Electric unmanned aerial vehicle and an intelligent method of protecting electricity thereof

An electric unmanned aerial vehicle, comprising:

• a position sensor configured to obtain coordinate information of a present position of the electric unmanned aerial vehicle in real-time;
• a memory storing coordinate information of a preset position of the electric unmanned aerial vehicle;
• and
• a controller in communication with the position sensor and the memory, and being configured to:
• calculate a plurality of safety electricity amounts based on the coordinate information of the present position and the coordinate information of the preset position, the plurality of safety electricity amounts corresponding to a plurality of safety protection commands, respectively,
• compare a present remaining electricity amount of a battery of the electric unmanned aerial vehicle with the plurality of safety electricity amounts to select a safety electricity amount that corresponds to the present remaining electricity amount, and
• perform one of the plurality of safety protection commands that corresponds to the selected safety electricity amount.
