Abstract
Official abstract text for this publication.
Cell group voltages for battery cell groups of a battery module are received from voltage sensors. Cell group currents for the battery cell groups are received from current sensors. Open circuit voltages are generated for each of the battery cell groups based on the cell group voltages and the cell group currents. A normalized open circuit voltage of a first battery cell group of the battery cell groups is generated based on the open circuit voltages of the battery cell groups. A normalized cell group voltage of the first battery cell group is generated based on the cell group voltages of the battery cell groups. An assessment of the normalized open circuit voltage and the normalized cell group voltage of the first battery cell group is performed to determine whether there is an internal soft short in the first battery cell group.
First claim
Opening claim text (preview).
What is claimed is: 1 . A battery internal soft short detection system comprising: at least one processor; and at least one memory communicatively coupled to the at least one processor, the at least one memory comprising instructions that upon execution by the at least one processor, cause the at least one processor to: receive cell group voltages for a plurality of battery cell groups of a battery module from a plurality of voltage sensors; receive cell group currents for…
