“…Although the Li-ion battery system is relatively maintenance-free, there are concerns over battery overheating, combustion, and explosive disassembly in an uncontrolled charging scenario [8]. A battery management system (BMS) can be applied to tackle this issue, as it regulates the battery charging process [67]. Since there are many cells in a battery pack of an E3W, it requires heat management, cell state of charge monitoring, and current leakage detection so that battery safety and a prolonged lifetime can ensure.…”

“…When the charger and controller operate, the equipment generates heat, causing the temperature of the equipment to rise, and the charger and controller lifetime can decrease with increased temperature [69]. E3W chargers include a rectifier/inverter circuit that produces harmonic contamination to the electric grid [67].…”

“…The electricity required for charging E3Ws is mainly drawn from the power grid. As thousands of electric vehicles are being integrated with power systems, there are likely to have a negative impact on the grid [67]. E3Ws are usually connected overnight and require a large amount of electrical power to charge [16].…”

“…The total harmonic distortion of current varies throughout the charging time of the battery. Higher THD results in higher heating and core loss [67]. Due to the low-quality power supply, charging costs also increase.…”

With rapid urbanization and population growth, there has been a significant increase in the demand for public transport. Fossil-fuel-based internal combustion vehicles are increasingly fulfilling the transport demand and are creating negative impact on the environment. Electric three-wheeler (E3W) vehicles have better prospects in public transport in Bangladesh. The demand and usage of E3W vehicles are increasing rapidly because of their pollution-free and passenger-friendly services. However, there are many challenges, including vehicle stability, regulation, energy supply, battery disposal, etc. This paper discusses the prospects and challenges of the E3Ws in Bangladesh in terms of technological and environmental aspects. The paper addresses the issues of E3W, such as existing structural problems, inherent limitations, consequences of uncontrolled battery charging, and improper battery disposal. Potential solutions to tackle these challenges have been suggested for future sustainable transport in Bangladesh. An overview of existing policies regarding E3W in Bangladesh has been presented, and some recommendations have been made to facilitate the integration of E3Ws in the public transport domain. A review of the technologies can provide a base for strategic E3W policy for the next generation of sustainable transport policies and can help policymakers to frame strategies aiming for clean technology and sustainable development of the transportation system in Bangladesh.
