Also - I know it may be a slip of the keyboard, but it's worth understanding (and being pedantic about) the difference between kW and kWh especially as the charger is charging at 50kW, but probably delivering about 50kWh of charge to get a 5LR from 0-80%ish, the numbers are close enough to be confusing.
Sure, some people say 'yeah, but it's roughly the same' but to put that into context, if I got that wrong with MpH and said 'I find that when I have done 75 Miles it really hits the battery' but I actually meant '75MpH' - clearly it's quite different, and 'could' cause confusion. (although in your case it was still pretty clear what you meant.) A few people will pipe up and correct you on here, but that's generally because it makes it easier for them to help you rather than them just being an a$$hat, (in fact, other than a plethora of 10mm spanners there seems to be a distinct lack of tools on this little corner of the internet. Makes a quite pleasant change)
Just remember that kW works the opposite way round to miles. In simple (and technically not entirely correct but close enough to understand) terms:
kW is the speed at which the power is moving (be it from charger to battery, or battery to motor). - so the 'speed in Miles per Hour' equivalent.
kWh is the amount of power that was delivered during your charge (or used during your drive).- so the ''distance in Miles' equivalent.
So, if you travel at 10 mph for an hour, you'll travel 10 miles. If you charge at 10kW for an hour, you'll put 10kWh into the battery.
