Claim 10:
11. The battery system according to claim 10, wherein
when at least one battery module among the plurality of battery modules includes a battery with a voltage value below a preset first voltage threshold, the module controller is configured or programmed to determine the at least one battery module including the battery with the voltage value below the first voltage threshold to be abnormal; and
when it is determined that a battery module including a battery with a voltage value below a preset second voltage threshold larger than the first voltage threshold is present among the plurality of battery modules, if the current value of the current supplied to the load is less than or equal to the total value of the rated currents of all the battery modules other than the battery module including the battery with the voltage value below the first voltage threshold, the module controller is configured or programmed to perform control to stop the abnormal battery module and not to stop the normal battery modules.
