EV Chargers Should Be Dumber

with an adapter that allows its cord to be plugged into any NEMA 14-50 outlet, common at RV parks and campsites all across the country.

I had never used one before, but it was stupendously simple at a nearby campground. I didn’t need a cellphone to open an app to connect to the charger and start my session. I just plugged in the car like I would my iPhone.

Charging wasn’t blisteringly fast — but it wasn’t slow either. Since the car and the cord are both self-limited to avoid overheating the power source, it maxed out at 9.6kW per hour. That’s not the 19.2 kW speeds the car is capable of, but it’s still very good, and stronger than the 6.6 kW found at many level 2 public chargers. Even considering the Lucid Air’s large 118 kWh battery, the rate I was charging would have been enough to go from about 15% to more than 80% overnight. An EV with a smaller battery could no doubt recharge completely in a shorter amount of time – the 9.6 KW supplied by that Lucid cord surpasses the AC charging speeds of some modern EVs.

The plug is not unique to Lucid either. Many EVs come standard with mobile charging cords that are capable of matching (or getting pretty darn close to) the maximum AC charging speeds the vehicle is capable of. If they aren’t supplied, it’s not hard to find a portable EVSE that can do so, for a few hundred dollars.

The key thing is that NEMA 14-50 standard outlet.

Couldn’t agree more - charging should be as simple as plugging in your toaster.
