What EV Charger Do You Need for a 2023 Mercedes-Benz EQS 580?
Wiring a 60-amp breaker and hardwiring your charger is mandatory for this car. You need a 48-amp Level 2 setup to hit the maximum onboard charging rate of 11.5 kilowatts. Plugging into a standard wall outlet will not cut it. Hire an electrician.
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 10.4 hours |
| Range added per hour (Level 2) | about 27 miles |
| Full charge on a 120 V outlet | about 83 hours |
| Range added per hour (120 V) | about 3.4 miles |
| EPA rated range | 285 miles |
| Energy for a full charge | about 119.9 kWh at the wall |
Why 48 amps and not more
The car accepts up to 48 amps through its onboard charger. Pushing more amperage from a 50-amp or 60-amp EVSE will not speed up the charge because the vehicle limits the intake. Buying a larger unit wastes money. You get 27 miles of range per hour of charging at the 48-amp ceiling. A full battery takes 10.4 hours from zero.
What the install involves
A 48-amp charger must be hardwired directly to the circuit breaker. No household receptacle handles that continuous load safely. Your electrician must run heavy-gauge wire to a 60-amp breaker in your main panel. Do not attempt DIY wiring for this amperage. Safety inspections are standard practice.

Common questions
- What plug does the car use?
- The vehicle uses a J1772 connector for Level 2 charging. Every non-Tesla EV sold in North America through 2024 uses this standard.
- Can I use Level 1 standard outlets?
- You can plug into a standard household outlet in a pinch. It takes 83 hours for a full charge and adds only 3.4 miles of range per hour.
- Why does the EPA charge time differ?
- The EPA rated charge time is 12.8 hours, yielding 22 miles per hour. The EPA test does not always run at the car's peak AC rate.
- Which chargers fit this vehicle?
- Units like the Emporia Level 2 EV Charger 48A and the Wallbox Pulsar Plus 48A match the car's maximum input. Hardwire them to get the full 48 amps.
