Zusammenfassung:	[PROBLEM] To predict the occurrence of short-circuits in a rechargeable battery.[SOLUTION] A rechargeable battery short-circuit prediction device that predicts short-circuits in a rechargeable battery 14 includes one or more processors (CPU 10a) connected to a current sensor that detects a charge current of the rechargeable battery, wherein the one or more processors are programmed to: while the rechargeable battery is being charged, receive a current signal indicating the charge current from the current sensor 12; detect temporal changes in the charge current indicated by the current signal; determine, when the charge current increases over time, that there is a possibility that the rechargeable battery is short-circuiting; and output data indicating a determined result.
