Abstract
An apparatus and a method for diagnosing a battery cell. The apparatus may include a reference cell module including at least one reference cell composed of a super-capacitor, a measuring device configured to measure a reference impedance of the reference cell and a battery impedance of the battery cell, and a processor configured to compare the battery impedance with the reference impedance to determine whether there is an abnormality in the battery cell.
Claims16
A diagnostic apparatus for inspecting the state of a battery cell, the apparatus comprising:
- a reference cell module including at least one reference cell composed of a super-capacitor;
- and
- a processor configured to compare a measured battery impedance of the battery cell with a reference impedance of the reference cell to determine whether there is an abnormality in the battery cell.
The diagnostic apparatus of claim 16, wherein the impedance measuring device is configured to re-measure the reference impedance when determined to be the abnormality in the measurement environment, wherein the re-measured reference impedance is updated in a memory.
A diagnostic method for diagnosing the state of a battery cell, the method comprising:
- measuring a reference impedance for at least one reference cell including a super-capacitor;
- measuring a battery impedance for a battery cell of a battery cell module including at least one battery cell;
- and
- comparing the battery impedance with the reference impedance to determine whether there is an abnormality in the battery cell.
