Regenerative braking has a similar energy equation to the equation for the mechanical flywheel. Regenerative braking is a two-step process involving the motor/generator and the battery. The initial kinetic energy is transformed into electrical energy by the generator and is then converted into chemical energy by the battery.
In electrified systems the process of regenerative braking is employed whereby the current produced during braking is fed back into the power supply system for use by other traction units, instead of being wasted as heat. It is normal practice to incorporate both regenerative and rheostatic braking in electrified systems.
The regenerative braking control was designed "to provide the same brake pedal "feel" as a conventional car. [13] This was the first use of regenerative braking technology in the U.S. automobile industry. [14] [15] Altogether, the system provided the car with a range of 150-mile (241 km) when traveling at 50 mph (80 km/h). [16]
In the latter part of the 20th century, vehicles with electrical transmission systems (powered by internal combustion engines, batteries, or fuel cells) began to be developed—one advantage of using electric machines is that specific types can regenerate energy (i.e. act as a regenerative brake)—providing deceleration as well as increasing ...
The HLA system is called a parallel hydraulic hybrid. In parallel systems the original vehicle drive-line remains, allowing the vehicle to operate normally when the HLA system is disengaged. When the HLA is engaged, energy is captured during deceleration and released during acceleration, in contrast to series hydraulic hybrid systems which ...
Recent design innovations have led to the application of electromagnetic brakes to aircraft applications. [1] In this application, a combination motor/generator is used first as a motor to spin the tires up to speed prior to touchdown, thus reducing wear on the tires, and then as a generator to provide regenerative braking.

A Flybrid Systems kinetic energy recovery system. A kinetic energy recovery system ( KERS ) is an automotive system for recovering a moving vehicle 's kinetic energy under braking . The recovered energy is stored in a reservoir (for example a flywheel or high voltage batteries) for later use under acceleration.
Disk electromagnetic brakes are used on vehicles such as trains, and power tools such as circular saws, to stop the blade quickly when the power is turned off.A disk eddy current brake consists of a conductive non-ferromagnetic metal disc attached to the axle of the vehicle's wheel, with an electromagnet located with its poles on each side of the disk, so the magnetic field passes through the ...
