The Design and Performance Investigation of Solar E-Bike using Flexible Solar Panel by Different Battery Charging Controller

The study was conducted to compare the use of Pulse Width Modulation (PWM) and Maximum Power Point Tracking (MPPT) of the Battery Charging Controller (BCC) from the flexible solar panels to work optimally as a battery charging system on electric bicycles. The independent variables in this experiment are BCC type and solar irradiation. Meanwhile, the dependent variable consists of voltage and current output of the solar panel. The flexible solar panel used is the monocrystalline type andhas a capacity of 100 Wp. In this study, the devices to the optimization of the battery charging system consist of; BCC PWM, BCC MPPT, flexy solar cell, datalogger, and battery. The results showed that PWM Solar charger can be producing the average power output of 29.92 Watt, while the MPPT type is 38.89 Watts. The use of MPPT will increase performance by about 10% compared to PWM. This study concludes that the solar charger controller with MPPT type is successful in optimizing the battery charging system compared to the PWM type.
