Its worth remembering ioniqs only do 20 – 80% in 15min on a 350kW charger and there ain’t many about!
The ioniq 5 takes around 25 minutes on a 150Kw charger
Alot of Stellantis group EV’s have upto 100kW DC charging speed so 10 to 80% is around 30, 35 minutes. The 2023 Kia Niro DC charging speed is 72kW and takes around 45 minutes.
The Atto 3 with its max 88kW DC charging speed for 10 -80% charge takes aroud 40 minutes. So its not to dissimilar to its rivals.
