The invention discloses a power battery module of an electric aircraft, which belongs to the technical field of electric devices, and comprises a cooling plate integrated in the module, and compared with a traditional heat conduction path of battery cells, heat conduction glue, a module bottom plate, a heat conduction pad, a battery pack bottom plate and the cooling plate, the heat conduction efficiency is improved; according to the design, heat transfer from the battery cell to the heat-conducting glue to the cooling plate is realized, the heat conduction efficiency is greatly improved, and a higher cooling effect is achieved under the same condition. The original design of the module is that the module is mounted in the wing, so that the weight of a battery pack shell is abandoned, the grouping efficiency of a battery system can be improved by more than 12%, and the airplane has higher load and farther voyage. An exhaust pipeline is included, heat is directly discharged out of the wing during thermal runaway and cannot be conducted to other modules, and the safety of the battery system is improved; meanwhile, the module is far away from passengers, and thermal runaway cannot cause harm to a passenger compartment.
本发明公开了电动飞行器的动力电池模组,属于电力器件技术领域,其包括本方案模组内部集成了冷却板,相比传统电芯→导热胶→模组底板→导热垫→电池包底板→冷却板的热量传导路径,该设计实现电芯→导热胶→冷却板的热量传递,极大提高了热量传导效率,相同条件下达到更高的冷却效果。本模组的设计初衷在于安装在机翼内,进而摒弃了电池包壳体的重量,可将电池系统成组效率提高12%以上,飞机拥有更高的载荷与更远的航程。包含排气管路,热失控时热量直接排出至机翼外,不会传导至其他模组,提高了电池系统安全性;同时模组远离乘客,热失控不会对乘员舱造成危害。
