You need to install a Level 2 charger (officially called EVSE, Electric Vehicle Supply Equipment) in your garage or on an outside wall near your driveway. It supplies 240V at increased amperage to charge the car faster than a normal wall socket can manage.

The Plug-in Hybrid Ioniq has a peak charging speed of 3.5 kW (14.6 amps at 240V), so an EVSE installed on a 20A breaker will charge your car at its fastest rate in about 2 hours and 15 minutes from empty. I would suggest getting at least a 32A EVSE on a 40A breaker to be future proof. Many big box hardware stores carry them these days, but you'll need a permit and an inspection for the install. Hiring a licensed electrician to do the work is the best way to ensure that it's all done safely and legally.

 

Thanks for the response, and for the good information. We are sadly renting an apartment and thus can't make such an upgrade. I did realize yesterday that we are getting mid-grade speed (4 hours to fill up) at many public places, and the slowest speed (8 hours) at a few others. Never having had the patience to sit for a full fillup, I didn't notice the two different speeds happening. Plus, I'm working form home so driving less anyway. Bottom line, once we get our own house, we need to install a system like you describe. When I originally wrote the post, I thought maybe some other charging cord would enable us to get the fastest speeds from public charging locations. I realize now it's not a matter of the charging cord, but of the charging source.

 

Well, if you have either a 240V wall outlet or two 120V outlets of opposite phases, it's possible to double the charging speed by using an adapter with the granny charger that comes with the car.

Caution! Doing so is of course entirely at your own risk, and might invalidate your warranty and insurance or even be illegal. So you'd better know what you're doing...

evdoctor.net sells various adapters for that purpose, or you can buy the parts separately at some other dealer and assemble an adapter yourself.

 

Thanks again. I'd be looking at some very difficult hiding of the charger cords if I were to attempt to do one, never mind two.

I'm probably mixing already-discussed-elsewhere topics, but why can't I get some sort of portable charger, charge it up here in my apartment, then plug it into the car? If a portable car charger is plausible, ideally one that you can charge up multiple ways (solar, regular AC), then what is the right one to get for the 2020 Hyundai Ioniq Plug-In Hybrid?

So, to clarify, you're suggesting a secondary battery to charge up in your apartment that also has an inverter that can produce 120V or 240V AC to charge your car. Technically, these portable batteries do exist:

Goal Zero Yeti Lithium 1500X Portable Power Station

However, if you look at the specs, this only has 1.5 kWH of capacity, which is roughly 1/6 the capacity of your PHEV battery. It also weighs an impressive 45 lbs and costs $2,000. So, not a practical solution, unfortunately.

Also, please do not under any circumstances try to make your own 240v charger circuit from two different phases. You are asking for pain. This can be accomplished by a licensed electrician (will likely need to be permitted as well, depending on your local code), but should not be attempted by anybody who is not thoroughly schooled in electrical engineering. You can ruin your car, start a fire, or even possibly electrocute yourself. It's also definitely illegal and if caught you could possibly face legal problems and likely an eviction from your apartment. It's just not worth it.

My suggestion would be to modify your shopping trips / outings / etc. to include charging stops. Often a little bit of planning, and maybe a slightly further walk to where you're going, can end up in being able to charge the car while you do other things, rather than just sit in the car waiting for it to charge. Also, consider the need to charge the battery up to 100%. Would a trip where you netted a 10-20% increase in your battery's SOC be worth it? Maybe so! Then maybe another, similar trip a day or so later? Think of it as charging as you go, rather than charging to 100%, running the battery down and then charging to 100% again. It's a more "EV" style of thinking, rather than an ICE fuel based way of thinking.

Good luck to you!
