Abstract
A battery diagnosis device includes a voltage measurement unit for measuring a voltage of a battery cell, a fitting value calculation unit for calculating a fitting voltage of the battery cell in a rest section after charging and discharging of the battery cell, and a diagnosis unit for diagnosing an abnormality of the battery cell by comparing the measured voltage measured by the voltage measurement unit and the fitting voltage calculated by the fitting value calculation unit, with respect to the rest section of the battery cell.
Claims18
A battery diagnosis device comprising:
- a voltage measurement unit configured to measure a voltage of a battery cell;
- a fitting value calculation unit configured to calculate a fitting voltage of the battery cell in a rest section after charging and discharging of the battery cell;
- and
