8.12 Termination criteria
Description:
This function is used to define which criterion
the ecolader is to use to detect the "battery
full" condition
The following criteria are available for you to
select:
Peak:
Termination criterion is the voltage drop in
the charge voltage which occurs with full
cells due to temperature rise.
Peak termination is also sometimes termed
Delta-Peak termination.
Peak and temperature:
Termination criterion is the voltage drop in
the charge voltage combined with cell temperature.
This system only works if the temperature
sensor is connected and a sensible
termination temperature has been set (see
Section 8.8).
That criterion which first registers "battery
full" effects the termination of the charge
current.
Continuous charge (no termination)
For safety reasons the charge current is
pre-set to 300 mA when you select continuous
charging, although it is possible to increase
it to a maximum of 500 mA.
Temperature termination:
This termination criterion is increased cell
temperature.
The function only works correctly if the temperature
sensor is connected, and a sensible
termination temperature has been set;
the optimum temperature varies with the different
methods of charging (see Sections
8.8 and 8.13).
Peak plus delay:
Peak detection is only activated after the
time set in Section 8.9 has elapsed.
Peak plus delay and temperature:
Peak detection is only activated after the
time set in Section 8.9 has elapsed. The
temperature monitoring is active from the
start of the charge process.
Activating the menu point:
Press the akku x button.
Select:
Press the + or - button.
Select range:
As previously described.
Confirm selection:
Press enter
Interrupt:
Press esc
Caution:
Since the ecolader only has one temperature
sensor socket, you should make certain that
you have assigned the sensor to the correct
battery: it makes no sense to activate temperature
termination for Battery 1 and Battery 2 if
both packs are to be charged simultaneously,
as it is not possible to attach one sensor to
both batteries at the same time.
For this reason all other batteries are
switched to peak detect termination if temperature
termination is selected for one pack.
Naturally, you can expect fatal results if the
temperature sensor is connected to Battery 1,
but temperature termination is activated for
Battery 2.
Special feature:
Even when you activate pure temperature
termination, the peak-detect system still
works in the background.
Should you happen to forget to attach the
temperature sensor to the battery, the peak
detect system will activate the buzzer to remind
you of your error.
When you carry out a Power-On-Reset, peak
termination is always (additionally) activated
for reasons of safety (i.e. sensor may not be
attached to battery), and a continuous charge
or a delay period will be switched off.
Display:
A "°" indicates that temperature termination
is activated, and a "^" indicates peak detection.
The criterion which has resulted in switching
off the charge current is displayed on the far
right of the screen after the charge:
PEAK and TEMP refer here to the charge
termination criteria.
If after the charge you see QUANT or TIME,
the charge process was interrupted prematurely
because one of the safety limits was
exceeded.
