The KERS system, or Kinetic Energy Recovery System, is a technology used in Formula 1 racing to recover some of the kinetic energy that is normally lost during braking. This recovered energy can then be used to provide a power boost to the car, which can be particularly useful in overtaking or defending a position on the track.
The KERS system works by capturing the energy that is normally lost as heat when a car brakes. This energy is then stored in a small battery or flywheel, and can be released back into the car's powertrain as needed. The driver can activate the KERS boost by pressing a button on the steering wheel, which releases the stored energy and provides a burst of power to the car.
The use of KERS in Formula 1 has been controversial, with some arguing that it gives an unfair advantage to teams that are able to develop and implement the technology effectively. However, others have argued that KERS helps to make the sport more environmentally friendly, as it allows cars to recover some of the energy that would otherwise be lost during racing.
Overall, the KERS system has had a mixed reception in Formula 1. While it has certainly had an impact on the sport and has helped some teams to gain an advantage, it has also been the source of controversy and debate. Regardless of its ultimate impact, however, the KERS system remains an interesting and innovative technology that continues to evolve and be refined in the world of Formula 1 racing.

It is all based around the fact that energy cannot be created or destroyed, but it can be endlessly converted. The mechanical implementation of KERS is known to be more efficient than the electric equivalent due to the fewer conversions of the energy that are taking place. The use of KERS is not compulsory. Whatever the strategies, KERS and wings are certainly going to keep the lads busy, both in the pits and paddock where, by the way, another new regulation prohibits all-nighters as well as in the cockpit. Also, however, there's a new regulation of chassis reinforcement that further complicates the 640-kg minimum and team targets of optimal ballast positioning.
Their second KERS equipped car finished fifth. Lap time benefits range from approximately 0. Why do they weigh F1 drivers after the race? Foley is not willing to say how fast but says it is somewhere between 50,000 and 100,000rpm. Although KERS was still legal in F1 in the 2010 season, all the teams had agreed not to use it. Use of KERS was still optional as in the 2009 season; and at the start of the 2011 season three teams chose not to use it.
McLaren Mercedes have been working on their in-house KERS for almost two years. See "Tech Tidbits" elsewhere in this issue for a review of his fine book. In order to ensure that the motor is always adding torque to the drive train the forward voltage needs to be greater than the generated voltage. This allows it to be magnetised as a permanent magnet. This is not simple and is achieved using by connecting a Continuously Variable Transmission CVT to the drivetrain. Archived from PDF on 25 June 2008. In contrast, ERS in F1 or KERS, in general, is focused towards deploying the stored electric power to the engine's existing output.
Supercapacitors are used by BMW instead of batteries so that the system remains cool. This is characterized as "the weight applied on the front and rear wheels must not be less than 291 kg and 342 kg, respectively, at all times during the qualifying practice session. The first occurred when the Red Bull Racing team tested their KERS battery for the first time in July: it malfunctioned and caused a fire scare that led to the team's factory being evacuated. This system works with a special flywheel housed in a vacuum and is linked to the differential through a CVT transmission. In a race, drivers can use the KERS to improve overtaking or defence. The CVT subsequently handles the ratio of the torque provided by the motor connected to the engine and the torque from the flywheel.
Toyota have been quoted as saying they think KERS is 'primitive' and not relevant to road car Hybrid systems. How do you calculate flywheel energy? How is the stored energy released by the driver? With magnets, this heat build up limits the ability to keep cycling. By also adding mass to the engine itself there is also the possibility of increasing the engines inertia and hence torque, but this can only be achieved providing that the motor can maintain its angular acceleration. The difference, however, is rather than storing the energy in batteries, or ultracapacitors, on this system it is used to spin a flywheel as a means of storage. However, the clever bit is the flywheel, which is a magnetically loaded composite MLC. Image Credit: The MGU-H also solves turbo lag by using a motor to power the compressor and hence doesn't require the turbine to wait for the exhaust gases. Additional radiators are necessary to cool batteries.
Its associated electronics control unit weighed 10. Archived from PDF on June 25, 2008. Simple KERS system: Press and hold KERS button to deploy KERS energy for extra power boost. Still I do not fully understand how it works, perhaps some simple drawings in their website would be helpful for us non â technical folks. When the KERS project began, the first priority was to study all possible energy store solutions. Firstly to promote the development of environmentally friendly and road car-relevant technologies in Formula One racing; and secondly to aid overtaking.
KERS explained: how a mechanical Kinetic Energy Recovery System works · RaceFans
Using the expertise of industry professionals, we look in detail at racecar design and innovation, whilst also keeping you up to date with news and developments from all the major race series across the globe. With the Prius and a growing hybrid market they absolutely could not be seen to be running a dangerous system so the thing has to be perfect. But just like the battery in your phone when you charge the battery it gets hot so many of the KERS cars feature additional ducting to cool the systems. A mechanical kinetic energy recovery system or KERS is smaller and lighter than a petrol-electric hybrid system, and in real-world conditions it hacks back fuel consumption by a similar percentage to a hybrid. By looking at the numbers the FIA cannot say that there trying to create a greener sport, but instead develop road relevant technologies perhaps.
In fact, teams were so convinced of the advantage of KERS that many of the teams competing for the constructors title changed their cars mid-season to stay competitive in the title race. Being the pinnacle of motorsport, F1 cars are no stranger to complicated systems designed to make the cars go faster. Technical Reason: F1 cars with the driver in them have a minimum weight of 764kg 1684lbs. Well much of this has been thought through and the mechincal systems have to pass a very tough crash test, something as yet the electronic systems have not been exposed to. The FIA rules governing KERS are fairly simple but very restrictive. Monitoring is through a KERS control box that oversees the electric motor when it charges and releases energy.
