Transmission for energy storage device, energy storage device and method for controlling the transmission
A transmission for an energy storage and recovery system comprises a variable slip transmission and a clutch arranged to transmit drive while slipping. The level of torque transmitted through the slipping clutch is dependent on the clutch force but is independent of the clutch slip speed. Preferably the clutch is provided by a plurality of clutches connected in parallel in a range extender. When drive is transferred between clutches in parallel, the clutch forces of both clutches are controlled to maintain the total torque transmitted by the clutches. This reduces torque fluctuations at the energy source/sink during clutch transfer. Where there are two slipping clutches in series, one clutch is controlled to provide the required torque and the other clutch is controlled in response to a clutch slip speed. This helps to control the speed of rotation of the mass between the clutches.

The present invention relates to a flywheel apparatus for energy storage and recovery including a housing within which there is a chamber in which a flywheel on a shaft rotates. The chamber is evacuated to at or near vacuum pressure, so that air resistance-related energy losses of the flywheel as it rotates are reduced. Maintaining near-vacuum pressure within the chamber requires an effective seal between the housing and the shaft. The effective seal must be maintained despite any relative movement (in particular translational movement) of the flywheel and the housing. To this end, the shaft is mounted via a bearing arrangement on a carrier on which is also mounted a sealing arrangement. The carrier is mounted on the housing such that the carrier, the bearing arrangement and the sealing arrangement move substantially together relative to the housing.
