What EV Charger Do You Need for a 2024 Kia EV9?
Wall chargers can deliver plenty of power, but your vehicle dictates what goes into the battery pack. The Kia EV9 accepts a maximum of 48 amps at 10.9 kilowatts for home Level 2 charging. You need a 48 amp EVSE to feed this vehicle at its top AC rate. Anything smaller leaves speed on the table.
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
Matching the 48 amp onboard charger means you refill the 115.5 kWh battery in 10.6 hours. If you plug into a smaller 32 amp or 40 amp unit, charging takes longer because the vehicle cannot draw more power than its onboard hardware allows. Pushing past 48 amps makes no difference either. The car caps its AC intake at 48 amps. Buying a larger 60 amp or 80 amp charger gives you zero speed gains.
What the install involves
Feeding a 48 amp continuous load requires a 60 amp breaker and heavy gauge copper wiring. No standard wall outlet handles this current safely, so your electrician must hardwire the EVSE directly to the circuit. Have a professional check your panel for spare capacity before buying parts. If the main breaker is maxed out, you might need a load management system.

Common questions
- How fast does Level 2 charging restore range?
- You gain 29 miles of range for every hour plugged into a 48 amp Level 2 charger. The EPA testing yielded 31 miles per hour under specific conditions. Either way, an overnight session easily fills the battery from empty.
- Can I use a standard 120 volt household outlet?
- Level 1 charging works on a normal wall plug, but it delivers only 3.8 miles of range per hour. A full recharge from empty takes 80 hours using this method. Treat Level 1 as an emergency backup rather than a daily solution.
- What plug connector does this vehicle require?
- The Kia EV9 uses a J1772 connector for all AC Level 2 charging. Every non Tesla EV sold in North America through 2024 uses this standard port. You can use adapters for Tesla destination equipment if needed.
- How long does a full charge take at maximum speed?
- Plugging into a 48 amp Level 2 unit takes 10.6 hours to go from zero to full. The EPA rated charge time sits at 9.9 hours because standard government test cycles do not always run at the absolute peak AC rate.
Other vehicles
Charging times derived from EPA data for the 2024 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.
