Hyundai Ioniq 28kWh - thread 2.0

Yeah, I'm noticing exactly the same issue recently, like you thought it was the key fob battery but havent gotten round to changing it yet! I have had the battery saver warning on once or twice though so could be the 12V alright (Im in a 171 with the original battery!) Have a decent trickle charger at home so Ill hook it up when I get a chance (just for reference! Im sure I've had the value from the original at this stage anyway!).

Thanks for the info from other posters!!

Hi fluffykre

I found this super post after a trawl and hoping you any other 28kWh Ioniq owners with solar can assist?

I have an Ioniq 28kWh and Zappi v1 and I had a small solar array 2.4 installed recently.

Ideally I would like to only use 100% surplus into the Ioniq.

My understanding of the posts and youtube (and my own tests) is that it is only possible to get 100% surplus into EV at 1.4kWh from Solar.

When I reduce the MGL to say 50% in ECO+ and set Current Charge in Ioniq to Minimum - the Ioniq will charge at 700w from Solar BUT still imports the other 700w from the grid in order to meet the 1.4kWh EV Charging Standard. Which is very useful for charging on cloudy days.

So there is no way to get 100% surplus only into the Ioniq at less than 1.4kWh. (Please tell me this statement is wrong 😀)

Best reading I've ever seen was 210 to 215 kms on gom at 100 percent charge.

I have however got the equivalent of 235 kms range in terms of kms travelled per percent (ie 2.3 kms travelled for every percent of battery used)

What's the point of charging during the day with 60% solar? The saving would be tiny compared to charging at less than half price night rate.

@denismc - fair enough - get more PV though 😁

End of production of a model doesnt stop the after sales support when the manufacturer stays in business.

Even when a model is being replaced - you often find that the new model is a totally new model - new engines, platform etc.

So the manufacturers have the ability to maintain after sales support for the models they are discontinuing.

I wonder will there be some kind of Ioniq 3 replacement albeit a crossover.

Hi Zamboni just seeing your message now. I have had my zappi charger installed for a few months and I am able to get the car to take as low as 0.5kW.

This is my setup:

Zappi is priority 01.

Car is set to minimum on both options on EV settings (one of them controls the lowering on the zappi charge)

Zappi - Charging mode Eco+

Set the minimum use (the scale 1 to 100%) to 1%

This allows the car to keep charging when clouds move over the panels. When it gets later in the day and there's only 0.1kW excess then 0.4kW comes from the grid.

Eddi is set to Priority 2

When the car is used during the day the excess can be dumping into the hot water cylinder so if I need to pop out for an hour i'm not sending that energy to the grid. Same in the evening when I see excess starting to move down to 0.1kW I will stop charging and let the eddi take the excess.

I would love a battery (commercial or DIY) and more panels however this is quite cost affective with a 24 hour meter. Over the past 2 months I have pushed around 200kWh into the car each month, At around 90% from solar. I am presenting running 75% on day time units so at the end of the year I will run the numbers to see if sticking with the 24 hour makes sense.

200kWh x 8km/kWh = 1,600km x 0.9 = 1,440 km a month in free travel purely from solar. My thoughts are solar all the way over night charging if you can charge as low as 500 watts.

This is what makes the ioniq 28 a perfect compliment to someone who has solar without a home storage battery. Other options would be a Kia eniro however all the kia eniro in ireland came with 3phase which means this trick wont work, maybe a UK import single phase kia eniro.

Zamboni let us know how you get on when you teak the setting like above! Based on your array size, night rate may make the most sense. If you could upgrade the array to 4 or 6kW it would be easier to have more time solar above the 500 watt level

Class, @Neleven - long may your Ioniq 28 last!

Am planning to keep it indefinitely so long may it last indeed!

I would guesstimate around 10% loss based on usage: for example, drove 198kms yesterday at 11.8 efficiency with 28kms left. At full capacity, if my understanding is correct, 10.0 efficiency would give 280 kms range, 14.0 efficiency would get 200 kms range so 12.0 efficiency would deliver 240: so 220 give or take for 11.8 suggests about 10% loss of range. Of course, I have no idea whether the losses will accelerate as it gets older or whether at 400000 it will have lost 20%, but the truth is, even if it’s worse the car serves me very well: 50kms each way commute with capacity for further runs to all the kids’ activities after. 90% + charge at home on night rate. Do one or two trips annually of around 300kms, mostly motorway, but I just take my time and anticipate delays at chargers (though mostly I’ve been lucky).

@Neleven - the car will be able to do a 100km commute in winter for many years to come, no doubt about it. And with a long commute like that in a relatively cheap EV like the Ioniq 28, you will save yourself a fortune each year in fuel. And save the planet from tonnes of fumes.

@unkel and @ELM327 above, couldn’t agree more: the ioniq was and is ideal - probably the best value for money EV there’s been considering range, charging speed, comfort and more. That’s why I’m going to keep it. I did consider changing a year ago but not much that would be an upgrade would have been worth the money and availability wasn’t good (it’s even worse now).
