Document Type and Number:
WIPO Patent Application WO/2024/083069
Kind Code:
A1
Abstract:
Provided in the present application are a battery pack, an electric apparatus, a battery pack test method and a computer storage medium. The battery pack comprises: a battery cell module, comprising at least one battery cell; a first acquisition module, comprising at least one first acquisition unit, the first acquisition unit being arranged in the battery cell, and the first acquisition unit being used for acquiring first operating data of the battery cell; a data processing module, connected to the first acquisition unit, and used for carrying out thermal runaway detection on the battery cell according to the first operating data so as to obtain a first detection result; and a second acquisition module, arranged on the exterior of the battery cell module, used for starting when the first detection result indicates a thermal runaway risk being present in any battery cell, and after startup, used for collecting second operating data of the battery cell. The data processing module is further connected to the second acquisition module and further used for carrying out, by means of the second operating data, secondary detection on whether a thermal runaway risk is present in the battery cell, so as to obtain a second detection result.
