The full story
The Open Vehicle Monitoring System already supported the Maxus eDeliver 3 electric van, but only older models with NMC battery packs. Newer vans use CATL LFP packs, and this pull request adds support for them.
The contributor, who earlier sent OVMS code for a Renault Twizy, had already reverse engineered the van's CAN and UDS frames with others on the GoingElectric forum. They say most of the new code was written by Claude, based on the old code and their own ESPHome Maxus project.
