Figure 9-1, Ending Battery Voltage Versus Time
The battery’s state of charge—which is the best indicator of the condition of the batteries—is
indicated on the METER: 05A BMK SOC display. This display shows that the batteries are fully
charged (i.e., SOC = 100%) once the following three conditions have been met:
1. The charging voltage has stabilized over a period of time (see Figure 9-1).
2. The charging current has decreased to a low % of the AHr capacity—normally less than 2%.
3. The AHrs that were removed from the battery are within 1% of fully being returned.
When the BMK sense module is fi rst connected, the batteries will need to be fully charged (i.e.,
SOC = 100%) at least once to establish a SOC reference point. While this reference point is being
calculated, the METER: 05A BMK SOC display shows “ Think’n ” to indicate that the SOC reference
point is calculated. After the batteries are fully charged, the display changes from “ Think’n ” to
“ 100% ” and begins to provide accurate SOC percentage values. After the batteries have reached
100% SOC and have discharged ≥ 0.5% of the battery capacity setting, the charge ef fi ciency
value is recalculated and the Amp Hours In/Out read-out resets to the recalculated value.
Info: To help maintain accuracy of the METER: 05A BMK SOC display and keep the
batteries in good condition, they must be charged to 100% occasionally (~x1/week).
9.2.2 BMK METER Menu Items (with ME-ARTR)
From the BMK Home screen, press the METER button, and then turn the SELECT knob on the
ME-ARTR router to access the different meters that determine the status of the battery system.
Info: If multiple BMKs are connected, the System Home screen displays information
from the BMK connected to the LOWEST numbered port. For example, if a BMK is
connected to the network port on an inverter which is connected to Port 1 (P1Acc), and
another BMK is connected to Port 5 on the router (P5), the System Home screen will
show the information from the BMK connected to P1Acc.
METER: 05A BMK SOC
This read only menu either displays the calculated battery SOC (State of Charge) for the connected
battery bank, “Think’n” (to indicate the SOC is being calculated), or identi fi es a fault condition.
Note: Refer to Section 9.2.4 for information on BMK statuses/faults.
