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

Home 1 (120V) – extension cord

  • 120V standard outlet plug (actual voltage: ~117V)
  • Extension cord + portable charger
  • Extension Cord: Clear Power 50ft 10/3 SJTOW extra heavy-duty weather resistant extension cord
