Fastned recently opened its first few 175 kW fast chargers in the Netherlands and performed an interesting comparative test on the Hyundai IONIQ Electric.
As it turns out, the IONIQ Electric can be charged 50% quicker (to 80%) from the higher power chargers than from an ordinary 50 kW unit. This is due to the fact that the car itself can accept 60-70 kW.
That makes charging much less time consuming.
"Charging the Hyundai Ioniq at our stations now ~50% faster because of new generation of 175 kW chargers. Quite a difference & this marks just the beginning of a global race towards MUCH faster charging... ⚡️"
