Manufacturers detect lithium battery pack quality method manufacturers' test contents are important: points test, charging test, discharge test, short circuit test, internal resistance test, voltage test, resistance test, overcurrent protection test, kit test, etc. The tested tests are standard, routine and rapid charge and discharge tests, respectively, of 0.2c, 0.

5c, and 1c, respectively. It is important to activate the lithium battery pack, and determine its capacity and performance. The charge and discharge test charge and discharge test is to determine whether the charging circuit of the lithium battery pack is normal.

Testing the charging voltage and current have certain requirements. Overcurrent protection test When the lithium battery pack is fully charged, the discharge current is adjusted with adjustable resistance, so that the current increases. When the current is greater than a certain voltage value, the discharge circuit current will break into zero.

Recording the current of the electric discharge is the overcurrent protection current. The user detects that the lithium battery pack quality method is measured and discharged. If there is a related tool, the internal resistance and maximum discharge current can be tested, the quality of the lithium battery, the internal resistance is very small, the maximum discharge current is very large.

With a 20A range of multimeters, the two electrodes of the lithium battery should be shorter, and the current should generally be around 10A, even higher, and can remain for a period of time, relatively stable is a good lithium battery pack. Look at the extent of appearance, such as a lithium battery pack, which is generally 2000mAh, is relatively large. Finishing work is relatively full of packaging.
