ISO15118 support is distributed accross multiple repositories and modules in EVerest. Please see the following references of other ISO15118 related development:
- Some functionality of part 2 of ISO 15118 is integrated in the EvseManager module in the everest-core repository.
- Current development for an EXI code generator (as used in the ISO 15118 protocol suite) is ongoing in the cbexigen repository.
- The repository libSlac contains definitions of SLAC messages that are used for ISO 15118 communication.
- DIN70121 & ISO15118-2 funcationality can be found in EVerest module EvseV2G
