How many amps needed for electric car charger?
The number of amps needed for an electric car charger depends on the charging rate of the car and the charging capacity of the charger.
For Level 1 charging, which uses a standard 120-volt household outlet, the amperage is typically 12 amps, which provides a charging rate of about 4-5 miles of range per hour.
For Level 2 charging, which uses a dedicated 240-volt circuit, the amperage can range from 16 amps to 80 amps, depending on the charging capacity of the charger and the car's charging rate. The most common amperage for Level 2 chargers is 32 amps, which provides a charging rate of about 25-30 miles of range per hour.
For DC fast charging, which is the fastest charging option and is typically available at public charging stations, the amperage can range from 50 amps to 400 amps, depending on the charging capacity of the charger and the car's charging rate. DC fast chargers can provide a charging rate of up to 200-300 miles of range per hour, depending on the car and the charger.
It's important to note that the amperage requirements can vary depending on the specific car and charger being used. Therefore, it's important to consult the car's owner's manual or contact the manufacturer to determine the appropriate charging requirements. Additionally, it's important to ensure that the electrical system and wiring of the building or home can handle the amperage requirements of the charger.
