1. A battery system comprising:
a battery comprising terminals for electrically coupling to an electrical system;
one or more sensors electrically coupled to the battery and configured to determine sensor data indicative of measured operational parameters of the battery, the measured operational parameters comprising a measured terminal voltage; and
a battery control system communicatively coupled to the one or more sensors, the battery control system being programmed to:
determine a predicted internal resistance of the battery expected to occur during a prediction horizon;
determine a real-time internal resistance of the battery during the prediction horizon;
when the measured terminal voltage of the battery is less than a lower voltage threshold, determine a charging power limit used to control supply of electrical power to the battery based on the predicted internal resistance and control charging of the battery using the charging power limit determined based on the predicted internal resistance; and
when the measured terminal voltage of the battery is greater than the lower voltage threshold, determine the charging power limit based on the real-time internal resistance and control charging of the battery using the charging power limit determined based on the real-time internal resistance.
