Title:
SHORT CIRCUIT DETECTION DEVICE, SHORT CIRCUIT DETECTION METHOD, AND PROGRAM
Document Type and Number:
WIPO Patent Application WO/2024/080167
Kind Code:
A1
Abstract:
This short circuit detection device, for detecting a short circuit occurring in a secondary cell as a detection object, supplies a voltage having a prescribed voltage value after having charged the detection object until a prescribed charging end condition is satisfied, and measures a signal generated in the detection object by supplying of an electric current or voltage. The short circuit detection device stops supplying of the voltage having a prescribed voltage value at least when a short circuit is detected on the basis of the measured signal while the voltage having a prescribed voltage value is being supplied.
