EVs on the Hyundai Motor Group’s E-GMP platform are usually charging monsters. The Hyundai Ioniq 5 can knock out a 10-80% fast-charging session in about 20 minutes, which is faster than most high-end luxurious vehicles can handle. The Kia EV6 and EV9 are equally spectacular. However now that the all-new three-row Hyundai Ioniq 9 is hitting the streets, so how does it stack up?
On first blush, the outcomes look good. In a take a look at by The Ioniq Manthe Ioniq 9 charged from 10-80% in beneath 24 minutes, which is true in keeping with Hyundai’s claimed charging velocity. That included a peak charging charge of 243 kilowatts, which is fairly spectacular.
However you will not see these numbers all over the place. The Ioniq 9 is the primary all-new Hyundai product to return from the manufacturing unit with a Tesla-style North American Charging System (NACS) port. That provides it native entry to Tesla Superchargers, however with one massive caveat: The Ioniq 9 will take far longer to cost on a Tesla charger.
That is the results of Hyundai’s best charging benefit, its 800-volt structure. Cranking the voltage permits you deal with extra wattage (i.e. energy) with much less present and warmth, making 800- or 1,000-volt vehicles just like the Ioniq 5, Ioniq 9, Lucid Gravity and Porsche Taycan charging champs. But most EVs use lower-voltage platforms, with primarily 400-volt elements which can be extra commonplace and cheaper. That is what the Tesla Mannequin 3, Mannequin S, Mannequin X and Mannequin Y use, which is why it is also what Tesla Superchargers use.

While you attempt to cost an 800-volt system with a 400-volt chargers, issues get sophisticated. (Word that we speak about voltages by class, however nominal voltages are exact figures. So whereas a Tesla charger is taken into account to be within the 400-volt class, it operates at 480 volts. Equally, whereas the Ioniq 9’s platform is an 800-volt-class system, it operates at round 610 volts.)
For the automotive to just accept the facility from the charger, it must step up the voltage utilizing inside DC-to-DC converters, that are lossy and never at all times highly effective sufficient to max out your charging velocity.
The top outcome: Slower cost occasions on Superchargers, as Tim Levin explains right here.
The Ioniq Man’s take a look at was carried out on a 350-kilowatt Electrify America station, which natively helps 800-volt programs. That is the best-case state of affairs. It is also what will probably be accessible as soon as 1,000-volt Tesla Superchargers and native NACS dispensers come on-line, which ought to occur quickly. However within the meantime, Ioniq 9 house owners will see slower cost occasions on Superchargers. How a lot slower? For that, you will want to attend for the official InsideEVs cost take a look at, coming quickly.
