Hey @frenck, as home-assistant/core#91081 got merged into 2023.5 (thanks!), this should also be included.

Also, I was wondering if home-assistant/core#88759 and home-assistant/core#91081 could be seen as noteworthy change, as BMW/Mini EV owners now are able to control vehicle charging from HA.

It seems that this PR is targeted against an incorrect branch since it has a parent PR on one of our codebases. Documentation that needs to be updated for an upcoming release should target the next branch. Please change the target branch of this PR to next and rebase if needed.
