对于电池温度冲击及温度测试循环及温湿度循环测试要求,各个标准都有明确规定,例如现行比较权威的测试标准UN38.3 作了如下规定:原文如下: 38.3.4.2 TEST T.2 : Thermal testtest procedure: test cells and batteries are to be stored forat least six hours at a test temperature equal to 75 ±2℃, follwedby storage for at least six hours at a test temperature equal to-40±2℃. The max time intervall between test temperature extremes is30 minutes . This procedure is to be repeated 10 times, afterwhich all test cells and batteries are to be stored for 24hours at ambient temperature (20±5℃). For large cells and batteriesthe duration of exposure to the test temperature extremes should beat least 12hours .在75±2℃和-40±2℃的条件下,进行高低温冲击试验,在极限温度中存放时间≥6h,高低温转换时间≤30min(即降温速率<=4℃/分钟),冲击循环10次,然后室温(20±5℃)存放24h,试验总时间至少一周。符合UN38.3 标准规定的温度冲击试验机, 对高低温试验箱的要**:高低温转换时间≤30min(即降温速率<=4℃/分钟),常用的高低温箱,降温时间为1℃/分钟. 如果您的电池出口需要满足UN38.3 标准,请留意选型。
