electric and hybrid vehicles in the face of the growing need for green energy is regenerative braking. This project proposes to combine the regenerative braking system (RBS) of an electric vehicle (EV) powered by an induction motor with a battery energy storage system (BESS). When the motor brakes, it converts kinetic energy into electrical energy, functioning as a generator. The DC-link voltage rises as a result, and an inverter that employs an effective switching method returns the energy to the battery. Recovered energy can be utilised to boost vehicle acceleration or to keep the battery charged during highdemand scenarios like uphill trips. A proportional integral (PI) controller is used to modify the brake current in order to ensure consistent torque braking. The performance of the recommended system is evaluated using a number of simulations. According to the results, the RBS significantly increases energy recovery and overall vehicle economy, making it a viable choice for electric vehicle applications.
Electric vehicles (EVs) are gaining a lot of attention right now because they provide a more environmentally friendly option to cars with internal combustion engines. The development of electric and hybrid vehicles is growing in popularity. Consequently, the public's awareness of global warming has grown, and the price of petrol has also increased. As a result of growing air pollution and oil prices, electric EVs have emerged as the main and last form of transportation. The main power source in a battery-operated EV is the battery, which has problems including insufficient cycles for charging and recharging and poor reactivity when it comes to driving range [2–5]. The aforementioned problems can be resolved by electrochemical batteries, flywheels, ultracapacitors, and other energy sources [5-7]. A number of techniques have been put in place to deal with this problem, including regenerative braking. The battery and ultracapacitor translate and store a portion of the vehicle's kinetic energy, which is stored during deceleration [7–10]. On a smooth road, regenerative braking is not always effective. It can be seen in places where vehicles have to apply the brake, such as speed bumps, pits in the road, and slopes. Regenerative braking is only noticeable when the battery is completely charged; otherwise, EVs must have mechanical brakes. Electric vehicles employ mechanical brakes to enhance the roughness of the wheel in order to decelerate. This loses a lot of energy since when the mechanical brake is engaged, the kinetic energy of the EV is transformed back into electric energy. The motors are easy to regulate and can regenerate. Two-wheel EVs usually use mechanical brakes to reduce or halt their speed, which causes all of the kinetic energy that has been stored to be lost [11–15]. It is possible to recover and store the kinetic energy lost during braking as electrical energy in batteries and ultra capacitors. This energy can be stored in the battery if the

1.Introduction Electric and hybrid electric vehicles (HEVs), with their distinctive features including low emissions, great economy, and quiet operation, are attracting more and more attention. In the age of green technology, electric and hybrid electric vehicles (HEVs)can take the place of conventional cars with internal combustion engines (ICEs). Consequently, they are once again contributing to increased vehicle efficiency. However, the exorbitant price of EVs and HEVs has prevented many of them from being used. The objective of this project is to make EV settings less complicated for users. Finding a method to boost the amount of power that can be recovered by braking is one of the main objectives of research. A control strategy for
