Electric Vehicle FAQ
How long does it take to charge?
Charging times for EVs depend on a range of factors, such as what kind of connection you have access to and the size of the battery, as well as the outside temperature and a range of external factors.
In general, there are two types of charging: normal alternating current (AC) charging and fast direct current (DC) charging. Normal AC charging is typically less energy-intensive and therefore much slower than fast charging. When you charge at home using a conventional plug, or sometimes when you plug into publically available street charging, you will be using AC. Fast charging can be completed in under an hour and is typically only found at public charging stations. Take the Hyundai KONA Electric for example: when plugged into a 100kW DC fast charging station, 54 minutes is all it takes to get to 80% state of charge.
Normal charging with alternate current (AC) can be done at wall-mounted home charging stations, commonly called “wall-boxes” which typically provide a charge of up to 22 kW (depending on market). The (AC) charging times depend also on the size and age of the battery, as well as on the capacity of the vehicle’s on-board charger. The on-board charger converts the AC energy from your wall-box, into DC energy that can be stored in the High Voltage battery. For example, the Hyundai KONA Electric can be fully charged in 7 hours and 30 minutes with the optional 10.5kW 3-phase on-board charger, which is ideal for overnight charging. The IONIQ Plug-in, with its smaller battery and less powerful 3.3kW single-phase on-board charger, doesn’t take quite as long and can be re-charged in 2 hours and 15 minutes.
Fast charging with direct current (DC) is typically only available for BEVs, such as the Hyundai KONA Electric. Most fast-charging stations provide a charge of above 22 kW, with some stations providing a charge of 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 20% to 80% charge in less than an hour. Of course, this varies from station to station and depends on the maximum charging speed the vehicle supports. It is important to note that colder temperatures can slow down electricity flow and thus increase the charging time.
