Claim 8:
9. A battery module operating as one of a plurality of battery modules of a battery system, comprising:
an electrochemical cell pack; and
a battery management system configured to
control, based on first instruction information received from a processing module of the battery system, the electrochemical cell pack to perform a discharging or charging operation, wherein the first instruction information is used to instruct to discharge or charge the battery module,
record a target time representing discharge duration, charging duration, or discharge duration and charging duration of the electrochemical cell pack of the battery module, and
determine a state of health of the electrochemical cell pack based on the target time, or send the target time to the processing module of the battery system, so that the processing module determines a state of health of the electrochemical cell pack.
