Abstract
In a method for detecting an internal short of a battery, the method includes: acquiring first charge state information related to a charge state of the battery; detecting a first reference time point when the first charge state information satisfies a reference condition; acquiring second charge state information related to the charge state of the battery; detecting a second reference time point when the second charge state information satisfies a reference condition; and detecting an internal short of the battery based on a difference between a charge amount from the first reference time point to the second reference time point and a discharge amount from the first reference time point to the second reference time point.

A method for detecting an internal short of a battery, the method comprising:
- acquiring first charge state information related to a charge state of the battery;
- detecting a first reference time point when the first charge state information satisfies a reference condition;
- acquiring second charge state information related to the charge state of the battery;
- detecting a second reference time point when the second charge state information satisfies a reference condition;
- and
- detecting an internal short of the battery based on a difference between a charge amount from the first reference time point to the second reference time point and a discharge amount from the first reference time point to the second reference time point.
A battery control apparatus comprising:
- a measurement unit configured to measure a voltage, a current, and a temperature of a battery;
- a detector configured to acquire charge state information related to a charge state of the battery based on at least one of a voltage value, a current value, and a temperature value of the battery measured by the measurement unit and detecting reference time points when the charge state information satisfies a reference condition;
- an accumulator configured to accumulate, when a first reference time point is detected by the detector, a charge current amount and a discharge current amount of the battery until a second reference time point is detected by the detector and calculating a charge amount and a discharge amount of the battery based on the accumulated charge current amount and the discharge current amount;
- and
- an internal short detector configured to detect an internal short of the battery based on a difference between the charge amount from the first reference time point to the second reference time point and the discharge amount from the first reference time point to the second reference time point.
