1. A method comprising:
determining a charge capability of one or more power sources configured to supply charging power to multiple battery packs of a powered system;
calculating a predicted charge time required to charge the battery packs to at least one of a target voltage or a target energy level, the predicted charge time being based at least in part on a current state of charge (SOC) of the battery packs, a pack configuration of the battery packs, and the charge capability;
calculating an updated charge time required to charge the battery packs to the at least one of the target voltage or the target energy level, wherein the updated charge time is calculated while the powered system is receiving the charging power from the one or more power sources during a charging operation; and
in response to determining that the updated charge time deviates from the predicted charge time by greater than a tolerance threshold, modifying the charging operation to reduce a deviation between the updated charge time and the predicted charge time.
