Typical full-speed install
40A charger on a 50A circuit
Reaches this car's 9.6 kW ceiling. Whether your panel has room for that circuit depends on everything else already on it - that's the actual assessment.
Connector
CCS
CCS (Combined Charging System) is the most common connector on non-Tesla EVs for both home Level 2 charging and public DC fast charging.
On the EQS Sedan AMG specifically, that connector carries up to 9.6 kW at home on Level 2 and up to 200 kW on public DC fast hardware.
Charging speed by circuit size
The Mercedes-Benz EQS Sedan's onboard charger can't use more than 9.6 kW AC no matter how big the circuit - past 48A, a bigger charger buys you nothing on this car.
| Charger setting | This car actually draws | Range added / hour | 8-hr overnight |
|---|---|---|---|
| 16A | 3.8 kW | ~10 mi | ~80 mi |
| 24A | 5.8 kW | ~15 mi | ~120 mi |
| 32A | 7.7 kW | ~21 mi | ~168 mi |
| 40A | 9.6 kW | ~26 mi | ~208 mi |
| 48A | 9.6 kWcapped by car | ~26 mi | ~208 mi |
Overnight, at full onboard speed
208 mi / 8 hrs
260 mi across a 10-hour window, at 9.6 kW.
Approximate cost to fill from empty
$15.34
Assumes $0.13/kWh (a national-average estimate, not your local rate) × 118 kWh - about $0.049/mile.
Mercedes-Benz EQS Sedan charging questions
How long does it take to charge a 2024–2026 Mercedes-Benz EQS Sedan AMG on a Level 2 charger?
About 12.3 hours from empty to full at its 9.6 kW onboard-charger ceiling (118 kWh battery ÷ 9.6 kW).
Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a Mercedes-Benz EQS Sedan draw on Level 2?
At its full 9.6 kW rate, the Mercedes-Benz EQS Sedan draws about 40A at 240V (kW × 1000 ÷ 240 = amps).
Can a Mercedes-Benz EQS Sedan use a 48-amp charger?
Not to any real benefit. The Mercedes-Benz EQS Sedan's onboard charger tops out at 9.6 kW (~40A) - a 48A charger doesn't charge it any faster than one already sized to 40A.
How much range does a Mercedes-Benz EQS Sedan add per hour on a Level 2 charger?
About 26 miles of range per hour at its 9.6 kW ceiling (9.6 kW × 2.67 mi/kWh efficiency).
How much range does an 8-hour overnight charge add to a Mercedes-Benz EQS Sedan?
Roughly 208 miles from an 8-hour overnight charge (26 mi/hr × 8 hours), or about 260 miles across a 10-hour window.
What's the DC fast charging ceiling for a Mercedes-Benz EQS Sedan?
Up to 200 kW on a public DC fast charger - well above its 9.6 kW Level 2 (home) ceiling, though DC fast rates taper as the battery fills.
