Electric vehicle charging times.

How long does it take to charge?

Fully charging an electric vehicle can take from just under an hour to several hours. Charging times depend on a range of factors, like the type of charging station, your car's battery size and on-board charger capacity, outside temperatures, and other external factors.

Normal AC and fast DC charging.

There are two types of electric vehicle charging: normal alternating current (AC) charging and fast direct current (DC) charging. Normal AC charging is typically less energy-intensive which makes it much slower. When you charge at home using a conventional plug or a wallbox, or even at some public stations, you will be using AC. Fast DC charging can be completed in under an hour and is typically only found at public charging stations.

Normal charging
Fast-charging

Normal charging with alternate current (AC).

Wallboxes for home charging typically provide up to 22 kW. Charging times also depend on the size and age of the battery, as well as on the on-board charger's capacity. The on-board charger converts AC into the DC energy that is stored in the vehicle's High Voltage battery. Plugging into a regular home socket also charges with AC current.

Fast-charging with direct current (DC).

When charging with direct current (DC) the vehicle’s on-board charger is bypassed, so charging can be much faster. Most fast-charging stations provide a charge of above 22 kW, with some going up to 150 kW (and next-generation fast-charging stations will deliver even up to 350 kW). With this extra power, most fast-charging stations can provide a charge up to 80% in less than an hour. Of course, this varies from station to station and depends on the maximum charging speed the vehicle supports.

What else affects charging times?

Here are some other factors to consider when figuring out charging times for your electric car.

On-board charger.

On-board chargers convert alternating current (AC) coming from the charging station into direct current (DC) that is stored in the vehicle battery. Hyundai on-board chargers support up to 10.5 kW.
Battery capacity.

The more energy the battery can store, the longer it takes to fully charge.
State of charge (SOC).

Batteries are charging much faster when their state of charge is between 20 and 80 %. Below or beyond this state of charge, batteries are charging slower.
Outside temperatures.

Cold temperatures slow down electricity flow and electric vehicles take longer to charge in cold climates (unless, of course, the charging takes place in a heated space).

KONA Electric
IONIQ Electric

KONA Electric with a 39.2 kWh battery.

With a battery capacity of 39.2 kWh and a 7.2 kW on-board charger (1-phased), it takes around 6 h 10 min to charge the KONA Electric from 0 to 100 % at a wallbox with 7.4 kW power (1-phased) and around 19 h at a domestic socket with an ICCB-cable (depending on actual domestic power supply and ICCB setting).
KONA Electric with a 64 kWh battery.

The KONA Electric with a battery capacity of 64 kWh and a 10.5 kW on-board charger (3-phased) takes around 7 h 30 min to charge from 0 to 100 % at a wallbox with 11 kW power (3-phased) and around 31 h at a domestic socket with an ICCB-cable (depending on actual domestic power supply and ICCB setting).

IONIQ Electric with a 38.3 kWh battery.

The latest IONIQ Electric with a battery capacity of 38.3 kWh and a 7.2 kW on-board charger (1-phased) charges from 0 to 100% in around 6 h 5 min at a wallbox with 7.4 kW power (1-phased) and needs around 19 h at a domestic socket with an ICCB-cable (depending on actual domestic power supply and ICCB setting).

KONA Electric
IONIQ Electric

KONA Electric with a 39.2 kWh battery.

With a battery capacity of 39.2 kWh, the KONA Electric takes around 54 min to charge from 0 to 80% at a fast-charging station with 100 kW power (DC). Equipped with a 10.5 kW on-board charger (3-phased) it takes around 4 h 50 min to charge from 0 to 100% at an AC public charging station with a minimum power of 11 kW.
KONA Electric with a 64 kWh battery.

With a battery capacity of 64 kWh, the KONA Electric takes around 54 min to charge from 0 to 80% at a fast-charging station with 100 kW power (DC). Equipped with a 10.5 kW on-board charger (3-phased) it takes around 7 h 30 min to charge from 0 to 100% at an AC public charging station with a minimum power of 11 kW.

IONIQ Electric with a 38.3 kWh battery.

It takes around 54 min to charge the IONIQ Electric from 0 to 80% at a fast-charging station with 100 kW power (DC). When using a public AC charging station with a minimum power of 11 kW, the 7.2 kW on-board charger (1-phased) allows to charge from 0 to 100% in around 6 h 5 min.
