(1)Standard Charge:
Standard charging is to charge the battery with a constant current
of 115.0A to 3.65V under the condition of an ambient temperature of
25ºC±2ºC, and then transfer to constant voltage charging at 3.65V
until the charging current is less than or equal to 11.5A, and rest
for 30min
(2)Standard Discharge:
Standard discharge is to discharge the battery at a constant
current of 230.0A at an ambient temperature of 25°C± 2°C, discharge
until the voltage reaches 2.5V, and rest for 30 minutes.
The capacity calibration is to charge the cell at a constant
current of 173.0A to 3.65V under the condition of an ambient
temperature of 25ºC±2ºC, and then transfer to constant voltage
charging at 3.65V until the charging current is less than or equal
to 8.65A, rest for 30 minutes, and then discharge according to the
3.6 standard discharge. Repeat the standard charging mode and
standard discharging mode 5 times, the average discharge capacity
of the last 3 times is the 1C discharge capacity, the recorded
discharge capacity is the calibrated capacity C0, and the average
discharge energy of the last 3 times is the 1C discharge energy.
Record the discharge energy as the calibration energy E0.
