Li-ion battery temperature test chamber test process

a. Preliminary preparation

According to the characteristics of lithium-ion battery, the temperature test chamber for Li-ion battery test in LIB ranges from -70 ° C to +170 ° C. The working room is equipped with a high-precision temperature probe, and the temperature range can be customized. Preliminary inspection of the battery, check the appearance, and then measure its open circuit voltage, internal resistance, initial capacity and record.

b. test

Low temperature performance test: Set a low temperature limit of the battery in the battery test chamber, like -20℃, and put the battery for 4-8 hours. Take it out and leave it at 25℃ for 2 hours to return the temperature, measure the capacity, charge and discharge efficiency, and observe whether there is lithium out and gas.

High temperature characteristic test: set the chamber temperature to 55℃ -65 ℃, put it into the battery for 4-6 hours, and then test the temperature and measure the parameters at low temperature. Pay attention to the capacity attenuation and internal resistance increase caused by the evaporation of the electrolyte and the dissolution of the electrode material.

Temperature cycle reliability test: the temperature of the chamber is cyclic according to 0℃ -40 ℃ -20℃ -60 ℃, each stage is maintained for 2-3 hours, the cycle is 5-10 times, the whole process of monitoring the battery, the cycle of checking the battery life and performance fluctuations, and the evaluation of the structure and material resistance to temperature change.

Thermal shock stability test: First place the battery at -40℃ for 2-3 hours, quickly turn to 80℃ for 2 hours, repeat 3-5 times, observe the integrity of the battery pole, diaphragm, and shell under sudden changes, and measure the performance after each impact.

C. Post-test analysis

Download test data from the controller of the temperature test chamber for Li-ion battery test in LIB to analyze the performance of lithium batteries at different temperatures.

LIB's temperature test chamber for Li-ion battery test can meet diverse battery test requirements according to your customized heating rate, temperature range and other performance, and the 3-year long warranty period makes you no worries.
