Title:
ABNORMAL TEMPERATURE DETECTION SYSTEM FOR BATTERY CELL
Document Type and Number:
WIPO Patent Application WO/2024/058395
Kind Code:
A1
Abstract:
Disclosed is an abnormal temperature detection system in which the amount of temperature information processing for an entire battery cell can be reduced and stability can be improved, the system comprising: a plurality of light guide plates which overlap at least a partial area of one side of a battery cell in one direction, are struck by electromagnetic waves radiated from the battery cell, and change the path of the electromagnetic waves; an image sensor which overlaps at least a partial area of each of the plurality of light guide plates in the one direction, detects the electromagnetic waves reflected from the light guide plates, and outputs temperature spectrum information for the one side of the battery cell on the basis of the detected electromagnetic waves; and a calculation unit which determines that an abnormal temperature has been detected in the battery cell if the temperature of the one side of the battery cell is outside a preset temperature range.
