So, I think I can now claim to have the most complete CAN protocol documentation for the Huawei R48xx power supply/charger (with the exception of Huawei themselves maybe).

For this, I've gathered/summarized information from various forum posts, several implementations, blog articles, messing around myself and probably-should-not-be-public documentation.
