Abstract

The invention relates to a thermal diffusion detection method and system of a battery system, a storage medium and an intelligent terminal, and relates to the technical field of battery safety, and the method comprises the steps: obtaining first temperature information of a first detection point and second temperature information of a second detection point; whether the temperature corresponding to the first temperature information is larger than the preset reference temperature or not is judged; if not, outputting a normal signal; if the temperature is larger than the reference temperature, the difference value is calculated to obtain actual temperature information, the difference value is the difference between the temperature corresponding to the first temperature information and the conversion temperature, and the conversion temperature is the product of the preset conversion rate multiplied by the temperature corresponding to the second temperature information; judging whether a numerical value corresponding to the actual temperature information is greater than the reference temperature; if the temperature is greater than the reference temperature, outputting an abnormal signal; if the temperature is not greater than the reference temperature, outputting a prompt signal. The method and the device have the effect of improving the accuracy of safety analysis of the battery system.

Description

technical field [0001] The present application relates to the field of battery safety technology, in particular to a thermal diffusion detection method, system, storage medium and intelligent terminal of a battery system. Background technique [0002] With the development of battery technology, batteries are often used in the form of battery systems (consisting of multiple single batteries). Due to the increase in the number of batteries, the safety analysis of battery systems is becoming more and more important. [0003] In related technologies, when analyzing the safety of the battery system, since the battery will emit heat when used, the heat level of the battery system is often detected to determine whether the battery system is in a safe state. When the allowable temperature value is exceeded, it indicates that there is an abnormality in the battery system. [0004] With regard to the related technologies mentioned above, the inventor believes that when performing saf...
