Victron CAN-bus temperature sensor
Shipped in 1-3 days
The CAN bus temperature sensor from Victron Energy (mpn ass000200100) is a battery temperature sensor for the Buck Boost DC/DC converter series and an important accessory when they are connected to an LFP lithium battery. Temperature sensing is required when LFP lithium batteries are charged at low temperatures. The charging current of a lithium battery must be reduced when the battery temperature drops below 5 degrees and the charging current must be stopped when the temperature drops below zero degrees. The CAN bus temp. sensor takes care of this. It measures the temperature of the lithium battery and sends it to the buck-boost DC/DC converter. The buck-boost DC/DC converter reduces or stops the charging process when the battery temperature becomes too low.
In addition, the sensor can also be connected to the temperature sensor port of a Multi or Quattro so that the Multi or Quattro can reduce or stop charging when the battery temperature is too low.
Features
- Battery temperature monitoring
- Supply voltage 4.38 V/DC
- Current consumption 60 mA (at 13.6 V)
- Output for heavy user shutdown (frequent user)
- LED status indicators
- CAN.bus for control purposes and down/up converter or Quattro, MultiPlus and Venus GX communication
- Alarm output
Functionality
The CAN.bus temperature sensor is an accessory designed specifically for all models of buck-boost DC-DC converters. The temperature is transmitted to the converter via a communication cable through the CAN bus communication ports. The CAN.Bus temperature sensor can also be used in combination with any Victron Multi or Quattro. This allows the charging voltage to be controlled according to the low temperature.
For LiFePO4 lithium systems, this sensor is required in many system applications due to the fact that LiFePO4 batteries must not be charged when they are too cold. Charging lithium batteries at or around freezing will cause permanent damage to the cells.
