  • Method and apparatus for detecting battery leakage
    Patent number: 10985553
    Abstract: A method and apparatus for detecting battery leakage. The method includes determining whether an insulation resistance value difference is smaller than a preset reference difference when a representative insulation resistance value is larger than a preset reference resistance value, wherein the insulation resistance value difference is a difference between a previous representative insulation resistance value and the representative insulation resistance value, allocating a first value to a diagnosis flag when the insulation resistance value difference is smaller than the reference difference, allocating a second value to the diagnosis flag when the insulation resistance value difference is equal to or larger than the reference difference, and activating a count indicator when the second value is allocated to the diagnosis flag. The first value indicates that the representative insulation resistance value is valid. The second value indicates that the representative insulation resistance value is invalid.
