So I've had a first look at the Tesla Gen 2 10Kw charger. Now , making one of these work as is with CAN messages is near on impossible due to the level of integration of the charger and the car. So I decided to have a look inside. Seems it uses 3 x 3.5kw modules linked back to a central logic board. Each modules connects to the logic pcb with 8 wires.
So far i have identified GND , +12v , +5v and a 500k canbus. Two lines seems to carry analog signals and one seems to be open circuit. Attached see some CAN captures from this internal network. I may be wrong but I bet it will be easier to work out these messages and get the individual charger modules to wake up.
So plan is to design a little breakout board so I can monitor the signals on a live car during the charge process and log the CAN messages.
Stay tuned
