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.
Hydraulic hybrids are said to be power dense, while electric hybrids are energy dense.This means that electric hybrids, while able to deliver large amounts of energy over long periods of time are limited by the rate at which the chemical energy in the batteries is converted to mechanical energy and vice versa.
Electric motorcycles can use regenerative braking to both slow the motorcycle down and recharge the batteries at the same. KTM secretly raced a machine with a KERS style regenerative braking system during the 2008 Valenican 125 cc Grand Prix. Although deemed in contravention of the rules, the use of a KERS system preceded its use in Formula 1.
Regenerative braking – The drive motor becomes a generator and recovers energy by converting kinetic to electrical energy, also slowing the vehicle and preventing thermal losses. In addition: May be plugged into the grid to recharge the battery. Supercapacitors assist the battery and recover most energy from braking.
KERS is also possible on a bicycle. The EPA, working with students from the University of Michigan, developed the hydraulic Regenerative Brake Launch Assist (RBLA) [30] This has also been demonstrated by mounting a flywheel on a bike frame and connecting it with a CVT to the back wheel. By shifting the gear, 20% of the kinetic energy can be ...
Most brakes commonly use friction between two surfaces pressed together to convert the kinetic energy of the moving object into heat, though other methods of energy conversion may be employed. For example, regenerative braking converts much of the energy to electrical energy, which may be stored for later use.
allows distributed regenerative braking; the torque is not limited by the wheel with least traction, as it is with a mechanical differential. faster response times; accurate knowledge of traction torque per wheel. However, the ED scheme also come with many disadvantages and drawbacks:
The IMA uses regenerative braking to capture some of the energy that would otherwise be lost as heat during braking and reuse that energy later to help accelerate the vehicle. This has three effects: it increases the rate of acceleration, reduces the work required of the engine, and reduces the frequency of brake hardware replacement. The ...
