Abstract: A battery module for use in a battery system is operable in a bottom mode, a top mode or a middle mode during an enabled state. The battery module includes a battery unit and a battery control circuit. The battery unit which includes at least one battery generates a battery unit voltage between a positive terminal and a negative terminal of the battery unit. The battery control circuit is powered by the battery unit voltage and is configured to control the battery unit. The battery control circuit includes an enable terminal, an upstream input terminal, an upstream output terminal, a downstream input terminal, and a downstream output terminal. When the enable terminal is at an operation enabling level, or when the upstream input terminal is at an upstream enabling level, the battery module enters the enabled state.
