does anybody have the detail information,
about the procedures over CAN-Messages,
to switch on/off the contactors inside the 85 kWh battery pack of the TESLA Model S.

I dont know of anyone who has done it. I have tried. You need the correct CAN data and you need to figure out the HVIL system. Instead I opened it, replaced the contactors with contactors that I control.

Thaks!


The HVIL is solved with a 180 Ohm resistor between X036/11 and X035/10.

See the JPEG in the attachement.


Next, I will spending moor time to analyse the appropriate CAN Msgs to swith on the contactors.

Your solution will be plan B.
