Cell phone lithium battery is a product battery consisting of an electric cell and a battery protection plate. The cell phone lithium battery will be activated before leaving the factory, after a series of processes of filling the battery case with electrolyte - sealing - chemistry - sub-volume, the cell phone lithium battery is completed The activation of the lithium battery is completed after a series of processes. After activation of the cell phone lithium battery also needs to be tested, the test is intended to verify the quality of the battery is qualified, to eradicate the flow of defective batteries from the source.
Cell phone lithium battery test is mainly the use of power supplies, switches, electronic loads, multimeters and other instruments for battery overcurrent, overvoltage test, as well as to check whether the battery protection plate can quickly make a response to protect the battery. In this process, the battery test module - high-current shrapnel micro-needle module, mainly used for conducting current and transmitting signals.
Cell phone lithium battery test is mainly for the function, safety and reliability of performance, because the lithium battery is easy to overcharge, over discharge, short circuit and other reasons caused by heat, expansion and even explosion and other risks, and therefore must be tested to recognize whether it can be applied.
Cell phone lithium battery function test intention: test the battery's own function can be completed, test content: high and low temperature charging and discharging, charge retention capacity, battery multiplier, capacity, life cycle, etc.; cell phone lithium battery safety test intention: test battery abnormalities, battery protection plate can cut off the current circuit in time to avoid the occurrence of risk incidents, test content: battery overcharge, over discharge, not Normal charging, forced discharge, external short circuit, power limit detection, etc.
Cell phone lithium battery reliability test intention: test whether the battery can work normally under different external environments, test content: low pressure, oscillation, impact, extrusion, free fall, impact, temperature change, shell stress, etc.
Cell phone lithium battery test to ensure the stability of the current flow, high current shrapnel micro pin module as a battery test module, has a good current transfer ability, can be in the range of 1-50A current transfer, and overflow stability and smooth, will not occur current decay. In the field of small pitch, can get used to the pitch value between 0.15mm-0.4mm, longevity and stability are excellent, can maintain a good connection, will not card PIN, broken pin.
Cell phone lithium battery test, in addition to the quality of the battery, but also have to consider how to improve the battery yield, reduce production costs to maximize the benefits. Under the high frequency test, the average life span of high-current shrapnel micro-needle module can reach more than 20w times, if the operation, environment and maintenance are very good, the life span can reach 50w times, the shrapnel head has a self-cleaning design, can be used to the maximum limit, can greatly improve the test power of cell phone lithium battery. In addition, the high-current shrapnel micro-needle module has a short delivery time and high yield rate, and can maintain a long time stability in the cell phone lithium battery test, which is a battery test module with absolute advantages and super high adaptability.
