___ charging uses 208 or 240 volts and is able to charge an electric vehicle's battery in 4-6 hours.

• A. Residential
• B. Level 2
• C. DC Fast
• D. Wireless

Answer: (B)

Level 2 charging is defined by using a higher-voltage supply, typically 240 volts (208 volts in some commercial settings). That higher voltage lets the vehicle’s onboard charger pull more current compared to a standard household outlet, so you can charge a sizable EV battery in a few hours. The 4–6 hour window fits a typical Level 2 session for many mid-size batteries, though exact times depend on the battery size and the charger’s power rating. By comparison, Level 1 charging uses a standard 120-volt outlet and charges much more slowly, often taking many hours or overnight. DC Fast charging uses direct current at much higher voltages (and far higher power) to charge in minutes. Wireless charging is another method that uses inductive power transfer and isn’t defined by this 208/240-volt, 4–6 hour pattern.
