I did, but was not able to get below 3,5V... The car refused to drive, and shut down the heater, was only blowing cold air in.

Hi, I tried the described procedure now, and at first it seemed to work. I drove the car down to zero bars, then disconnected the 12V- battery and conected it again. After starting it up the car had two bars showing. I was able to do this 5 times, but after that disconecting and connecting the...

Hi Johannes, I don't have them for sale, but you can order from JLCPCB. They offer PCBs at a great price for such projects. You will need the Gerberfiles to order from them; I can create them for you if you are not familiar with PCB design software. BR

This was the bit of information that I needed, thank you! I will repeat this process and deplete them down to below 3V. I didn't think of disconnection the 12V, but it is a great idea! No wonder theBMS is still behaving strangely: But I must say that these small electric vehicles are a great...

I just finished discharging the traction battery. I let the car running until it shut down the heater, and then let it run until it stopped moving. This is the state of the cells: I think the state of the cells is pretty good; the voltages are all pretty close together. What do you think...

Not yet; I don't have a github account; But I can do this too, so it will not be lost for those who need the files.

I made two boards for mounting the AD202KY One mounts horizontally to the existing holes on the main PCB, the other one is mounted vertically, and will need so glue for preventing damage due to vibrations. As my inverter is already running in the car again I can not test it now, but maybe...

[Mod Edit: removed incorrect board layouts] I made two boards for mounting the AD202KY One mounts horizontally to the existing holes on the main PCB, the other one is mounted vertically, and will need so glue for preventing damage due to vibrations. As my inverter is already running in the car...

Yeah, I think that this is the Problem on my car. Calculated SOC is not alligning with the cells voltage. So I tried to get the car as empty as possible, but a low SOC might not be enough for the procedure to start. Can I damage Something, like the car not accepting charging anymore when i let...

I wanted to give a quick update. I was ablöe to get HobDrive running, and copuld see that the ECU was measuring a difference of 20V between the BMS and the inverter. So I figured that the Hybrid- board is defective on my car too. On saturday I took out the inverter from the car, and opened it...

Yes, the other fixes seem to use the AD202KN instead of the KY type. The only difference is that mine is a SIP (singel-inline-package) instead of a DIP (dual-inline- package) Eletrically they are identical as far as I can see. so this should not be a problem. I wanted to make a custom board to...

I've seen those posts (read the whole thread!) and this is great. However what I miss is the measurements of the pins from the hybrid- board. Whith these measurements I could redraw the outline of the old hybrid- board and insert the new AD202, and make a board which can simply be soldered in...

Some good, and some not so good news. I got HobDrive started yesterday by using my old phone. Seems to have a problem with the new android version or something. Connecting was easy using rationald videos; thanks for that! Now to the bad news: I could not get the car to start, and always got the...

I just downloaded HobDrive (full version) but can not get it to start; It will show the start screen, then after some seconds close and go back to the home screen. I am using an android phone; Oneplus Nord 2 CE lite. Any suggestions? BR

I got them used, from a guy who was dismantelling his emergency- power- supply. I paid 19€ per cell, which still is over 1600€ for the whole pack. But since the car was essentially free (got it for repairing the OBC) I figured it was worth a try. The old ones had started to inflate quite...
