YouTuber Drove 10,000 Miles In A Tesla Model 3 For Just $200
How much does it cost to charge & drive a Tesla Model 3 compared to buying gas? YouTuber Andy Slye’s Model 3 has covered 10,400-lifetime miles and it’s averaging 233 Wh/mile. So far he’s only spent $20.29 on four Supercharging sessions, and that resulted in approximately 700 miles of range which means the other 9,700 miles traveled were from charging at home.
To find out how much it’s cost to travel those 9700 miles we need to calculate my electricity rate along with the Tesla Model 3 charging efficiency. Andy’s off-peak electricity rate when charged at home is $0.06882 per kWh.
However, 100% of the electricity doesn’t make it into the car’s battery when charging at home. This is true for all-electric cars.
Edmund’s is doing a long-term test drive of the Tesla Model 3 and they’re measuring the average wall-to-wheels efficiency.
So far from their tests, they’ve seen an 83.3% charging efficiency (meaning only about 83% of the electricity makes it from the charging cable into the car battery).
Consider also the amount of battery that depletes as the Model 3 is just sitting somewhere not plugged in (generally at around 3% is for vampire drain), that brings around 80% total charging efficiency.
