Abstract: Electric vehicles often face concerns regarding overcharging, leading to detrimental outcomes like pollution, reduced hardware lifespan, and safety hazards. Unlike conventional fuels, electric vehicles lack standardized systems to regulate charging parameters and costs. This absence of fail-safe mechanisms can lead to overcharging, causing negative consequences without intervention. To tackle this issue, the project proposes an Arduino-based solution coupled with a relay sensor and dedicated application. This system aims to prevent overcharging, minimizing both financial and electrical wastage. The project serves as a compact prototype, offering a viable resolution to the problem of unregulated charging in electric vehicles.
