RECHARGEABLE BATTERY SHORT CIRCUIT PREDICTION DEVICE AND RECHARGEABLE BATTERY SHORT CIRCUIT PREDICTION METHOD

摘要

[Problem] To predict the occurrence of a short circuit in a rechargeable battery. [Solution] A rechargeable battery short circuit prediction device is for predicting a short circuit in a rechargeable battery 14, and is characterized by having one or more processors (CPU 10a) connected to a current sensor which detects a charging current for the rechargeable battery, wherein the one or more processors are programmed to, when the rechargeable battery is being charged, receive a current signal indicating a charging current from the current sensor 12, detect a temporal change in the charging current indicated by the current signal, determine, if the charging current increases over time, that the rechargeable battery probably has a short circuit, and output data indicating the result of the determination.
