Correct charging method: (1) Standard charging method: Charging at 0.2c5 constant current to the battery terminal voltage is 4.20V, change to constant pressure charging, to charging current <0.
01c5 is considered to be filled. Standard charging method is often used in the calibration of battery capacity, because it is too slow, rarely used in daily use. (2) Fast charging method: charging at 1C5 constant current to the battery terminal voltage is 4.
20V, change to constant current charging, to charging current <0.01c5. Tips for rapid charging method: 1 The initial charging current cannot be too large, so as not to overheat the battery, there is a leakage, burst phenomenon.
2 When the battery terminal is reached 4.20V, it is not necessary to transfer constant pressure immediately, the voltage is high (error <0.5%), and it is not possible to measure four more than 10,000 meter measuring.
Energy storage lithium-ion battery discharge method: (1) Standard discharge method: discharged from 0.2c5 constant current to battery end voltage is 2.75V.
Because it is difficult to meet this condition in everyday use, it is not significant, this method is tightly used for battery capacity calibration. (2) Fast discharge method: Because the lithium ion battery is small, the high current is discharged, at room temperature, discharge can be discharged for more than 54 minutes (90%); 1.5c5 discharge time is more than 30 minutes; 2C5 The discharge time is more than 23 minutes; and it is time to make a short time greater current discharge.
