Regenerative Discharge Function
The F6 smart charger has a regenerative discharge power up to a capacity of 250W x 4 ,
which can
take the battery power of the output ends back to input end's battery in the balance way . There is no
need to connect to or turn on the power during operation,just directlyconnect the battery ,which going
to receive power,
to the charger's input port, and wait forthe system self
-testing to complete, then connect the discharge
battery to the charger's outputport, and set the
task as
"regeneration discharge"on the
charger to discharge, and recycle it; for
lithium battery, it is strongly recommended
to connect to the balance port of
the chargerfor balanced
discharge.

Battery Activation and Repair
After the charging task starts, if it is detected that the cell voltage be lower than the
pre-charging voltage, the cell will be activated and repaired using one tenth of the task
setting current. After the voltage becomes higher than the pre-charging voltage, the voltage
will be adjusted to the set voltage for charging. Such design can protect the over—dis
-
charged battery , activate and repair it.
About Internal Resistance Measurement
T
he F6 Smart Charger has a cell internal resistance measurement function that is only effective when
performing balanced charging tasks on the battery. About two or three minutes after the start of the
charging task, the internal resistance of the cell is measured and calculated. The internal resistance of
the battery varies with different power levels. Generally speaking, the internal resistance measured is
lower when the power is higher.
When the charger measures the internal resistance of the battery, the charging current is instanta
-
neously adjusted. Therefore, it is normal to find that the current is abruptly changed during the
charging process.
Due to the differences in the ways of measuring the internal resistance ,it is not possible to reach the
test accuracy of internal resistance like those attained on professional measuring instruments . There-
fore, the internal resistance value is only suitable for horizontal comparison reference, such as judging
the consistency of cell performance or comparing the performance parameters of different batteries.
The magnitude of the charging current has certain influence on the accuracy of measuring the internal
resistance. A battery with a large capacity and low internal resistance requires a larger charging current
to accurately measure its internal resistance.
