Charging System Status by Indicator
The
Indicator Description List
in Table 3 contains displays that are
caused by charging system abnormalities. When the CMN
indicator is flashing with no other indicator active, there is voltage
present at the battery terminals with the current source off and no
battery. Check the current source and ensure that it produces no
more than the equivalent of 350mV/cell when turned off with no
battery. If the VIN divider resistors were not properly selected, an
open circuit voltage that is actually less than the equivalent of
350mV/cell with the charger off and no battery will not divide
down this open circuit voltage properly and produce the CMN
flash indication. Check the VIN divider and ensure that it properly
normalizes the battery voltage to the electrochemical potential of
about 1.2V cell. If the CMN flash indication occurs with the
battery installed, then the constant current source is producing
more than the equivalent of 350mV/cell when off and there is an
open connection between the charger terminals and the battery.
Check wires, connections, battery terminals, and the battery itself
for an open circuit condition.
If the CMN and OTN indicators are active together, this is an
indication that the battery temperature has dropped to below 10
°
C
after a fast charge was initiated with the battery temperature
normal. If this condition is observed and the battery temperature
did not drop after high charge was initiated, check the thermistor
circuit mechanically for poor contact and electrically for excessive
noise.
If the MMN and CMN indicators are alternately flashing, the likely
cause is no battery with the
ICS1702
programmed in the
discharge-to-charge auxiliary mode. If the battery is present, check
wires, connectors, battery terminals, and the battery itself for an
open circuit condition.
If the MMN indicator is flashing with the OTN indicator active,
this is an indication that the battery is cold while in either the
discharge portion of the discharge-to-charge mode or the discharge
only mode. When in the discharge-to-charge mode, if the battery
does not warm-up into the normal temperature range after the
discharge is complete, the
ICS1702
will enter the maintenance
charge stage. When the battery warms-up, the discharge-to-charge
mode will repeat.
