EV charging equipment is categorized by the rate at which batteries recharge, and charging times vary based on several factors, including battery state-of-charge and charger type. Here’s a brief overview of the types of charging equipment:
- AC Level 1 Charging
-
- Charge Rate: Approximately 5 miles of range per hour.
- Specifications: Utilizes a standard 120-volt outlet via a J1772 connector. Level 1 is primarily for home charging and requires no additional equipment.
- AC Level 2 Charging
-
- Charge Rate: Approximately 25 miles of range per hour.
- Specifications: Operates on 240-volt electrical service (commonly used in residential settings). Predominantly installed for home and public charging stations, accounting for nearly 80% of public EV charging ports as of 2023.
- DC Fast Charging
-
- Charge Rate: Approximately 100 to 200+ miles of range in 30 minutes.
- Specifications: Involves high-power charging stations capable of rapid charging along key transportation routes. About 20% of public EV charging ports are DC fast chargers, increasing due to federal funding initiatives.
