my 2014 BMW i3 could be set to start charging when electricity was cheap (defined by me onscreen). it was a little buggy, as far as systems go, but it was the original model year (for north america, i think 2013 in europe).

A lot of newer charging stations in the US also have this built in, as well. You can hook them up to the internet, or do it manually. How mine works is pretty clever: you plug it in, and it asks you if you'd like to go to 100% now or wait until charging is cheaper. If you don't reply, it will fast charge your car to about 40%, and then wait.

that's EXACTLY the oversight in the 2013-2014 onboard firmware :

even though i didn't need a full charge at 8am, the car would realize it couldn't get to (the not important) full charge by 8am, which was the previous day time of departure, and would start charging while electricity was still expensive, because it decided maximal charge at previous day departure time was more important than cheap electricity.

Just an oversight...

Sounds like a software/firmware fix. Did they never adjust that logic? queue my hatred for automotive closed ecosystem abandonware

Nope, but perhaps in later model year software builds.
