Attachment 1: Electric Vehicle (EV) Charging Glossary
Charger, or Electric Vehicle Supply Equipment (EVSE): A permanently installed device that can be plugged directly into an EV. Connection types vary and converters may be needed.
Receptacle: An outlet that can be used to charge an EV via portable charging equipment or which can be used to power a permanently installed charger.
Level 1 EV Ready: A parking space with the lowest level of charging, which requires 12 or more hours to reach a full charge. It consists of a dedicated (single purpose) standard 120-volt, 20-amp receptacle.
Level 2 EV Ready: A parking space with an electric circuit that can support a standard Level 2 charger, which has four times the power of a Level 1 charger. It typically provides an 80% charge in about 3 hours. It consists of a dedicated 208/240-volt, 40-amp circuit and receptacle that can be used by portable charging equipment or a permanently installed on-site charger.
Level 2 EV Capable: A parking space capable of supporting future Level 2 EV charging, which includes raceway and/or sheathed cable, panel capacity, and circuit breaker space for a 208/240- volt, 40-amp minimum branch circuit.
Low Power Level 2 Receptacle: A parking space with mid-level charging capacity that has half the power of Level 2 EV charging. It consists of a dedicated 208/240-volt, 20-amp circuit and receptacle that can be used by a portable charger. It is useful in situations where electrical capacity is limited and where slower charging times can be tolerated.
DC Fast Charger: A parking space with the highest level of standard charging for automobiles.
It can typically provide an 80% charge in 20 minutes. It requires a minimum circuit capacity of 400 volts and 100 amps.
