Victron | Buck-Boost DC/DC Converters + Temp. Sensor

DC-DC Converter for charging a 12/24V service battery in vehicles with an intelligent dynamo. 

The Buck-Boost DC-DC Converter is a DC-DC converter for charging a 12/24V service battery in vehicles with an intelligent dynamo. Since, when the engine is running, these dynamos (powered by the on-board electronics of Euro 5 and 6 engines) do not always emit the correct charging current, a DC-DC converter is essential for charging the service battery properly.

The CAN-bus Temp. Sensor is a battery temperature sensor for the Buck-Boost DC/DC converter range and is an essential accessory when the Buck-Boost DC/DC converter is connected to a LFP lithium battery.

Temperature sensing is needed when LFP lithium batteries are charged at low temperatures. The charge current to a lithium battery has to be reduced once the battery temperature drops below 5 degrees and the charge current has to stop when the temperature drops below zero.

The CAN-bus Temp. Sensor takes care of this. It measures the lithium battery temperature and sends this to the Buck-Boost DC/DC converter. The Buck-Boost DC/DC converter will reduce or stop charge when the battery temperature drops too low.

In addition to this, the CAN-bus Temp. Sensor can also be connected to the temperature sensor terminal in a Multi or Quattro, so the Multi or Quattro can reduce or stop charging when the battery temperature drops too low.
