A transmission for transmitting torque between an energy storage device (1) and an energy source and/or sink (7), the transmission comprising a plurality of clutches (39, 45; 29, 39) in series, each of said clutches (39, 45; 27, 29) being operable to transmit torque while slipping substantially continuously, the transmission comprising control means arranged to control a first (39, 45) of said plurality of clutches to transmit a predetermined level or range of torque while slipping substantially continuously and to control a second (27, 29) of said plurality of clutches in response to variations in the speed of slip of one of said plurality of clutches (39, 45; 27, 29). |
