L2 LEAF CHARGING

Level 2 Pedestal charging stations were recently added to our apartment parking lot, with 4 parking spaces & 4 charging cables from 2 units, that serve up 240v at 40amps or 9.6kW on the higher end of L2 charge rates 

I then discuss aspects of the aero efficient 2019 LEAF SV design that help to improve laminar flow & reduce turbulent vacuum losses, smoothing airflow around the vehicle, over & under it with features designed to reduce drag losses that improve battery electric range at higher speeds on the highway as aerodynamics becomes a significant part of vehicle energy consumption at speeds above 35 MPH & very significant above 50 MPG. It can take 2X as much energy to go 70 MPH as it does to go 50 MPH for example. 

Aerodynamic features of automobiles improve fuel economy or energy economy by reducing drag losses, enabling the vehicle to slip through the atmosphere near roadways in the biosphere of Earth efficiently! 

This important because the passenger cabin of a typical family car must be able to transport 4 adult humans & cargo like bags of groceries or luggage or a bicycle or snowboard or similar gear, requiring a 3D volume that tends to be rectangular in School Busses & many Box Trucks, as cargo carrying volume prioritized over aerodynamic efficiency, something that is way more important in passenger aircraft that travel 300-700 miles per hour where aero drag significantly effect fuel consumption of JET A which dominates the operating costs of airlines, even though they only pay $1/gal for Jet A while I have to pay $4.50 for a less energetic gallon of gasoline locally. 

A fully loaded passenger aircraft gets over 180 miles per gallon per person when you divide the fuel consumption vs distance covered by the total number of passengers transported. Our Nissan LEAF SV gets around 130 MPGe at slower speeds & 100 MPGe at highway speeds above 50 MPH.
