Part 3 of my three-year review covers: Energy Use and Carbon Emissions from driving 42,500 miles in our Model 3. Links to Parts 1-4 of the review are at the bottom.
We drove 42,500 miles in the first three years. I calculated how many kWh of electricity were sent to my car to charge the battery pack, and from that I estimated carbon emissions from producing the electricity.
I don’t have a separate meter to record energy use by my home charging station so I started with the amount of energy that the car reported using, and worked back from there. I took into account charging inefficiencies and estimated energy use by BMS and Sentry Mode – the UI currently reports energy use while driving. This is a back of the envelope estimate so keep in mind that YMMV.
11,100 kWh of electricity were used to charge my car over 3 years.
Here’s how I came up with...
