How long does it take to charge an EV?

Work out the energy you need

Charging time depends on the energy you want to add and the power the car actually accepts. Battery capacity is measured in kWh; charging power is measured in kW. They describe different things.

Approximate energy to add = usable battery capacity × change in charge level. For an illustrative 60 kWh usable battery, moving from 20% to 80% adds about 36 kWh to the battery. The charger may bill more energy because charging has losses.

AC charging: the car’s onboard limit matters

AC electricity is converted inside the vehicle. Practical power is limited by the car’s onboard charger, the supply and the charging equipment. A 22 kW AC point cannot make a car with an 11 kW AC limit charge at 22 kW.

The 60 kW example is arithmetic for an assumed average DC session, not a claim that a particular car will maintain that power.

DC charging: peak power is not the session average

A DC charger supplies direct current to the battery. The vehicle controls how much power it accepts. Power can change with starting charge, temperature, battery conditioning, vehicle limits and charger sharing.

A quoted peak is reached only under suitable conditions and may last for only part of a session. Charging often slows as the battery fills, so a published 10–80% time should not be extended directly to predict a full 0–100% charge. Use the manufacturer’s figures for the exact variant, then compare them with your own sessions.

Choose a stop that fits your day

For a long parking stay, compare the energy that an AC charger can add during the time you already have. For a short stop, check the car’s DC capability and likely starting battery level. The fastest charger on the map may offer no benefit if your car cannot use its extra power.

• Check the usable battery capacity and AC/DC limits for your exact car.
• Choose a target charge level using the manufacturer’s guidance.
• Allow extra time for queues, setup and any taper near your target.
• Review actual kWh added and duration after each session to improve your estimate.
