Ampaire has selected Electric Power Systems (EP Systems) under an exclusive agreement to supply the propulsion battery pack for Ampaire’s hybrid-electric upgrade of the Cessna Grand Caravan. The nine-passenger Eco Caravan has undergone ground power tests and will fly in the second half of the year. It is the first hybrid-electric aircraft to enter the certification process with the FAA. A supplemental type certification for the upgraded aircraft is expected in 2024. The EPiCTM energy storage system from EP Systems contains advanced cell technology that offers an energy density of over 200Wh/kg (watt-hours per kilogram) at the battery pack level
