Temperature Compensation Based on Battery Type
The
C-Series controller
uses the battery type to determine the
temperature compensated voltage settings. The temperature
compensated charging voltage is normally based on a Lead –
Acid types of battery.
If using Alkaline-type batteries, the R46 resistor on the
circuit board inside the controller will have been clipped as
shown in
“Setting Voltage Parameters for Alkaline Batteries”
on page 26
. If the R46 resistor is cut, the temperature
compensation charging voltage will be based on
Alkaline-type batteries.
See the battery type below to determine the temperature
compensation value change per temperature or refer to the
temperature compensation calculations for a Lead-Acid type
battery as show in
Table 2-2
.
•
Lead-Acid Type Batteries:
5 mV per cell per degree Celsius
•
Alkaline -Type Batteries (NiCad or NiFe):
2 mV per cell per degree Celsius
Table 2-2
describes approximately how much the voltage
may vary depending on the temperature of the batteries.
Automatic Battery Temperature Compensation
Temperature compensation can be accomplished
automatically by using a Battery Temperature Sensor (BTS).
The sensor attaches directly to the side of one of the batteries
in the bank and provides precise battery temperature
information.
See
“Installing the Battery Temperature Sensor” on page 51
for detailed instructions on how and where to install the BTS.
If a BTS is installed, the charge controlling process will be
automatically adjusted for the battery temperature. When
using a BTS, set the Bulk and Float voltage for a battery at
normal room temperature for 77 °F (25 °C).
