1. A method of monitoring a battery assembly, comprising:
- monitoring a parameter associated with the battery assembly to obtain a number of monitored parameter samples;
generating a temporal sequence of monotonically increasing values from the monitored parameter samples; and
analyzing the temporal sequence for an indication of a trend in the monitored parameter toward one of an upper operational boundary or a lower operational boundary to predict a fault condition of the battery assembly.

Abstract
A technique of monitoring a battery assembly may include monitoring a parameter associated with the battery assembly to obtain a number of monitored parameter samples. A temporal sequence of monotonically increasing values may be generated from the monitored parameter samples. The temporal sequence may be analyzed for an indication of a trend in the monitored parameter toward one of an upper operational boundary or a lower operational boundary to predict a fault condition of the battery assembly.
