EQB 250+ FWD
Compact 3-row electric SUV. 11kW onboard charger — 48A Level 2 setup is the sweet spot. Here's what its onboard charger actually needs from your home's electrical panel.
Home (Level 2) charging facts
Pulled straight from the EQB 250+ FWD's onboard charger rating - not a generic EV number.

- Empty-to-full at max Level 2
- 6.0 hrs
- 66.5 kWh battery ÷ 11 kW
- Range added per hour
- ~38 mi/hr
- 11 kW × 3.46 mi/kWh efficiency
- DC fast charging

- Public chargers only - tapers as the battery fills
Typical full-speed install
48A charger on a 60A circuit
Reaches this car's 11 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 EQB 250+ FWD specifically, that connector carries up to 11 kW at home on Level 2 and up to 100 kW on public DC fast hardware.
Charging speed by circuit size
The Mercedes-Benz EQB's onboard charger can't use more than 11 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 | ~13 mi | ~104 mi |
| 24A | 5.8 kW | ~20 mi | ~160 mi |
| 32A | 7.7 kW | ~27 mi | ~216 mi |
| 40A | 9.6 kW | ~33 mi | ~264 mi |
| 48A | 11.0 kWcapped by car | ~38 mi | ~304 mi |
Overnight, at full onboard speed
304 mi / 8 hrs
380 mi across a 10-hour window, at 11 kW.
Approximate cost to fill from empty
$8.65
Assumes $0.13/kWh (a national-average estimate, not your local rate) × 66.5 kWh - about $0.038/mile.
Mercedes-Benz EQB charging questions
How long does it take to charge a 2022–2026 Mercedes-Benz EQB 250+ FWD on a Level 2 charger?
About 6.0 hours from empty to full at its 11 kW onboard-charger ceiling (66.5 kWh battery ÷ 11 kW).
Times scale with amperage - see the circuit-size table above for other settings.
What amperage does a Mercedes-Benz EQB draw on Level 2?
At its full 11 kW rate, the Mercedes-Benz EQB draws about 46A at 240V (kW × 1000 ÷ 240 = amps).
Can a Mercedes-Benz EQB use a 48-amp charger?
Not to any real benefit. The Mercedes-Benz EQB's onboard charger tops out at 11 kW (~46A) - a 48A charger doesn't charge it any faster than one already sized to 46A.
How much range does a Mercedes-Benz EQB add per hour on a Level 2 charger?
About 38 miles of range per hour at its 11 kW ceiling (11 kW × 3.46 mi/kWh efficiency).
How much range does an 8-hour overnight charge add to a Mercedes-Benz EQB?
Roughly 304 miles from an 8-hour overnight charge (38 mi/hr × 8 hours), or about 380 miles across a 10-hour window.
What's the DC fast charging ceiling for a Mercedes-Benz EQB?
Up to 100 kW on a public DC fast charger - well above its 11 kW Level 2 (home) ceiling, though DC fast rates taper as the battery fills.
