BMS10x0 Alternative Thermistor Input?

2 years 6 months ago #29533837 by G4mE_bRe4k3r
Currently looking at the BMS 10x0 for a battery monitoring system, and the option for thermistor inputs is what made this product attractive for our project. Instead of thermistor inputs, we are are using a fiber-optic temperature sensor and reading the temperature data from the batteries along the fiber length into labview and are going to convert that into an output that the BMS10x0 can read, however we are unsure as to what actions the BMS10x0 will perform upon receiving the data. What type/value should our signal output be so that the chip will recognize a certain voltage as a high temp reading, and what would the chip then do in regards to the overtemp response?

The temperature sensor inputs are recommended for the direct implementation of 10K NTC thermistors. The board natively calculates the temperature if these are implemented.

If you are using an external program for temperature monitoring, our recommended approach is to command the BMS using it's runtime command interface over serial or CAN. Right now, you should implement your control by sending an emergency stop (!EX) if your temperature is too high. We are currently still working on adding more commands, but sending an emergency stop command from Labview when your batteries are too hot is the recommended approach.
