When used with Multi- inverter/chargers the dongle provides on-battery temperature and voltage
sensing capabilities - allowing compensation for possible cable losses which can occur during charging
and discharging. Temperature sensing allows accurate temperature-compensation during battery
charge cycles. The dongle is, at present, the only way to add an “on-battery” sensing capability to the
MultiPlus-II models, if they are not also connected to a GX device and CANbus battery.
The dongle can be used in systems with or without a GX device - such as the CCGX. In systems with a
GX device, and another source of temperature and voltage data (eg from a CANbus battery), the
CCGX data will override temperature and voltage information from the dongle. In this role the dongle
will still provide live-information via its VictronConnect interface; and it will provide firmware updates
without requiring an internet connection.
When the dongle is used in systems which do not have a
GX device, the dongle's voltage and
temperature data becomes the primary source of that information, and can be used by other
connected devices for voltage compensation.
In systems with a Multiplus-II, dongle and
GX device, but no other source of temperature and voltage,
the data from the dongle will also be used.
At this time, the VE.Bus Smart dongle cannot send its temperature and voltage data as part of a
VE.Smart network.
The VE.Bus Smart dongle is able to sense battery temperature in two ways: The default method is the
dongle's on-board temperature sensor. When the dongle is mounted directly onto the battery case
(using its adhesive attachment) it will sense the battery temperature directly from the battery casing.
The second method - which provides improved battery temperature sensing - is available by using an
optional battery-terminal mounted sensor. When this sensor is connected, the default sensor is
overridden and the dongle will use this method instead.
