Battery state of charge indicator
8.5.1 Battery monitor (if present)
This instrument allows you to monitor the boat energy consumptions and gives useful information for keeping an eye on the
state of charge of the batteries. Depending on the increase in charging voltage and the decrease in charging current, it is
possible to establish whether the battery is fully charged or not.
Instrument readings:
V Battery voltage : this reading is useful for estimating the approximate state of charge of the battery. A 12V battery is
considered discharged when it cannot maintain a voltage of 10,5 V in charging conditions.
I Current: this represents the actual current flow of the battery, input or output. A discharge current is shown by a negative
reading (output current from the battery).
CE Consumed energy: shows the quantity of Ah consumed by the battery. For a fully charged battery this value is equal to
0,0 A (synchronized system). If the battery absorbs a 12 A current for 3 hours, this value is equal to –36,0 Ah.
SOC State of charge: this is the ideal indicator for checking the actual charge level of the battery. The reading shows the
amount of residual energy actually present in the battery. A fully charged battery will show a reading of 100,0%. A completely
discharged battery will show a reading of 0.0%.
TTG Time to go: this is an estimate of how long the battery can supply the present load before requiring a recharge.
Full charge
When the battery voltage exceeds a certain level during a preset period and the charge current is lower than a certain level in
the same period, the battery may be considered fully charged. These preset levels of voltage, current and duration are called
“Fully Charged Parameters”. In general, for 24V acid batteries, the voltage charge parameter is 26,4V, whereas the current
charge parameter amounts to 1% of the battery total capacity (for example, 2A for a 200 Ah battery). A charge time
parameter of 3 minutes is sufficient for most batteries.
8.5.1.1 Synchronization of the device
In order to have a reliable reading, the state of charge displayed by the battery control device and the actual charge level of
the battery must be continually synchronized. This can be done by fully charging the battery so that the instrument will
automatically read the new status of fully charged.
If necessary, the instrument may also be synchronized manually (in other words, set on “full battery charge”).
Synchronization may be obtained, after having fully charged the battery, in normal mode by holding down simultaneously
buttons + and - for 3 seconds, or in configuration mode by using the SYNC option (see instrument instructions manual).
If the instrument does not synchronize itself automatically, check that the values of charged voltage, tail current and charge
time have been configured correctly. When the voltage supply to the BMV is interrupted, the battery control device must
be synchronized again before starting to work again correctly.
