With 260 Wh/kg cells, the 900 kWh battery capacity (3,460 kg, 7,630 lb) gives the design a range of 540–650 nmi (1,000–1,200 km) at 240 knots and 10,000 ft (3,048 m). This is anticipated to increase as battery technology improves. The batteries have been tested to more than 1,000 cycles, equivalent to 3,000 flight hours, and will then require replacement at a cost of $250,000 - half of the direct operating cost, similar to a piston engine overhaul. Based on U.S. industrial electricity prices, the direct operating cost with nine passengers and two crew, flying at 240 kn (440 km/h), will be $200 per hour, which compares to $600–1,000 per hour for existing aircraft of similar purchase price, for operations on routes under 500 nmi (930 km). This includes piston- and turboprop-powered Cessna 402s, Pilatus PC-12 and Beechcraft King Airs.[5][1] Eviation notes 45% of air routes fall within its 565 nm (1,050 km) range at 260 kt (482 km/h), or 55% of airline flights according to Flightglobal's Cirium data.[6]
The electric drivetrain will have a higher voltage than current electrical systems. The 300-kW and 400-kW chargers will recharge after one hour of flight time in half an hour. Three 260 kW (350 hp) motors drive propellers mounted on the wingtips, located in the vortices to improve efficiency, and mounted on the tail. The unpressurized aircraft will have a flat lower fuselage. The Italian company Magnaghi Aeronautica will supply the landing gear and has already produced the gear for the similarly sized Piaggio P.180 Avanti.[5] It will be built with existing technology, including a composite airframe, distributed propulsion with Siemens electric engines and Honeywell flight control systems, including automatic landing. Mobile charging stations will give one hour of flight per half-hour of charge.[2] At 3,700kg (8,200lb), the battery accounts for 60% of the aircraft take-off weight.[7]
