Abstract

A system and method for use with a VTOL aircraft with batteries in a state of deep discharge which prepares the aircraft for a safe vertical landing despite the deep discharge initial condition. The method may include preparing the batteries for an intense burst of power as may be needed during the vertical landing. The method may include idling the battery, thermally conditioning the battery, and may further include charging the batteries by regenerative use of the rotors. The preparation of the batteries may then allow for a burst of power used for landing the aircraft.
