EV charging time and cost
How long to charge from 20 to 80% depending on the charger, and what it costs.
How it works
Energy = battery × (target − start) / 0.9 (charging losses). Time = energy / power; on fast chargers, power drops above 80%, which is why stopping there is best.

Worked example
With the default values:
- Battery capacity (kWh)60
- Starting charge (%)20
- Target charge (%)80
- ChargerWallbox / charger 11 kW
- Price per kWh0.32
- Consumption (kWh/100 km)17
you get:
- Charging time3 h 38
- Energy used40 kWh
- Charging cost€12.80
- Range added212 km

What do I need to enter?
Just fill in: battery capacity, starting charge, target charge, charger, price per kwh, consumption. The result updates as you type.
Can you give an example?
Battery capacity (kWh): 60; Starting charge (%): 20; Target charge (%): 80; Charger: Wallbox / charger 11 kW; Price per kWh: 0.32 → Charging time: 3 h 38; Energy used: 40 kWh.
