Presentation

Optimizing aircraft battery performance via thermal management

Electrification of propulsion systems demands batteries with long cycle lives, a high energy density and rapid rechargeability. Battery temperature plays a major role in all three, significantly reducing the battery’s operating performance and capacity, in addition to introducing safety and stability concerns. Therefore, effective thermal management is a key factor in enabling the adoption of all-electric aircraft. The conventional approach to thermal management merely entails the prevention of overheating. However, as will be laid out in this presentation, it can instead be leveraged to optimize the performance, safety and durability of hybrid electric propulsion systems for UAVs and UAM.
