1. What is the EV Cost Equation?

The EV cost equation calculates how much it costs to drive an electric vehicle per mile based on your electricity rate and your vehicle's energy efficiency.

2. How Does the Calculator Work?

The calculator uses the EV cost equation:

\[ \text{Cost per mile (\$)} = \text{Electricity rate (\$/kWh)} \times \text{Energy consumption (kWh/mile)} \]

Where:

Explanation: The equation multiplies what you pay for electricity by how much electricity your vehicle uses to determine your driving cost per mile.

3. Importance of Cost Calculation

Details: Knowing your cost per mile helps compare EV operating costs to gasoline vehicles and understand your charging expenses.

4. Using the Calculator

Tips: Enter your electricity rate (check your utility bill) and your vehicle's energy consumption (available in your EV's dashboard or manual). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Where can I find my electricity rate?
A: Check your utility bill - it's typically listed as "price per kWh" in the charges breakdown.

Q2: What's a typical energy consumption for EVs?
A: Most EVs use between 0.25-0.35 kWh/mile, but this varies by vehicle and driving conditions.

Q3: How does this compare to gas vehicles?
A: EVs typically cost 3-5 cents per mile, while gas vehicles often cost 10-15 cents per mile (varies by gas prices and MPG).

Q4: Should I use my home rate or public charging rate?
A: For most accurate personal costs, use your home rate. Public charging often costs more.

Q5: Does this include charging efficiency losses?
A: No - the calculator uses the vehicle's reported consumption which already accounts for charging losses.
