About the AcCCS PCB

AcCCS is an open source PCB design by IdahoLabResearch, published on GitHub under the MIT license. It is a 2-layer board measuring 172.1 × 143.5 mm, with 106 components from 37 distinct parts.

Other key parts include the TLC555CP, LM6132BIN/NOPB, MCP23008-XP and SFH617A-1. By type, the board carries 40 resistors, 25 diodes, 14 transistors, 8 ICs, 8 connectors and 5 relays.

It belongs with the dev boards & breakouts designs in this gallery.

From the project

A collection of tools and scripts used to communicate and emulate Electric Vehicle Communication Controllers (EVCC) and Supply Equipment Communication Controllers (SECC).

This project is the result of our efforts to find COTS hardware and existing open source software capable of communicating via HomePlug GreenPHY (HPGP) with CCS enabled vehicles and charging stations. We are providing some basic scripts to emulate an EV (see PEV.py) or an EVSE (see EVSE.py). These two scripts utilize a third-party open source project that provide Scapy packet definitions for Layer 2 (HPGP - layerscapy). Our goal was to establish a persistent network connection with a target device so that we can test the device for network vulnerabilities.
