What EV Charger Do You Need for a 2025 Hyundai Ioniq 5 Robo taxi?
A full charge takes 7.3 hours at maximum Level 2 speed, which easily fits inside a standard overnight window. You need a 48 amp EVSE to hit that speed. Level 1 charging takes 55 hours and is only useful for emergencies.

| Charge port | J1772 |
| Full charge on Level 2 | about 7.3 hours |
| Range added per hour (Level 2) | about 23 miles |
| Full charge on a 120 V outlet | about 55 hours |

| Energy for a full charge | about 79.8 kWh at the wall |
Why 48 amps and not more
The car accepts a maximum of 48 amps. Buying a charger that delivers more amps will not speed up your charging time because the onboard charger caps the intake at 10.9 kW. A 48 amp unit replenishes 23 miles of range every hour. The EPA-rated charge time is 10.3 hours because the federal test cycle calculates the process differently and does not run at the car's peak AC rate the entire time. Match your equipment to the vehicle limit to avoid paying for capacity you cannot use.
What the install involves
You need a 60 amp breaker to supply a 48 amp continuous load. This setup requires hardwiring because no household receptacle is rated for a 48 amp draw. Hire a licensed electrician to run the heavy gauge wire from your electrical panel to the mounting location. Code requirements for EV supply equipment are strict, so professional installation keeps your house safe.

Common questions
- What connector does this car use?
- It uses a J1772 connection. This model year falls in the industry's NACS transition, and many vehicles ship with a NACS port while including a J1772 adapter. Confirm your car's port before buying.
- Can I use a standard wall outlet?
- Standard household outlets deliver Level 1 power at 3.0 miles of range per hour. Charging from empty takes 55 hours on that setup. You need a dedicated Level 2 circuit for daily driving.
- What happens if I buy a 50 amp charger?
- The car only draws 48 amps. Units like the ChargePoint Home Flex let you configure the output to match your car or panel limits. You will not get extra speed by going above 48 amps.
- Why does the EPA test show a 10.3 hour charge time?
- The EPA rating uses a standardized test protocol that differs from the car's peak AC rate. Your actual home charging time at maximum Level 2 speed is 7.3 hours.
Other vehicles
