What EV Charger Do You Need for a 2025 Mercedes-Benz EQE 500?
You will need a licensed electrician to run a dedicated 50 amp breaker and wire a NEMA 14-50 outlet in your garage. This hardware setup matches the 40 amp maximum onboard charger of your Mercedes-Benz EQE 500. Plugging in overnight restores 24 miles of range every hour. A full recharge from empty takes 11.1 hours on Level 2 equipment.

| 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 11.1 hours |
| Range added per hour (Level 2) | about 24 miles |
| Full charge on a 120 V outlet | about 74 hours |
| Range added per hour (120 V) | about 3.6 miles |
| EPA rated range | 266 miles |
| Energy for a full charge | about 106.4 kWh at the wall |
Why 40 amps and not more
Your car draws 40 amps because that is the limit of its onboard AC charging hardware. Buying a larger 48 amp or 80 amp supply wastes money because the vehicle cannot draw the extra current. Electricity flows into the 106.4 kWh battery at a maximum rate of 9.6 kW. Extra capacity at the wall provides zero speed benefit for this specific model. Stick to the 40 amp ceiling for efficient power delivery.
What the install involves
A 50 amp circuit breaker is mandatory for safe operation under continuous load rules. The wiring must be sized properly to handle the current without overheating over long runs. Hardwiring eliminates potential points of failure found in standard plug connections, though a NEMA 14-50 outlet works fine if installed correctly. Hire a professional electrician to pull permits and verify your panel can handle the load.

Common questions
- Can I use a standard wall outlet?
- Yes, but Level 1 charging on a standard household outlet is extremely slow. It yields only 3.6 miles of range per hour and takes 74 hours to fill the battery.
- What charging cable does the car use?
- The vehicle uses a J1772 connector. Many 2025 models feature a NACS port alongside an included adapter, so verify your physical port before ordering.
- Why does the EPA charge time differ?
- The EPA estimates a full charge takes 11.5 hours at 23 miles of range per hour. Real world results hit 11.1 hours because testing conditions vary.
- What products fit this vehicle?
- The Grizzl-E Classic 40A, Grizzl-E Mini Portable, and ChargePoint Home Flex NEMA 14-50 all supply the exact amperage your car accepts.
