Abstract

See full text

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.
