FAQ

Level 2 chargers (AC) operate at 208–240V and deliver significantly higher power than Level 1, making them a common choice for homes and businesses. DC fast chargers (Level 3/DCFC) are typically used in public settings for rapid charging.

Most Level 1 and Level 2 chargers use the SAE J1772 (Type 1) connector. Tesla vehicles use the NACS connector but include an adapter for compatibility with J1772 chargers. For DC fast charging, common standards include CCS and, in some cases, CHAdeMO.

A typical Level 2 charging station provides around 7.2–7.6 kW, which usually adds 20–25 miles (30–40 km) of driving range per hour. Depending on the charger and vehicle, Level 2 charging can range from about 3 kW up to 19 kW.

Charging costs depend on electricity rates and vehicle efficiency. For example, at $0.13/kWh and an efficiency of 27 kWh/100 miles (0.27 kWh/mile), the cost is about $0.035 per mile, or roughly $7 for 200 miles of driving.

OCPP (Open Charge Point Protocol) is a communication standard that allows EV chargers and management software to work together, providing interoperability and advanced features.

Circuit breakers should be sized at 125% of the charger’s current. For example: a 32A charger requires a 40A breaker, a 40A charger requires a 50A breaker, and a 48A charger requires a 60A breaker. Always consult a licensed electrician for installation.

Public charging prices vary by network and pricing model. Many charge per kWh, typically between $0.30 and $0.60, while some also apply per-minute or per-session fees.

Prices for EV charging stations vary depending on power level, features, and configuration. Entry-level commercial Level 2 units start from around $2,700, while dual-port or advanced models with RFID or display features typically range between $3,000 and $4,000. For DC fast charging, costs are higher, usually starting from around $12,000.
