Home charging for Hyundai and Kia EVs

What the cars actually accept

Hyundai’s own FAQ lists the Tesla Wall Connector as an 11 kW (48 amp) Level 2 charger that works with the 2025 Ioniq 5. Published figures for the Ioniq 5 AC rate sit near 11 kW. For the Ioniq 6, the Kia EV6 and the Kia EV9, third-party sources describe a similar limit of roughly 10.9 to 11 kW, though the EV6 has been listed at both 46 and 48 amps by retailers. Treat the Kia numbers as a starting point, since Kia’s own spec is not quoted here, and read the owner’s manual for your model year.

What this means for the circuit:

Charger setting	Breaker	Power at 240 V	Good for
48 A	60 A	11.5 kW	Matching the car’s limit
40 A	50 A	9.6 kW	Almost full speed, lighter on the panel
32 A	40 A	7.6 kW	Overnight charging for typical daily miles

Because the cars stop near 11 kW, a 100 amp circuit would buy nothing. Spend that money on a shorter wire run or a panel fix if needed.

The plug depends on the year

Hyundai says the 2025 Ioniq 5 is the first Hyundai with a native NACS port, and the Ioniq 5 N does not have one. Earlier Ioniq 5 years use J1772, and Hyundai states future new and redesigned models will carry only NACS. Kia is moving the same way, but check your car’s inlet rather than relying on the model name.

This changes what you buy.

• J1772 inlet: any J1772 wall charger works with no adapter.
• NACS inlet: a NACS charger, such as the Tesla Wall Connector, plugs in directly. A J1772 charger needs a certified adapter. Hyundai advises using only adapters with CSA or UL certification, and its warranty does not cover damage from non-Hyundai accessories.

The CCS adapter warning

Hyundai’s FAQ says the CCS adapter, the one that lets a NACS car use CCS fast chargers, cannot be used with AC Level 2 or Level 1 inlets, including home chargers. The page says it may cause vehicle damage the warranty will not cover. Do not use that adapter to connect a home J1772 unit. This matters because owners of a 2025 Ioniq 5 receive a CCS adapter and may assume it covers home charging. It does not.

Pick the circuit by your driving

A 40 amp breaker feeding a 32 amp charger delivers 7.6 kW. In an eight hour night that is about 60 kWh of energy. Most commuters use far less than that per day, so many owners do not need the full 48 amps. A lower circuit costs less and leaves room in the panel. The load calculation page shows how much room a 60 amp circuit takes compared with a 40 amp circuit.

If you share a garage or have a rental or condo, the plug you choose and the way you request approval matter. See the HOA and condo page.

Panel room and cost

As of October 2026, the typical SoCal range for a Level 2 install is $1,000 to $2,000, with the charger often extra. A 60 amp circuit usually costs more than a 40 amp circuit because of heavier wire and a larger breaker. Go to the cost page for drivers, and use time-of-use rates to cut the monthly bill.

Before you buy the charger

1. Find your inlet type (J1772 or NACS) on the car.
2. Read the owner’s manual for the maximum AC charging amps.
3. Decide how many amps you actually need overnight.
4. Pick a charger that matches the plug.
5. Have the electrician size the breaker and wire for the chosen amps.

Garages with more than one EV

Households often own a Hyundai or Kia next to a Tesla or a truck. The cars have different plugs and different limits, but the chargers can share a panel. Two 40 amp circuits cost less in copper and panel space than two 60 amp circuits, and a pair of cars charging overnight rarely needs the top rate. Ask the electrician about sharing one circuit with a controller. The page on load management covers it. A household with a truck can compare the Ford F-150 Lightning page. If you live in a condo, a charger in your own space still needs board approval, and the HOA page lists the steps.

Warranty and brand programs

Some dealers offer a free charger or a charging credit with a new car, and the offer changes often. A dealer-supplied charger still needs a licensed electrician and a permit. Ask what the program covers before you buy a second unit.
