Plug-in Electric Vehicle Charging: The Basics | US
You can plug your car directly into the 120 Volt outlet using the charge cable (technically called the Electric Vehicle Supply Equipment or
It uses standard household outlets providing 120 volts of AC power. These stations typically deliver 3-5 miles of range per hour of charging. While slow, Level 1 charging works well for plug-in hybrids or drivers with short daily commutes who can charge overnight.
Without robust DC electrical components, energy could not be efficiently or safely delivered to an EV's battery pack. Charging stations operate at different power levels, each designed for specific use cases and charging speeds. Understanding these differences helps you choose the right charging option for your needs.
Each level is defined by the amount of voltage, which directly correlates to the speed or quickness of the charging session. Level 1 Home Charging (120-volt) takes the most time to reach a full charge, followed by Level 2 Home and Commercial Charging (240-volt), and finally Fast or Public Charging (400-volt).
The power of a home charging station, measured in kilowatts (kW), impacts how quickly your EV can charge. This power is calculated by multiplying the voltage (V) by the amperage (A). In North America, Level 2 home charging stations are typically plugged into 220-240V outlets, making both voltage and amperage key factors in charging speed.
