The cost of charging a Tesla and how it compares to gas vehicles
Let’s assume you own the Model X with a 100 kWh battery and you pay the national average cost for power across the United States of 13 cents per kWh. Let’s also allow for a charging efficiency of 85% — that’s the usual efficiency for standard (Level 2) home charging stations, according to research studies.
Based on the above, it will cost $15.29 for a full charge. Given this car has a range of 295 miles, the cost per mile is 5.2 cents, or $5.20 per 100 miles driven.
What is the cost to charge a Tesla Model 3?
The long-range version of the Model 3 has a 75 kWh battery pack with a 310 mile range. If we still assume the average national electric pricing of 13 cents per kWh and a charging efficiency of 85%, then a full charge will cost $11.47. This is $3.70 per 100 miles of mixed city and freeway driving, or 3.7 cents per mile. This is almost 80% less than the cost per mile to drive the most popular gas-powered cars, which is approximately 20 cents per mile.
