F1 KERS Technology

[Hillhater]

as there have been a few threads running touching on various topics related to KERS ..
Batteries ..http://endless-sphere.com/forums/viewtopic.php?f=14&t=26380
Motors ..http://endless-sphere.com/forums/viewtopic.php?f=30&t=23147
and as there will undoubted be some further interesting developments that may have spin off benefits to us Ebikers ..i thought i would start a common thread to focus the discussion and information gathering
I am expecting some interesting developments now that F1 are using KERS again.
F1Tech has some good discussions on this also that can be useful background, like this translation from an Italian article.

The "Kinetic Battery"
One of the more interesting development to come out of the F1 developments , is the "Hybrid Power Flywheel"
Though not currently being used for F1, it has been applied to Porche's hybrid race car.

Instead of the usual batteries of a hybrid road car, an electrical flywheel power generator fitted in the interior next to the driver stores recaptured energy and delivers it to the electric motors.

the Magnetically Loaded Composite (MLC) flywheel.

The flywheel generator itself is an electric motor with its rotor spinning at speeds of up to 40,000 rpm, storing energy mechanically as rotation energy. The flywheel generator is charged whenever the driver applies the brakes, with the two electric motors reversing their function on the front axle and acting themselves as generators. Then, whenever necessary—i.e., when accelerating out of a bend or when overtaking—the driver is able to call up extra energy from the charged flywheel generator, the flywheel being slowed down electromagnetically in the generator mode and thus supplying up to 120 kW to the two electric motors at the front from its kinetic energy.

One advantage of this "mechanical battery" is that the energy density is much greater than current known "chemical batteries", and that the charge rate is also much greater than chemical processes.

EDIT:

Although he energy storage system was originally developed for use in Formula One by the AT&T Williams team, Williams Hybrid Power is now focused on applications in road vehicles. In October 2009, Williams F1 and the Qatar Science & Technology Park (QSTP) formally signed an agreement to inaugurate the Williams Technology Center (WTC). The WTC is initially tasked with the progression of two Formula One inspired R&D projects with clear commercial goals.

The first is the development of an industrial-application large Magnetically Loaded Composite (MLC) flywheel—essentially a wholly composite flywheel which integrates the magnets of the electric motor into the composite...

Cool this is a good thread we need to studie how the F1 stuff is done to lern what we can do!
