Jaunt Air Mobility now plans to address that challenge with a new battery system for its next-generation VTOL drones that promises liquid-cooling performance without the complexity of liquid cooling. Jaunt has selected Calogy Solutions to develop the battery pack for its recently unveiled JC-250 and JX-250 hybrid-electric aircraft. Battery drives performance The battery system forms a core part of Jaunt’s hybrid-electric propulsion architecture. Engineering for advanced air mobility Battery technology has become one of the defining engineering challenges for advanced air mobility. As hybrid-electric aircraft grow larger and more capable, battery cooling is becoming a defining part of aircraft design rather than just another supporting system.
