1. A battery system comprising:
a battery management system that monitors a state of a battery; and
a power receiving device that wirelessly receives power from a power transmitting device,
wherein the battery management system calculates an optimum charging condition for the battery based on data on the state of the battery and a power transmission performance of the power transmitting device,
wherein the power receiving device is integrated into the battery management system, and
wherein the battery management system adjusts a duty and a resonance frequency of the power transmitting device when a difference value between the calculated optimum charging condition and a preset reference value is greater than or equal to a threshold value.
