Re: Model 3 High Voltage Controller

EDIT: Adjusted number of amps I pulled to 30. Attached file instead of broken google drive link.

ORIGINAL:
I have pulled around 30 amps at HV_UP.
Any update on this? I'm not aware of any amp draw limitations. I'm also using mine for off grid solar battery, not EV.

Also, if it's helpful to anyone ...

Re: Model 3 High Voltage Controller

You'll need to modify the pins based on the board you're using.

Re: Model 3 High Voltage Controller

I don't believe you need 0x6F2 for the model 3. I was able to get it to work on the model 3 battery without it. You do need to modify the code in the sketch though.

I think it's a model S specific code.

Re: Model 3 High Voltage Controller

Thanks to the help of everyone on this forum and especially bielec, I was able to get HV contact closure. I did indeed need a capacitor connected to the output of the HV lines of the battery.

I now have 2 issues I'm wondering if anyone else has encoutered. They may be related.

1) The HV contactors ...

Re: Model 3 High Voltage Controller


I now have contact closure! I needed a capacitor across the HV output presumably to satisfy the charge up time of the precharge process.
The contactors take a lot of current at the start and the dcdc converter puts out a lot of voltage too, I saw almost 20v across the battery terminals for a ...

Re: Tesla Model 3 Battery Hacking

Hello,
Any experience with HVIL (High Voltage Interlock Loop) issues on model 3 battery pack?

I have a full tesla model 3 battery pack from a salvaged car. Besides replacing pyro fuse, no internal modifications.

I've used raspberry pi zero and evtv candue to send and read messages from battery ...
