What EV Charger Do You Need for a 2022 Mercedes-Benz EQS 580?
Wiring a 60-amp circuit with a hardwired connection is the baseline requirement for your car. You need an electrician to run heavy gauge wire from the main panel to the garage. Plugging into a standard wall outlet will not cut it.
The numbers
| Maximum AC charging rate | 11.5 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 10.5 hours |
| Range added per hour (Level 2) | about 32 miles |
| Full charge on a 120 V outlet | about 84 hours |
| Range added per hour (120 V) | about 4.1 miles |
| EPA rated range | 340 miles |
| Energy for a full charge | about 120.8 kWh at the wall |
Why 48 amps and not more
Your car accepts a maximum of 48 amps of Level 2 charging current. Buying a larger charging unit makes zero sense because the onboard charger limits intake anyway. Feeding it a 48-amp supply refills the 120.8 kWh battery in 10.5 hours. You get 32 miles of range for every hour plugged in. The EPA test estimates a slower rate of 27 miles per hour because test cycles account for power conversion losses.
What the install involves
A 48-amp continuous load demands a 60-amp circuit breaker. No household receptacle handles this amperage safely, so hardwiring the unit is mandatory. Call a licensed electrician to pull the permit and inspect your service panel. Do not attempt DIY work unless you hold a license.
Chargers that match this car

Common questions
- Can I plug this car into a standard wall outlet?
- Yes, but charging takes 84 hours from empty. Level 1 speeds yield only 4.1 miles of range per hour.
- What connector does the car use?
- The vehicle uses a standard J1772 plug. Every non-Tesla EV sold in North America through 2024 uses this connector for AC Level 2 charging.
- Why does the EPA charge time differ from the max rate?
- The EPA rated charge time takes 12.5 hours at 27 miles per hour. Standard efficiency testing includes thermal management overhead and onboard conversion losses.
- Should I buy a 50-amp charger?
- The car maxes out at 48 amps. A larger unit will not speed up your charge time.
Other vehicles
Charging times derived from EPA data for the 2022 Mercedes-Benz EQS 580. Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
