3. GENERAL OPERATION
In normal operating mode the BMV-501 can display the six most
important parameters of your DC system. Use the < and > selection keys
to select the desired parameter.
Battery voltage (V). This readout is useful to make a rough
estimation of the battery’s state-of-charge. A 12V battery is
considered empty when it can’t maintain a voltage of
10.5V
under load conditions.
Current (A) represents the actual current flowing in or out of
the battery. A discharge current is indicated as a negative
value (current flowing out of the battery). If for example a DC
to AC inverter draws 5Amps from the battery, it will be
displayed as
–5.0A .
Consumed Amphours (Ah) displays the amount of Amphours
consumed from the battery. A fully charged battery sets this
readout to
0.0Ah (synchronized system). When for three
hours a current of 12Amps is drawn from the battery, this
readout gives
–36.0Ah .
State-of-charge (%). This is the best way to monitor the actual
state of the battery. This readout represents the current
amount of energy left in the battery. A fully charged battery
sets this readout to
100.0% while a fully discharged battery is
represented as 0.0% .
Time-to-go (h) is an estimation of how long the battery can
support the present load, before it needs recharging. This
time will be represented in hours (above 100h) or in hh.mm
format (under 100h). A time-to-go of 15 hours and 45 minutes
will be represented as
15.45h .
Temperature (
°
C) displays the present battery temperature.
This readout is automatically activated when Function F11 is
set to
AU and the optional temperature sensor is connected to
the BMV-501. When connection with the temperature sensor
is lost, the display will return four dashes (- - - -).
