Overcharge test requirements
Charge the sample with 2 times the manufacturer's recommended maximum continuous charging current
The sample cells used for testing are charged at a constant current of 10*C5. Each cell or cell is labeled with a thermal coupling and then charged until the battery or cell explodes, leaks, or the temperature of the surface of the casing returns to ambient temperature or A stable state is reached.
The fully charged battery is first charged to the test voltage with a constant current of 3 times and 3 times the recommended charging current of the manufacturer, and then charged with the test voltage at a constant voltage. During the test, the battery temperature was monitored. When one of the following two conditions occurred, the test was terminated: the battery continued to charge for 7 hours and the manufacturer defined the charging time to be the larger value; the battery temperature dropped to 20% below the peak value.
The battery is discharged at a constant current of 0,2 It A to the final discharge voltage specified by the manufacturer. The sample cell is then charged at a constant current of 2,0 It A.
