1. An emergency high voltage disconnection device for an electric aircraft, the device comprising:
an electrical connection configured to transfer electrical power from a power source of an electric aircraft, wherein the electrical connection comprises:
a first conductor attached to a power source; and
a second conductor attached to the first conductor;
a safety mechanism connected to the first conductor and the second conductor, the safety mechanism having an enabled position and a disabled position, wherein the safety mechanism is configured to:
allow, in the disabled position, the transfer of electrical power from the first conductor to the second conductor;
terminate, in the enabled position, the electrical connection; a sensor configured to detect a sensor datum; and
a controller, the controller configured to initiate a disconnection protocol as a function of a crash element, wherein:
the crash element is determined as a function of sensor datum; and
the disconnection protocol comprises moving the safety mechanism from the disabled position to the enabled position.
