Abstract

The present application relates to a method, device, equipment and medium for determining the quality of a battery pack and a phase change material layer. The battery pack includes a plurality of battery cells, and a safety protection layer is arranged between each battery cell; the safety protection layer includes a phase change material layer and a heat insulation layer; the battery cells store electricity; the safety protection layer absorbs and blocks each battery cell Heat generated by thermal runaway. It can prevent the thermal spread between the battery cells, when one of the battery cells is thermally out of control, the safety protection layer can absorb heat and block the heat, and prevent the thermal spread of the battery pack, so as to reduce the temperature inside the battery pack and prevent The battery pack catches fire, thereby suppressing the thermal runaway of the battery pack.

Description

technical field [0001] The present application relates to the field of battery technology, in particular to a method, device, equipment and medium for determining the quality of a battery pack and a phase change material layer. Background technique [0002] With the development of science and technology, power batteries have become common items in people's daily life and production. The power battery is prone to thermal runaway under certain inducing factors, thus causing safety accidents. [0003] At present, for the thermal runaway of the power battery, the liquid cooling technology is mainly used to suppress the spread of the thermal runaway of the power battery and realize the thermal safety protection between the battery cells in the power battery. [0004] Therefore, the prior art has the problem of limited suppression of the spread of thermal runaway of the power battery and blocking fire of the battery pack. Contents of the invention [0005] Based on this, it is...
