X. Battery Synchronization
1. Partial synchronization
For a reliable readout, the Device’s state of charge (SoC) has to be synchronized regularly to the actual state
of the battery. This procedure, called Partial Synchronization, is accomplished by fully charging the battery
(you don’t need to run the Partial Synchronization manually).
The Device recognizes the Battery as fully charged when the following «charged criteria» are met: a)
battery voltage exceeds the set Charged Voltage parameter value, and simultaneously b) charging current
falls below the set Charged Current value during the c) time period specified as Charged Period value
(see Section IX for details). When the Partial Synchronization is finished, the Device’s LED indicates this
with a series of four GREEN signals (see Section VII), state of charge will be set to 100% and the consumed
Ah will be set to 0Ah.
Calculations must be on to perform the Partial Synchronization (command YD:CALCS ON or CALCS=ON
in the YDBM.TXT file, see Section IX).
To keep the calculated SoC value credible, we recommend you to perform Partial Synchronization at least
once a month. The more frequently you fully charge your battery, the more credible the Device readings.
If the Device does not synchronise automatically, the Charged Voltage, Charged Current, and Charged
Period may need adjustment. When the Device has been disconnected from power or the battery,
the Partial Synchronization should be done before the Device can operate correctly. Another scenario
that requires Partial Synchronization is the first connection of a Device to a battery which is not fully
charged.
2. Full synchronization
Full Synchronization updates the state of health (SoH) value. It is long process which requires about 24
hours and special care concerning the discharge current. You should keep the Device connected to both
the battery and the NMEA 2000 power source throughout the entire process without a single interruption.
Otherwise, you will have to start the procedure again.
