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.
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 ...
Besides the regenerative braking, the acceleration was found to be particularly smooth. When the decision was taken to proceed with the new system on the O and P stock, the test train was dismantled, and the equipment was fitted to three battery locomotives [ 20 ] built by the Gloucester Railway Carriage and Wagon Company , which were part of a ...
A computer oversees system operation, determining how to mix the power sources. The Prius operations can be divided into six distinct regimes:– Electric vehicle mode—The ICE is off and the battery powers the motor (or charges during regenerative braking
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 ...
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.
Engine braking: The HSD system has a special transmission setting labelled 'B' (for Brake), that takes the place of a conventional automatic transmission's 'L' setting, providing engine braking on hills. This can be manually selected in place of regenerative braking.
During braking the kinetic energy of the vehicle is used to charge the battery through the regenerative braking. In hydraulic hybrid system, the pump/motor extracts the kinetic energy during braking to pump the working fluid from the reservoir to the accumulator. Working fluid is thus pressurized, which leads to energy storage.
