Claim 0:
1. A battery system, comprising:
a plurality of battery modules, including a first battery module, wherein each of the battery modules comprises a battery management system and an electrochemical cell pack; and
a processing module configured to control the electrochemical cell pack of each of the battery modules to alternately perform a discharging or charging operation, wherein a sum of power of the electrochemical cell packs in battery modules other than the first battery module is greater than power required by a target power-supplied object,
wherein a battery management system in the first battery module is configured to record a target time representing discharge duration, charging duration, or discharge duration and charging duration of the electrochemical cell pack in the first battery module, and
wherein the processing module or the battery management system in the first battery module is configured to determine a state of health of the electrochemical cell pack in the first battery module based on the target time.
