If the battery is accepting certain amount of charging current and there
is enough energy available at +ExtDC input, the charging task enters
Quick Charge mode. In the opposite case, when the charging current
drops below 0.0075 CA even if more energy would be available, the
charging task enters Float Charge mode.
If the battery is discharging (charging current is negative), the
charging task always enters Normal Charge mode.
NOTE
After powering up or reset, it takes several minutes to calculate the
remaining capacity of the battery if the charger remains in Normal
Charge mode.
Quick Charging
The purpose of the Quick Charge mode is to fill the battery as quickly
as possible using a specified quick charge voltage for lead batteries. In
Quick Charge, charging voltage is set to 7.35 V corrected with
temperature coefficient. Charging current is typically the same or one
step higher as in Normal Charge mode.
NOTE
Quick charging is not fully possible for batteries having more than 6
Ah capacity, due to the limited maximum current of the QML102
charger.
When the charging current drops below 0.075 CA, the charger task
enters Normal Charge mode. It also sets the remaining capacity to 90
% if current dropping was caused by battery filling up rather than
missing energy at +ExtDC terminal.
During Quick Charge, the remaining capacity can be reliably
estimated only after a certain amount of time. This is when the
charging voltage has reached the limit and the current has started to
decrease. At this point, the remaining capacity is roughly 60 %.
Normally, this point should be reached within two hours if the battery
was completely empty.
NOTE
If an empty battery (with a voltage less than 5.5 V initially) starts
charging and reaches the 60 % limit very quickly (or does not even
Quick Charge), it is probably damaged and should be replaced to
ensure reliable operation.
