———————————————————————————
Having done part of a month long European international road trip (so far covering ca 4000km), I find that abrp often is overly optimistic of he actual charging speeds, and I'd like an option to tweak it by a multiplier (e.g. 90% of ideal conditions/speed). Most of the stops I've done have really been quick when it comes to starting and stopping the charge, but in practice chargers have not performed as expected, for example many of the chargers in Spain are probably overheating due to not having any shade. Over a time sensitive 3000km drive I did this meant that the ca 15 charging stops all needed some 10-15min extra due to non-perfect charging curves, which ends up being hours incorrect estimation for a longer drive.
