charging. This algorithm allows charging of the swappable as well as fixed batteries within half an hour. The analysis and simulation of the proposed control technique and converter configurations is included. The experiment is performed in the laboratory to validate the proposed fast charging algorithm for both the swappable and fixed batteries in a DC microgrid environment.
