The Peukert coefcient allows the actual capacity
of a battery to be estimated. For example, a ca-
pacity of 100Ah is applicable for a C/20 discharge
rate, i.e. 5A per hour for 20 hours at an ambient
temperature of 20°C. However, this same battery
will provide less than 100Ah if the amperage used
exceeds 5A, or more if the amperage is lower.
It is therefore an intelligent battery management
system, which is able to automatically adapt to
any consumption or charge on one or two house
batteries, in such a way as to provide an extre-
mely precise indication of the remaining charge
percentage.
The BATVIEW2 is easy to connect and automatical-
ly recognises a 12V DC or 24V DC supply voltage
when it is powered on.
The BATVIEW2 is equipped with a non-volatile me-
mory allowing the conguration settings to be
stored, even when there is no power, when it is
reactivated.
The BATVIEW2 is not sensitive to cycling effects as
it automatically detects oating mode, which
means that the batteries are fully charged. It is
therefore not affected by measurement drift over
the course of successive charging and dischar-
ging cycles, which, for other management sys-
tems on the market, results in a need to comple-
tely reinitialise the charge status.
The shunt supplied is made from a special alloy,
which allows a voltage drop, calibrated in mV
(converted into amps by the management sys-
tem), to be measured. This value is etched on the
shunt as is the maximum amperage that can ow
through it. This maximum amperage is 300A for a
maximum of 5 minutes. The permanent ampera-
ge that can ow through this type of shunt is two
thirds of this value (200A).
GENERAL CHARACTERISTICS
The BATVIEW2 is a battery management system
that allows the voltage of 4 different sets of batte-
ries and the amperage of 2 different sets of bat-
teries to be measured (1 shunt supplied, a second
optional shunt is available).
A calculation algorithm based on the Peukert
exponent allows the charge percentage for two
sets of batteries to be displayed (if a second op-
tional shunt is used).

INFLUENCE OF THE PEUKERT EXPONENT:
The Peukert exponent allows the life of a bat-
tery, which is not linear, to be better estimated.
In the example opposite, for a 350A bat-
tery, with a discharge capacity of 20 hours
(C20) stated by the battery manufacturers,
we could actually expect use of 17.5A per
hour for 20 hours (in green on the graph).
If this discharge was linear, it could be argued
that in 10 hours we could obtain 35A per hour, ex-
cept that in reality, the result is 9 hours, the Peukert
exponent allowing this to be determined. The re-
maining capacity, according to the BATVIEW2, ex-
pressed as a charge percentage, is therefore as
accurate as possible compared with the reality.

INSTALLATION GUIDE
List of terminals PRECAUTIONS TO BE TAKEN FOR INSTALLATION
4Allconnection errors(polarityreversalsinparticu-
lar) cause irreversible damage to the equipment.
Youshould,therefore,payparticularattentiontothis.
4For the measuring wires for each shunt (ri-
ght hand terminal 1&2, 9&10), use a shielded
twisted pair cable (otherwise there is a risk of
measurement being frozen), tin-plated with ring
terminals (Ø 4 mm). Use the same pair for the 2
measuring screws (– and +) for the same shunt.
4A cross-section of 1 mm2, if possible tin-pla-
ted, is recommended for the other connected
wires. The use of shielded cable is not necessa-
ry in this case, except if there is the potential for
disturbance by the wiring for other equipment.
4 The external shunt for current measure-
ment must be positioned as close as possible
to the positive on the battery, i.e. the + BAT.
4An error in the direction of the 2 jumper wires
between one of the shunts and the BATVIEW2 will
result in an error in the direction of the current, i.e.
an arrow pointing down during charging and up
during discharging, as well as incorrect informa-
tion on the quantity of power remaining. Simply
reverse the 2 wires in question in order to restore
the correct direction and resolve the problem.

IMPORTANT when rst powered on
Disregard the initial information provided on the
basis of factory settings.
Adjust the type and capacity settings for different
sets (see SETTINGS MODE).
For increased accuracy when measuring current,
it is necessary to reset the current. To do this, en-
sure that no current is owing through the shunt
or shunts (no battery power consumption or char-
ging in progress).
Disconnect then reconnect the BATVIEW2.
The BATVIEW2 produces an estimate of the remai-
ning capacity, in Ah, by measuring the no-load
voltage of the batteries. This is only an initial esti-
mate.
To completely initialise the device, simply per-
form a rst charging cycle, preferably by using
the built-in charger. 100% initialisation becomes
effective once the batteries have been charged
(VBAT > 13.2V or 13.6V depending on the chosen
technology and once the charging current has
been reduced to zero).

Factory settings are operational until the user en-
ters his/her own settings.
To save any changes, quit by pressing and holding
the SET button. The conguration settings are sa-
ved in a non-volatile memory, as a replacement
for the factory settings.
These settings will, therefore, be automatically
applied when the device is next powered on.
It should be noted that the device automatically
leaves settings mode 45 seconds after the last
time the SET button is pressed without saving the
modied settings in a memory.

tects
4An undervoltage fault on any one of the 4 sets
of batteries.
4An overvoltage fault on any one of the 4 sets
of batteries.
4A temperature fault on sets 1 or 2.
4A low capacity fault on sets 1 or 2.
This mode is signalled by a ashing display indica-
ting the type of fault detected.
This mode results in the closure of an RCT dry loop
(terminals 1, 2, 3). The maximum switchable cur-
rent for the dry loop relay is 1A at 36V DC max.:
Return to “Normal” mode is automatic as soon as
the fault has disappeared.
Pressing “SET” allows you to momentarily return
(for 10 seconds) to “Normal” mode to allow you
to view various settings. If the fault persists, a re-
turn to “Alarm” mode is automatic.
