Monitoring the temperature of every cell to maximize safety and
For comparison, if only neighboring cell 3 had a temperature sensor, the BMS would not detect a similar failure until 5 minutes later (figure 4). If the temperature sensor was two cells away on cell 6, the delay would increase to over 10 minutes. If the threshold was higher, at 70°C, the neighboring cells would never have set off the alarm.

MultiPlus: Disable Charger based on battery temperature
My current setup is to connect the BMV-702 Temperature Control Sensor to the Battery and then connected the BMV-702 Relay to the MultiPlus AUX1 which controls the Charger via the Charge Assistant. It would be nice if the new function can OR switch the charge off, OR switch the charger to float. When the temperature falls below this
MultiPlus 12/3000/120-50 120 Temperature Sense error and Battery
Latest firmware. I have a Victron Battery Monitor BMV-712 with a separate temperature sensor connected to it and DVCC enabled in Cerbo GX. The Cerbo always selects the BM temp sensor when selection is set to "Automatic". The temp sense warning comes up randomly regardless of the charger state ( connected to AC, disconnected to AC, inverting).

What Temperature sensor can I use with the Cerbo?
Hi An old topic but a have a related question. If I want to monitor temperature in eg.g. the engine compartment. Which sensor can I use for that. The one mentioned above seems to be for battery mounting (ASS000001000). Can these be used as well ASS560002005 Or anything else but not a battery mount version?

Low temperatute cut off?
As I know, the LiFepo4 battery can afford low temp even below 0℃ to -40℃, can you equip a customized BMS to prevent the low-temperature condition? such as protection of cut-off at 5℃ or -5℃, or you can set the alarm of specific temp.
Battery temp in Cerbo GX
You''d an connect a temp sensor to the battery terminal and then to one of the Cerbo temperature inputs. The VE.Bus BMS does not have any tempuse sensor. The sensors are inside the battery and the battery sends a temperature disconnect signal to the VE.Bus BMS through the three pin contour that daisy chains between the VE.Bus BMS and all the batteries.
Battery Temperature Reporting
Loaded the new 3.50 GUI-v2 release and spotted the Battery Temp shown in the Battery tile. Just like in VRM Dashboard for a long time. All good, I like it. Trouble is, in both cases it''s not the Temp from the managed batteries, it''s coming from a Multiplus sensor that''s been repurposed. And it makes no difference if the Multi is deselected as one of the battery
Built-in (low) temp sensor SmartSolar MPPT
the internal temperature sensor of the MPPT is only for temperature compensation (primarily used for lead acid batteries) and cannot be used to trigger the MPPT to shut off in case of low temperature. To make the MPPT shut off in case of low temperature of your Lithium battery you can set up a VE.Smart Network, connect your MPPT and at least a
Low temp shut off with no temp sensor!
Nope, should never need low temp cutoff (and I don''t have a temperature sensor installed). The IP22 is on 3.42, the MPPT 100/30 is on 1.61. Both I had turned off low temp cut off, not sure how it got turned back on on the IP22. It must have somehow got back to the default Li ion settings which has it set for 5 deg.

LiFePo4, BMS without low temperature battery cutoff
why a low temp cut off just buy a 12v thermostatic heater, to keep the battery warm but a temp sensor into the shunt and a ve smart network would work with the MPPT SmartSolar 100/20, and the Orion-Tr Smart 12/12-30 A, how new is the Blue Smart Charger 12-15A (newer ones should work with it too)
Multiplus battery temp sensor fault
I had a similar issue with a MultiPlus 12-2000 where the temperature sensor would suddenly, at random times, read extremely high temperatures and throw warnings and errors. I replaced the sensor but the problems remained. I then connected both temp sensor at the same battery pole and wired the old one to the VenusGX.

What happens if a battery temperature sensor fails?
For this reason, when the battery temperature sensor fails, it can cause problems not only for the battery, but the entire electrical system as well. When the battery temperature sensor fails, the vehicle will usually produce a few symptoms that can notify the driver that a problem has occurred and should be serviced. 1. Engine surging
How do I remove the temperature sensor from the battery?
Put the old batteries in a vice and twist the plastic housing away from it and the battery breaks out . The top connectors just push out too so there you have a temperature sensor and something else that attaches to the side of the batteries . I left the temp sensor there but the other thing does not seem to affect charging .
