  • In a battery-powered electric vehicle, regenerative braking (also called regen) is the conversion of the vehicle's kinetic energy into chemical.

    An easy to understand introduction to how regenerative braking works, including energy-saving systems like flywheels and KERS.

    Tesla is a well-known manufacturer of electric vehicles. The company's founder is not Ilon Mask, as many believe. Mask is one of Tesla's main sponsors and her public face. The company has an interesting principle of work - they do not hide their designs and patents. All of them are available for use and application.

    I was more focused on details then and noticed the drag w/ regenerative braking. It really jerked when I removed my foot from the accelerator.

    No, create an account now. As the car is braking, no energy is dispersed by the flywheel, and the only energy into the flywheel is the initial kinetic energy of the car. I have a slider to control off-throttle coasting regen and another to control braking regen. Archived from the original on 17 May

    How Regenerative Braking Works | HowStuffWorks

    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. In a nutshell, the electric motor is using the vehicle's momentum to recover energy that would be otherwise lost to the brake discs as heat.

    This contrasts with conventional braking systems, where the excess kinetic energy is converted to unwanted and wasted heat by friction in the brakes , or with dynamic brakes , where energy is recovered by using electric motors as generators but is immediately dissipated as heat in resistors. In addition to improving the overall efficiency of the vehicle, regeneration can greatly extend the life of the braking system as its parts do not wear as quickly.

    The most common form of regenerative brake involves an electric motor as an electric generator. In electric railways the electricity generated is fed back into the supply system. In battery electric and hybrid electric vehicles, the energy is stored chemically in a battery , electrically in a bank of capacitors , or mechanically in a rotating flywheel. Hydraulic hybrid vehicles use hydraulic motors to store energy in the form of compressed air. In a fuel cell powered vehicle, the electric energy generated by the motor is used to break waste water down into oxygen, and hydrogen which goes back into the fuel cell for later reuse.

    Regenerative braking is not by itself sufficient as the sole means of safely bringing a vehicle to a standstill, or slowing it as required, so it must be used in conjunction with another braking system such as friction -based braking. Regenerative and friction braking must both be used, creating the need to control them to produce the required total braking. The GM EV-1 was the first commercial car to do this. In and engineers Abraham Farag and Loren Majersik were issued two patents for this brake-by-wire technology.

    Early applications commonly suffered from a serious safety hazard: Electric motors , when used in reverse function as generators , convert mechanical energy into electrical energy. Vehicles propelled by electric motors use them as generators when using regenerative braking, braking by transferring mechanical energy from the wheels to an electrical load.

    Early examples of this system were the front-wheel drive conversions of horse-drawn cabs by Louis Antoine Krieger in Paris in the s. The Krieger electric landaulet had a drive motor in each front wheel with a second set of parallel windings bifilar coil for regenerative braking.

    Raworth's Traction Patents —, offering them economic and operational benefits [5] [6] [7] as explained in some detail by his son Alfred Raworth. These included tramway systems at Devonport , Rawtenstall , Birmingham, Crystal Palace-Croydon , and many others.

    Slowing the speed of the cars or keeping it in control on descending gradients, the motors worked as generators and braked the vehicles. The tram cars also had wheel brakes and track slipper brakes which could stop the tram should the electric braking systems fail. In several cases the tram car motors were shunt wound instead of series wound, and the systems on the Crystal Palace line utilized series-parallel controllers.

    The Baku-Tbilisi-Batumi railway Transcaucasus Railway or Georgian railway started utilizing regenerative braking in the early s. This was especially effective on the steep and dangerous Surami Pass. Electric cars used regenerative braking since the earliest experiments, but this was often a complex affair where the driver had to flip switches between various operational modes in order to use it.
