Abstract - In recent years, electric bikes (e-bikes) have emerged as an eco-friendly and cost-effective alternative to conventional vehicles. A crucial challenge in the development of e-bikes is the management of battery life, as the limited charge capacity of a single battery may cause the vehicle to stop unexpectedly. This paper proposes an automatic battery swapping system for e-bikes, designed to seamlessly switch between two batteries to ensure continuous operation. The system monitors the battery voltage and automatically switches from Battery 1 to Battery 2 when the voltage level of Battery 1 drops below a pre-defined threshold. Additionally, an LCD display provides real-time battery voltage feedback to the rider. This approach not only maximizes battery life but also ensures that the e-bike runs smoothly with minimal rider intervention, as the batteries are only charged when their charge level falls below 20%. The circuit employs an Arduino microcontroller, voltage sensors, a relay, and an LCD display to manage and monitor the batteries.
