Abstract
Various systems and methods for controlling a maximum current threshold of a battery system within a vehicle are presented. The systems may include a battery module, one or more vehicle systems, a battery management system having a battery monitoring unit that monitors a current parameter, and a battery control system that receives the current parameter from the battery monitoring unit. The battery control system may be configured to identify a current event for the battery module, determine a duration of the current event, compare the duration of the current event to a plurality of time thresholds, determine the current parameter based on the duration of the current event, determine a maximum current parameter based on the duration of the current event and the current parameter, and control the one or more vehicle systems such that a current of the one or more batteries does not exceed the maximum current parameter.
