What is fast charging — and how is it different from normal charging?

Fast charging for an electric car means that you replenish the battery significantly faster than with regular charging at home or at work. The difference lies both in the technology and the effect on the electricity.

AC charging vs DC charging — what does it mean?

Normal charging takes place using alternating current (AC). Here, the car uses its internal charger to convert the electricity into direct current, which the battery needs. Power is normally 3—22 kW and a full charge takes from a few hours to overnight. Ideal for night charging or when the car is parked for a long time.

Fast charging is carried out using direct current (DC). Then the charging station itself does the conversion and sends the current directly to the battery. Power is significantly higher, often 50—350 kW. With DC fast charging, most electric cars can charge from 20 to 80% in 20—40 minutes — sometimes even faster depending on the car model and charging station.

When is fast charging most relevant?

• Long trips: Fast charging is ideal when you need to quickly charge along the highway or when driving longer.
• Commercial and service vehicles: For taxis, courier vans or corporate fleets, fast charging often becomes essential to keep the vehicles running throughout the day.
• Emergency refills: If you need to recharge quickly after forgetting the night or day's normal charge.‍

Time gain and power

• AC normal charge: 3-22 kW (6-12 hours for full charge).
• DC fast charging: 50—350 kW (20—40 minutes for 20— 80% charge; runs significantly faster than at home).
  Keep in mind that the car itself limits the maximum power it can receive, both at AC and DC.

Summary:‍

Fast charging gives you quick energy replenishments when time is tight — while normal charging (AC) is best for daily routines. Combine both charging modes for maximum flexibility and convenience.
