charging and travel times

Hyundai Ioniq 5 is aimed at those who want to travel long distances on the highway using only the power of electric motors. A mission that does not scare him with his recharging powers.

The super test, what is it? This is a new test format on Automobile-Propre.com, which follows the first impressions collected during the initial handling. This is an elaboration worthy of the greatest speleologists performed over much longer distances and always on the same route according to a very precise protocol, which is intended to be repeated with each novelty. We had started this exercise with plug-in hybrids and we are now also using a development dedicated to electrical. The goal? Collect comprehensive information from a long-term test under real conditions!

Feel free to suggest other questions in the comments to this new section!

Impressive, the Hyundai Ioniq 5 does not like cramped areas. This is especially the case in the city, where, like all SUVs, it is quickly limited. Yet this is where it consumes the least. On a secondary road, its efficiency is still interesting, but its damping has some shortcomings on bumpy roads, while being a little too flexible on its supports. On the other hand, on the highway, it is imperial. Traveling there on board is only a formality.

Charging curve for Hyundai Ioniq 5: a “useful” full in 18 minutes

Ioniq 5 hits hard when it comes to recharging. The built-in 11 kW AC charger is complemented by a maximum power of 220 kW, with an actual peak recorded at 223 kW during one of our tests (Ionity terminal at 54% SoC).

But as we had already been able to observe before without ever measuring it, Ioniq 5 rarely presents the same charging curve despite similar arrival conditions in front of the terminal (trip of one hundred kilometers on the highway before, similar outdoor temperature …). Thus, on a Fastned terminal, the curve began to fall from 45%, where it was necessary to wait in 55% before seeing the first level appear on an Ionity terminal. While the power collapses from 170 kW to 111 kW between 60% and 65% on the yellow terminal, it keeps its head above water at Ionity to slowly reach 115 kW at 80% load. The rumor that the powers of the Ionity terminals are lower to better bill the customer falls into the water (besides, we have never noticed this phenomenon).

In any case, the Ioniq 5 keeps its promises perfectly with powerful plateaus that allow it to do 10-80% in exactly 18 minutes. Barely enough time to take advantage of the Zero-Gravity seats. Unless you decide to charge a little more to cover several kilometers before the next charging solution, as it will take 10 minutes more to reach 90%, then another 18 minutes to reach 90-100%. But let’s specify here that the Ioniq 5 has a strange characteristic: between 82 and 83% load, the power drops to 7 kW in 3 minutes. While we were thinking about a breakdown, it is in fact a security procedure where the system checks the health of the cells after such a powerful recharge.

Autonomy regained: 241 km autonomy in 30 minutes

On the highway, we therefore measured a total autonomy of 298 km, or 208 km at a full “useful” from 10 to 80% load. When it comes to autonomy achieved per. minute recharge, Ioniq breaks 5 records. Only 15 minutes is enough to regain 166 km of autonomy taking into account the consumption, which serves as our reference, while 265 km in 45 minutes is possible. At this point, there are only a few minutes left to fill up 100%.

Note in passing that the autonomy indicator on the dashboard is quite reliable. Our various measurements on the motorway showed a% / km ratio very close to the current fuel consumption. At 100%, the counter showed ranges of 300 km and 297 km, which corresponds to the total range we measured. Also note that the computer is becoming more and more pessimistic as the SoC crashes to prevent the driver from getting into trouble.

How much do Hyundai Ioniq 5 charges cost?

At the time of this test, Ionity was still practicing its pricing policy per. minute. A stroke of luck for the crossover that fell is replenished just as quickly as its shadow. Recharging which from 10 to 80% represented a price of € 14.22 to the public price of € 0.79 / min. With the Ionity Premium subscription (€ 13 / month) the price drops to € 0.29 / min, ie. a total bill of… € 5.22! With an achieved range of 208 km, this represents an average cost of 2.51 € / 100 km on the motorway. Charging at home for a mixed trip would cost more …

But Ionity per minute is like Capri: it’s over. You have to pay per consumed kWh this summer with a public price of 0.69 € / kWh or 0.29 € / kWh with the subscription. This will be a game-changer for owners of this vehicle. For with an average of 52.8 kWh delivered by the fast terminals (actual 50.82 kWh according to the net capacity), useful charging would represent € 15.31 at best or € 36.43 at worst. That’s almost what we had at the Fastned terminals (0.59 € / kWh), with a total of € 31.33 for a recharge of 53.1 kWh according to their meter.

On-board route planner, ABRP and ChargeMap: an Ioniq 5 with deficiencies

With a vehicle with such a long range, you have time to find a charging station before you break down. But route planners are still important for traveling with peace of mind without having to search for a terminal. By programming the built-in GPS on Ioniq 5, it effectively informs us that the destination is out of range of the calculated autonomy. It then offers to access the station search menu.

But even with a sufficient charge to cover 300 km of autonomy, the system continues to identify the stations around the car. With each test, it was therefore only natural for the unit to target terminals within a radius of 150 km to … 200 m. And this with choices that regularly do not fit the picture of the many local AC terminals or at dealers of competing brands. Shame. For this test trip, we will therefore rely on our own estimates.

The autonomy of the Ioniq 5 allows us to go far, it is with a full tank that we decide to leave (98%) to target the Ionity station in Lochères 250 km away, where we arrive with 10% charge back. To make a full 100% charge that would have allowed us to end the journey and cross the finish line just below the 20% mark, our final goal. But the operation is not profitable in terms of time. We therefore decide to recharge to 70% in 15 minutes before driving on the road again. It was at the Darvault station, just over 430 km away, that we decided to make a short top-up that goes from 8% to 40% (8 minutes). Enough for us to pass the 500 km mark with 19% charge left.

This journey of 500 km thus required a total time of 4 hours 51 minutes with in detail 4 hours 20 minutes drive, 23 minutes recharging and 8 minutes development in the fixed price areas. It is our fastest route so far. Note that if we had decided to recharge to 100% in the Lochères area, which actually allowed us to cross the finish line with 17% charge left, the total recharge time (including ski passes) would be 49 minutes.

Hyundai Ioniq 5

On the application side, there are two strategies. ABRP provides two stops at the same areas that we have chosen, with roughly similar recharges, albeit a little pessimistic in terms of overall time. Overall, the ChargeMap is more accurate with very similar run and charge times as ours. But the application here selects three stops at charging speeds that do not allow you to utilize the full power of the Hyundai Ioniq 5. In addition, the system envisions shorter charging times of 2 to 3 minutes per second. compared to what we observed. With 10 minutes too much in its estimate, however, ABRP is doing better here.

With this strategy, we have minimized the time consumption at the terminal as much as possible. In the Darvault area, where we usually prepare the accounts, this represents a direct cost of € 6.67 with Hyundai’s Ionity Premium subscription. In the event that a full recharge had to be made at a domestic outlet on arrival, this would bring the total cost up to almost € 17, or just under € 3.5 / 100km! When invoicing is made per. consumed kWh, Ionity top-ups alone would represent € 19.98 at this point of the journey (with subscription), i.e. almost € 30 in total with full charge on a domestic socket.

What is the Supertest?

Lovers of numbers and allergic to official data sheets, Supertesten, Automobile-Propres new test format, is made for you, and collects data collected during a test under real conditions and according to a transparent and accurate protocol. We will add them on Wednesday after the publication of the second part dedicated to the Hyundai Ioniq 5 HTRAC to our summary article makes it possible to compare the noted values ​​of the tested models, which will make the whole value of the section.
