There are ___ types of electric vehicle chargers.

• A. 3
• B. 4
• C. 1
• D. 2

Answer: (A)

Charging for electric vehicles is commonly grouped into three main levels based on the electrical supply and how fast they charge: Level 1 uses standard 120 V AC from a regular outlet, which is the slowest option and typically used for overnight top-ups. Level 2 runs on 240 V AC with higher current through a dedicated EV charging circuit, offering much faster charging for home or public installations. Level 3, known as DC fast charging, delivers direct current at high voltages from specialized equipment, allowing rapid charging at public stations or commercial sites. These three categories cover the typical charging scenarios encountered in most electrical practice, and there aren’t four primary types in this standard framework.
