Abstract

The increasing use of electric bicycles as an environmentally friendly mode of transportation has created a growing need for safe and efficient battery charging systems. One of the main challenges in battery charging systems is the risk of overcharging and overtemperature, which can reduce battery performance and lifespan. This study aims to design and develop a charging protection system for the UNESA Vocational three-wheeled electric bicycle integrated with a solar panel using an ESP32-based Auto Cut-Off method. The developed system utilizes a PZEM-017 voltage sensor, DHT22 and PT100 temperature sensors, and a Solid State Relay (SSR) as an automatic power disconnection actuator. The research employed an experimental method consisting of system design, hardware assembly, functional testing, data collection, and result analysis. Testing was conducted using voltage variations of 54.4 V, 57.6 V, and 60 V for Over Voltage Protection (OVP), and temperature variations of 25°C, 40°C, and 50°C for Over Temperature Protection (OTP). The results indicate that the system successfully detected overcharge and overtemperature conditions and automatically disconnected the charging process according to the predefined set points. The sensor measurement error was found to be less than 1% compared to reference measuring instruments. Furthermore, the hybrid charging system integrating solar panels and grid electricity achieved a remaining battery capacity of 60%, which was higher than the 45% remaining capacity obtained from grid-only charging under the same operating conditions. Therefore, the developed protection system effectively improves battery charging safety while supporting the utilization of renewable energy in three-wheeled electric bicycles.

Abstract

This study is motivated by the increasing demand for sustainable transportation and energy efficiency in three-wheeled electric vehicles. The VU-EV (Vokasi Unesa-Electric Vehicle) was developed with integrated solar panels to improve driving range. The research method used was an experimental approach based on Computational Fluid Dynamics (CFD) simulation using SolidWorks software. This study involved variations in solar panel design and airflow velocities (19, 25, and 35 km/h). The analyzed parameters included drag coefficient (Cd), pressure distribution, and airflow patterns (streamline) to determine the most aerodynamically efficient design. Variations in airflow speed have a significant effect on the flow characteristics and aerodynamic forces of the VU-EV electric bike. At a low speed of 19 km/h the drag force value obtained is 3.251 N and the lift force is 2.43 N. Then at a speed of 25 km/h the drag force value is 5.637 N, while the lift force value is 3.666 N. Then at a speed of 35 km/h the drag force value is 10.970 N, while the lift force value is obtained at 6.557 N. The pressure distribution tends to be even with a small difference, Meanwhile, at higher speeds, there is an increase in pressure at the front due to stagnation points and a decrease in pressure at the rear due to the formation of a clearer wake region, accompanied by an increasingly complex flow pattern with separation and turbulence. As speed increases, drag and lift also increase, suggesting that speed increases not only increase drag but also potentially lower vehicle stability.

Abstract

The increasing use of fossil-fuel-powered vehicles has led to high carbon emissions and air pollution, making it necessary to develop more environmentally friendly and inclusive transportation options. This study aims to design and build a three-wheeled electric bicycle with a solar panel–battery hybrid system as an efficient, stable, and accessible transportation alternative for a wide range of users. The research method employed was Research and Development (R&D), which included the design, assembly, functional testing, and vehicle performance analysis phases. The developed system utilizes a 650 W BLDC motor, a 48 V 20 Ah Sealed Lead Acid (SLA) battery, and a 200 Wp flexible monocrystalline solar panel as an additional energy source. Testing was conducted in three speed modes—Eco, Medium, and Sport—as well as battery charging tests using the solar panel while the vehicle was stationary. The results showed that Eco mode produced the highest average range of 54.4 km, followed by Medium mode at 46.2 km and Sport mode at 38.5 km. Additionally, charging the battery using the solar panel in a horizontal position took an average of 333 minutes. The results of the study show that the solar panel–battery hybrid system is capable of effectively supporting the operation of electric bicycles and providing a more environmentally friendly, energy-efficient, and inclusive transportation alternative.
