A battery management system (BMS) is proposed which is used for electronic vehicle that manages a rechargeable battery (cell or battery pack), such as by protecting the battery from operating outside its safe operating area, monitoring its state of charging using Machine Learning algorithm to improve the performance of the designed project. Machine learning and IOT; real-time data from multiple sensors can be analyzed simultaneously, providing a comprehensive view of vehicle health and performance. Machine learning (ML) is the study of algorithms and mathematical models that computer systems use to progressively improve their performance on a specific task. Machine learning algorithms build a mathematical model of sample data, known as “training data”, in order to make predictions or decisions without being explicitly programmed to perform the task.

A Battery Management System (BMS) is proposed for electric vehicles, designed to manage Li-ion battery packs by ensuring safe operation and monitoring their status using an ESP32 microcontroller.

The ESP32 serves as the central controller of the system. Integrated modules include a temperature sensor, Li-ion battery pack with relay, charger, and an OLED display. When any of the Li-ion battery packs are drained, the system automatically activates the charger via the relay, and the voltage levels of each battery pack are displayed on the OLED. The system continuously monitors the temperature, and if it exceeds a predefined threshold, the ESP32 activates a buzzer to issue an alert.

The ESP32 measures voltage from the sensors and, based on the readings, switches the relay to control the charging process. The relay functions as a switch to enable or disable the charging connection as needed, ensuring the safe and efficient operation of the Li-ion battery packs.

The main objectives of the project are:

• Slowing Down the Vehicle: When the driver applies the brakes, instead of using regular brake pads, the motor of the vehicle acts as a generator to slow the vehicle down.
• Turning Kinetic Energy into Electricity: As the motor slows the vehicle, it converts the car’s movement (kinetic energy) into electrical energy.
• Storing Energy: The electrical energy created during braking is sent back to the battery to store it for later use, helping the vehicle go further without using extra energy.
• Smooth Deceleration: Regenerative braking makes the vehicle slow down more smoothly than traditional brakes, but normal brakes are still used if more stopping power is needed.
• Automatic Battery Management: A microcontroller checks the battery’s charge. If the battery is low, it switches on a charger to recharge it and ensures the motor is powered when needed.
• Designing a Simple System: The project focuses on creating a system that efficiently captures energy during braking and manages the battery’s charge automatically for better performance.

With the existing push in the direction of sustainable, clean sources of power, it is no surprise that solar power has become one of the most popular alternative energy sources. Solar power is amazing. On average, every square meter of Earth’s surface receives 164 watts of solar energy. In other words, you could stand a really powerful (150 watt) table lamp on every square meter of Earth’s surface and light up the whole planet with the Sun’s energy! Or, to put it another way, if we covered just one percent of the Sahara Desert with solar panels, we could generate enough electricity to power the whole world. That’s the good thing about solar power: there’s an awful lot of it—much more than we could ever use. Free and available everywhere, the power of the sun can be employed to power everything like cell phones and MP3 player. The sun’s energy is usually harvested through solar panels that are made up of photovoltaic cells. These cells can convert the sun’s power into electricity that can be used for a number of purposes. For private use, a handheld solar hybrid charger can be employed to recharge little device for instance a MP3 player, a cell phone, or a camera.

The main features of this project are:

1. Mobile can be charged even while travelling.
2. Simple Circuitry.
3. Easy to operate.

The major building blocks of this project are:

1. Solar cell/plate.
2. Regulator
3. Mobile battery
