1. What is kWh per Mile?

kWh per mile is a measure of energy efficiency for electric vehicles, representing how much electrical energy is consumed to travel one mile. It's the electric vehicle equivalent of miles per gallon (MPG) for gasoline-powered cars.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• kWh — Kilowatt-hours of energy consumed
• Miles — Distance traveled

Explanation: This calculation gives you the average energy consumption per mile, which is useful for comparing efficiency between different electric vehicles or driving conditions.

3. Importance of Energy Efficiency Calculation

Details: Knowing your kWh per mile helps estimate charging costs, compare vehicle efficiency, and understand how driving habits affect energy consumption. Lower values indicate better efficiency.

4. Using the Calculator

Tips: Enter total energy consumed (from your charging station or vehicle display) in kWh and the distance traveled in miles. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a good kWh per mile value?
A: Most EVs get 0.25-0.35 kWh/mile. Values below 0.25 are excellent, while above 0.35 may indicate less efficient driving or conditions.

Q2: How does kWh/mile compare to MPGe?
A: MPGe (Miles Per Gallon equivalent) is another efficiency metric. 33.7 kWh = 1 gallon of gasoline equivalent, so 100 MPGe ≈ 0.337 kWh/mile.

Q3: Why does my kWh/mile vary?
A: Factors like speed, temperature, terrain, and accessory use (like AC) affect efficiency. Highway driving typically uses more energy per mile than city driving.

Q4: Can I calculate cost per mile from this?
A: Yes! Multiply kWh/mile by your electricity cost per kWh. For example, at $0.15/kWh and 0.30 kWh/mile: $0.15 × 0.30 = $0.045 per mile.

Q5: How accurate is this calculation?
A: It's accurate for the data you input. For best results, measure over multiple trips or charging sessions to get an average.
