Dr. Panjabrao Deshmukh Polytechnic, Amravati, Maharashtra, India. --------------------------------------------------------------------------***--------------------------------------------------------------------ABSTRACT However from the point of view of saving energy, mechanical This paper presents a wireless regenerative braking system developed for electric two- wheelers. The main goal of the system is to recover the kinetic energy that is usually wasted as heat during braking and store it in the battery for later use. By doing this, the system helps increase the efficiency of the vehicle and supports longer battery life. A breaker circuit is included to automatically disconnect charging when the battery is full, which improves safety and prevents overcharging. The design also integrates “IOT” technology, where an LCD display and a mobile application “Blynk” show realtime data such as battery percentage, charging status, and vehicle speed. The accelerator is used to control the motor speed, while the brake activates regenerative charging to feed energy back to the battery. Studies have shown that regenerative braking can improve energy efficiency 15 to 20% in lightweight vehicles, while also reducing wear on mechanical brakes. With wireless monitoring and smart control, the proposed system offers a safer, more efficient, and sustainable solution for electric mobility.

INTRODUCTION

Regenerative Braking System involves the removal of the kinetic energy of a moving object by converting it into another form of useful energy, such as electric, pneumatic, or stored kinetic energy. The use of regenerative braking can increase the overall efficiency of a motor vehicle by conserving some of its kinetic energy which can then be used to bring the vehicle back up to speed [1].

LITERATURE REVIEW

J. M. K. C. Donev et. al. (2018) explained different braking methods, with focus on regenerative braking as an energysaving approach. They describe how regenerative braking converts the vehicle’s kinetic energy into electrical energy instead of wasting it as heat.The paper highlights its importance for improving efficiency in electric vehicles compared to conventional braking[1]. Soniya K. Malode and R. H. Adware (2016) discussed the working and advantages of regenerative braking systems in electric vehicles. They explain how kinetic energy during braking is converted into electrical energy and stored in the battery. This improves vehicle efficiency and reduces overall energy loss[2].

The regenerative braking has the ability to save the waste energy up to 8-25% [2]. Taking into account the needs of electric scooters to be able to reach their destination before the power stored in the battery is exhausted and the target of implementing electric scooters whose use is on small roads so that braking will often be carried out, this regenerative braking system is considered suitable for application so that it can increase the mileage of electric scooters.[3]

brake increase out much energy while the EV’s kinetic energy is renewed into the thermal one. Now a day’s electric vehicles (EVs) have traditionally much attention for alternate to traditional internal combustion engine (ICE) vehicles. That can be seen due to highly increased awareness of global warming and also rise in cost of petrol prices [2].

Nabila Asyifa Cabriani Lestari et.al investigate a regenerative braking system for electric scooters using a permanent magnet DC motor to recover braking energy. The study shows that the recovered energy improves battery charging efficiency and extends scooter range. This confirms the practicality of regenerative braking in enhancing two-
