New BBSHD Temperature Sensor? BBSHD + Phaserunner + V3 setup

I got a new BBSHD and hooking it up to a cycle analyst v3/phaserunner setup.

My old BBSHD setup went fine with the temp sensor in the V3 as a 10k thermistor but this new one definitely does not have a 10k. It seems Bafang is using a totally different thermistor all together.

Before I start testing and plotting temp data, does anyone know what kind of thermistor is in the new BBSHD? What settings on the cycle analyst did you use?

Thank you for the help!
 
First post. Excuse the noob. I have a new BBSHD from Luba and have installed the phaserunner and CA3 to a fat bike. Everything works perfectly except the temp. I’ve done extensive research and can’t solve the temperature issues. At room temp I show +/- 0.88v (65F). It’s like likely not a 10K thermistor and the 3.19V output from thermistor the Grin Two person bike install is not what I get. Sooo we have new BBSHD with another type of thermistor. I don’t even k ow the input voltage. Good luck.

If you figure this out please share.
 
I have the same issue. The older BBSHDs had a 10K thermistor. I wrote to Grin about that andit seems the nes BBSHD have a new type of sensor. They had a few complaints but have no solution for now. Since I'm doing the bike for someone else and lack the knowledge to figure it out, I will put a 10k thermistor from Grin in the motor, hook it up and call it a day.

I guess it's 1k thermistor or some thermocouple. I wish I was more helpful, I hope somebody with the right knowledge will find a solution soon!
 
Today, I replaced the original thermistor with a 10k thermistor from Grin. The operation was simple and the acces to the thermistor is easy once the stator's removed. To fix the thermistor to the stator, I used Permatex Ultra Black sealant. Since it's not full of acid like other RTV silicones which smell like vinegar, it's safe to use for this aplication and it won't loose "tackiness" like hot glue if the temperature goes above 100C.

I was then able to program the Cycle Analyst with the temp sensor (10k and not linear). The original temp sensor does not seem to be a thermocouple, no voltage comes out of it.

hope this helps, it was the fastest solution for me
