供电池设计人员和用户评测电池,以便在其设计中使用:
是德科技的自放电测量系统能够显著缩短测量电池自放电电流所需的时间。测试表明,对于圆柱形的 18650 或 21700 电池等小型电池,您只需用 30 分钟到 2 个小时便可快速测量稳定的自放电电流,具体时间取决于电池的特征。对于大容量软包电池(例如 10-60 Ah),完成同一任务只需 1-4 个小时。
以往,观测电池 OCV 发生足够大的变化来确定电池质量,通常需要耗费数周或数月的时间,相比之下,现在的测量系统是一个巨大的进步。它可以显著缩短您的测试周期,将产品更快推向市场。
这种自放电测量系统使用恒电位测量法快速测量自放电电流,并为精确进行直流测量提供了所需要的功能特性:
自放电测量系统也可以测量电池温度。这使您可以观察电池电压和自放电电流随温度的变化。由于电池拥有复杂的温度系数,监测电池温度有利于您控制或消除温度变化所造成的电池电压变化。控制电压变化可以消除自放电电流测量中的一个重要误差源。您可以使用 BT2191A 标配的 T 型热电偶,或使用自己的传感器和接线。支持的传感器包括 T、J、K、E、N、R 型热电偶;5kΩ 热敏电阻;Pt100 和 Pt1000 RTD。
