BATTERY PACK
First Claim
1. A battery pack usable as a power source for an electric device, comprising:
- a battery cell group of a plurality of battery cells which are interconnected in series;
discharge control circuitry for performing discharge control for the battery cell group;
a discharge output terminal through which a discharge output of the battery cell group is supplied to the electric device; and
a casing within which the battery cell group, the discharge control circuitry and the discharge output terminal are housed,wherein the battery cell group cooperates with an input/output terminal electrically connected with the battery cell group to constitute a battery module,the battery module is serially connected with another or other battery modules to constitute a battery module group, andthe battery module group is electrically connected with the discharge control circuitry,the battery pack further comprising;
a first detector detecting at least one of a voltage, a temperature and a current, of at least one of the battery cells in the battery cell group; and
a first selector configured to select one of a mode in which output of a voltage through the input/output terminal is enabled, and a mode in which the output of a voltage is disabled,wherein the discharge control circuitry transmits to the first selector a first signal indicating that output of a voltage to the discharge output terminal is disabled, when the discharge control circuitry attempts to disable the output of a voltage to the discharge output terminal, based on a detection result of the first detector, andthe first selector, based on the first signal received from the discharge control circuitry, disables the output of a voltage through the input/output terminal.

Abstract
A battery pack is disclosed, including: a battery cell group of serially interconnected battery cells; discharge control circuitry for the battery cell group; and a discharge output terminal through which a discharge output of the battery cell group is supplied to an externally coupled electric device. The battery cell group cooperates with an input/output terminal electrically connected with the battery cell group to constitute one of battery modules which are serially connected with one another to constitute a battery module group. The battery pack further includes: a first detector detecting at least one of a voltage, a temperature and a current; and a first selector configured to select one of an enabling mode for the input/output terminal and a disabling mode. The discharge control circuitry transmits to the first selector a first signal indicating that output of a voltage to the discharge output terminal is disabled, when the discharge control circuitry attempts to disable the output of a voltage to the discharge output terminal, based on a detection result of the first detector. The first selector, based on the first signal received from the discharge control circuitry, enters the disabling mode.
