Power Saving System for Electrical Vehicles

ABSTRACT_Though their mainstream acceptance is hampered by battery life, charging infrastructure, and consumer worries about range anxiety, electric vehicles (EVs) provide a sustainable substitute for fossil-fueled transportation. Current EV systems lack smart power optimisation, which causes ineffective energy use under important low-battery circumstances. Using an ATmega328P microcontroller, this project suggests a Power Saving System that dynamically optimises energy use in EVs. The system adjusts motor performance via an L293D motor driver to enhance driving range and automatically turns off non-essential components—such as lighting, fans, and infotainment systems. It also includes a manual activation function to allow power-saving mode preemptively. This design helps to more efficient EV operation by improving energy use and system dependability, therefore supporting more general adoption of electric mobility solutions.
