ecolader: rapid discharger/charger series
Operating instructions for software V1.04, date of issue 05 MAY 1998
8.15.6 Aut_DC, Fix_DC
(_ = 1...8 and X)
Purpose
The battery care programs (1DC ... XDC)
balance your batteries in order to erase any
existing memory effect, or to force the
chemistry to "get going". Those batteries in
particular which are only slightly discharged
(e.g. transmitter and receiver batteries),
need to be discharged completely and then
recharged on a regular basis. Irregularly
maintained or brand-new packs often require
this procedure to be repeated several
times in sequence.
Description
The battery connected to the charger is discharged
to the final discharge voltage using
the xxxx-D program, and then recharged
using the xxxx C program (repeated n times
if you are using the xxx_DC program). The
program continues charging until the peak is
detected, then switches to a trickle charge.
The initial value for the discharge current is
calculated from the maximum discharge
power and/or the maximum permissible discharge
current for the ecolader.
When the final discharge voltage is reached
using one of the automatic programs, the
discharge current is reduced until it reaches
a low value.
Continuous charge current adjustment relative
to the pack's energy absorption capacity
in the automatic programs.
The calculated charge current is reduced if
there is a danger that the unit will overheat
or be overloaded.
Select criteria:
If the calculated charge currents turn out too
low in automatic mode due to poor battery
condition, the time limiter eventually trips.
For this reason it may make sense to start
by using a fixed current program (e.g.
Fix2DC) and a current of 0.5 C ... 1 C until
the battery has to some extent "come back
to life".
If the battery refuses to accept currents
above 1 C ... 2 C in automatic mode, it is either
unsuitable for rapid-charging, or it is approaching
the end of its life; it's "had it".

Purpose
This program is ideal for studying the
changing behaviour of individual battery
packs. It provides a useful means of checking
their usefulness based on varying capacity
data.
Description
The battery connected to the charger is
charged up using the xxxx C program, and
then discharged again using the xxxx-D program.
In the automatic programs the ecolader automatically
and regularly calculates the optimum
charge current for the battery.
The calculated charge current is reduced if
there is a danger that the unit will overheat
or be overloaded. The program continues
charging until the peak is detected.
After this, the battery connected to the unit
is discharged to the final discharge voltage.
The initial value for the discharge current is
calculated from the maximum discharge
power and/or the maximum permissible discharge
current for the ecolader.
When the final discharge voltage is reached
using one of the automatic programs, the
discharge current is reduced until it reaches
a low value.
Select criteria:
If the calculated charge currents turn out too
low in automatic mode due to poor battery
condition, the time limiter eventually trips.
For this reason it may make sense to start
by using a fixed current program (e.g.
Fix2DC) and a current of 0.5 C ... 1 C until
the battery has to some extent "come back
to life".
If the battery refuses to accept currents
above 1 C ... 2 C in automatic mode, it is either
unsuitable for rapid-charging, or it is approaching
the end of its life; it's "had it".
Important with all combination programs:
These programs only function if you are
using peak-detect or temperature termination.
Exceeding a charge quantity or
charge time causes the combination program
to be halted.
Setting the number of cycles: see Section 8.19
