2023 Battery Electric Vehicle (EV or BEV) Driving and Fuel Statistics

Writ­ten 4/29/23 — Updat­ed 2/21/2024

Purpose

Report­ing on Trip and Fuel Sta­tis­tics for dri­ving a bat­tery elec­tric vehi­cle (BEV). Specif­i­cal­ly the 2023 Ford Mus­tang Mach-E4

Location

North­ern VA

What

Data obtained from In-car Dash, Ford­Pass App, Charg­ing Sta­tions, and Home Charg­er

Duration

As long as I own the vehi­cle. Start Date: Jan­u­ary 21, 2023

Notes

This is pri­mar­i­ly City dri­ving with mod­er­ate traf­fic

ADJ: “Adjust­ed” — Adjust­ed for a par­tic­u­lar trip’s bat­tery capac­i­ty which is gov­erned by fac­tors such as tem­per­a­ture. Every EV has an ide­al bat­tery capac­i­ty. This can be exceed­ed or under­cut, which there­fore affects the rest of met­rics like MPGe and ener­gy effi­cien­cy.

Aver­age Trip Speed: Not aver­age speed dri­ven dur­ing trip, but speed when tak­ing into account miles dri­ven and time dura­tion of trip

MPGe: Based off the EPA con­ver­sion: 33.705kWh elec­tric­i­ty = 1 gal­lon gaso­line

Aver­age Tem­per­a­ture: As report­ed by Weath­er Under­ground His­tor­i­cal Data for Dulles Air­port
