Multi-sensor test system and method for lithium battery thermal runaway detection

Abstract

The invention discloses a multi-sensor test system and method for lithium battery thermal runaway detection. An MCU of a main control module allocates a fixed uniform format identifier to each sensorinterface, and after a main control circuit board is connected with the sensor module, uploaded sensing data contains identifiers of sensor connection interfaces; the sensing data aredistinguished according to the identifier; the type of a data processing algorithm method adopted by the data analysis module is judged according to the type of the sensing data, the sensing data is processed according to the selected data processing algorithm, and the data processing algorithm comprises normalization, filtering and unit unification; and graphical or tabulation processing is carried out on the processed sensing data, and a processing result is outputted and displayed according to an output form preset by a user. The method has good universality, can adapt to tests of various common sensors used for development of lithium battery thermal runaway detection products, and avoids the problems that systems need to be developed independently for different sensor tests and consistency cannot be guaranteed under test conditions.

Description

technical field [0001] The invention belongs to the technical field of lithium batteries, in particular to a multi-sensor testing system and method for thermal runaway detection of lithium batteries. Background technique [0002] In the product development process of the existing lithium battery thermal runaway sensor application, the test of the sensor is indispensable. Especially for new types of sensors, although the manufacturer will provide technical manuals and other materials, and a large amount of information about sensor performance parameters can be obtained through the technical manuals, the information that the manuals can give is very limited. Most of the data in the manuals They are all based on the test results given in the conventional environment, and are not specially developed sensors for the thermal runaway of lithium batteries, so it is usually impossible to directly obtain the detection requirements of the thermal runaway state of lithium batteries. ...
