FAQ
AC chargers are a slower charging solution designed for regular, daily charging. They usually take about 5 to 8 hours to fully charge an EV from 0% to 100%. Since AC chargers use the same power levels as typical household outlets, they are ideal for homes, workplaces, hotels, and public parking areas—especially when the vehicle is parked for extended periods, such as overnight.
AC chargers deliver alternating current and rely on the car’s onboard charger to convert it to DC for battery charging. DC chargers, on the other hand, provide direct current directly to the battery, enabling much faster charging. AC is suited for homes and offices, while DC is ideal for quick stops like highways, gas stations, or fleet depots.
Charging speed depends on your EV’s battery and onboard charging system. Most full electric vehicles (BEVs) charge at around 7kW on AC, though newer models can support 11kW or more. Check your vehicle’s specs for exact limits. The charger will always charge at the lower limit between its capacity and your vehicle’s acceptance rate.
AC charging is slower but cost-effective—perfect for overnight home charging or long work hours. DC is much faster and suited for on-the-go charging, such as on highways. However, DC systems are more expensive and require stronger infrastructure.
They’re commonly found in places with high turnover and fast charging needs—like highway service areas, gas stations, shopping malls, and commercial buildings. Their main goal is to get drivers back on the road quickly.
Key features include charging speed, compatibility with your vehicle, and smart charging functions like energy monitoring and remote control via browser or app. E-FANER’s home chargers include all these features, offering a reliable and user-friendly charging experience.
DC charging is significantly faster because it skips the vehicle’s internal AC/DC conversion. However, the actual speed depends on factors like:
Battery state of charge: Charging slows down significantly after 80%, to protect battery health.
Temperature: Cold weather reduces battery charging speed.
Charger output power: Higher output = faster charging. For example, 15 minutes at 100kW can add 130 km, while 350kW can add up to 480 km.
Example: Charging at 50kW for an hour can add about 278 km of range.
Yes. Public chargers are built with multiple safety features—such as lightning protection, arc fault prevention, and leakage detection—to ensure safe operation even in bad weather.
Data security is also crucial. Many systems undergo cybersecurity certification to protect remote access and prevent potential risks. Users should still follow safety guidelines for proper use.
Home AC chargers require minimal maintenance, but regular inspections help ensure long-term reliability. Check cables and plugs routinely for wear or damage, and keep the unit clean. Under normal use, an AC charger can operate for years without repair. If issues arise, contact us for support.
