Abstract
In an apparatus for correcting a voltage of a battery cell and a method thereof. The apparatus includes a voltage sensor configured for measuring voltages of a plurality of battery cells, and a controller which is configured for determining an amount of voltage change of each battery cell corresponding to a preset discharge current, detects target battery cells whose identification numbers have preset intervals while the amount of voltage change does not exceed a threshold value, and corrects the amount of voltage change of each target battery cell.
Claims18
An apparatus for correcting a voltage of a battery cell, the apparatus comprising:
- a voltage sensor configured for measuring voltages of a plurality of battery cells;
- and
- a controller electrically and communicatively connected to the voltage sensor and configured to:
- determine an amount of voltage change of each battery cell corresponding to a preset discharge current;
- detect target battery cells whose identification numbers have preset intervals among the plurality of battery cells while the amount of voltage change does not exceed a threshold value;
- and
- correct the amount of voltage change of each target battery cell.
A method of correcting a voltage of a battery cell, the method comprising:
- measuring, by a voltage sensor, voltages of a plurality of battery cells;
- determining, by a controller electrically and communicatively connected to the voltage sensor, an amount of voltage change of each battery cell corresponding to a preset discharge current;
- detecting, by the controller, target battery cells whose identification numbers have preset intervals among the plurality of battery cells while the amount of voltage change does not exceed a threshold value;
- and
- correcting, by the controller, the amount of voltage change of each target battery cell.
