Hybrid energy storage system with multiple energy and power densities

摘要

A technique for power an apparatus during a mission includes powering the apparatus with a first energy storage device during a first mission segment of the mission. The first energy storage device has a first energy density and a first peak power rating. The apparatus is powered with a second energy storage device, distinct from the first energy storage device, during a second mission segment of the mission. The second energy storage device has a second energy density lower than the first energy density and a second peak power rating that is greater than the first peak power rating.
