• Standard charging
• Fast charging
• High-power charging

The actual charging rate depends on the charger, vehicle, battery, electrical supply and operating conditions.

4. AC Charging

AC, or alternating-current charging, supplies AC electricity to the vehicle.

In many AC charging systems, the vehicle's onboard charger converts AC electricity into DC electricity that can be stored in the battery.

AC charging is commonly associated with:

• Residential charging
• Workplace charging
• Long-duration parking
• Destination charging

The charging speed varies according to the vehicle and charging equipment.

5. DC Fast Charging
