6.
Enter the “Float current limit” in percentage (with one decimal) of the “Charge current”:
This current is used as current limit in the float stage.
NOTE
Both voltage and current are limits in the Float stage. In the beginning of the stage the
current limit is active until the voltage limit is reached, after which, the voltage limit will be
active.
8.7.3.4 Configuration of Lithium Ion SE type parameters:
Lithium Ion charging process:
•
Bulk stage: Charging starts in Bulk stage with constant current (
Bulk current
). The Bulk stage
continues until the voltage reaches
End voltage
, and the charger goes to absorption stage.
•
Absorption stage: Charging is done with constant voltage (
Absorption voltage
) until the current
drops to
Absorp.end current
, and the charger goes to float stage.
•
Float stage: This is the final stage. Charging is stopped until SE voltage drops to
End
voltage, that
causes restart of charging with constant voltage (
Float voltage
). When the charge current drops to
Absorp.end current
the charging is stopped again. This cycle continues as long as the charger is in
the float stage.
1.
Enter the “Absorption voltage” in percentage (with one decimal) of the “Nominal voltage”:
This value is used as constant voltage value during the Absorption stage.
2.
Enter the “Float voltage” in percentage (with one decimal) of the “Nominal voltage”:
This voltage is used as constant voltage in the Float stage. It is possible to use the same value as
the “Absorption voltage”.
