Pressure Vessel for Battery Abuse Test UL 9540A
Product Description
Pressure Vessel for Battery Abuse Test
Pressure Vessel for Battery Abuse Test provides a safe container in which the tested cells can be thermally runaway in a reproducible way while analyzing the conditions of thermal runaway and the changes in temperature and pressure during the thermal runaway process.
The Pressure Vessel consists of an explosion-resistant pressure vessel, a thermal runaway trigger system, a temperature measurement system, and a pressure measurement system, which can trigger thermal runaway of lithium-ion batteries by heating, short-circuiting, overcharging, and over-discharging in the vessel.
At the same time, it can measure the temperature of the surface of the battery thermal runaway cell, the opening temperature of the gas valve, the voltage change and the pressure change inside the chamber, and display the test data and curve. The test device is designed with a gas collection port for sampling the gas generated by the thermal runaway of the battery cell and using gas chromatography for composition anaylsis.
The pressure vessel for battery abuse test is suitable for use in laboratories or research institutes to determine the thermal runaway conditions of lithium-ion batteries, battery safety tests, subsequent extended tests such as composition analysis, lower flammable limit(LFL), upper flammability limit(UFL), explosion pressure test, etc.
Test object: refrigerant or flammable gas
Test indicators: battery temperature, voltage, gas production, gas production rate, thermal runaway starting temperature, etc.
