2.4 The different battery state-of-charge display options
The BMV can display both the Amp-hours removed (compensated for
charge efficiency only) and the actual state-of-charge (compensated
for charge efficiency and Peukert efficiency). Reading the state-of-
charge is the best way to monitor the battery. This parameter is given
in percentages, where 100 % represents a fully charged battery and
0 % a completely flat battery. You can compare this with a fuel-gauge
in a car.
The BMV also estimates how long the battery can support the present
load ("time-to-go" readout). This is actually the time left until the battery
is completely discharged. If the battery load is fluctuating heavily it is
best not to rely on this reading too much since it is a momentary
readout and must be used as a guideline only. We always encourage
the use of the state-of-charge readout for accurate battery monitoring.
2.5 Features of the BMV
The BMV is available in 3 models, each of which addresses a different
set of requirements. The supported features of each model are
outlined in the following table.
Comprehensive monitoring of a
single battery
Basic monitoring of a second
(starter) battery
Use of alternate shunts
Automatic detection of nominal
system voltage.
Suitable for high voltage systems.
Serial communications interface
(PC-Link).
