EV Charging 101
Electric Vehicle Charging 101
Electric vehicle charging is simple, cost-effective and convenient. EV drivers have access to multiple options available to charge their vehicle.
Similar to filling a conventional powered vehicle with gasoline, an EVs battery is charged by plugging the vehicle into an electric vehicle charging station. Electric vehicle charging can take place at home, at work, at the grocery store or on the go.
Charging Equipment Types
Charging equipment for EVs is classified by the rate at which the batteries are charged. Charging times vary based on how depleted the battery is, how much energy it holds, the type of battery, and the charging equipment utilized.
Level 1: 120V
All electric and plug-in hybrid electric vehicles are equipped with a charging cable capable of charging the vehicle’s battery using a standard 120 volt (V) alternating current (AC) outlet. Level 1 charging is the slowest charging method and is typically conducted overnight at the vehicle owner’s home. However, Level 1 charging can take place anywhere a standard three prong electric outlet is available.
Level 1 charging adds roughly 3 to 6 miles of driving range for each hour spent charging.
Level 2: 240V
Level 2 equipment offers charging through a 240V, AC plug and generally requires the installation of home charging or public charging equipment. These units require a dedicated 40-amp circuit and charge the vehicle through the same connector location used for Level 1 equipment. Level 2 charging equipment is can be installed at residential locations, work places and public or private parking locations.
Level 2 charging equipment can typically provide 20 or more miles of all-electric range for each hour spent charging.
DC FAST CHARGING: 50-350KW
Direct-current (DC) fast charging equipment enables rapid electric vehicle charging with stations typically deployed along heavy traffic corridors. DC fast charging equipment provides charging through a 480 Volt service and is the fastest mode for charging an electric vehicle. While Level 1 and Level 2 charging is standardized, multiple charging plugs exist for DC fast charging. The three types of DC fast charging systems include the J1772 CCS Combo, CHAdeMO and Tesla connectors.
DC fast charging equipment can charge a vehicle’s battery to 80%, or provide 60 to 150 miles of range, in roughly 30 minutes of charging.
