Claim 11:
12. The battery system of claim 9, wherein each battery unit of the battery system includes plural batteries which are connected in series, wherein each battery control circuit monitors a voltage of each battery of the corresponding battery unit, and when at least one battery of the battery unit has a voltage higher than a voltage upper limit or lower than a voltage lower limit, the battery control circuit generates a protection signal;
wherein the battery control circuit transmits the protection signal to a battery module which is in the bottom mode through the downstream input terminal and the downstream output terminal to turn off an electrical connection between the battery system and the exterior of the battery system; or
the battery control circuit transmits the protection signal to a battery module which is in the top mode through the upstream input terminal and the upstream output terminal to turn off an electrical connection between the battery system and an exterior of the battery system.
