How A Tesla Supercharger Works With The 2025 Hyundai Ioniq 5

The 2025 Hyundai Ioniq 5 comes from the manufacturing facility with a Tesla-style NACS plug, the primary non-Tesla to make use of that format.
It would nonetheless pull the fast-charging speeds the Ioniq 5 is known for. However efficiency shall be totally different on the Tesla Superchargers because of their voltage variations. 
Utilizing an adapter for normal CCS quick chargers will not have an effect on speeds, nevertheless. 

Whenever you purchase a Hyundai Ioniq 5, you are getting plenty of automobile. For years now, it has been one of many most-awarded and top-ranked electrical automobiles for its mixture of vary, fashion and efficiency. However arguably the coup de grâce has been its fast-charging prowess. Like different automobiles on the Hyundai Motor Group’s E-GMP platform, the Ioniq 5 is able to utilizing a number of the strongest DC quick chargers round, and may use them to rocket from a ten% cost to 80% in simply 18 minutes. 

So when Hyundai determined that the newly American-made 2025 Ioniq 5 would use a Tesla-style North American Charging Normal (NACS) plug from the manufacturing facility, this introduced engineers with an fascinating drawback: how do they get the automobile to carry out the identical means if it used a Tesla Supercharger?  

In a briefing with InsideEVs and different journalists a number of weeks in the past, Hyundai Motor America engineers mentioned they’re assured they pulled it off. And that whereas Ioniq 5 homeowners will not get the crazy-fast charging speeds they’re accustomed to in the event that they use Tesla’s Supercharger community, they will nonetheless be impressed, and different DC quick chargers will work in addition to they at all times have. 

“There may be a whole division in Ann Arbor that works on charging and research this,” Hyundai spokesperson Miles Johnson mentioned on the briefing. If the Ioniq 5 did not cost in addition to everybody anticipated, he mentioned, “We would not be placing these things out. It has to work, and it must be at our ranges and at our customary.”

How The 2025 Hyundai Ioniq 5 Expenses 

The charging speeds for the up to date American-spec Ioniq 5—which is now the primary non-Tesla EV to make use of a Tesla-style plug from the manufacturing facility—breaks down like this.

There are actually two methods to fast-charge the EV. House owners can plug in natively at a Tesla Supercharger station only a Tesla Mannequin Y or Cybertruck proprietor would. Once they do, the height charging fee they’ll see on most Superchargers (the V3 ones, particularly) they’ll see most speeds of 135 kW. That ought to take the Ioniq 5 from 10% to 80% in 24 minutes if the automobile has the smaller 63 kWh battery pack.

On the bigger battery pack most Ioniq 5 trim ranges can have, a Tesla Supercharger will take it from 10% to 80% in 29 minutes.

The opposite option to fast-charge is to make use of one other adapter—this one for Mixed Charging System (CCS) plugs, which characterize most non-Tesla plugs on the market from Electrify America and different suppliers. Lots of these now provide quicker charging speeds than Tesla’s community does.

Utilizing the CCS adapter, Ioniq 5 homeowners will see speeds of as much as 257 kW once they use a 350 kW DC quick charger. That ought to take the automobile from 10% to 80% in 20 minutes, no matter their battery measurement. And it is proper in step with the efficiency of the earlier Ioniq 5 on a CCS fast-charger. 

In different phrases, “the adapter doesn’t have an effect on the charging velocity,” mentioned Karl Holodnick, Engineering Supervisor for Propulsion and Charging at Hyundai America’s Technical Heart. Furthermore, he mentioned, the 2025 Ioniq 5 will truly be quicker to cost on the Tesla community than the previous automobiles did once they used the Tesla Magic Dock stations. These maxed out round 99 kW, however now they will hit speeds there of as much as 135 kW. “There are some variations within the battery design, the place we’re capable of cost at a better present now,” Holodnick mentioned.  

So if this bears out, the 2025 Ioniq 5 will keep its fame as one of many quickest-charging EVs in its class—if not the quickest. By comparability, a equally priced Chevrolet Equinox EV can settle for DC fast-charging as much as simply 150 kW and in our testing will solely go from 20% to 80% in 35 minutes. Equally, a Tesla Mannequin Y can often cost from 10% to 80% in roughly 27 minutes on a Tesla 250 kW charger. 

The brand new Tesla NACS-equipped Ioniq 5s will include a CCS adapter, whereas present Ioniq 5 homeowners will have the ability to buy a Tesla-style adapter for his or her automobiles quickly too. Extra particulars on the latter are coming quickly, Hyundai officers mentioned, however they anticipate all present homeowners to get their adapters and have the ability to entry the Tesla community within the first quarter of 2025. When the 2025 Ioniq 5 launches, it will likely be prepared from the begin to  use the Tesla community.

As for plug-and-charge, the characteristic that permits Tesla homeowners to seamlessly roll as much as a charger and pay routinely from a web-based account with out twiddling with some smartphone app, that’s at present below improvement. 

“We’re engaged on all these integration items to make that attainable,” mentioned Ian Tupper, the Senior Group Supervisor of Strategic Environmental Partnerships at Hyundai. “At first, our homeowners of the mannequin yr 25 Ioniq 5 must use the Tesla app to cost, however we’re additionally including the charging characteristic to the Hyundai app as effectively.” 

The 2025 Ioniq 5 will even be able to vehicle-to-load (V2L) bidirectional charging like previous fashions, which permits it to energy different units and even total properties if wanted. And like previous automobiles, that can work by way of an exterior adapter that works with the brand new NACS plug.

It isn’t instantly clear if automobiles just like the Kia EV6 or Genesis GV60, which use the identical {hardware} because the Ioniq 5 and can launch comparable adapters after which NACS plugs quickly, will supply the identical efficiency or not. Presumably, this information offers us a good suggestion of what to anticipate from these automobiles.

What’s The Distinction?

For newcomers to the EV world—individuals used to pulling as much as a gasoline station, (hopefully) realizing which octane to decide on after which merely driving off after the pump is completed—the world of charging curves, kilowatt hours and plug varieties can really feel confounding. 

It is a part of why the entire American auto trade is transferring to Tesla’s plug customary, now formally extra referred to as SAE J3400. After Ford first negotiated a deal for its EVs to make use of Tesla’s charging community after which change to its plug, different carmakers shortly adopted, fed up with the unreliable and inconsistent experiences at present EV charging networks. Tesla’s Supercharger community just isn’t solely the biggest one, but additionally broadly thought of the most effective.

A part of that high quality, nevertheless, was as a result of Tesla famously controls the complete {hardware} and software program expertise for automobiles and chargers from prime to backside. Getting different kinds of EVs—which use many alternative batteries, software program setups and so forth—to make use of the Tesla community equally has been a problem at occasions. Furthermore, the change to NACS plugs and Tesla Supercharger entry has been delayed at a number of moments this yr, reportedly partially after Tesla’s charging staff layoffs this spring. 

However there’s been one other problem for the engineers behind EVs just like the Ioniq 5: voltage. Merely put, that is the ability that “pushes” electrical energy, and it applies to each the automobiles themselves and their chargers.

The Hyundai Ioniq 5 and a lot of the otehr Hyundai E-GMP automobiles are 800-volt EVs. Only some others are proper now, just like the Porsche Taycan and Lucid Air, though the entire trade is regularly transferring in that route. Most different EVs are able to 400 volts—lengthy the trade customary. And most Tesla fashions (save for the brand new Cybertruck) are 350 or 400 volt EVs. 

The Tesla Supercharger community was designed for these automobiles. Most of them run round 500 volts, Hyundai officers mentioned. However Hyundai’s personal EVs are able to quicker charging speeds partially due to their increased voltage scores. In different phrases, it was a problem for engineers to get an Ioniq 5 to carry out on a Tesla Supercharger as it’d on a 350-kW Electrify America station. 

And with most speeds of 135 kW on a Tesla Supercharger, they will not, Hyundai officers mentioned. However that is simply what the Tesla chargers are able to when it comes to velocity and voltage. Nonetheless, with the ability to go from 10% to 80% in 29 minutes for a automobile with as much as 318 miles of vary remains to be fairly respectable, and seemingly about what a comparable Mannequin Y can do anyway. 

We stay up for testing the NACS-equipped 2025 Ioniq 5 on the Tesla Superchargers and different charging platforms as quickly as we get our palms on one. However for now, for individuals who wish to use the Tesla community but wish to personal one thing that is not a Tesla, these early outcomes appear promising.
