Batteries have been used in electric and hybrid electric vehicles for more than a decade, and worldwide utilization is increasing, including the aerospace sector. Lithium-ion batteries are temperature-sensitive devices, which adds a challenge for year-long operation in Canadian weather especially for the aerospace sector with stringent requirements. Low temperature operation reduces the battery capacity, reduces the maximum power available, and induces premature aging. High temperature operation creates a risk of thermal runaway and permanent failure, and reduces battery lifespan. An improvement in both thermal monitoring and thermal management is required in support to the electrification of transportation modes, especially in the aerospace sector. The partnership between Calogy, TriStar Multicopters, the Université de Sherbrooke (2 professors) and the École de technologie supérieure (2 professors) is ideal to support the development of this next generation of battery thermal management system. Calogy owns a unique thermal ground plane (TGP) technology to actively control the thermal conductivity within the battery pack and with the environment based on heat pipes using phase changing materials (liquid to gas). ETS' researchers will develop arrays of printed thermal sensors on the TGP to enhance the thermal monitoring. Finally, Sherbrooke's researchers will optimize the battery pack and use artificial intelligence algorithm on the large data set to identify potential failures in operation. TriStar' small-scale drone for cold climate using lithium-ion battery will serve as a perfect test case for the technology, where in-flight demonstrations are planned. This new battery packaging will demonstrate both an improved performance at cold temperature and improved aging characteristics over the aircraft lifetime.

十多年来，电池已在电动和混合动力汽车中使用，全球利用率正在增加，包括航空航天部门。锂离子电池是对温度敏感的设备，这为加拿大天气中为期一年的运营增加了挑战，尤其是对于航空航天部门的要求很严格。低温操作可降低电池容量，降低可用的最大功率，并导致过早老化。高温操作会产生热失控和永久故障的风险，并降低电池寿命。需要改进热监测和热管理，以支持运输模式的电气化，尤其是在航空航天部门的电气化。 Calogy，Tristar Multicopter，De Sherbrooke大学（2位教授）和ÉcoleDeTechnologySupérieure（2位教授）之间的合作伙伴关系是支持开发下一代电池热管理系统的理想选择。 Calogy拥有独特的热接地平面（TGP）技术，可积极控制电池组内的导热率，并使用相位更换材料（液体到气体）基于加热管道的环境。 ETS的研究人员将在TGP上开发印刷热传感器的阵列，以增强热监测。最后，Sherbrooke的研究人员将优化电池组，并在大型数据集中使用人工智能算法来识别运行中的潜在故障。 Tristar的小规模无人机使用锂离子电池用于寒冷的气候，将作为计划进行飞行演示的技术的理想测试用例。这种新的电池包装将在冷温下表现出改善的性能，而在飞机寿命中的衰老特征改善。
