General and Q&A

This is the weekly general LFE EVerest call for all topics not covered by the working groups. 

Chair: Robert de Leeuw

Meeting Notes:

11 January 2025

January 2025 stable release:

19 November 2024

Ted explained his plans for RPI daughterboards for development of CAN based MCS solution. Also explained the auxilary power function.

How they want to use EVerest to demonstrate 15118 over CAN works, making EVerest reference for other implementations.

12 November 2024

Shared important updates from the other working groups

• General and Q&A 

•  

  • CP LIN presented

• Cloud Communication

•  

  • Plan for OCPP 2.1 presented

  •  

    • Architectural restructuring: 

    •  

      • Class per Functional Block

•  

  • Loading configuration files

5 November 2024

Discussed upcomming change to the Framework. Currently each module reach the config file for settings. The prototype solution reads the config files once and each module gits its own setting provided from the framework. The modules themselves wont need changes.
Booting speed of EVerest is greatly improved.

Univerity of Daleware joined the call.
They are active in developing and prototyping different EV charging standards. They want to start contributing some of the work to EVerest.
Presentation of LIN CP. A lot of information shared. How to implement, hardware requirements/options. Advantages etc etc.
They also develop hardware that they might open source.

21 May 2024

1. New member introductions

a) Tweede golf: Dutch Software firm, Planning OpenADR 3.0 client Open Source, possible as contribution to EVerest.Inspired by increasing grid congestion in the Netherlands. Wanted to get more involved in the energy space and studied where the were gaps in terms of Open Source implementations. Found EEBus and OpenADR as the most interesting and chose to start with OpenADR 3.0 for now.Planning to contribute in Rust.

b) Kris Singh from Heliox. Using libOCPP to implement OCPP2.0.1 and soon OCPP 1.6 too

2. Open discussion topics:

• Anyone already using OpenADR or has use cases?
  Qwello is planning to use OpenADR on the Cloud side.
  Enel X (Italian utility) has advertised OpenADR compliance on their "Juicebox" chargers in the US in the past.

07 May 2024:
1. Discussion on meeting frequency: Proposal to go bi-weekly accepted

02 April 2024

1. EVerest news: Upcoming Updated Contribution Guideline (will be published in Zulip)

2. Community Update: 
@Roger Bedell added rudimentary ISO 15118-20 ACDP support to evlibiso15118 in the branch evlibiso15118_with_ACD
https://github.com/cienporcien/evlibiso15118/tree/evlibiso15118_with_ACDP

It works with this branch of libiso15118 in the branch dash-20-poc-acdp that contains the EVSE side of ACDP.
https://github.com/cienporcien/libiso15118/tree/dash-20-poc-acdp 

There is also a simple implementation of SDP for Wireless in both of these.

Still lacking is an ACDP module, PPD module, and an ISO15118-8 wifi module and interfacing these to libiso15118 and evlibiso15118.

Discussion: Rust or C++ for Roger's modules.Roger will connect with Holger offline to investigate using Rust

• Dan: send Robert list of PR to discuss in Cloud call.

6 February 2024

• Action Item: Robert: Put sending signed meter values on Cloud Communication call agenda.

• LED strip HMI: should this be part of EVerest? Currently seen as a customization on top of EVerest.

• Where to discuss release, time of releases and pull requests. Use the "Everest" Stream in Zulip. For a call it will be the General and Q&A call.

• When new multi repo pull requests or larger feather change is coming. Please start a discussion on Zulip and align with the maintainers so we can streamline and plan the work.

• Agreed with proposed way of working for meeting minutes. Use hackmd for now as note taking tool and store them on the EVerest wiki.

• Action Item: Piet: Nudge Cornelius for the ISRA Meter, Evgeny is going to work on a pull request this week.
