The Victron CAN-bus Temperature Sensor is a battery temperature sensor for the Victron Buck-Boost DC/DC converter range and is an essential accessory when the Buck-Boost DC/DC converter is connected to a Lithium-ion Phosphate 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 the charge when the battery temperature drops too low.
In addition to this, the CAN-bus Temp. The 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.
