LiFePO4 Charging Mode( Lithium Battery Charge Mode)
4 Stage Charge, Conditioning Process Map
PCM Activation: Once the charger has been properly connected to the battery it will
deliver a constant pulse frequency to activate the PCM before it enters into the
charge program
1. Soft Start Phase
Soft start is applied when the charger has detected a battery at a very Low initial
state of charge. Voltage and current are delivered at a specified rate to help the
battery to recover prior to bulk charge
2. Bulk Charge Phase
With the battery now having been activated and gone through the Soft Start phase
as needed the bulk charge phase gives the battery constant current, taking the
battery up to 80% of its full
3. Absorption Phase
In the absorption phase the battery is given constant voltage while current is reduced
based on actions taken from ongoing battery monitoring until the battery is 100%
charged
4. Full Charge
Charging is complete and the battery can be returned to service or left safely on the
charger indefinitely
