Hello, I have a Cupra Born 170KW 77/82 KWH,
I went multiple times to a 300 KW fast charger, but the charging speed started from ~50KW - 63KW maximum.
It to took
1 hour and 30 minutes from 19% to 100%
55 minutes from 42% to 80%
Is it normal to be limited to maximum ~63KW ?
Cupra born charging speed ?

You need to be < 10% and have a warm battery to achieve the maximum charging speeds in my experience. I've seen up to 150kW
2023 Cupra Born, 77kWh eBoost, 5 seats, Aurora Blue, 19" Copper Typhoon, Pilot L + TPA, Tech L w/SAFE, AR-HUD.
Take a look at the charging curve.

You only get the top charging speeds up to 20% then it drops off steadily up to 80% when it falls off a cliff. There is no point trying to fast charge over 80% it’s quicker to head off and charge again once it drops (unless you need the 100%). Other factors such as outside temp or how busy the chargers are can also influence things.

I always find it's optimal to start from about 2-6% as the battery is warm by the time it is hitting peak charging curve. Also some rapid acceleration and deceleration if you are not around a lot of traffic helps warm up the battery pre charge. I usually get between 135kW - 175kW at 14% and then it drops slowly after there to about 100kW at 50%
Certain "350kW" charging stations seem to be limited in any situation... such as Gridserve Strensham northbound, which has a string of complaints all telling the same story on Zapmap. One thing to note is generally any chargers claiming to be over 250kW such as a Tesla 250kW... are only 175kW max at 400V - 350kW refers to the max load at 800V for high voltage 800V systems such as the Kia EV6. The Born runs on 400V
Try looking on Zapmap at the charging station you visited. If there is a string of people also having limited power at around the same kW, then it's probably the charger.
19% is pretty high too to start charging and by the time your battery is warmed up from the pathetic 67kW going through it, it will be at the point in the charging curve where you cannot charge higher than that anyway
Hope that helps. What temperature was it outside, and how long were you driving for to get to the charger?
This is the most my car ever peaked at... for a few seconds after it dropped back down pretty fast
