BENEFITS OF THE BATTERY MONITORING SYSTEM
The Intelligent Battery Monitoring System informs you about
the current energy status, allowing you to plan your energy
supply making it the key element of the vehicle’s energy
management.
By using the Intelligent Battery Monitoring System, the energy
management system can react quickly in case of critical battery
state which influences both the consumer behaviour and the
alternator.
It delivers real time measurements during the
charging/discharging processes, preventing phenomena like
over charging or over temperature which can lead to a
shortened life for your batteries.
DESIGN AND FUNCTION
The IBS is attached directly to the negative pole of the battery
via its pole terminal.
Alongside the terminal, the mechanical portion of the battery
sensor consists of the shunt and grounding bolt.
The shunt is attached to the vehicle’s load path and is used as a
measuring resistor to measure the current indirectly.
THE ALL-IN-ONE INSTRUMENT
The VL Flex device can easily be configured to be the
instrument you need - thanks to its sun-readable 1.44” TFT
display embedded into a standard 52 mm instrument housing.
The supported analog inputs allow you to directly read from
your level sensors and the Intelligent Battery Sensor can be
read through the LIN 2.0 interface.
The simple but effective graphic design can be set up in a single
or dual layout, presenting the data in a clear and intuitive form,
while the colored bar graph and the alarm display allow you to
visually understand your data.
CONTACTLESS CONFIGURATION (Patent Pending)
Thanks to the contactless configuration you can setup your all-
in-one instrument with a simple tap!
Launch the companion App and define your settings through
the user-friendly interface, then simply hold your mobile device
in proximity of the VL Flex device to transfer the configuration.
Thanks to the embedded passive antenna the configuration can
be done powerless!

CONFIGURATION
B001025
CONFIGURATION
INTELLIGENT BATTERY MONITOR APP
To configure the IBM system, some parameters must be
calibrated, like the gauge type, the sensor and its calibration or
the warning threshold.
This is possible through the “VL Flex Configurator” smartphone
App, which can be downloaded free of charge from the stores
of both Android and iOS devices.
A simple and detailed explanation of the configuration process
is also available as in-app instructions.
Thanks to the passive embedded NFC receiver, the VL Flex 52
can be configured, as described below, without the need of
power supply.
INTELLIGENT BATTERY
MONITOR APP
The VL Flex Configurator App
(Intelligent Battery Monitor) is
available for both iOS and
Android devices.
The setup of the VL Flex device is an intuitive three-step
process.
Please remember that you must READ from the device before
being able to manipulate and download the configuration to
the instrument.
1. READ
2. CONFIGURATE
3. WRITE

CONFIGURATION
B001025
SYSTEMCONFIGURATION
1. READ THE VL FLEX CONFIGURATION
Launch the “Intelligent Battery Monitor” App and
read the actual configuration of the device by
“tapping” the smartphone onto the front lens.
The READ operation is mandatory before the WRITE
operation is allowed.
After the readout, the App will be set with the
current VL Flex configuration.
NOTE: The antenna position on the smartphone
depends on the model.
Please refer to the smartphone manufacturer manual.
2. CONFIGURE BATTERY PARAMETERS
Use the first box to define which IBS is used.
For the IBS Sensor to correctly work the type of
battery must be defined. Use the second box to
choose this parameter.
Write the batteries capacity in the last field of this
section.
NOTE: The type of the battery and its capacity can be
found printed on the batteries housing.
3. CONFIGURE THE LEVEL SENSOR (OPTIONAL)
Check the Resistive Input Switch in order to
configurate the VL Flex depending on your Level
Sensor.
The first field is for defining, weather a Fuel Level
Sensor or a Fresh Water Level Sensor is used.
In the second field you must choose the resistance
values of the used sensor.
NOTE: The sensors resistor values depend on the
Model.
Please refer to the sensor manufacturer manual.

CONFIGURATION
B001025
4. SETUP THE ALARMS
You can activate or deactivate the alarms by using the
App switches.
Use the field next to the switch, to define the value,
at which the alarm should be triggered.
5. CUSTOMIZE BACKLIGHT LEVELS AND UNITS
You can complete the VL Flex configuration with the
“Settings” tab.
In this section it is possible to adjust the Day and
Night backlight intensity through the dedicated App
slider.
Here you can also choose your preferred unit for the
temperature measurements. (Celsius or Fahrenheit)
6. DOWNLOAD THE CONFIGURATION TO THE VL FLEX
Once the configuration is completed, you can download it to the
VL Flex.
Press the “APPLY” button on the top/right corner of
the App and near the smartphone to the VL Flex lens
as shown in picture.

CONFIGURATION
B001025
SUPPORTED CONFIGURATIOS
*the supported configurations may be updated at any time. Please make sure to always use the latest App version.
TIME FOR VALID SOC AND SOH
The State Of Charge (SOC) and State Of Health (SOH) values are
to be considered valid after power on of the system, 3.5 hours
of “quiescent” time and valid battery parameters.
“Quiescent” time means that the current consumption of the
vehicle electrical system has to be for the whole recalibration
time (3.5 hours) between -100mA and 0mA.
If there is a discharge peak during this time (e.g. radio turned
on, etc.) the time for SOC recalibration will be longer than 3.5
hours.
If there is an additional power on of the IBS sensor (e.g. IBS
disconnected from the battery, or from the Link Up gateway)
then the recalibration time of 3.5 hours starts again.
EXTERNAL CHARGING OF THE BATTERY
If the battery is charged by an external power supply, it is
important that the connection of the external charger is done
properly.
If the connection is performed incorrectly, the IBS will not be
able to measure the charge current and it will not calculate the
SOC correctly.
Please connect the positive clamp of the charger to the battery
pole and the negative clamp of the charger device to the IBS
ground connection (where the vehicle ground is connected),
and not directly to the negative pole of the battery.
The charging current must flow through the IBS so it can
correctly determine the charge balance.
