I drove a Hyundai IONIQ 5 Dynamiq base model (on media loan for a week to review) South West, from Sydney to Evie Networks 350kW charging station at Sutton Forest.
My aim was to test if this EV can achieve the promised 10% to 80% in 18 minutes during Winter, which is the most challenging time of year for an EV to fast charge.
Hyundai says that when connected to an 800V ultra-rapid charger, the IONIQ 5 can recharge from 10% to 80% in 18 minutes*.
This is the same charging speed claim as other electric cars built on the Hyundai E-GMP platform eg: Kia EV6, Hyundai Ioniq 6, Genesis GV60.
The * detail is that the charging time may increase if peak charging rates are not achieved. Charging time will also be dependent on the condition and durability of the high voltage battery, charger specifications and ambient temperature at point of use.
I would add another note that it is unlikely you would be able to achieve 10% to 80% in 18 minutes if the car battery was still cold and hadn’t driven far before the charge was started.
For background I drove over 150km to the charger location starting at an altitude of about 60m in Sydney and climbing to an altitude of 656m at Sutton Forest West.
The temperature at the destination was 16C and the test was done Sydney mid-Winter on July 14th.
The charge started at 11% / 45km left on the car range guess-o-meter and finished at 100% with estimated 540km range.
My suggestion based on this test is don’t bother charging a Hyundai Ioniq at a 350kW fast charger past 84% unless you really really need the range or need a longer break from driving eg: to finish lunch, otherwise you’re wasting 20 minutes of driving time.
