Hello,

It seems the HP for the RWD 72.6 KWh battery is incorrect, you have it listed at 292 HP, but it should probably be around 215 HP instead.
I like the chart and pictures, they are very informative.

Thanks,

Joe

 

You are right I will correct it. Thank you.
It is corrected.

 

Minor point, but shouldn't the 1st pic showing the 58Kw battery just have one motor at the rear?

I'd also assumed that whatever overall power figure each car had was dependant on the power o/p rating of each motor.
So I'd assumed that although the NA cars would have slightly greater range with the bigger battery, that the actual power o/p of each would be the same.
So do the NA car motors have a greater power o/p, or is it in some way related to the larger battery?

Motors and their controllers are typically limited by the current through them, so with a few extra cells in the pack you get more voltage at whatever the peak current is, and therefore more power.

Torque however is typically a function of current, not voltage, so you won't necessarily have better off the line acceleration. Voltage pushes current flow though, so where you are most likely to see that extra power is at the top end where there is more 'push' to keep the current flowing as the motor's back EMF (electrical counter pressure, a function of speed) is greater. Basically more get up and go when you tromp it at highway speed.

 

In case of damage to the battery pack eg heavy item hit on the road, does anyone know the price of a battery pack replacement? Quote from Hyundai, from dealership or from insurance company?

 

I guess around 8000 Euro. Very important is that your insurance covers a battery damage. Not all insurances does that. On our Renault Zoe, we had to take the Renault insurance to be covered for a battery failure or accident.

 

IONIQ 5 - E-GMP - all the BATTERY PACKS
I wanted to give you a complete overview of the different IONIQ 5 Battery configurations.
I made a Battery data table and pictures how the Battery Pack is assembled

Thank you for this very interesting information. I'm very surprised that there are two versions of the >70 KWH batteries. It seems like it just adds to the manufacturing complexity. Care to surmise why Hyundai is making two >70 kWh batteries?

 

The acceleration in Europe is more important than the range. They took 2 battery cell packs out from 32 to 30 to reduce the weight in favor of acceleration with 7% less range. The European and Oceanic top version with 225kw accelerates in 5.2 sec from 0-100km/h. In North America the range is more important and they use a battery with 32 battery cell packs, which is heavier, but to compensate the loss of acceleration they get in the top version 239kw.

 

i thought the us only gets the 77.4 kwh version, not the 58.2 one. is that right? or did i miss that information?

 

No the US we also get 58.2 KW like it is the case for Canada too. See Canadian link for per-ordering.

 

Important battery NEWS
https://www.rimac-automobili.com/
Croatian firm Rimac Automobile is building its own electric sports car. In addition to this activity, it also builds battery packs for other brands such as Aston Martin, Koenigsegg and other German manufacturers. According to Mati Rimac CEO and founder, it is possible to build a battery with a high range or a battery that can deliver a high energy. The ideal battery is one that can deliver a high range and a high energy. He could build such a battery. That is why many brands pour money into the Rimac company. Hyundai Motor Group has invested 90 million Euros in Rimac with 3 secret projects. 80 million euros comes from Kia, which is why they can build the first fast GT before the Ioniq 5 N comes out. That explains why an EV6 GT has already been proposed and not yet an IONIQ 5 N.

 

Just sensible of not releasing another GT at the same time as the sister brand. I think the ioniq 5 current positioning as a good value but still tech packed family EV is superb so no need for a spiced up version yet. Most of the competion has 500 hp versions, they would be entering a segment that is crowded atm. Hyundai also has the ioniq 6 coming in 2022 for buyers who want more speed. An N version will hopefully come but I would not be surprised if they launch ioniq 6 first. A new top version is always a nice moment to get new reviews from all those car reporters and vlogs, and prop up attention again.
Kia has a small SUV EV coming next year so the line up will be pretty complete, only a small well priced EV is missing:

• KIA EV4/5: small B segment SUV priced as ID 3
• EV6 / Ioniq 5: C/D segment crossovers (weird that for both cars they eschewed true SUV styling, I like that, but a lot of buyers will prefer classic SUV enyaq, IX, Q4 styling...
• Ioniq 6: looks like a very sporty hatchback, will probably be positioned above ioniq 5 in power and tech, so look out for that one
• ioniq 7: full size SUV
• Genesis 80: full size sedan

Not a bad line up? Compared with the VW group who released 3 times the same car
Smaller and cheaper will come (original Ioniq 2.0), but it makes sense to serve the upper part of market first as long as production is limited.... I suspect regularl cars will also not be sold under the ioniq brand after the starts this has taken - keep it exclusive - ....

 

For the 58.2 and the 72.6 versions you list two 'working voltages': one for the RWD and another for the AWD. What do you mean by 'working voltage'?
The nominal voltage for the 58.2kWh battery is 523V for both the RWD and AWD as both are using same battery. Similarly the nominal voltage for the 72.6kWh battery is 653V irrelevant to the number of motors.

From info I have gathered:
The batteries for the Ioniq 5 are sourced from SK Innovation and the individual cells are NCM811 with nominal voltage of 3.63V

72.6kWh battery:
Arrangement of 180s2p (180 groups of cells in series, each group contains 2 cells in parallel, total number of cells: 360).
Battery nominal voltage: 3.63x180=653V
Battery (and module and group) capacity: 72600/653=111.2Ah. Cell capacity 55.6Ah
What you are referring as 'packs' are modules, there are 30 of them, each contains 6 groups in series (12 cells total). The term 'pack' may indicate that this is the smallest item in the battery serviceable (replaceable) by Hyundai.

58.2kWh battery:
Arrangement of 144s2p, 24 modules of 6 groups.

77.5kWh battery:
Arrangement of 192s2p, 32 modules of 6 groups.

 

Thank you for this info, I modified my table and added other data. The data that I found on Hyundai Italy was called Working voltage, but I modified and adjusted it in nominal voltage, because your calculations are correct. Please check if it is OK now.

 

Anyone have an idea why the LR US version has 32 modules and the non-US version has 30 modules?

 

see my post

 

Are all Ioniq 5 (Europe, US etc) using the SK batteries (IE no LG battery) ?

 

US uses LG, rest of the world SKI, if I remember correctly

 

 

Jaz, I hope you are correct. I have already had 2 cars with flaming LG batteries. I don't need another one.
I don't think they have built even one car for export to the US. (But I hope I am wrong.) I understand the battery plant being built to support I5 manufacturing in the US is by SKI.

 

As most of you know, the US reservation site was shut down a few weeks ago. I don't remember what battery options it had. I was only interested in the 77.4 kWh. Sorry I can't help.

 

I just went back to the Ioniq 5 web site and they now have a configuration link. It lists no options for the battery. Screen shot is for the Limited, but the SE and SEL have the same options.

 

Regardless we can all agree that Hyundai is being extremely opaqe with the U.S. configuration from just about every perspective. They have to know by now what they plan to manufacture. The lead time for parts ordering, distribution, warehousing, etc. is quite long. If cars are to be out before the end of the year these decisions have already been made.

I don’t think Hyundai cares about folks who might be extra enthusiastic about their cars and that is their loss.

 

Agree CharleyPick. We really have no idea what will happen in the US. On today's webcast, the presenter said they started doing AWD for the US in August and will do RWD in Spetember. Not sure how much weight to put on his statements. I hope he is correct.

 

I hope this isn't so. My main consideration is range--basically how often do I have to stop when driving from San Jose to LA (and back). The Ioniq 5 has a bad enough range at high speed as it is. the AWD is even worse and is a non-starter for me. If I'm not getting a car until December, I may have to look elsewhere,.

 

Just copied this from the Ioniq 5 US web site. The only options shown for the 3 models are (I selected Limited), RWD or AWD, Exterior Color and Interior.

This is from the trim section. The Limited shows the 20" wheels only on the all wheel drive.

 

I think people are misinterpreting what the preorder/reservation system for the US at least was meant to be. I think it was mostly so they could gauge interest in the vehicle overall and relative interest between different coarse configurations. They aren't really real orders, and if memory serves they were fairly explicit way back that the configuration and options (or lack thereof) were not final. Likewise, the US was always planned to get release well after Europe, so their caginess w.r.t. pricing and final details makes some sense (particularly with supply chain issues causing further delays, and the company probably keeping a close eye on legal developments in the US)

 

This is what ABRP thinks of it:

So you only lose about 20min and 25.70$ - meaning you're only about 5% slower due to charging.
This is with the IONIQ 5 RWD US version (77kWh) and indeed mostly on the I-5.
The speed limit is set to 120km/h or 75mph.
Seems like a decent and very attainable journey

And you start with 90% SOC instead of 100%.

 

 

 

I only care if the battery is LFP which is much safer than NCA

 

?

 

Jaz, thanks for data. This will work great. We only drive a little faster in Arizona - the speed limit is 75 and you have to do about 80 mph (130km/h) to go with the traffic flow. The charging rate is the main reason I started to look at the Ioniq5. Now I have a lot of other things I like.

 

@Jaz Awesome charts and stuff. How did you come by this information about the cell arrangement, number of modules, nominal voltage, etc?
With the extra two modules, how much more does a 32 module car weigh than a 30 module car?
