off grid tesla car

[Mr Norman]

# 1 .on the plug that supplies the dc power to the tesla car, which holes are for the dc, #2 how many amps at dc can the car handle , on the low side ;say 80 amps to 200 amps .#3 what dc voltage can it handle on the lowside say 20v dc on up.#4 are there other prongs.that just monitor the voltage dc going in ? thanks Norman.

What you're looking to do won't work for a couple reasons.

The battery pack has 2 contactors built into it, meaning that unless the car sends a CAN message to the battery module the contactors won't close and you won't have any HV power on the cars wiring. You could root the MCU and send your own commands or use a CAN sniffer/injector but even then the car monitors the HV draw and it'll detect there's a higher than normal discharge rate and open the contactors.

More importantly the charging plug has 2 modes. AC where the power will get routed through the cars inverter and converted to DC (Level 1/2 charging) and DC mode where the battery power is directly exposed to the same wires (AC/DC inverter is not connected in this mode) and the pack is charged at at 400V/250A.

Because the pack is wired in series directly hooking up to the DC side will get you upwards to 350V+
