  • Publication number: 20250079862
    Abstract: Methods and systems are provided for a high-voltage multi-array battery of a plug-in vehicle. In one example, a method may include monitoring a rate of change of a difference in a maximum cell voltage deviation for at least one array of cells of the high-voltage multi-array battery exceeding a predetermined threshold. In response to the rate of change exceeding the predetermined threshold, plug-in charging is aborted and a diagnostic trouble code (DTC) is recorded in a memory of the vehicle.

  • Publication number: 20230341465
    Abstract: A charge time estimating method includes communicating a target state of charge for a traction battery from a first control module to a second control module that is different than the first control module, using the second control module to establish an estimated amount of energy that is needed to charge the traction battery to the target state of charge, communicating the estimated amount of energy from the second control module to the first control module, and using the first control module to establish an estimated time required to charge the traction battery to the target state of charge. The estimated time is at least partially based on the estimated amount of energy.
