1. An apparatus for updating a current pattern for rapid charging, the apparatus comprising:
a resistance calculation unit configured to calculate an internal resistance of a battery module;
a storage unit configured to store a current pattern for rapid charging of the battery module; and
a calculation unit configured to update the current pattern according to a state of the internal resistance of the battery module,
wherein the calculation unit:
calculates a resistance increase rate based on the internal resistance calculated by the resistance calculation unit,
calculates an adjustment coefficient based on the calculated resistance increase rate, and
updates the current pattern using the calculated adjustment coefficient and the current pattern for charging the battery module.
