對于電池溫度沖擊及溫度測試循環(huán)及溫濕度循環(huán)測試要求,各個標準都有明確規(guī)定,例如現(xiàn)行比較權(quán)威的測試標準UN38.3 作了如下規(guī)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℃的條件下,進行高低溫沖擊試驗,在極限溫度中存放時間≥6h,高低溫轉(zhuǎn)換時間≤30min(即降溫速率<=4℃/分鐘),沖擊循環(huán)10次,然后室溫(20±5℃)存放24h,試驗總時間至少一周。符合UN38.3 標準規(guī)定的溫度沖擊試驗機, 對高低溫試驗箱的要**:高低溫轉(zhuǎn)換時間≤30min(即降溫速率<=4℃/分鐘),常用的高低溫箱,降溫時間為1℃/分鐘. 如果您的電池出口需要滿足UN38.3 標準,請留意選型。
