Mechanical integrity evaluations include a crush test, where samples of batteries are squeezed between two flat surfaces until 13 kN (3000 lb) is reached, at which point the force is released. Battery safety standards IEC 62133 and UL 2054 specify a similar crush test. The criterion for passing.
What is a lithium-ion safety test?
The standards of lithium-ion safety tests are developed for testing lithium-ion batteries at the developmental stage to ensure that it meets the global safety requirements.
Why are lithium batteries subjected to international test standards?
Safety will always be the reason why lithium batteries are subjected to meet the requirements of international test standards. With lithium batteries undergoing international test standards, it ensures both transportation and usage safety for consumers reducing the risk of being exposed to hazard.
The lithium-ion batteries test standard has improved the usage of this type of batteries in different products due to its benefits. Unlike other types of batteries, lithium-ion batteries have boosted the use of batteries in powering electronics devices to another level.
The main abuse tests (e.g., overcharge, forced discharge, thermal heating, vibration) and their protocol are detailed. The safety of lithium-ion batteries (LiBs) is a major challenge in the development of large-scale applications of batteries in electric vehicles and energy storage systems.
Overcharging and thermal abuse testing remains the most documented battery safety tests in the literature and the most observed reasons for battery safety accidents.
How are lithium batteries tested?
The lithium batteries are subjected to a testing machine, which exposes it to different environmental conditions. The reaction of the lithium batteries towards the effects of the environmental condition in the test machine are recorded. The recorded information will be used to ensure that it qualifies for all the lithium battery safety standards.
