The embodiment of the invention provides a battery bump detection device and method. The temperature in the shell is adjusted to be within a set range through the temperature balance assembly. The controller presets a first air pressure threshold value and a second air pressure threshold value corresponding to each temperature between T0-1 and T0 + 1 through a temperature and air pressure relation algorithm. The air pressure sensor detects the air pressure of the air bag, compares the air pressure with a first air pressure threshold to judge whether the battery swells, and deflates when the air pressure of the air bag reaches a second air pressure threshold. According to the invention, automatic detection and alarm of battery swelling are realized, the swelling battery can be found in time, and safety accidents such as explosion fire caused by battery swelling are avoided. 本申请实施例提供了一种电池鼓包检测装置及其方法，通过温度平衡组件调节壳体内的温度在设定范围内，控制器通过温度气压关系算法预设T0－1至T0+1之间的每个温度对应的第一气压阈值和第二气压阈值，通过气压传感器检测气囊的气压与第一气压阈值比较判断电池是否鼓包，并当气囊的气压达到第二
