Tesla v. Mustang: Sample Charging Costs

The cost of charging an electric vehicle (EV) can vary based on several factors, including the specific EV model, charging location, electricity rates, and time of charging. Here are two examples to provide an estimate of charging costs for a Tesla in Florida and a Ford Mustang Mach-e in Missouri, using relevant utility rates and charging costs:

Example 1: Tesla Model 3 in Florida

  • Vehicle: Tesla Model 3
  • Location: Florida
  • Utility Rate: Florida Power & Light (FPL) residential rate
  • Charging Method: Home charging using a Level 2 charger
  • Electricity Rate: $0.12 per kilowatt-hour (kWh)

Tesla Model 3 has an EPA-estimated range of 263 miles for the Long Range version. Assuming a full charge from 0 to 100% and an average efficiency of 4 miles per kWh, the calculation would be as follows:

  • Total energy required for a full charge: 263 miles / 4 miles per kWh = 65.75 kWh
  • Charging cost: 65.75 kWh * $0.12 per kWh = $7.89

Example 2: Ford Mustang Mach-e in Missouri

  • Vehicle: Ford Mustang Mach-e
  • Location: Missouri
  • Utility Rate: Ameren Missouri residential rate
  • Charging Method: Public fast charging station (DC Fast Charger)
  • Electricity Rate: $0.30 per kilowatt-hour (kWh)

Ford Mustang Mach-e has varying battery capacities depending on the trim level, with the Extended Range version having an EPA-estimated range of 305 miles. Assuming a 10-80% charge at a fast charging station and an average efficiency of 3 miles per kWh, the calculation would be as follows:

  • Total energy required for the charge: 305 miles * (80% – 10%) / 3 miles per kWh = 6.97 kWh
  • Charging cost: 6.97 kWh * $0.30 per kWh = $2.09

Please note that electricity rates and charging costs can vary based on utility providers, time of use rates, and other regional factors. It is advisable to consult with the specific utility provider and check the charging costs associated with the chosen EV and charging method for accurate and up-to-date information.
