6.5.3.6 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.
6.5.3.7 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.
6.5.3.8 Fully Charged Current
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.
6.5.3.9 Fully Charged Time
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.
6.5.3.10Battery Temperature
In order for the DCM100 to properly determine battery capacity and state of charge, it must know the temperature of the battery If you are using a TR3K temperature sensor attached to the battery, you should set this parameter to “Sensor”. Otherwise, if no temperature sensor is available, you can set this parameter to the estimated battery temperature, between
6.5.3.11Time Remaining Floor
The DCM100 calculates the time, given the current being discharged from the battery, before the battery becomes discharged. By default, the DCM100 considers a battery to be discharged when its state of charge reaches the “Time Remaining Floor” value, which is by default set to 50%. If you desire to use some other state of charge value for the “Time Remaining Floor”, you may change this parameter to the desired value.
6.5.3.12Time Remaining Averaging Period
If loads on the battery are switching on and off frequently, the battery time remaining value calculated by the DCM100 can vary significantly. You may change the time over which current readings are averaged by changing this parameter anywhere in the range of 1 second to 32 minutes.
6.5.3.13Zero Current Threshold
The current sensor reading can drift slightly at zero current, depending on temperature. Over a long period of time, this can cause the DCM100 to calculate that a battery is discharging slowly, even though it is not. The Zero Current Threshold parameter indicates a reading from the current sensor below which no current is considered to be flowing into or out of the battery.
