Modelling of standalone solar photovoltaic based electric bike charging

Abstract Charging the electric vehicles through the use of solar PV systems is a major hurdle in today's era. In the present work, a system is designed for charging Electric bikes at workplaces like schools, colleges, offices, etc. To ensure a reliable charging system, a standalone solar PV system with a battery bank based energy storage unit is employed. It can be seen from the present work that the electric bike at different voltage configurations i.e., 12 V, 24 V, and 36 V, can be charged efficiently. The irradiance level is varied in a way to show a real-life effect that occurs during a summer day. To depict this, irradiance level is assumed to rises from 300 W/m2 to 1000 W/m2 and decline again to 300 W/m2 during the process. The DC bus voltage is successfully maintained constant at a level of 48 V in all three cases. The contribution of the study is the application of a robust solar PV based off-grid design for charging electric bike at the workplaces.
