Hardware recommendations
Cornelius Claussen
Hi Romain,
check out the open hardware design here which can be used as-is or as a start for own hardware design:
You can also buy those boards or a full charger from Pionix.
Or you have a look at chargebyte, the chargecontrol C for AC charging is supported as well.
Porting to other hardware is usually relatively simple as long as the charger runs on linux and you can replace that Linux with your own variant, so if you have something already let us know and we can help!
If you want to build your own hardware, you will need a Homeplug GreenPHY compatible PLC chip that can do SLAC for high level comms.
There is few options at the moment, the most common one being QCA7000/7005 which is available as hardware module from several vendors (driver for SPI included in Linux mainline).
A new quite nice alternative is Lumisil which is also supported by everest, this chip is available on most chip distributors.
In addition you need some computer (e.g. raspberry pi 4) and control pilot circuitry (look at the reference schematics for that)

Hello and thank you for the awesome works done with Everest.Is it possible to update the hardware recommendations, including plc modem specifications for combo CCS / iso 5118 ?Many thanksRomainE55C

Hi Cornelius,
Many thanks for your fast and clear answer.
I will contact you about the Pionix board.

Hi Cornelius,
I'm trying to run everest on a raspberry pi on my own charger, and I don't want to use the ISO 15118 functionality but instead I will use the a cdm and pwm to communicate with the ocpp via usb port connecting to the raspberry pi. Do you have any suggestions on what steps I could follow in order to do that?
Thanks
Evan

Hi Evan,
not sure if I get the question right. What is cdm? For AC just using PWM is totally fine, ISO-15118-2 on AC is supported by EVerest by not by most cars, so you can safely disable that. OCPP requires a network connection, so if you want to use USB you could use a USB-ETH adapter to connect via ethernet to the Pi. Is that what you a looking for?
