What is the charging speed of an electric car?

The charging speed indicates how many kilometers of driving range a battery is recharged per hour.

The charging speed depends on:

1. The maximum charging capacity (in kW).
2. The energy consumption of the electric vehicle (in kWh/100km).

How is the charging speed calculated?

(Charging capacity in kW × 90% efficiency) / Consumption in kWh per 100 km

Example:

(2.3 kW x 90%) / 15 kWh per 100 km = 14 km/hour or 7.25 hours per 100 km (7.4 kW x 90%) / 15 kWh per 100 km = 44 km/hour or 2.25 hours per 100 km
