What EV Charger Do You Need for a 2024 Mercedes-Benz EQS 580?
Forty-eight amps is the magic number for your charging setup. You need a Level 2 home station capable of delivering this exact current to fill the 120.4 kWh battery. Plugging in overnight gets you 33 miles of range per hour.
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 33 miles |
| Full charge on a 120 V outlet | about 84 hours |
| Range added per hour (120 V) | about 4.1 miles |
| EPA rated range | 345 miles |
| Energy for a full charge | about 120.4 kWh at the wall |
Why 48 amps and not more
Your car accepts a maximum of 48 amps through its onboard charger. Pushing more current from a larger unit does not speed up the charge because the vehicle limits the intake. Buying a 50 amp charger like the ChargePoint Home Flex means scaling the internal dipswitches down to 48 amps to match the car. Level 1 charging is painfully slow at 4.1 miles per hour and takes 84 hours for a full tank. Stick with Level 2.
What the install involves
You need a dedicated 60 amp breaker to feed the circuit safely. Hardwiring is mandatory because no household receptacle handles 48 amps continuously without melting. Call an electrician to run THHN copper wire from your panel to the garage wall. Let them mount the Emporia or Wallbox unit directly to the studs.
Chargers that match this car

Common questions
- Do I need an electrician for this install?
- Yes. Running a 60 amp circuit requires pulling permits and working inside your main electrical panel.
- What plug does this car use?
- Your car uses a J1772 connector for Level 2 AC home charging. Every non-Tesla EV sold in North America through 2024 uses this standard.
- Why does the EPA charge time differ from the max rate?
- The EPA test runs at 11.5 hours instead of 10.5 hours because federal test procedures account for efficiency losses during the cycle. Real world charging at the full 48 amp rate hits the 10.5 hour mark.
- Can I use a regular wall outlet?
- No. Standard household outlets deliver Level 1 power at 120 volts and take 84 hours to fill the battery.
Other vehicles
Charging times derived from EPA data for the 2024 Mercedes-Benz EQS 580 (covering 2 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.
