Single-phase chargers typically range from 7.2 kW to 11 kW.

• A. 7.2 kW to 11 kW
• B. 22 kW
• C. 3 kW
• D. 44 kW

Answer: (A)

The amount of power a single‑phase charger can deliver is determined by the supply voltage and the available current on that single phase. In most regions the residential single-phase supply is about 230–240 volts. With typical dedicated EV charging circuits rated for roughly 30–50 amperes, you get roughly: - 230–240 V × 32 A ≈ 7.4–7.7 kW - 240 V × 40 A ≈ 9.6 kW - 240 V × 48 A ≈ 11.5 kW That places common single‑phase Level 2 charging in the ballpark of about 7.2 kW to 11 kW. Pushing higher power on a single phase would require increasing current beyond typical residential circuit ratings or using larger conductors and breakers, which isn’t practical for standard single‑phase setups. To reach numbers like 22 kW or 44 kW, you’d normally use a three‑phase supply, which distributes power across multiple phases. A lower, around 3 kW, option exists on smaller or older single‑phase configurations, but the typical single‑phase range you’ll encounter in practice is 7.2–11 kW.
