2.4 Battery State of Charge (SOC)
2.4.1 Which device should I use for SOC calculation?
There are three products types that calculate State Of Charge (SOC). The CCGX itself does not
calculate SOC, it only retrieves it from the connected devices.
The three products that calculate SOC are:
Battery Monitors, such as the BMVs, the Lynx Shunt, or the Lynx Ion BMS
1.
Multi and Quattro inverter/chargers
2.
Batteries with built-in battery monitor and a (mostly CAN bus) connection to the CCGX.
3.
For some systems types it is necessary to use a dedicated battery monitor, such as a BMV or Lynx
Shunt VE.Can. For other systems it is not necessary.
Explaining the different system types one by one:
Battery and Multi or Quattro (a typical backup system)
No battery monitor is required: the Multi or Quattro is the only product connected to the battery and
has full control over all charge and discharge currents. Therefore it can calculate the correct SOC
itself.
Configuration:
Enable and configure the Battery Monitor in VEConfigure.
1.
In the CCGX, in Settings → System setup, verify the selected Battery Monitor. It should be set to
2.
the Multi or Quattro.
Battery with Multi or Quattro and MPPT Solar Chargers -ALSO- An EasySolar with CCGX built-in
No battery monitor is required, as long as all MPPT Solar Chargers are Victron products and are
connected to the CCGX. The CCGX will continuously read the actual charge current from all solar
chargers, and send the total to the Multi (or Quattro) which then uses that information in its SOC
calculations.
Configuration:
Enable and configure the Battery Monitor in VEConfigure.
1.
On the CCGX, in Settings → System setup, verify the selected Battery Monitor. It should be the
2.
Multi or Quattro.
In the same menu, verify that the option 'Use solar charger current to improve VE.Bus SOC' is
3.
enabled. Note that this is not a setting - it just an indicator of an automatic process.
Note that this feature requires recent firmware versions in both the Multis or Quattros (402 minimum),
and the CCGX (v2.06 minimum).
Batteries with a built-in battery monitor
In cases where the system includes a battery which has a built-in battery monitor and SOC calculation
- such as many of the batteries listed
here
- a dedicated battery monitor is not required.
