	Electric vehicle control device - Patent 4388573
		The changeover switch is changed over in the regenerative braking state when another power running state in the direction opposite to the current running direction is instructed in a predetermined time after the stop of a power running state where the chopper had a conduction ratio greater than a preset value.
		The output terminal of the regenerative brake removing circuit 70 is connected through the diode 73 to the resistor 74 and the capacitor 75.
		That is, though the regenerative braking can be conducted at the number n.sub.o of turns in some cases, the above braking cannot be conducted till the number n of turns reaches the value n.sub.1 in the case where the motor current i.sub.M is so controlled as to be made equal to the value i.sub.M1.

		A drum brake is a brake in which the friction is caused by a set of shoes or pads that press against the inner surface of a rotating drum.
		Drum brakes with internal shoes have a particular disadvantage; when the drums are heated by hard braking the diameter of the drum increases due to the expansion of the material and the brakes must be further depressed to obtain effective braking action.
		A muzzle brake is a device that is affixed to the muzzle of a firearm, and which redirects propellant gases to either counter the recoil of the gun, or to prevent the muzzle from climbing during rapid fire.

		Brakes of some description are fitted to most wheel ed vehicles, including automobile s of all kinds, train s, motorcycle s, and bicycle s.
		Some also feature air brakes designed to slow them down in flight (notable examples include some WWII -era fighter aircraft which used "dive brakes" to allow the planes to maintain a safe speed in a steep descent).

		During deceleration, the gasoline engine is switched into fuel cut mode, and the IMA Motor/Generator is operated in generation mode.
		Foot on brake pedal - In this mode, a higher amount of regeneration will be allowed, and the vehicle will slow more rapidly.
		During light brake pedal application, only the IMA Motor/Generator is slowing the car.

	Rear Brake Pads -- Recommendations and Resources (Site not responding. Last check: 2007-11-05)
		Regenerative braking is any technology which allows a vehicle to recapture and store part of the kinetic energy that would otherwise be 'lost' to heat when braking.
		Braking is accomplished by electrically switching motors to act as generators that convert motion into electricity instead of electricity into motion.
		Estimates currently see 30% efficiency; however, the actual efficiency depends on numerous factors, such as the state of charge of the battery, how many wheels are equipped to use the regenerative braking system, and whether the topology used is parallel or series in nature.

	Halfbakery: Regenerative Brake Bike
		I propose a regerative brake for a bicycle.
		I built a little golf car with hydraulic regen braking last year as a demonstrator for one of our industrial partners, and it is now exciting interest from teir one automotive suppliers.
		Regenerative braking could be done by driving an air compressor that increases the tire pressure then bleed them off to a turbine (same compressor) to get an assisted start.

	Adjustable Speed Drives & Drive Systems - Line Regeneration Solutions
		When configured as a regenerative brake, a 3% 1321 line reactor will be required to limit current harmonics on the AC line and to provide impedance between the regenerative brake and the attached drives.
		When configured as a regenerative DC bus supply, a 10% line reactor and an EMI filter/3% reactor combination for high frequency noise attenuation will be required.
		Regenerative Bus Supply operation requires a custom Bulletin 1321 10% line reactor, while Regenerative Brake operation requires a standard Bulletin 1321 3% line reactor.

		In this study, a backward-tracking model from the wheels and tires to the power source (battery or fuel cell) is developed to estimate the effect of rotating inertias for each component during propulsion and regenerative braking of a vehicle.
		The total regenerative brake energy capture is significantly higher (> 70 %) for a FWD vehicle on a dynamometer compared to an on-road case.
		The rest of inertial energy is lost by inefficiencies in components, regenerative brake fraction, and friction braking on the un-driven axle.

	Green Car Congress: East Japan Railway to Introduce Diesel-Electric Hybrid Railcar
		The diesel hybrid, complete with lithium-ion battery and regenerative braking, is a precursor to a planned fuel-cell hybrid traction system.
		In calculating the battery requirements, the JR East engineers factored in capacity for storing regenerative braking energy (the average braking energy used for making a single stop is approximately 1 kWh) and the electric energy necessary to run a railcar for 5 km between stations (approximately 3 kWh).
		Braking: The diesel engine stops and the battery is charged by the regenerative brake.

		The 1336 REGEN Line Regeneration Package can be configured to address the needs of two operating modes; the Regenerative DC Bus Supply mode and the Regenerative Brake mode.
		In the Regenerative Brake Mode the 1336 REGEN is used to remove braking energy from the DC bus and return it back to the three-phase AC utility.
		In the Regenerative DC Bus Supply Mode, the 1336 REGEN supplies both motoring and regenerative current to one or more DC input drives.

		The personnel carrier’s braking system consisted of an electrical regenerative brake, a hydraulic service brake, and a spring applied parking/emergency brake.
		The service brake system failed at the time of the accident and the operator was unable to regain control of the machine using the regenerative or the emergency brake.
		The supplemental braking system does not automatically reset upon machine shutdown after the system has been manually released with the handpump.

	Field tests to evaluate hydrostatic regenerative brake system
		The analysis of hydrostatic hybrid technology is on the rise in several cities across the United States, as several of the major fluid power providers team with businesses and major metropolitan areas to curb the reliance of oil-based products in vehicles.
		When braking, the HRB absorbs energy from the driveline, imparts a retarding force on the drivewheels, and uses the absorbed energy to pump hydraulic fluid into an accumulator.
		Compared to hybrid electric powertrains now entering the market, hydraulic hybrids appear to be inherently better suited for the very high power-handling requirements encountered during regenerative braking, and they require fewer efficiency-robbing energy conversion steps.

		There are two rear brakes: on the pedalling side is a drum brake, and on the motor side is a disc brake that is part of the transaxel.
		Another method of braking is to allow the motor to act as a regenerative brake, which charges the batteries at the same time.
		Brakes: An upgrade to disc brakes on all four wheels will enable secure and responsive braking.
