项目摘要
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.
电池用于电动和混合动力汽车已有十多年的历史,全球范围内的使用率正在增加,包括航空航天部门。 锂离子电池是温度敏感型设备,这为在加拿大天气条件下长达一年的运行增加了挑战,特别是对于要求严格的航空航天部门。低温运行会降低电池容量,降低最大可用功率,并导致过早老化。高温运行会产生热失控和永久故障的风险,并缩短电池寿命。需要改进热监测和热管理,以支持运输方式的电气化,特别是在航空航天部门。Calogy、TriStar Multicopters、舍布鲁克大学(2名教授)和高等技术学院(2名教授)之间的合作伙伴关系是支持下一代电池热管理系统开发的理想选择。Calogy拥有独特的热接地层(TGP)技术,可主动控制电池组内的导热性,并基于使用相变材料(液体到气体)的热管与环境进行热传导。ETS的研究人员将在三峡工程上开发印刷热传感器阵列,以加强热监测。最后,舍布鲁克的研究人员将优化电池组,并在大数据集上使用人工智能算法来识别运行中的潜在故障。TriStar使用锂离子电池的寒冷气候小型无人机将作为该技术的完美测试案例,计划进行飞行演示。这种新的电池包装将证明在低温下的性能得到改善,并在飞机寿命期间改善老化特性。
