1. What is Miles per kWh?

Miles per kilowatt-hour (mi/kWh) is a measure of electric vehicle efficiency, showing how many miles an EV can travel using one kilowatt-hour of electricity. It's the electric equivalent of miles per gallon (MPG) for gasoline vehicles.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• Miles Driven — Distance traveled by the electric vehicle
• kWh Used — Electrical energy consumed during the trip

Explanation: This ratio shows how efficiently the vehicle converts electrical energy into distance traveled.

3. Importance of Miles per kWh

Details: This metric helps EV owners understand their vehicle's efficiency, estimate charging costs, and compare different EV models. Higher values indicate better efficiency.

4. Using the Calculator

Tips: For accurate results:

• Reset your trip meter when fully charged
• Note the kWh used from your vehicle's energy display
• Use data from a full charge cycle for best results

5. Frequently Asked Questions (FAQ)

Q1: What's a good miles per kWh value?
A: Most EVs get 2-4 mi/kWh. Efficient models may achieve 4-5 mi/kWh, while performance EVs might get 1.5-3 mi/kWh.

Q2: How does this compare to MPGe?
A: MPGe converts kWh to gallons of gasoline equivalent (33.7 kWh = 1 gallon). 100 MPGe ≈ 3.3 mi/kWh.

Q3: Does weather affect mi/kWh?
A: Yes, cold weather can reduce efficiency by 20-40% due to battery performance and cabin heating.

Q4: How can I improve my EV's efficiency?
A: Drive at moderate speeds, use regenerative braking, minimize HVAC use, and keep tires properly inflated.

Q5: Should I use wall kWh or battery kWh?
A: For cost calculations, use wall kWh (includes charging losses). For vehicle efficiency, use battery kWh.
