Pre-charge Stage: When the battery is connected to the charger, the charger shall detect the voltage of the battery. For the battery's voltage at between V1-V2 or the battery pack is pre-charged at a current betweent I0-I1. When the battery's voltage reaches V2 or the charge time reaches S1, the charge enters into next stage. Parameters refer to Table 1, Appendix.
       2. Constant Current Charge Stage: Charge current is I2; When the charge voltage reaches V3 or the charge time reaches S2, the charge enters into next stage. Parameters refer to Table 2, Appendix.
       3. Constant Current Charge Stage: Charge current is I3; When the maximum voltage reaches V4 or the charge time reaches S3, the charge enters into next stage.Parameters refer to Table 3, Appendix.
       4. Constant Voltage Limited Current Charge Stage: The constant charge voltage is V4, limited current is I4.When the charge current drops to the lower limit value of I4 as Table 4 shown, or the charge time reaches S4, the charge enters into next stage. Parameters refer to Table 4, Appendix.
       5. Trickle Charge Stage: When the charge time S2 is less than 3 hours, trickle charge is not activated. Otherwise the limited voltage is V5 the constant current is I5 or the charge time reaches S5,the charge enters into next stage.Parameters refer to Table 5, Appendix.
       6. Float Charge Stage: Constant voltage is V6, limited current is I6.The charger shall be cut off while the charge time is within 4 hours.Parameters refer to Table 6, Appendix.Detailed Charging Parameters please refer to "APPENDIX II: CHARGE PARAMETERS FOR EVF SERIES"* All the data and technical curves are for customer's reference only.
