Electric Car Costs and Charging Patterns: Insights from a Tesla Model 3 User

As the world shifts towards more sustainable modes of transportation, electric cars have become increasingly popular. Understanding the costs and charging patterns of these vehicles is essential for both new and existing electric vehicle (EV) owners. This article provides an in-depth look at the cost of charging an EV, specifically using a Tesla Model 3 as a case study, and how often one needs to charge it. By sharing data from my recent experiences, I aim to offer practical insights that can help other EV owners optimize their charging habits.

How Much Does it Cost to Charge an Electric Car?

Charging an electric car can vary significantly depending on several factors, including the type of vehicle, the location, and the frequency of use. For one particular Tesla Model 3 in the Seattle area, the average cost of charging has been quite favorable. Over the past five years, I have driven 42,006 miles with an average electricity cost of 0.03709 per mile. This data is primarily based on home charging and is supplemented by occasional use of Superchargers.

Home Charging Statistics

When I return home, I plug the car in, ensuring it stays charged except when I'm out driving. I typically set the charging level to 70% as my driving habits largely revolve around a few miles from work and local shopping. This strategy has effectively eliminated range anxiety and made it easier to plan ahead, especially when using Tesla Superchargers for longer trips.

Over the period from December 2017 to March 2023, I used a total of 12,749 kWh of electricity from the car's battery. This translates to an average of 0.303 kWh per mile. Taking into account an estimated battery loss of 10%, the actual cost of charging at home is around 0.03709 per mile. This data suggests that if I were to track the costs of Supercharging, the total average cost per mile would be even lower.

Impact of Seasonal Changes and Tire Efficiency

The energy consumption of an electric vehicle can vary based on seasonal changes and tire performance. In the colder winter months, for instance, the energy consumption per mile generally increases. This can be attributed to the need for the car to generate more heat and resist lower temperatures, which drains the battery faster.

Another significant factor is the type of tires installed on the vehicle. In the fall of 2021, I switched to Cross Climate 2 tires for better traction in wet and snowy conditions. While the energy consumption per mile increased due to the reduced efficiency of these tires, this trade-off was deemed worthwhile due to the enhanced safety they provide.

Charging Frequency and Battery Health

For optimal battery health, it is recommended to never fully deplete the battery and to avoid charging it beyond 80%. I follow this recommendation with my Tesla Model 3, as the battery is designed to last longer if maintained within these parameters. I rarely charge the Tesla beyond 80.8%, and my daily driving consumes just a few percent of the battery, leaving ample capacity for longer trips without needing a charge.

Regarding the costs, I have found that charging every time I return home is the most practical approach. This method ensures that the car is always ready for use and reduces the risk of running out of charge, even for occasional long drives. However, it is important to note that the overall cost is still quite manageable, especially with the use of local electricity rates.

Conclusion

Charging an electric car, such as a Tesla Model 3, can be both economical and environmentally friendly. By understanding the drivers of cost and charging frequency, EV owners can make informed decisions that optimize their driving experience. Whether it's minimizing energy consumption through efficient use of tires or ensuring regular charging to maintain battery health, the key is to strike a balance that suits your lifestyle and needs.

For those considering or already driving an electric vehicle, the insights presented here can be a valuable resource. By closely monitoring charging patterns and costs, you can ensure that you are getting the most out of your EV while also contributing to a more sustainable future.
