If only someone had done all this work years ago and posted it on video and forum.... The sdu current sensors are Melexis Mlx91209ca exact same as on the model 3 drive units. Usually in stock at mouser.
Oh Damien you are a saviour. The embarrassing thing is that I watched your video where you explained how you damaged one sensor and I was sure that I can avoid it but did it in the end too😢
I had a look on Mouser and Digikey and unfortunately 7.3mV/mT version is out of stock but they have 19mV/mT. Did I understand correctly that this version could be reprogrammed to have required sensitivity?
@@LatutaEV hmmm possibly but, and i'm just spit balling here, what if there was another way? what if there was some mechanism in some sort of opensource software to allow ANY current sensor to be calibrated using a know dc current and just adjusting a value on some sort of web interface? pfffftt crazy...
I watch all these type videos and everything Damien does because I hope at some point to be able to build one for myself. I think the first thing I will do is just go ahead and order new sensors and have them on hand and not even try to remove the others. I have desoldered things in the past but I always used a braid to pull the solder and I don't know if that would work at all on this stuff. Good luck with it Latuta EV.
The difficulty in this case is that the PCB is covered with a protective coat. You can remove the top one but you can't access the bottom one until you unsolder the bottom one. If I were to do this again I would just cut them as high up as possible and would solder to the new board with solder overflow perhaps
Yes me too 🤣 as I was really feeling down and thought tha I ruined my "cheap" but still rather expensive Tesla motor. I thought what if Tesla uses some custom sensor you can't find anywhere. I was such a relief to find that it could be purchased 😅
Too bad you didn't give to some proffesional shop to unsolder it.. I wouldnt dare to do that by my self if is to risky. As I can see, you knew it is risky. I hope you will get sensors
The main issue is that the Tesla board is covered with the thick layer of protective lacquer and even with hot air chance of braking the sensor is high

I thought so 🤣
@@LatutaEV I'm not sure if it helps but I searched for 7.3mV/mT and found as-electronic seems to have them in stock.

@@LatutaEV thanks, that will help.
I hope Damiens suggestion works for you.
I'll keep watching with interest. 🙂

U got this !
Thanks I hope so☺️
What about current sensors from Toyota or Honda contactor boards? Gotta look at diagrams
Well I am hoping I could find what sensors Tesla use
Wow that sucks. Have you thought about trying to drive it with a different inverter you already have?
Yes I have to say that I am so gutted I decided to leave it for a while and keep looking for a replacement sensor
Too bad you didn't give to some proffesional shop to unsolder it.. I wouldnt dare to do that by my self if is to risky. As I can see, you knew it is risky. I hope you will get sensors
Yes you are right that was very stupid of me.
I should have at least got hot air station and used that
@@LatutaEV yes, hot air station at least
