What EV Charger Do You Need for a 2025 Kia EV9?
Forty-eight amps. That is the exact draw your Kia EV9 accepts at home. You need a 48 amp Level 2 setup to match the onboard charger. A standard plug will not cut it.
The numbers
| Maximum AC charging rate | 10.9 kW (48 A) |
|---|---|
| Charger size to buy | 48 A |
| Circuit breaker required | 60 A |
| Outlet / connection | hardwired (a 48 A EVSE must be hardwired -- no household receptacle is rated for it) |
| Charge port | J1772 |
| Full charge on Level 2 | about 10.6 hours |
| Range added per hour (Level 2) | about 29 miles |
| Full charge on a 120 V outlet | about 80 hours |
| Range added per hour (120 V) | about 3.8 miles |
| EPA rated range | 304 miles |
| Energy for a full charge | about 115.5 kWh at the wall |
Why 48 amps and not more
The battery holds 115.5 kWh of energy. Pumping power in at 10.9 kW fills that massive pack from empty in 10.6 hours. If you step down to a smaller unit, charging takes longer. Buying a 60 amp breaker feeds the 48 amp load safely under continuous duty rules. Pushing past this limit does nothing because the car caps its intake right at 48 amps.
What the install involves
A 48 amp load requires hardwiring because no household receptacle handles that continuous draw. Have a licensed electrician pull a heavy copper circuit and land it on a 60 amp breaker. Ask them to verify your main panel has spare capacity before they start. The hardware mounts directly to the wall and wires straight into a junction box.

Common questions
- Can I plug this car into a normal wall outlet?
- Yes, but Level 1 charging takes 80 hours to fill the battery from empty. You will only recover 3.8 miles of range per hour. Hardwired Level 2 is far faster.
- Why does the EPA charge time say 15.2 hours?
- The EPA test protocol does not always run at the car's peak alternating current rate. Real world charging at the maximum 48 amps takes 10.6 hours.
- Do I need a special connector for this model?
- This vehicle uses a J1772 connector. Many 2025+ models ship with a NACS port but include an adapter in the trunk. Check your specific port before buying hardware.
- What breaker size do I need for the charger?
- You need a dedicated 60 amp breaker. National electrical code requires a 25 percent safety margin above the continuous 48 amp load.
Other vehicles
Charging times derived from EPA data for the 2025 Kia EV9 (covering 3 EPA trim listings). Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
