METHOD AND DEVICE WITH BATTERY SHORT RESISTANCE ESTIMATION
This abstract first appeared for US patent application 20250004064 titled 'METHOD AND DEVICE WITH BATTERY SHORT RESISTANCE ESTIMATION
Original Abstract Submitted
a processor-implemented method includes monitoring a plurality of direct current (dc) resistance values of a battery for a predefined time period during one of a constant power charging or discharging window of the battery, determining the plurality of dc resistance values of the battery at a plurality of timestamps corresponding to the predefined time period, determining a deviation of the determined plurality of dc resistance values by comparing the determined plurality of dc resistance values with a plurality of predefined dc resistance values associated with a reference battery, detecting a persistent short circuit in the battery in response to the determined deviation of the determined plurality of dc resistance values being greater than a threshold value, and estimating, in response to detecting the persistent short circuit in the battery, a short resistance of the battery based on a value of power supply in the constant power charging or discharging window and a magnitude of the determined deviation of the determined plurality of dc resistance values with respect to the plurality of predefined dc resistance values.
