EPS 55

Fully certified electric propulsion and battery management for electric-powered aeroplanes

  • World Alliance Member
  • Featured Solution
  • Labelled Solution
Label Date November 15, 2019
By H55 AG
From Switzerland
Maturity stage TRL 6 / 7 - Prototype demonstration 1:1

EPS55 is designed to maximise and optimise the use of battery technologies for electric powered aeroplanes. EPS55 proprietary systems replace the conventional fuel-powered aircraft engine with a battery-powered system that aims to eliminate carbon emissions while offering a cleaner (zero GHG emissions), quieter (noise levels less than 55dB), and cost-effective alternative to current propulsion systems for small aeroplanes. EPS55 has perfected the management and monitoring of battery systems, controlling the charging and discharging processes to power the engine drivetrain. This is achieved through a double monitoring system (analogue and digital) that monitors over 100 battery nodes individually, with an independent power supply, with minimal exposure to signal interference during operation. EPS55 monitors battery cells independently for overheating, wear and malfunctions, giving immediate warnings once an issue has been identified. All monitoring and display are done using in-house developed and patented software and hardware that minimises the risk of signal interference during operation. EPS55 is firstly intended to power electrical aircraft trainer (or e-trainer), and in a second phase, EPS55 will power incoming electrical vertical take-off and landing (eVTOL).

The Environmental Benefits

  • Reduction of GHG emissions (250 kg CO2eq per hour flying)
  • Reducing aeroplane noise pollution

The Financial Benefits

  • Reduction of the operating costs associating with flying, with electrical energy costing €6.34/hr of flight, compared to today's €160-220
