| 3 |
Standard charging mode Standard charge |
Under the condition of ambient temperature ℃, charge to 79.4V with a constant current of 0.2C and turn to 79.4V constant voltage charging until the charging current ≤ 0.05C. Under the condition of the ambient temperature of 25±2℃,Charge the battery at constant current of 0.2C to reach 79.4V. Then charge the battery at constant 79.4V voltage until the charging current decreasing to 0.05C. |
