EV charging power (potencia de carga del coche eléctrico)
The kilowatts at which an electric car takes in energy while charging. It is set by the weakest of three links: the charging point, the onboard charger of the car and the power available in the installation.
What charging power is
Charging power (potencia de carga) is the rate at which energy flows into your car’s battery, measured in kW. The higher it is, the shorter the charge. At home people talk about 3.7, 7.4, 11 or 22 kW; rapid charging starts at 50 kW.
What limits it
Your car charges at the power of its weakest link:
- The charging point: a 7.4 kW wallbox will not give more even if the car accepts 11.
- The car’s onboard charger: on AC the car converts the current itself; if it accepts 7.4 kW, a 22 kW point will not charge it faster.
- The installation: contracted power, cable size and protective devices. With 4.6 kW contracted you cannot charge at 7.4 kW without dynamic load balancing.
Guide table
| Power | Supply | Range added per hour |
|---|---|---|
| 2.3 kW | Single-phase, Schuko | 10 to 13 km |
| 3.7 kW | Single-phase, 16 A | about 20 km |
| 7.4 kW | Single-phase, 32 A | 40 to 45 km |
| 11 kW | Three-phase, 16 A | about 60 km |
| 22 kW | Three-phase, 32 A | about 120 km |
Rough figures based on consumption of about 17 kWh per 100 km.
Which power to choose
In most Seville flats and houses, with a single-phase supply, 7.4 kW is the standard: a 60 kWh battery goes from 20 to 80 % in about five hours, within the off-peak period. A plug-in hybrid is usually fine with 3.7 kW. With a three-phase supply and a car that accepts it, 11 kW. See home EV charger for a house in Seville, Spain.
