Electric aeroplane Elektra One with Kreisel Battery Technology

By 27. November 2014 Allgemein

Elektra One is a single-seater electric aeroplane featuring the very latest aerodynamic design that is easy and safe to fly. This innovative aeroplane was developed by PC-Aero in Nesselwang, Bavaria / Germany. Two ultra-lightweight battery units from Kreisel with a total weight of just 64 kg provide the efficient and reliable energy supply for a range of 400 km with a flight duration of three hours at a speed of 160 kph.

In addition to the advanced glass/carbon-fibre construction, key innovations include exceptional propeller efficiency (90%) as well as a highly efficient electric motor (13.5 kW continuous power). The extremely low noise level (less than 50 dB) at an in-flight propeller speed of 1400 rpm also highlights the very environmentally friendly design of this plane. Operating costs are less than €35/h or €0.2/km. The investment costs for the entire system consisting of electric aeroplane/solar hangar/energy is currently below €100,000. Used with a solar hangar, CO2 emissions amount to almost zero.
