Take 3C lithium battery as an example:

The performance test of lithium battery is one of the items that must be carried out in the test, including cycle life, rate, high and low temperature discharge, safety test, etc.

1. Cycle life

The number of cycles of a lithium battery reflects how many times the battery can be repeatedly charged and discharged. Depending on the environment in which the 3C lithium battery is used, the cycle life can test the cycle life of the battery at low temperature, normal temperature, and high temperature.

2. Magnification

In the current fast pace of life, the requirements for fast charging of 3C lithium batteries are getting higher and higher. Therefore, it is necessary to test the rate performance of 3C lithium batteries.

3. High and low temperature discharge test

In the high and low temperature test environment, the 3C lithium battery is subjected to a charge-discharge test. After the charge-discharge cycle is over, the curve and data are retained. Compare with the curve and data at room temperature to see if it meets the specifications stated in the specification.

4. Safety test

The safety test of 3C lithium battery includes overcharge, overdischarge, short circuit, drop, heating, vibration, squeeze, acupuncture, etc., allowing foreign objects to actively damage the battery to test the safety of the battery.

The 3C lithium battery test requires a large current. The shrapnel micro-needle module can achieve a maximum overcurrent of 50A. The current transmission is stable in the range of 1-50A, and a good connection is maintained.
