Abstract
A power system includes an engine, a driveshaft, and an energy storage system having a flywheel. The energy storage system further includes a transmission structured to transfer energy between the flywheel and the driveshaft. The transmission includes a differential geartrain and a variator coupled to the differential geartrain and having a variator input shaft and a variator output shaft rotatable at a range of speed ratios. The variator may be coupled to a sun gear in the differential geartrain and controls a pattern of energy transfer between the flywheel and the driveshaft.
