In North America, the fastest common home EV chargers deliver 48 A at 240 V, which is about 11.5 kW, on a hard-wired 60 A circuit. A few go to 80 A for vehicles that accept it. In Europe, home wallboxes go up to 22 kW on a three-phase supply. In practice, the car’s on-board charger sets the limit: many accept 7.2–11.5 kW, so a bigger charger will not make them charge faster.
Home Charger Power Levels
| Charger current | Circuit | Power at 240 V | Range per hour (approx.) |
|---|---|---|---|
| 32 A | 40 A | 7.7 kW | 25 miles |
| 40 A | 50 A | 9.6 kW | 30 miles |
| 48 A | 60 A, hard-wired | 11.5 kW | 35 miles |
The circuit must be rated at 125% of the charger’s current, because EV charging is a continuous load. See what size breaker for an EV charger.
How to Get the Fastest Charging at Home
- Check your car’s maximum AC charging rate in the owner’s manual.
- Choose a charger at or slightly above that rate.
- Confirm your panel can supply the circuit; an electrician can run a load calculation.
- Use load management if the panel is tight, so charging slows instead of tripping the main breaker.
Home charging is AC. DC fast charging, which can be far faster, needs a large three-phase commercial supply and is not practical at most homes; see Level 1 vs Level 2 vs DC fast charging.
High-Power Home Chargers From EVDANCE
The EVDANCE EV-ACT5006T 48A Level 2 wall charger delivers up to 48 A hard-wired, or 40 A on a NEMA 14-50P plug. For three-phase homes, the EVDANCE EV-ACT3204E 22 kW wallbox delivers up to 22 kW.
Frequently Asked Questions
Is a 48 A charger worth it over 40 A?
Only if your car accepts more than 9.6 kW AC and your panel can supply a 60 A circuit.
Can I install a DC fast charger at home?
It is technically possible but rarely practical because of the power supply and cost.
What is the fastest Level 2 charging speed?
Up to about 19.2 kW at 80 A for a few vehicles; most cars accept far less.
