Claim 6:
7. The battery module of claim 6, wherein after the mode determining step, the battery control circuit conducts a daisy chain upstream step and a daisy chain downstream step;
wherein in the daisy chain upstream step, when the battery module operates in the bottom mode or the middle mode, the upstream output terminal switches to the upstream enabling level;
after the daisy chain upstream step, the battery control circuit conducts the daisy chain downstream step;
wherein in the daisy chain downstream step:
when the battery module operates in the top mode, the downstream output terminal switches to the downstream enabling level; or
when the battery module operates in the middle mode, and the downstream input terminal is at a downstream enabling level, the downstream output terminal switches to the downstream enabling level.
