Open Chargeport What is it? As the name suggests, it's a transmitter that will open the charge port of a Model S. Last week I received my EU spec model S, and charged a few times with the cable Tesla supplies with the car. The button to open the Charge port door, really is a nice feature. As there is no such thing on a standard Type 2 charge cable, i now have to open the car door, touch the battery icon, and select open charge port. Not very convenient. Therefore i wanted to make my own transmitter that opens the chargeport, and that can be fitted into a standard Type2 plug. Credits to Banahogg who documented his attempts to analyze the RF data here which helped me finish this project in a few days. The components needed: I used a 433 Mhz module connected to a PIC microcontroller. (US model S, might require a 315Mhz module) Only a few other components are required. 1x PIC12F1822 microcontroller 1x TX-SAW MID/3V 1x Lithium cell, 3V 2x 100nf capacitor 1x 10uf capacitor 1x pushbutton Feel free to build your own Open Chargeport, or improve it. PIC sourcecode can be downloaded from Github: OpenChargeport The chip inside the Model S charge plug is a Si4010, i have made a version for this chip as well, will upload it to Github soon.
