What are the lithium battery testing items?
In order to ensure the safety of lithium-ion batteries, domestic and foreign institutions and organizations have formulated the corresponding safety testing standards for various lithium-ion batteries. The general testing standards generally divide the safety testing items into the following four categories:
1. Electrical test: over charge, over discharge, external short circuit, forced discharge, etc.
2. Mechanical testing: extrusion, needling, shock, vibration, drop, etc.
3. Thermal test: high and low temperature cycle, combustion, microwave heating, etc.
4. Environmental simulation: high-altitude and low-pressure simulation, salt spray test, etc.
Extrusion, needling, impact, vibration, drop, combustion, and high-altitude and low-pressure tests all require professional battery testing machines. In order to ensure the safety performance of the battery, unqualified batteries are checked and battery safety accidents are avoided.
All in all,The above is the importance of lithium battery testing, in general, power lithium battery for the product "quality and safety, product consistency, follow-up maintenance costs" have higher requirements, the quality of the product needs to be better guaranteed, so lithium battery testing is particularly important.
