A series of lithium-ion batteries fitted into the wings of the plane are the sole power source for the E-Fans two 30-kilowatt electric motors. A 6 kW electric motor in the main wheel provides extra power during acceleration and taxiing to reduce electrical power consumption on the ground.

But despite its highly energy efficient design, the E-Fan only has a one-hour range, which means it cannot leave the vicinity of an airport. To combat range anxiety, the plane is outfitted with a backup battery for landing purposes and a parachute that can be deployed as high as 2,000 feet.
