Level 1 Charging - Is That Still Relevant?
That puts the power output at just under 2 KW (120V * 16A = 1,920 Watts). The average light-duty EV has an efficiency of around 3.5 miles per kWh, so this station would add a whopping 7 miles of range per hour of charging. A 60 kWh battery pack in something like a Chevy Bolt EV would take 30 hours to fully charge from empty.
Why in the world would anyone want that?The answer is quite simple: When the vehicle will be sitting and charging for a long time, it doesn't matter.
For the site host, there are significant cost and infrastructure savings associated with this approach. If an airport long-term parking lot is already charging you a per diem rate, the energy costs are insignificant, so they can install an inexpensive "dumb" (i.e. non-networked) station. In fact, they can install a whole bank of them at a very competitive price compared to networked Level 2 chargers that require recurring maintenance contracts and network fees.
