What are the purposes of mobile phone lithium-ion battery functional testing?

Mobile phone lithium-ion battery testing is important for performance, safety and reliability, because lithium-ion batteries are prone to heat, expansion or even explosion due to overcharge, overdischarge, short circuit and other reasons, so they must go through Testing can confirm whether it can be applied. Mobile phone lithium-ion battery functional test purpose: to test whether the battery's own function can be realized, test content: high and low temperature charge and discharge, charge retention, battery rate, capacity, life cycle, etc.; mobile phone lithium-ion battery safety test purpose: test When the battery is abnormal, whether the battery protection board can cut off the current circuit in time to prevent dangerous accidents. Test content: overcharge, overdischarge, abnormal charge, forced discharge, external short circuit, power limit test, etc.; mobile phone Lithium-ion battery reliability test purpose: to test whether the battery can work normally in different external environments, test content: low air pressure, vibration, impact, squeeze, free fall, impact, temperature change, shell stress, etc. on the battery. Mobile phone lithium-ion battery detection must ensure the stability of current flow. The high-current shrapnel micro-needle module as a battery detection module has good current transmission capabilities and can transmit current in the range of 1-50A, and overcurrent Stable and smooth, no current attenuation. In the field of small pitch, it can adapt to the pitch value between 0.15mm-0.4mm, has excellent life and stability, can maintain a good connection, and will not jam or break the needle.
