Analysis of Single Voltage Sampling Break Detection Function of
Lithium Battery Management System

    Abstract: Sample break is a common fault effecting single cells voltage sampling. Therefore, this paper researched the sample break detection function by taking a practical software and hardware platform as an example, and proposed an application strategy to detect the breaks. Furthermore, a judging process of this strategy is presented in order to discover the break as soon as possible. This can prevent mis-operations due to the misjudgement about the fault which is a sample break instead of single inconsistency or over/under-voltage, thereby ensuring the safe and reliable operation of buttery set in real-time.
    Key words: lithium battery management system; single cells voltage sampling; break detection
