AC and DC Charging
Electric vehicles can be charged using Alternating Current (AC) or Direct Current (DC).
Understanding the difference will help you manage your time effectively and optimize charging costs.
AC Charging
Alternating Current
This is the primary charging method for home and work. The grid provides AC power, the vehicle’s On-board Charger converts it to DC to store in the battery.
- Power: 3.7 kW to 22 kW․
- Best for: Parking durations of 4 hours or more.
DC Fast Charging
Direct Current
DC stations are designed for speed. They bypass the car's internal converter and deliver power directly to the battery at high intensity.
- Power: 50 kW to 350+ kW․
- Best for: Long trips and quick top-ups․
What is the real difference?
The core difference is where the power conversion happens.
AC – Conversion happens inside the vehicle. It’s a gentler, slower process that is better for long-term battery health.
DC – Conversion happens inside the station. This allows for massive power delivery, significantly reducing wait times.
In Armenia, for the vast majority of EV owners, a home-installed AC Wallbox (7–22 kW) is the most efficient and cost-effective solution for daily use.
