Lithium battery calorific value analyzer - thermal runaway total heat release testerBTC 80A/Product Overview

This instrument is specifically designed to accurately measure the total heat release of lithium-ion battery cells during thermal runaway.

The instrument mainly consists of core components such as oxygen bomb, inner cylinder, outer cylinder, stirrer, temperature sensor, and heating element. During testing, the battery sample is placed in an oxygen bomb filled with an inert atmosphere and heated out of control through a heating element. The released heat is transferred to the inner cylinder water through the oxygen bomb, and the system monitors the water temperature changes in real time. Based on this, the total heat of thermal runaway is accurately calculated, providing a reliable data basis for battery safety performance evaluation.

The instrument is designed based on the ATC 300A automatic oxygen bomb calorimeter and has all its testing functions. Therefore, in addition to specialized testing for battery thermal runaway, this instrument can also independently perform oxygen bomb calorific value analysis for conventional combustibles, achieving dual functions of battery thermal safety testing and conventional calorific value analysis. It is versatile and effectively expands the comprehensive testing capabilities of the laboratory.
