Revision 1.7.2
Solar Cell
Wind Generator
If the DC Type is set to battery, then the following options may be entered to characterize the battery
and allow the estimation of remaining charge etc.
6.6.3.1 Battery Type
The available battery types are
Flooded/Wet
Gel
AGM
Other
Selecting one of these types causes the remaining parameters to be set to appropriate default values.
6.6.3.2 Nominal Voltage
You may program here the nominal voltage of the battery, which is used only for reporting over the
NMEA 2000 network. Available choices are 6, 12, 24, 32, 36, 42, and 48 Volts.
6.6.3.3 Equalization
You may indicate here whether or not the battery supports equalization. This is used only for
reporting over the NMEA 2000 network. Available choices are
Supported
Not Supported
6.6.3.4 Temperature Coefficient
The capacity of a battery generally increases with increasing temperature. So that the DCM100 can
properly calculate the battery’s state of charge, program this parameter with the increase in battery
capacity, in percent, per increase in temperature, in degrees Celsius. The temperature coefficient can
be set to a value between 0%/°C
– 5%/°C.
6.6.3.5 Peukert Exponent
The Peukert Exponent for the battery can be set to a value between 1.0 and 1.5. Please refer to
Section 4.8 on page 11 for details.
6.6.3.6 Charge Efficiency Factor
The Charge Efficiency Factor for the battery can be set to a value between 5% and 100%. Please
refer to Section 4.6.1 on page 11 for details.
6.6.3.7 Fully Charged Voltage
In order for the DCM100 to determine when a battery is fully charged, it uses three parameters. The
“Fully Charged Voltage” indicates the value voltage at which the battery is considered fully charged if
the battery voltage remains above this value and the battery current remains below the “Fully
Charged Current” for the amount of time defined by the “Fully Charged Time” parameter.
