1. What is Miles per KWH?

Miles per kilowatt-hour (miles/kWh) is a measure of how efficiently an electric vehicle uses energy. It indicates how many miles the vehicle can travel using one kilowatt-hour of electrical energy.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• Miles Driven — Distance traveled in miles
• Kilowatt-hours Used — Energy consumed from the battery

Explanation: Higher values indicate better efficiency, meaning the vehicle travels further using the same amount of energy.

3. Importance of Efficiency Measurement

Details: Tracking miles/kWh helps Tesla owners understand their vehicle's performance, estimate range more accurately, and identify changes in efficiency that might indicate maintenance issues.

4. Using the Calculator

Tips: For accurate results, reset your trip meter after charging and record miles driven and kWh used from your energy app or charging data. Ideal measurements come from full charge cycles.

5. Frequently Asked Questions (FAQ)

Q1: What's a good miles/kWh for a Tesla Model 3?
A: The Model 3 typically achieves 3.5-4.5 miles/kWh, with higher numbers indicating better efficiency.

Q2: Why does my efficiency vary?
A: Factors like driving speed, temperature, terrain, climate control use, and tire pressure all affect efficiency.

Q3: How can I improve my Tesla's efficiency?
A: Maintain proper tire pressure, avoid aggressive acceleration, use regenerative braking, and minimize high-speed driving.

Q4: Does this account for charging losses?
A: No, this calculates efficiency based on energy used while driving. Charging efficiency is separate.

Q5: How does this compare to MPGe?
A: MPGe converts kWh to gallons of gasoline equivalent. 33.7 kWh = 1 gallon equivalent, so 100 MPGe ≈ 2.97 miles/kWh.
