Yes, the highest charge speed is only realised under 50%. There's a charge curve graphic posted earlier from memory.Best charge speed I have seen is 140kw on a Tesla charger, only up to 50% after this it drops off to 70kw until I reached about 80% then speed drops off again. No preheating of the battery, ambient temp in double digits.
With my NMC battery "77" ER the max is 144kW, a "64" LR tops off at 140kW and the LFP "51" SR only does 88kW.
I regularly see 144kW on Tesla and RAA (Kempower hardware) chargers when charging from a low SoC. Never with a Tritium hardware charger.
Past 80% charging is really slow. You really shouldn't use a DCFC past that unless you really need the extra few percent to be sure of reaching the next charger.
You're just wasting time and potentially holding up other people waiting.
