What EV Charger Do You Need for a 2024 Mercedes-Benz EQE 350?
Forty amps is the target. Your car takes a maximum AC draw of 40 amps at 9.6 kilowatts. You need a Level 2 setup matching those specs to refill the 109.7 kilowatt-hour battery overnight. Plan on 11.4 hours for a zero to one hundred percent charge.
The numbers
| Maximum AC charging rate | 9.6 kW (40 A) |
|---|---|
| Charger size to buy | 40 A |
| Circuit breaker required | 50 A |
| Outlet / connection | NEMA 14-50 outlet |
| Charge port | J1772 |
| Full charge on Level 2 | about 11.4 hours |
| Range added per hour (Level 2) | about 27 miles |
| Full charge on a 120 V outlet | about 76 hours |
| Range added per hour (120 V) | about 4.0 miles |
| EPA rated range | 307 miles |
| Energy for a full charge | about 109.7 kWh at the wall |
Why 40 amps and not more
Buying a bigger 48 amp or 80 amp charger does nothing for this car. The onboard charger limits incoming power to 40 amps. Extra capacity at the wall sits idle. Stick with the recommended 40 amp EVSE. It pumps 27 miles of range into the pack every hour.
What the install involves
Wiring this setup demands a 50 amp breaker on a dedicated 240 volt circuit. The car plugs into a NEMA 14-50 outlet using a standard J1772 connector. Hardwiring works too and eliminates a physical plug point that can generate heat over time. Hire an electrician for the panel work and permit.

Common questions
- Can I use a standard wall outlet?
- Yes, but Level 1 charging on a standard 120 volt household plug is painfully slow. It takes 76 hours to refill the battery from empty at a rate of 4.0 miles of range per hour. Install a 240 volt Level 2 circuit.
- Why does the EPA charge time show 12.5 hours?
- The EPA test cycle includes conversion losses and charging inefficiencies inherent to the process. The raw math based on your onboard charger points to 11.4 hours. Real world conditions will land between those figures.
- Do I need an adapter for public stations?
- Your car uses the J1772 connector for standard Level 2 AC charging found across North America. No special adapters are required for public AC plugs. DC fast chargers use a different port entirely.
- What specific hardware should I buy?
- Units like the Grizzl-E Classic 40A or the ChargePoint Home Flex NEMA 14-50 match your car's maximum 40 amp limit. Both plug directly into the required outlet. They deliver the full speed your onboard charger can accept.
