What should you take from this guide
- Supply Fases
- Fases admitted by the car
- Maximum AC power
- Cost and scope of adaptation
The stages of the house and the car must match the chosen power.
Read the process from left to right. Each step must be resolved before turning the choice into a purchase.
Common Powers
In monophasic, 3.7 and 7.4 kW are usually compared. In triphasic, 11 and 22 kW are shown. They are nominal references: the actual configuration and limits may be lower.
Don't change the supply by a figure
It values daily energy, hours of parking, cost of adaptation and future vehicles. The electrical decision must be reviewed by an enabled installer.
When it's worth looking at the triphasic
The triphasic can be useful when it is already available, the vehicle supports AC load in three phases and there is a real need to recover a lot of energy in a few hours. If one of these elements is missing, the nominal power will not become a daily advantage.
Before you bring about changes in supply, compare the cost and the work with a well-managed monophasic alternative. Several hours at moderate power can cover the usual route.
Checklist before continuing
- Supply Fases
- Fases admitted by the car
- Maximum AC power
- Cost and scope of adaptation
| Nominal power | Electrical reference | Orientation use |
|---|---|---|
| 3.7 kW | 230 V · 16 A · monophasic | Moderate night recovery |
| 7.4 kW | 230 V · 32 A · monophasic | Faster domestic load if car and installation allow |
| 11 kW | 400 V · 16 A · triphasic | Vehicles with three-phase AC charger |
| 22 kW | 400 V · 32 A · triphasic | It only takes advantage of the whole compatible chain |
