BATTERY CELL SCANNING SYSTEMS AND METHODS
First Claim
1. A method for identifying a fault in a battery cell, the method comprising:
- generating an input signal across a first and a second charge plate, the first charge plate being disposed on a first side of the battery cell and the second charge plate being disposed on a second side of the battery cell;
measuring an open circuit voltage of the battery cell;
comparing the measured open circuit voltage with a reference signal; and
identifying whether the battery cell has a fault based on the comparison.

Abstract
Systems and methods for scanning a battery cell to identify internal faults are disclosed. In certain embodiments, a method for scanning a battery cell for faults may comprise generating an input signal across first and second charge plates disposed on each side of the battery cell. An open circuit voltage of the battery cell generated in response to the input signal may be measured. The measured open circuit voltage may be compared with a reference signal associated with a reference battery cell having no faults. Based on the comparison, a fault and/or a possible fault within the battery cell being scanned may be identified.
