Imagine your battery charge level at say 40%, and you want to top up to 75% for the next leg of your journey. So you plug in to a 150kw or 350kw DC fast charger and head off to grab some lunch or do a bit of shopping.
Returning a bit later, the battery is at 95% - far higher than you intended. As commonly happens, the car was ready to go before you were.
It would be very useful - and just a software change - to let us set a charge limit when DC fast charging, just like we do when AC charging at home. Mercedes does it, Tesla does it, as do others. Dear Porsche: Please add this feature!! And then have the app ping me when I get close to my desired charge level.
Here's the Tesla version, showing a 90% charge limit set on a Model Y and being used at a Supercharger station:
