Abstract
An ejectable battery system for an aircraft is presented. In one embodiment, the present disclosure provides for a battery pack that can be ejected from the aircraft in the event of a thermal runaway, aircraft malfunction, or impending crash. After ejection the battery can remain attached to the aircraft through a retaining tether. A shock absorber in-line with the tether can decrease tether loads. The present disclosure provides an ejectable battery system capable of detecting a battery pack thermal runaway, aircraft malfunction, or impending crash, opening an aircraft battery hatch, ejecting the battery pack from the aircraft, and retaining the battery pack outside of the aircraft via a tether.
