•
set maximum battery current to 0.1 x battery capacity.
•
set maximum battery current to 0.2 x battery capacity.
6.1.3.2.5 Minimum dc voltage at current limit
Use this function to set a minimum value for the battery-charging voltage when current limiting is
in effect. The permitted range is from 340 to 405 Vdc.
The factory setting of 340 Vdc is recommended for most situations.
6.1.3.3 Setup > Battery > BATTERY CAPACITY IN Ah
Use this function to tell the Centric the total capacity (in ampere/hours) of the connected battery
strings. This total battery capacity figure is used by the Centric in three ways:
•
To provide an estimate of the remaining battery time, when the system is in battery mode.
•
To calculate the battery current limit.
•
To calculate the duration of the battery test.
If you do not know your battery capacity, look at one of the battery cells. The Ah rating of a
battery cell is usually indicated on the outside of the cell. This same number is your battery
capacity.
6.1.3.4 Setup > Battery > BATTERY TEMPERATURE CONTROL
These functions are related to battery temperature compensation, a process that monitors the
battery temperature and adjusts the charging voltage to avoid overcharging the battery. This
prolongs battery life.
6.1.3.4.1 Setup > Batt. > Batt. Temp. Cntl. >
TEMP SENSORS YES/NO
Indicate whether battery temperature sensors are present or not. Battery temperature sensors are
required if one wishes to make use of battery temperature compensation.
6.1.3.4.2 Setup > Batt. > Batt. Temp. Cntl. >
ENABLE/DISABLE BATT. TEMP. COMP.
Enables / disables battery temperature compensation.
6.1.3.4.3 Setup > Batt. > Batt. Temp. Cntl. >
BATT. TEMP. COMP. PARAMTERS
The ideal parameters can vary depending on the type of battery cells being used and their
manufacturer. Consult the battery manufacturer's data sheet for more information.
6.1.3.4.3.1 Temp. comp factor for a single cell
The compensation factor is usually provided on the battery manufacturer's data sheet.
6.1.3.4.3.2 Low limit dc voltage at compensation
Lowest charging voltage to be used when battery temperature compensation is enabled.
6.1.3.4.3.3 High limit dc voltage at compensation
Highest charging voltage to be used when battery temperature compensation is enabled.
