What is slow charging?
Slow charging usually means lower-power AC charging, such as 3.5 kW, 7 kW, 11 kW, or 22 kW. It works well at homes, offices, apartments, hotels, and places where the car is parked for several hours.
Its strength is convenience. Its limitation is time: charging can take several hours depending on battery size and charger power.
What is fast charging?
Fast charging usually means DC charging. In a DC charger, power conversion happens in the charger itself, allowing higher power to flow directly to the battery.
Public DC chargers around 60-120 kW are commonly used for destination charging, travel corridors, and locations with high vehicle turnover.
Why charging speed changes
Maximum charger power is not the only factor. The vehicle has its own acceptance limit, and battery temperature, system condition, and state of charge all affect speed.
Many EVs charge fastest when the battery is lower, then slow down near 80% and even more near full. This is normal and helps protect the battery.
When to choose AC or DC
Choose AC when the vehicle will be parked for a long time. Choose DC fast charging when you are traveling, on a tight schedule, or need range quickly.
Using both gives the best ownership experience: AC for routine charging, DC for quick mobility.
