SOFTWARE MANUAL C32
22.3 CONFIGURATION BY SYSTEM PARAMETERS
44,1:
= 1 battery type: NiMH charging (default). Other values are not allowed or do not switch on charging.
44,2:
Timer set charging: 1 = 1/10h, i.e. 1: = 6 minutes. On the other hand 250: = 25 hours default is 40: = 4h. Charging
time starts with the charging voltage applied, with received command, e.g. from the TINIT in case of a reset, or
when the voltage value of the battery falls below a limit fixed in
parameter 44,13
.
44,3:
Amount of values used to make the difference of the Delta U voltage. Default is 44,3=60. The outcome of this is a
measurement period of 60 x 2 seconds: = 2 min. The lower the charge current is, the higher this value ought to be.
44,4:
The amount of identifications with Delta U identified as negative, until the end of charge is determined. Default is
44,4=1.
44,5:
Indicates the voltage difference, from where Delta U is identified as valid minus Delta U. 1 LSbit = 0.671 mV.
Default is 44,5=18 x 0.565V = 10mV.
44,6:
Maximum voltage value. 1 LSbit = 39.782 mV. Default is 44,6=169. Thus the maximum voltage value is 169 x
39.782mV = 6.72V. For 4 cells this comes up to a voltage of 1.68V/cell. Charging is ended when this maximum
voltage value is exceeded successively as often as indicated in
parameter 44,7
.
44,7:
Repeat counter for the exceeding of the maximum voltage specified in
parameter 44,6
. The maximum voltage has
to exceed the value indicated in 44,6 44,7 times successively in order to identify the end of charging and to stop
charging. Default is p7=1.
44,8:
P8 matches with
parameter 44,3
for measurement of temperature changes. P8 is the number of values measured
several times within 2 seconds to find out temperature changes. Default is 44,8 = 60. I.e. a Delta T identification
measurement time of 60 x 2 seconds = 2 minutes.
44,9:
corresponds with
parameter 44,4
for the measurement of temperature changes. 44,9 is the number of Delta T
identifications (with
parameter 44,8
=60 within 2 minutes) until Delta T is identified as valid. Default is 44,9=1.
44,10:
matches with
parameter 44,5
for Delta temperature difference. a LSbit is about 0,01°C/32°F. Default is 44,10=64.
That means that the recording interval is identified as a change in temperature at the end of charging, if the
difference in temperature preset in 44,10, which is 0,64°C/33°F (44,10:=64) is succeeded within the amount of
time set in
parameter 44,8
(8:=60, e.g.2 minutes).
44,11:
Maximum temperature value. Matches
parameter 44,6
for temperature. The temperature is measured with an NTC
resistor welded into the battery pack. P11 indicates the maximum temperature value. If this value is exceeded
parameter 44,12
times while charging the batteries, rapid charging is stopped. An estimation formula for a 6.8K
NTC is: p11:=(60°C /140°F - Tmax°C) / 0.6°C. Default setting is 44,11:=25. This is Tmax about 45°C/113°F
Attention: high temperatures result in low and therefore inexact measured values.
44,12:
Corresponds with
parameter 44,7
for temperature. 44,12 is the specification for the repeat counter for the
acceptance of the temperature exceeding criteria. Default is 44,12=1.
44,13:
Determines the voltage level for charging restart with decreasing voltage. In theory 1 LSbit is: 39.782 mV. Default
is p13:=133. This is 133 x 39.782 mV = 5.29V. With 4 cells this means 1.2V/cell.
44,14:
Trickle charge ratio. After the end of rapid charging this value determines the average value of the trickle charge in
case the charger remains switched on. 1 LSbit equals 2 seconds runtime with 512 seconds off time. Default is
44,14:=10. That means that in a period of 512 seconds the charge current with supposed 300 mA is on for 10 x 2
seconds = 20 seconds. 20 seconds means 3.9% of 512 seconds. Thus charging is effected with 3.9%
corresponding to a medium continuous current of abut 12 mA (trickle charge).
44,15:
Indicates the minimum battery voltage below which a charge time limitation (switch off after a preset charge time)
and the Minus Delta U identification are not realized. Default is 44,15=140. With 4 cells this means a value of 140 x
39.782mV = 5.57V.
