Abstract

The invention provides a battery thermal runaway warning method, system and server. The method provided by the present invention comprehensively considers the characteristic variables of the target battery, and can be closer to the actual situation of the target battery itself, thereby making the obtained thermal runaway risk score and thermal runaway risk level more objective, and can accurately execute the corresponding The early warning measures solve the problem that the existing technology cannot effectively monitor the battery thermal runaway risk of electric vehicles.

Description

technical field [0001] The invention relates to the technical field of new energy vehicles, in particular to a battery thermal runaway warning method, system and server. Background technique [0002] At present, with the increasingly serious global environmental protection issues, lithium-ion batteries have been widely used in new energy fields such as electric vehicles and electrochemical energy storage. [0003] However, due to high energy density and unique electrochemical characteristics, lithium-ion batteries have hidden dangers in terms of safety and stability, and battery thermal runaway is the main reason for power battery fires. Once the lithium battery enters a state of thermal runaway due to overcharge, overdischarge, internal short circuit, etc., a large amount of heat will cause the decomposition of the solid electrolyte interface (SEI, solidelectrolyte interphase) film of the negative electrode of the battery, the decomposition of the active material of the pos...
