Electric Vehicle Chargers
The Different Levels Of Electric Vehicle Charging:
Level 1 - Level 2 - Level 3
Level 1
Uses a common 120-Volt household outlet. Estimated Charging Speed: 2 to 6 Miles Per Hour.
Level 2
Uses 208-240 Volt. It is the most commonly used level for daily EV charging. Level 2 charging equipment can be installed at home, at the workplace, as well as in public locations. Estimated Charging Speed: 12 to 80 Miles Per Hour
Level 3
Uses 400-Volt to 900-Volt (DC Fast Charge & Supercharging). Estimated charging Speed: 3 to 20 miles per minute (180+ Miles Per Hour). Commercial locations.
In-Home EV Chargers
The two most commonly installed (Level 2) EV charging station types:
1. Standard Plug-in Chargers
Require a NEMA 14-50R. It is a 120/240Volt 50Amp receptacle permanently installed, typically in the garage (or on the outside of the building). The charging station plugs into the NEMA 14-50R (R=receptacle), with a factory-installed cord on the charger.
Examples of these chargers are:
- ChargePoint Home Flex EV Charger
- Tesla Mobile Connector
- Lectron NEMA 14-50 EV Charger
(We are not affiliated with either of these EV Chargers, but these are the most commonly used)
They typically charge between 32Amp to 40Amp (240V)
PROS:
- could be mobile
- use the standard NEMA 14-50R
CONS:
- slower charging (compare to the hard wired EV chargers)
- after the adaption of NEC 2020, all 240V receptacles in garages need GFCI protection, therefore the installation usually cost more than the hard wired charging station. NEC 210.8(A)
2. Hard Wired EV Chargers
Require a hard-wired connection and the charging station is permanently mounted on the wall, typically inside of the garage.
Examples of these chargers are:
- ChargePoint Home Flex EV Charger (when hard wired)
- Tesla Wall Connector
(We are not affiliated with either of these EV Chargers, but these are the most commonly used)
PROS:
- about 20-50% faster charging (compare to the NEMA 14-50R chargers)
- no need GFCI protection in the electrical panel (cost efficient installation)
CONS:
- the charger may cost more than the Plug-in EV charger (however some models offer both hardwire and NEMA configurations)
- hard wired installation requires a permanent location (attached to the the wall and the charger won't be mobile)
