Three Stage Charging Methodology In general, the TITAN T2 will deliver a three stage charge routine to each battery.
1. Stage One will deliver a high rate charge matched to the capabilities of the
battery (typically a one or two hour rate, depending on battery type). During this
stage, six separate cutoff methods are in operation, simultaneously, ensuring the
fastest, safest charge for that battery:
TCO - Temperature cutoff which stops the Stage one charge precisely when
a temperature indicative of full charge is reached;
Dt/dT - A microprocessor based algorithm which measures a rise in
temperature over a specific time, very accurately indicating full charge. This
method is also the recommended method for charging Ni-MH technology;
-ΔV - A method to determine the end of stage one charging by identifying a
characteristic “reverse slope” of a Ni-Cd cell. Since this characteristic can
be disguised by the age, temperature and the number of the cells in a battery,
it can never be employed alone;
CCO - This method requires the identification of the particular battery size
(capacity) and chemistry, an exclusive Anton/Bauer Logic Series feature.
The charger determines the maximum charge time for the particular battery
and uses this information to ensure that overcharge conditions are avoided.
FUL - This determination is made when a fully charged DIGITAL battery is
returned to a charger within specified parameters of time, temperature, and
battery voltage. The DIGITAL battery communicates its fully charged
condition and the charger confirms the parameters and immediately indicates a
fully charged condition, without additional verification.
TEMPERATURE COMPENSATED VCO – For HyTRON series of
batteries. Optimizes VCO cutoff to operate only within certain temperature
parameters.
In addition, a voltage limiting constant current Stage One routine address the critical
parameters of DIONIC batteries.
2. Stage Two charging is a BALANCING or “stabilizing” mode which calculates
each battery pack type to offset any imbalance of the battery’s cells, created by
unequal self discharge or any capacity mismatch of the individual cells in the
pack. This stage can vary in duration from zero to as much as 16 hours,
depending on the condition of the battery. The Stage Two charge for DIONIC
batteries reduces current automatically as the battery charges maintaining the
lithium ion cells at a safe voltage level. A battery will typically leave Stage Two
in 2-4 hours under average operating conditions.
3. Stage Three charging is the Anton/Bauer exclusive Lifesaver maintenance
mode. This patented pulse routine keeps batteries fully charged, free from self-
discharge - indefinitely - without damaging heat associated with a so-called
“trickle charge”. The Stage Three programming for DIONIC monitors the self
discharge of the battery, providing charge only when the battery self discharges
to about 95% of its capacity.
