Flywheel keeps electric kart coming
A RIO handles the battery management system on this go kart which incorporates a flywheel. The flywheel basically lengthens the amount of time the electric kart can run from its batteries through regenerative braking. It spins at a top speed of 25,000 rpm as it absorbs energy during braking but was limited to less than half that for demos at the show. Students at UC Berkeley devised the flywheel themselves. It has the structure resembling that of an electric motor. Its rotor weighs 8.5 kg and the flywheel puts out 2.5 kW when spinning at 11,000 rpm. Its peak current output is 300 A.
