[0019] A method for testing the performance of a power lithium-ion battery at room temperature. The specific steps of the method for testing the performance of a power lithium-ion battery at room temperature are as follows:
[0020] Step 1: Discharge the power lithium-ion battery to be measured with a 0.05C current at a constant current, and the discharge voltage is cut off to 2.5V, and the battery is discharged and left for 2 hours;
[0021] Step 2: Charge the power lithium-ion battery after standing for 2 hours in the previous step with 1C current constant current charging, and the charging voltage will cut off to 4.2V, record the charging capacity W1 in this section, and stand for 2 hours;
[0022] Step 3: Charge the power lithium-ion battery with 0.33C current and cut off the charging voltage to 4.2V after the previous step of charging and let it stand for 2h, and record the charging capacity W2 in this section, and let it stand for 2h;
[0023] Step 4: Charge the...
