摘要： Light is transmitted through or from a separator of a battery cell or scattered within a battery cell and received by one or more light detectors. The light that is normally transmitted through the separator is scattered, absorbed, wavelength-shifted or otherwise distorted by an impending fault in the vicinity of or within the separator. The change in light due to the impending fault is measured by a detector and a signal from the detector is processed to identify the impending fault so that a warning can be generated indicative of the impending fault.

摘要翻译： 光通过电池单元的分离器或从电池单元的分离器传播，或者散布在电池单元内并由一个或多个光检测器接收。 通常通过分离器传播的光被分离器附近或内部即将发生的故障散射，吸收，波长偏移或以其它方式扭曲。 由于即将发生的故障引起的光的变化由检测器测量，并且来自检测器的信号被处理以识别即将发生的故障，使得可以产生指示即将发生的故障的警告。
