The invention discloses a power battery packaging bag with autonomous constant temperature and shockproof functions for an electric vehicle, which is used for isolating temperature exchange between a power battery of the electric vehicle and the outside and maintaining the environment temperature of the power battery within the range of 15-25 DEG C in a temperature slow-release manner so as to reduce the problems of battery endurance attenuation in winter and the like. The power battery cabin is used for accommodating a power battery and a shockproof battery rack and is provided with a temperature sensing device and a temperature conducting air pipe, and the control cabin comprises a temperature management system, a temperature storage barrel filled with temperature bearing liquid and internally provided with a heating device, a condenser, a compressor, various valves and an air pump device. In the temperature range of-40 DEG C to 180 DEG C, the temperature opposite to the ambient temperature is loaded and stored in the temperature bearing liquid, and the temperature is automatically and slowly released to the battery cabin through the temperature conducting air pipe according to the requirement, so that the battery cabin is always kept at the optimal working temperature of 15-25 DEG C. Meanwhile, the packaging bag also has the functions of heating or conveying cold air to passenger cabins and passenger carrying cabins in the vehicle or seats and steering wheels in the vehicle, and has the functions of collision prevention, shock prevention, battery fire suppression by inert gas and the like.

    本发明公开了一种电动汽车用带自主恒温和防震功能的动力电池封装包,用于隔绝电动汽车动力电池与外界的温度交换,并以缓释温度的方式维持动力电池的环境温度在15‑25℃的范围内,以减少冬季电池续航衰减等问题。它包含容纳动力电池、防震电池架、带温度感应装置和导温气管的动力电池舱,和一个包含温度管理系统,装满承温液、内部布设加热装置的储温桶、冷凝器、压缩机,以及各类阀门、气泵装置的控制舱,该仓室能够根据环境温度的不同,在‑40℃至180℃的温度范围区间,于承温液中加载并储存与环境温度相反的温度,并根据需要通过导温气管自动缓释到电池舱,使电池舱始终维持15‑25℃的最佳工作温度。同时,该封装包还兼具向车内乘、载员舱,或者车内座椅、方向盘供暖或输送冷气的功能,以及防撞、防震、惰性气体抑制电池火灾等功能。
