When it comes to charging electric vehicles (EVs), there are two main types: **AC (Alternating Current) chargers** and **DC (Direct Current) chargers**. Understanding their differences can help EV owners choose the right charging solution.
Charging Speed
AC chargers are slower because the vehicle’s onboard converter must transform AC power into DC to charge the battery. These are commonly used at home or workplaces. In contrast, **DC fast chargers** supply power directly to the battery, enabling much faster charging—ideal for public stations and long trips.
Power Supply & Infrastructure
AC chargers use standard grid power (120V or 240V), while DC chargers require high-voltage connections, making them more expensive to install. However, companies like **AFAX Power** are innovating in this space with efficient DC charging solutions. Learn more at [www.afaxpower.com](www.afaxpower.com).
Typical Use Cases
- **AC Chargers**: Best for overnight charging at home.
- **DC Chargers**: Perfect for highway rest stops and quick top-ups.
Cost & Efficiency
AC charging is cheaper but less efficient for fast charging. DC charging, while costlier, reduces downtime significantly.
Compatibility
Most EVs support AC charging, but DC fast charging depends on the vehicle’s capability (e.g., CCS, CHAdeMO, or Tesla Supercharger).
