Title:
WARNING METHOD AND DEVICE FOR THERMAL RUNAWAY OF BATTERY, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2024/060703
Kind Code:
A1
Abstract:
A warning method and device for thermal runaway of a battery, and a storage medium, which relate to the field of thermal runaway of batteries. The change rate of the concentration of a target gas, which is generated by a target battery during a thermal runaway process, is selected as a characteristic parameter. The method comprises: acquiring a concentration value of a target gas around a target battery (S11); determining the change rate of the concentration of the target gas at the current moment according to the concentration value of the target gas (S12); and executing a corresponding warning policy according to a different change rate interval that the change rate of the concentration of the target gas belongs to (S14). Since the target gas generated by the target battery during the thermal runaway process can be obviously presented in an early stage of the thermal runaway of the battery, and can thus be easily detected by a sensor in the early stage of the thermal runaway of the target battery, a set maximum change rate of the concentration of the target gas in different change rate intervals may be relatively small, such that a warning can be given in a more timely manner in the early stage of the thermal runaway of the target battery.
