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.
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.
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 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.
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.
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 ...
SpeedE, an academic concept car developed for studying drive-by-wire technologies such as brake-by-wire. Brake-by-wire technology in the automotive industry is the ability to control brakes through electronic means, without a mechanical connection that transfers force to the physical braking system from a driver input apparatus such as a pedal or lever.
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 ...
