Sign upFully certified electric propulsion and battery management for electric-powered aeroplanes
EPS55 brings a fully certified (FOCA, EASA, FAR) Electric Propulsion System (EPS) and battery management system that promotes the optimal use of battery technologies in a safe, clean and cost-effective manner.
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).

Implemented by Harbor Air in North America (United States) in 2021
Solar Impulse spin-off H55 has partnered with Harbor Air, the largest seaplane airline in North America, and magniX, a company specializing in electric motorization, to certify the first regional transport ePlane - the goal is to convert Harbour Air’s entire fleet to electric power. The companies will work with Transport Canada to certify the installation of magniX's electric propulsion unit and the latest generation battery system provided by H55, transforming Harbor Air's seaplanes into a fully electric commercial fleet; an important step forward in commercial-electric aviation.
Result
Roei Ganzarski, CEO of magniX, added: “This partnership is another step forward in our vision of making emission free, all-electric aircraft a reality. With Harbour Air leading the way to become an all-electric airline, [and] H55’s battery technology and magniX’s flight-proven propulsion, we are looking at an electrifying future.”
