Bluetooth Controlled Hybrid Charging Car

Bluetooth Controlled Hybrid Charging Car

Project Overview

The Bluetooth Controlled Hybrid Charging Car is an innovative smart vehicle project designed to demonstrate modern concepts of wireless control, renewable energy integration, and efficient power management. This system allows a car to be controlled remotely using Bluetooth technology while utilizing a hybrid charging mechanism that can combine battery power with an additional charging source such as solar energy or external DC supply. The project highlights eco-friendly transportation and smart mobility solutions.

Working Principle

The car is controlled through a Bluetooth-enabled mobile application. Commands such as forward, backward, left, right, and stop are sent wirelessly from a smartphone to the car’s microcontroller via a Bluetooth module. The microcontroller processes these commands and controls the motors using a motor driver circuit.

The hybrid charging system ensures continuous operation by charging the onboard battery using multiple energy sources. When one source is unavailable, the system automatically relies on the battery, improving reliability and efficiency.
