What is the current use of 14-30 EV outlets?
A large proportion of American households have existing 14-30 outlets typically at the back of their garage used for washer or dryer outlets. Given their availability, EV and plug-in hybrid owners have made use of existing outlets.
Are 14-30 outlets powerful enough?
For plug-in hybrid vehicles, a NEMA 14-30 at a level 2 charge such as 24 amps is well suited for EV charging. It will charge a typical plug-in hybrid within 2-3 hours depending on battery size. For pure electric vehicles, smaller battery-size vehicles such as a bz4x are well suited to a 14-30 EV Charger. For larger vehicles such as a Ford F-150 with a 98 kilowatt batter, charging would take around 16 hours for a full charge.
How much range will a 14-30 outlet provide?
A NEMA 14-30 can supply up to 24 amps to the car’s battery per hour of charging. This equates to 5.76 kilowatts per hour (240V x 24A = 5.76 kW).
How much driving range is provided?
A 14-30 will provide around 20-23 miles of driving range per hour of charging (+/-15% depending on the vehicle, battery life, and temperatures). Plug-in hybrids will typically benefit from the full charge of power per hour since the acceptance rate (how much power a plug-in hybrid can take) is increasing.
Are there any other considerations when using a 14-30 as an EV outlet for EV charging?
If the outlet is routinely used for other purposes, it is better to get a separate, dedicated outlet installed. Plugging and unplugging 240-volt outlets is not recommended. The outlet should also be inspected by a licensed electrician prior to use for EV charging since the plug outlet will be providing 2-8 hours typically of continuous charging, which is longer than current or prior use of the plug.
Are 14-30 level 2 EV Chargers available as NACS and J1772?
Yes. We provide NACS (SAE J3400) level 2 EV chargers and J1772 EV Chargers. NACS EV charging cables are thinner due to the cooling technology and so are easier to maneuver. All of the key EV manufacturers in the U.S, South Korea and Japan have announced plans to move to the NACS connector, which will open up Tesla Superchargers to non Tesla vehicles.
Our NACS EV chargers provide 40amp powerful level 2 EV charging as do our J1772 EV Chargers.
Our AEFA NACS and J1772 EV chargers offer powerful, reliable EV Charging. Each product is supplied with a suite of useful EV Charging accessories. The AEFA EV Charger has adjustable power settings, which can help avoid unwanted breaker tripping and each EV Charger is fitted with a built-in breaker for extra safety.
