Constant Current Charge Using Cell Monitor
This charge mode is designed
for NiCd type batteries, but can
be used for any battery type,
which requires a constant
current charge and has a cell
voltage of 1.20V. The charge
current is maintained at a
constant current until all the
cells have reached the cell
target voltage. The parameters
for the charge are as follows: -
Cell Target Volts :
When all
the cells have reached this
voltage the charge will stop or
switch to
Extra Time
.
Charge Amps :
This is the
constant current amps to
deliver to the battery until the
Cell Target Volts
has been
reached.
Maximum Time:
This is the
maximum time that the main
charge can be applied, if zero is
entered the extra target fail
time will be requested.
Target Fail :
If the
Cell
Target Volts
has not been
reached within this time then
the charge will stop. Set to
zero if not required.
Extra Time :
If set to a value
greater than zero the charge
will continue for this
Extra
Time
time once the
Cell
Target Volts
has been
reached.
Extra Amps :
If the
Extra Time
has been set to a value greater than zero this
