The supply circuit required protection at 125% of the maximum rated current for example, charging equipment rated at 16 amperes ("amps" or "A") continuous current required a breaker sized to 20 A. Under the 1999 NEC, Level 1 charging equipment (as defined in the NEC handbook but not in the code) was connected to the grid through a standard NEMA 5-20R 3-prong electrical outlet with grounding, and a ground-fault circuit interrupter was required within 12 in (300 mm) of the plug.

The National Electric Transportation Infrastructure Working Council (IWC) was formed in 1991 by the Electric Power Research Institute with members drawn from automotive manufacturers and the electric utilities to define standards in the United States early work by the IWC led to the definition of three levels of charging in the 1999 National Electric Code (NEC) Handbook. Voltage and power Early standards NEC(1999) levels : 9 Method uses the term charging station as the location of a group of chargers, and the term connector for an individual charger. electric vehicle connectors, attachment plugs, and all other fittings, devices, power outlets, or apparatuses". NEC-1999 also defined the term "electric vehicle supply equipment" as the entire unit "installed specifically for the purpose of delivering energy from the premises wiring to the electric vehicle", including "conductors. The terms "electric vehicle connector" and "electric vehicle inlet" were previously defined in the same way under Article 625 of the United States National Electric Code (NEC) of 1999.
Most fully electric car models can accept both AC and DC power.Ĭharging stations provide connectors that conform to a variety of international standards. DC fast chargers facilitate higher power charging, which requires much larger AC-to-DC rectifiers, so the converter is built as part of the charging station and DC power is supplied directly to the vehicle, bypassing the onboard converter. At an AC charging station, power is supplied to the onboard charger. For this reason, most electric vehicles have an onboard charger with an AC-to-DC converter (a rectifier). Batteries can only be charged with direct current (DC) electric power, while most electricity is delivered from the power grid as alternating current (AC). There are two main types: AC charging stations and DC fast chargers.
