That in turn creates windage losses that sap power and produce enormous amounts of heat.

Solution 1 — the flywheel The flywheel is made from carbon filament wrapped round a steel hub and weighs 5kg. Even when restrained, the flywheel will take time to stop rotating and so engineers and anyone else dealing with the car would need to be careful to stay clear of it. The electrical KERS uses an electromagnet to transfer the kinetic energy to electric potential energy that is eventually converted to chemical energy that is stored in a battery. Halfway between the traditional motor and the fully electric Nissan Leaf or the Volkswagen e-Up!

Can flywheel technology drive out the battery from car hybrids?

Engineers at MIT have also implemented an electric bicycle which makes use of KERS which costs less to produce than a typical electric bicycle and hence could lead to lower costs. Toyota has used a supercapacitor for regeneration on Supra HV-R hybrid race car that won the Tokachi Hour endurance race in July Further work has optimised the current design even further. This is an important part of the reliability strategy and units can be assessed in the car with accelerometers attached to look for tell-tale signs of impending failure.


The recovered energy is stored in a reservoir for example a flywheel or high voltage batteries for later use under acceleration. Flybrid has generated a set of generic design tools and been able to consider everything from long, slim cylinders to large, thin pancakes. A False Dawn First published in When Max Mosley announced at the British Grand Prix in that he wanted F1 cars to develop regenerative braking systems he must have hoped he was talking to the right people to achieve his aim.

Kinetic energy recovery system – Wikipedia

When the bus slows down the Flybrid system captures kinetic energy, which is transferred to the flywheel and released when the driver accelerates again. At the following race, Lewis Hamilton became the first driver to take pole position with a KERS car, his teammate, Heikki Kovalainen qualifying second.

When the car brakes, this energy is usually transferred to heat and sound energy that, for the purposes of the car and its driver, is lost. How it works Very simply the system comprises a flywheel connected by a continuously variable transmission [CVT] to the drivetrain.

With the introduction of KERS in the season, flybrld four teams used it at some point in the season: So despite the fact that they can’t store as much energy for the same weight, they might actually be great for city-centre driving, characterised by short distances and endless stop-starts.

The CVT subsequently handles the ratio of the torque provided by the motor connected to the engine and the torque from the flywheel. It then redelivers the stored energy to the drive train by powering a motor. Well, if you’re a bus driver, you already can.

Porsche is currently developing an electrical storage system. Finally, a clutch separates the drive if the revs move beyond the limits of the system. Archived from the original on 6 July To achieve this they upped the speed of the flywheel massively to 64,rpm, which allows a smaller, lighter kerw but also means it has to be contained in a very robust structure in case of failure.

The pair were free from Renault to work from 1 January this year and so on 2 January moved into the Silverstone Technology Centre and began work. Archived from the original on December 28, I already have an account Log in.

This system has many problems including the imbalance caused to the vehicle due to the flywheel.
