Systems and methods for detecting leakage paths in a battery sensing circuit

摘要

System and methods for detecting electrical leakages in a battery sensing are presented. In certain embodiments, the systems and methods allow a vehicle battery sensing circuit and/or other associated system to detect certain electrical leakages and implement one or more actions to protect vehicle systems from damage resulting from such leakages.

1. A method for detecting a leakage path in a battery sensing circuit, the method comprising:
measuring a first change in voltage over time of a first cell in a battery stack; measuring a second change in voltage over time of a second cell in the battery stack; determining that the first change in voltage and the second change in voltage are different; measuring a first voltage of the first cell; measuring a second voltage of the second cell; determining that the first voltage and the second voltage are different by at least a first threshold amount; and implementing a protective action in response to determining that the first voltage and the second voltage are different by at least the first threshold amount.
