First Claim
Patent Images
1. A battery management system comprising:
- a recognition unit configured to determine that a battery is in a non-use state if the battery is not in use for a period of time;
a detection unit configured to detect a battery voltage of the battery while the battery is in the non-use state; and
an indicating unit configured to compare the battery voltage detected by the detection unit with an over-discharge reference voltage and, if the battery voltage is less than the over-discharge reference voltage, to generate a warning signal.

Abstract
A battery management system and a battery pack are disclosed. The battery management system determines that a battery is in a non-use state, and thereafter, detects a battery voltage of the battery. If the battery voltage is less than an over-discharge reference voltage, the system generates a warning signal.
