About EV charging

DC fast charging, and AC charging at Level 2 and Level 1. See more details below.

Car Charging
Direct current (DC) fast charging stations, increasingly found in more public locations, are the most powerful chargers available at this time. They can re-charge your EV more quickly than Level 1 or Level 2 chargers, and in some cases, in less than 30 minutes.

The speed of charge at DC fast charging stations depends on the vehicle’s current state of charge, the limits of the vehicle’s battery, as well as a variety of other factors. Current DC fast chargers use the non-proprietary and universal standard Combined Charging System (CCS), so named because the CCS integrates the connector plug, the managing of control functions, and the charging communication between electric vehicle and the charging infrastructure.

Another global standard charging technology, CHAdeMO, is the trade name of a DC charging method for electric vehicles, delivering up to 62.5 kW through a special electrical connector. Electrify America is bringing the fastest DC fast chargers to the market to date, and will offer 50kW up to 350kW from the same chargers on our highways, and from 50kW to 150kW for our metropolitan based charging sites. At 150kW, you can typically expect about 9 miles of range per minute of charge versus 3 miles of range per minute from a 50kW charger.

New electric vehicles coming to market will be able to accept 100kW or more charging power, and Electrify America chargers will be ready to support this technology.

DC fast charging is rapidly becoming available.

DC fast chargers have multiplied rapidly across the United States, and nearly 2,000 sites are available for EV drivers today.5 It is planned that by July 2019, Electrify America will add nearly 500 more sites to this total. This should provide even greater accessibility for EV drivers today, or those wondering if there are enough chargers in the future.

AC Charging is important too.

AC chargers, referred to as Level 2 (L2) and Level 1 (L1) chargers, typically found in home and workplace settings, as well as many public locations, use an on-board charger on the inside of the car to deliver electricity to charge the vehicle’s battery. This on-board charger converts AC electricity to DC electricity, which is fed directly into the battery.

L1 and L2 chargers are typically less expensive and easier to install than DC fast chargers, and use power often found in the home, 120V for L1 or 240V for L2, which is the common power rating for electric dryers. These chargers fill an EV at speeds that offer 3.3 to 7.2kW of power, and are typically plugged in overnight or during the day at a workplace charger.

L2 chargers typically feature a non-proprietary J1772 connector that allows nearly universal connection between the chargers and electric vehicles using the AC charging port.
