Just got a Kona EV, home charging question

Why not get

Why not get an EVSE for your 14-30 outlet? They are under $350 and they charge at about 6.0 kwh speed.

With the adapter you double your charging speed.. with a 26 amp EVSE, you charge 5 times faster..

 

Yes that would work. It will allow you to use your level one charger on 240 volts making it a 12 amp level 2 charger. Note that you would still charge at 12 amps as that is the max for the charger that comes with the car but at 240 volts . It will charge twice as fast as 120 volt. That would be 30 hrs for 0-100 percent. But usually people are charging between 20-80 % and that would take about 18 hours.

Its also possible to make your own adapter if your comfortable with electrical wiring. I made one and had no issues charging at 240 volt. Here's a link to the site that makes the doubler and also has a lot of diy info under resources https://evdoctor4earth1.weebly.com/resources.html

 

Is your garage plug 3 o 4 prong receptacle? If its a 4 prong 14-30 NEMA receptacle you can get EVSE that supports up to 24 amps at 240 volts or roughly 5.7 Kw/hr charge rate. Or you could look into getting a 14-50 receptacle installed and getting an EVSE that can supply the full 32 amps or 7.6 Kw/hr that the Kona's on board charger supports.

 

Here's a link on various types of adapters for Level 1 and level 2. https://www.insideevsforum.com/community/index.php?threads/rv-adapter.6247/page-5#post-88279

 

That's a Nema 14-50 outlet. it can handle either 40 or 50 amps depending on the circuit breaker and wiring, It will allow a 32 amp level 2 charger.

The adapter you mentioned will work it. It just eliminates the neutral prong as its not used for a level 2 charger but it is a Nema 14-50 plug missing one prong

 

I made one of these adapters and it did work. My Hyundai charger is model 91670-K4020. The link I listed for the manufactures website does list the Kona for 2 other model #. My under standing is that Hyundai uses the same charger in Europe (230 volt) and North America (120 volt) Below is the list from the website.

Couple of Questions:

- what breaker is hooked up to this outlet? If it’s a 40amp then 32ams is max you will draw(80% is the rule in regards to a breaker)

- do you own or rent? If you renting make sure you have the OK of landlord before making ANY changes to electrical

look at my setup in one on the posts I actually made a mistake....in my house I have a good setup 50amp(80% is 40amps) but I purchased a 32 amps Level 2 charger....honestly should have went with a 40amp for simple reason as to FutureProof myself. I am also running an extension to my charger so it’s actually 50ft...

 

WOW! That's a 20 amp circuit breaker with a 50 amp outlet. I would verify the wire size or have an electrician check it out . For a 30 amp dryer it should be at least 10 gauge. For a 40 amp outlet it wold be 8 gauge and for a 50 amp outlet it would be 6 gauge. Hopefully some one just replaced the circuit breaker with a smaller one. That's ok. But if they put a 50 amp outlet on a 20 amp circuit that a fire hazard!

 

Yes and No...

when you upgrade the breaker you need to make sure the wire that’s providing the power can handle it. I suggest what they call

- 8/3 for 40amp Breaker(32amp capacity)
- 6/3 for 50amp Breaker(40amp capacity)


I have a NEMA 14/50 plug(can handle 50amps basically) along with a 50amp breaker all running thru a 6/3 wire.

But I messed up on the charger should have paid the extra 60-80$ and gotten a 40amp one. Even thou now is am getting Constant 32amps no more or less which is nice (7.62kWh on 32amps charger/40amps breaker vs 9.6kWh on a 40amps charger/50amps breaker).


So honestly all depends on your skills as an electrician and how hard it is to change your breaker AND wiring. If your plug and power panel is say 10-15ft away from each other in a garage.... I would go for it.

But I you got to fish a new line they half the house....you might think about having an electrician look at it.

I also had to deal with having aluminium wires in my house. So don’t let yourself be scared away by a little bit of work

 

I would check that again, a 100 amp breaker should not be feeding a receptacle that is max rated to 50 amps.

 

I have used that EVSE on my Kona for 10-30 outlet. The one for 14-30 will work just fine with the Kona too. I later changed my outlet to 14-50 to go with a 32 amp EVSE but I did use the 26 amp on a 10-30 outlet for a little while.. Like I said, I got 6.0 kwh with the 26 amp EVSE. With the 32 amp, I now get 7.5 kwh charging speed on the input side.
Any EVSE with the J1772 plug will work with the Kona.

 

Double Check what you just read:

- it might be your panel is 100amps
- and your breaker is 20amps

It would be very unusual for that 14-50 dryer outlet to be protected by either a 20A or a 100A breaker. You're either misunderstanding the wiring, or you've got a really non-standard (and unsafe) situation there. Either way, it's probably a sign that you should get an electrician involved on this one. It's not rocket science, but it does require some basic knowledge of wiring, and with high-amperage 240V circuits, and big loads, the consequences are pretty serious.

If you want the simplest and cheapest solution, get (or make) a 14-50P to 5-15R adapter, and plug your Hyundai charger into the dryer receptacle. It'll only draw 12A (240V), and you'll get charging that is probably fast enough for your needs. At our place I added a 50A circuit, with a dedicated 14-50 receptacle, and bought a 40A charger. That gives us the ability to charge at 7.2kw speeds (max capability for the Kona). While it's occasionally nice to have, if I knew that the supplied charger could be run at 220V, I probably would have saved my $500, and just gotten by with the 2.7kw charge speed. The only time that would be a problem is if we did two long trips on consecutive days, and needed to add more than 50% charge overnight.

 

Your 100 amp is perhaps the main for the panel, likely near the top.

The breaker for that 14-50 outlet is likely a double-pole 50A, i.e. you
still haven't found it yet. It's perfect for a level 2 EVSE that comes with
a 14-50 plug; they are quite common. Question is then if the cables
can reach your car.
