Abstract
An apparatus for detecting soft shorts of a battery cell and a method for the same are provided. The apparatus includes a sensor to measure voltages of a plurality of battery cells, and a controller to determine a slope of a voltage of each battery cell, the deviation of the slope of the voltage for each battery cell, and detect a battery cell, which has the soft shorts, of the plurality of battery cells, based on the slope and the deviation.
Claims20
An apparatus for detecting soft shorts of a battery cell, the apparatus comprising:
- a sensor configured for measuring voltages of a plurality of battery cells;
- and
- a controller operatively connected to the sensor and configured to determine a slope of a voltage of each battery cell, a deviation of the slope of the voltage for each battery cell, and detect a battery cell, which has the soft shorts, of the plurality of battery cells, based on the determined slope and the determined deviation.
A method for detecting soft shorts of a battery cell, the method comprising:
- measuring, by a sensor, voltages of a plurality of battery cells;
