What EV Charger Do You Need for a 2020 Nissan Leaf SV SL?
Twenty-eight amps is the magic number for this Leaf. You need a 40 amp breaker to feed it properly. Charging takes 10.5 hours from empty to full at Level 2 speed.
The numbers
| Maximum AC charging rate | 6.6 kW (28 A) |
|---|---|
| Charger size to buy | 32 A |
| Circuit breaker required | 40 A |
| Outlet / connection | NEMA 14-50 outlet on a 40 A breaker, or hardwired |
| Charge port | J1772 |
| Full charge on Level 2 | about 10.5 hours |
| Range added per hour (Level 2) | about 20 miles |
| Full charge on a 120 V outlet | about 48 hours |
| Range added per hour (120 V) | about 4.5 miles |
| EPA rated range | 215 miles |
| Energy for a full charge | about 69.4 kWh at the wall |
Why 32 amps and not more
Your car accepts a maximum of 28 amps on AC power. Buying a larger 40 amp or 50 amp charger will not speed up the process. The vehicle onboard hardware dictates the speed limit. Extra capacity at the wall sits idle. Stick to the 32 amp recommended equipment to hit the peak rate cleanly.
What the install involves
Code requires a 40 amp breaker for this continuous load. You can plug into a NEMA 14-50 outlet or hardwire the unit directly to the wall. Hardwiring removes a point of failure and bypasses ground fault requirements in certain garage locations. Hire a licensed electrician for the panel work and wiring run. Safety depends on correct torque specs and wire gauge.

Common questions
- What plug does this car use?
- It uses a J1772 connector for standard Level 2 home charging. Every non-Tesla EV sold in North America through 2024 uses this exact plug format. You do not need an adapter for home units.
- How fast does Level 2 charging go?
- You get 20 miles of range for every hour plugged into a Level 2 source. A complete recharge takes 10.5 hours at the maximum onboard rate of 6.6 kilowatts.
- Can I use a standard wall outlet?
- Yes, but Level 1 charging on a standard household outlet takes 48 hours for a full tank. It only yields 4.5 miles of range per hour. You want a 240 volt setup for daily convenience.
- Why does the EPA estimate differ?
- The EPA rated charge time sits at 11.0 hours for a full session. Federal testing protocols include efficiency losses inherent in the conversion process rather than raw battery capacity math alone.
Other vehicles
Charging times derived from EPA data for the 2020 Nissan Leaf SV SL. Electrical requirements follow NEC 625.41, which sizes a circuit at 125% of a continuous load. Always have a licensed electrician verify your panel.
