DC values (green) are theoretical minimums. The charge curve slows beyond 80% and varies by vehicle and temperature.

How to calculate charging time?

The basic formula is simple: time (h) = kWh to charge ÷ charger power (kW). The kWh to charge equals the battery capacity multiplied by the difference between target % and starting %. This simulator also applies a 90% efficiency factor to account for thermal losses during charging.

For DC fast charging, this calculation gives a minimum time: in practice, charging power decreases beyond 80% to protect the battery. For an accurate 10% to 80% calculation, the values are close to reality; beyond that, add 20 to 40% extra time.

Frequently asked questions — EV charging

How long does it take to charge an electric car?

Charging time depends on three factors: battery capacity (kWh), charger power (kW), and starting charge level. On a standard 2.3 kW domestic plug, expect a full night. On an 11 kW wallbox, 3 to 8 hours. On a DC fast charger (50–150 kW), 20 to 45 minutes from 10% to 80%.

How many kWh to charge an electric car?

The formula is straightforward: kWh charged = battery capacity × (target % − starting %) ÷ 100. For example, a 60 kWh battery from 20% to 80%: 60 × 60% = 36 kWh. Accounting for charging efficiency (≈ 90%), the actual grid consumption is about 40 kWh.

Can you charge an electric car on a standard plug?

Yes. A domestic 230V plug (type E or F) delivers about 2.3 kW, which is enough to charge an electric car. For a 60 kWh battery from 20% to 100%, expect about 24 hours. A standard plug is suitable for occasional or emergency charging, not for daily intensive use.

How long to charge with a 7 kW wallbox?

A 7.4 kW wallbox is the most common home charger in Belgium. For a 60 kWh battery from 20% to 80% (36 kWh net), expect about 5h30. For 40 kWh (city car battery) from 20% to 100%, about 5 hours. Overnight charging covers the vast majority of daily needs.

How long to charge on the motorway?

DC fast chargers on Belgian motorways (Ionity, Fastned, Electra, Q8 Charge) typically deliver between 50 and 350 kW. For a 60 kWh battery from 10% to 80%: about 50 minutes at 50 kW, 20 minutes at 150 kW, and under 10 minutes at 350 kW. Actual times vary depending on battery temperature and the vehicle's charge curve.

Can you charge an electric car in the rain?

Yes, completely safely. Charging connectors are designed to withstand weather conditions (minimum IP44 protection rating for public chargers). The electrical systems of electric vehicles are fully sealed. You can plug in and charge your vehicle in the rain without any risk.
