With the progress of science and technology, technology innovation, the lithium battery also get rapid development, lithium battery began to be applied in all areas of our lives, from a new energy vehicles travel tools electric bicycle to our mobile computers, can be seen lithium battery, but also can appear some safe hidden trouble of lithium-ion batteries, the front of all time Samsung battery bombings, may be use way is wrong, also could be the battery itself lithium battery must pass the overcharge, short circuit, acupuncture, extrusion, heavy impact, such as safety inspection, if no fire, no explosion lithium-ion batteries, then the lithium battery is qualified products, the opposite is not qualified products. The key is how to detect whether lithium battery safety indicators reach regulation?
Through the following three ways to test:
Way: a strong extrusion first tested will be fully charged batteries on the tester of the plane, and then use hydraulic cylinder on 13 + 1 kn extrusion, finally by 32 mm diameter steel bar extrusion battery, if the lithium battery can withstand maximum pressure, and
There was no explosion and fire, explain the lithium battery products are qualified.
Method 2: heavy impact will be after a full battery test, placed in the test of the testing machine in the plane, the diameter of 15.8 mm steel column vertical center in battery, weight 9.1 kg weight from the height of 610 mm free land on the battery at the top of the steel column. The battery can't afford to
Fire, no explosion.
Three ways: the overcharge test the so-called overcharge test, is actually testing the internal of lithium-ion batteries is stable, the method is very simple, first of all, the battery in 1 c on a full charge, and then carried out in accordance with the 3 c overcharge 10 v overcharge test, when the battery charge voltage rises to a certain voltage stability for a period of time, closer to the time when the battery voltage rise quickly, when rose to a certain extent, top hat pulled batteries, voltage dropped to 0 v. Lithium battery in the process without the explosion and fire, lithium battery is qualified products.
