FCEVs are fueled with pure hydrogen gas stored in a tank on the vehicle. Similar to conventional internal combustion engine vehicles, they can fuel in less than 4 minutes and have a driving range over 300 miles. FCEVs are equipped with other advanced technologies to increase efficiency, such as regenerative braking systems that capture the energy lost during braking and store it in a battery. Major automobile manufacturers are offering a limited but growing number of production FCEVs to the public in certain markets, in sync with what the developing infrastructure can support.

Abstract presently what the world needs is a method or a technology that saves energy from getting wasted. Energy conservation is the hour of need. In case of automobiles, energy conservation can be done by using regenerative braking systems. When driving an automobile, a great amount of kinetic energy is wasted when brakes are applied, which then makes the start up fairly energy consuming. The main aim of this project was to develop a product that stores the energy which is normally lost during braking, and reuses it. The use of regenerative braking system in automobiles provides us the means to balance the kinetic energy of the vehicle to some extent which is lost during the process of braking.
This technology had mostly replaced the traditional braking system in the vehicles because the traditional braking system always utilizes mechanical friction method to dissipate kinetic energy as heat energy in order to achieve the effect of stopping.
Studies show that in urban driving, about one third to one half of the energy required for operation of a vehicle is consumed during braking. Base on the energy perspective, the kinetic energy is a surplus energy when the electric motor is in the braking state since it dissipated the energy as heat and causes a loss of the overall energy.
This wasted energy actually can be converted to a useful energy especially for the hybrid and electric car. Therefore, regenerative braking had been implemented in the car braking system to recapture this wasted energy. In addition, the total energy saves is dependent on the driving condition, normally it is more effective in city driving rather than highway whereas little braking occurs.
The most common form of regenerative brake involves using an electric motor as an electric generator. The working of the regenerative braking system depends upon the working principle of an electric motor, which is the important component of the system.
Experimental tests show that an electric regenerative braking system seems to offer the most promising technology. The various experimental outputs observed during various test runs are tabulated as below. The parameters compared during the observations include flywheel speed, breaking time and time taken. Power output and time taken for various speeds of flywheel is shown in Table II and the power generation for various braking time is shown in Table III.
The results from some of the test conducted show that around 70% of the energy delivered can be recovered by the system. Problems are expected as any new technology is perfected, but few future technologies have ore potential for improving vehicle efficiency than does regenerative braking.
Regenerative braking is an energy recovery mechanism which slows a vehicle or object by converting its kinetic energy into a form which can be either used immediately or stored until needed. When the driver hits the brakes, energy that is normally lost as heat is instead converted into electricity and stored in a battery.
The regenerative braking system used in the vehicles satisfies the purpose of saving a part of the energy lost during braking. Also it can be operated at high temperature range and are efficient as compared to conventional braking system.
The results from some of the test conducted show that around 30% of the energy delivered can be recovered by the system. The results say that the torque driven by the vehicles is measured. Electrical power generated by motor, generator and battery is very useful and hence it should be used in electric vehicles. The flywheel absorbs energy when braking via a clutch system slowing the car down and speeding up the wheel.

The ultracapacitors have strong absorbing and dispensing capability to enable fast recovery and dispersion of energy in the event of braking and coasting. The engine itself works smoothly as a generator, and the heat-dissipated waste energy in the normal friction-based braking cycle is transformed into electricity by collecting kinetic energy from deacceleration. Due to better energy conservation and its efficiency in commercial vehicles, dynamic energy storage, or flywheel devices are also expected to gain fast momentum. Through implementation, flywheels should experience a boom of a significant weight drop from previous iterations.
