<p>A battery management system includes a sensing unit and a main controller unit (MCU) is disclosed. In one aspect, the sensing unit is configured to measure a current value and a voltage value of a battery under a discharge condition of the battery. In addition, the MCU is configured to receive the current and voltage values and further configured to manage capacities of the battery based at least in part on the current and voltage values. In addition, the MCU includes a an unusable capacity calculating unit configured to calculate an unusable capacity corresponding to a portion of a theoretical maximum capacity of the battery that is unusable under the discharge condition, where the unusable capacity is calculated based at least in part on the current value and an internal resistance value of the battery under the discharge condition.</p> |
