2024-10-16 Meeting notes

Dev Update

  • Summary Testival France 2024:
    • DIN70121 & ISO15118-2 worked like expected. 
    • ISO15118-2 PnC: Most PnC sessions have worked. There were two bugs that we were able to fix at the Testival.
    • Several successful ISO15118-20 dynamic mode sessions. There were some TLS1.3 problems and an exi decode error

Question form Roger - Testing also against MCS? - No MCS type there

  • everest-core:
    • Multiplexer module for ISO communication - merged
    • Limit to ev_max_current/voltage if target is higher - merged
    • TLS server certificate_sha_1 calculated incorrect hash - merged
    • Testival findings converted in PRs:
      • D20 dynamic mode
      • Openssl Tls key logging support
      • Some small hotfixes
  • libiso15118:
    • Adding basic dynamic mode PR in review
  • cbexigen:
    • Fix compiler warnings in generated c code - merged
    • Add a functionality to download the XSD schema files from the ISO website - merged
    • Use big int for integer type without max value - reviewed and requested changes

Aligned on roadmap: 

Today

  • ISO 15118-2 / DIN SPEC 70121 implementation ISO 15118-2 DC BPT (SAE J2847/2)
  • C++ based ISO 15118-20 for EVSE side (EXI + state machine) for DC & DC BPT
  • beta release DC & DC BPT (native C++)
  • car simulator for ISO 15118-20 (based on JOSEV community edition)

Q4/24

  • ISO-2 / ISO-20 / DIN /… mux module
  • stable release DC & DC BPT
  • beta release AC & AC BPT (native C++)
  • dynamic mode
  • ISO15118-20 PnC

Q1/25

  • beta release missing ISO15118-20 components: schedule renegotiation, pause/resume, etc.
  • car simulator natively in EVerest
  • MCS based on HIL

H2/25

  • MCS charging vehicles

TBD, work started

ISO 15118-8 (Wifi communication)

Car simulator in EVerest - how to reuse Rogers work for that?

Also for ACDP and -8 evslac replacement - where to fit this in?

→ Discussion in one of the next meetings, probably Mid-November

2024-10-02 Meeting notes

Feature Freeze:

  • Some issues found during testing.
  • Second release candidate 2024.9.0-rc2 coming soon

Updated Roadmap

  • Tweaked the roadmap slightly.
  • Added MCS


Discussed MCS shortly:

  • Specs not final yet.
  • New hardware needed, PWM circuit changed

2024-09-18 Meeting Notes

Participants: (tbd)

Development update:

Open PRs / Issues:

cbexigen:

needs more testing, Moritz will try to work on that again

needs more testing, not mcuh prio roght now

But fix in lbcbv2g should get into decoder

libcbv2g issue:

Compiler warnings while compiling in Windows - maybe establish default compiler warnings

MCS

A lot of new faces in the call, partly from SAE, focus on MCS 

Goal: Get more input into EVerest as a reference solution

Open topic - should we establish a new working group focussed on MCS or have a dedicated MCS meetings on the car comm WG?

Question from Roger:

WIll PIONIX work on an EV side implementation / board?

→ Possibly, need smth to test anyways

So far no other boards available currently (ABB or analog devices)

CCS to MCS difference not that big - some amendments needed

Access to MCS draft currently only to CHarIN committee members
