Amperage:
Level 2 (240-volt) EV chargers have max amp outputs ranging between 16-80 amps. Popular units are between 40 and 48 amps because most EVs can charge at 48 amps or less. Most home charging stations can be programmed to operate at lower amp modes if needed. Level 1 (120-volt) EV charging cables usually operate at […]
App Control:
Many “smart” networked EV chargers have downloadable mobile apps for remote management and monitoring. Others may have a simple web interface.
Cord Length:
We’ve seen EV charging stations come with cords ranging between 17 and 25 feet. A longer cord is more cumbersome to handle but will offer more parking options, and will reach an EV parked in an adjacent spot.
EV Connector:
EV Connectors in North America: J1772 is used for most EV models other than Teslas. In the longer term, J1772 is expected to become less popular, but adapters exist to convert J1772 to NACS and vice versa. NACS, also known as the Tesla plug. This connector is used by Tesla cars, and it will be […]
Home Connection:
Many Level 2 EV charging stations can be plugged into NEMA 14-50 or NEMA 6-50 outlets that supply 240 volts. EV charging stations can also be “hardwired” directly to the circuit breaker by a licensed electrician. Some are designed only for hardwiring and do not include input cables.
NEMA 3R
NEMA 3R rated enclosures can be installed inside or outside. However, these enclosures should be installed outdoors under protection from heavy rain as water may still enter inside.
NEMA 4
NEMA 4 rated enclosures can be safely installed outside. These are designed to protect against falling rain, snow, external ice formation, and dust. These usually lack gasket sealing that come with NEMA 4X enclosures.
NEMA 4X
These are some of the toughest EV charger enclosures available. The same level of protection as NEMA 4, but with additional gasket seals and a higher ability to withstand corrosion. NEMA 4X enclosures are suitable for extreme environments.
Networking:
Smart EV charging stations can connect to the internet via Wi-Fi or to your mobile device via Bluetooth for remote control and monitoring. Some products use powerline networking instead.
