Abuse testing of batteries for product development purposes or product approval in accordance with UL 9540a.
Our unique pressure vessel offers a cost efficient and quick method to evaluate gases released by batteries. It allows battery cells and battery assemblies to be safely tested to gather information needed to asses thermal propagation and explosion risks.
If requested, our vessel can be utilized to obtain UL 9540a approval for your product. This method was designed by UL to evaluate the fire characteristics of a battery energy storage system that undergoes thermal runaway. More information about this test standard can be found on UL's website.
Gas composition testing
The pressure vessel allows a controlled environment in which batteries can be driven into thermal runaway safely. Feedthroughs connect the vessel to an inert gas flask and a gas sampling station, while pressures and temperatures are recorded inside the vessel.
The sample is placed inside the reactor and then abused, typically through heating, until it goes into thermal runaway. Once this happens, the battery produces both gas and heat. The increase in pressure and temperature gives information on how much gas is released and at what speed. Then, gas samples are extracted from the vessel and analysed by a gas chromatograph to quantify permanent and volatile species such as O2, CO, CO2, H2, CH4, C2H4, C2H6, C3H6, C3H8, C4H10, and C5H12.
Thermal propagation testing
The pressure vessel is also used to study how thermal runaway propagates between battery cells. Typically, one individual cell is abused while temperature and pressure recordings are made to identify when neighbouring cells are affected.
