1. What is Miles per kWh?

Miles per kilowatt-hour (miles/kWh) is a measure of how efficiently an electric vehicle uses energy. It tells you how many miles the vehicle can travel using one kilowatt-hour of electricity. For the Tesla Model Y Long Range, typical values range between 3.5-4.5 miles/kWh.

2. How Does the Calculator Work?

The calculator uses a simple formula:

Where:

• Miles Driven — Distance traveled (miles)
• kWh Used — Energy consumed (kilowatt-hours)

Explanation: This ratio shows how efficiently your Tesla Model Y converts electrical energy into distance traveled.

3. Importance of Efficiency Calculation

Details: Tracking miles/kWh helps you understand your vehicle's performance, estimate range, and identify changes in efficiency due to driving habits or environmental factors.

4. Using the Calculator

Tips: For accurate results:

• Reset your trip meter after charging
• Use the energy consumption data from your vehicle display
• Calculate over multiple trips for more reliable averages

5. Frequently Asked Questions (FAQ)

Q1: What's a good miles/kWh for Model Y Long Range?
A: 4.0 miles/kWh is excellent, 3.5 is average, and below 3.0 suggests inefficient driving or conditions.

Q2: How does weather affect efficiency?
A: Cold weather can reduce efficiency by 15-30% due to battery performance and cabin heating.

Q3: Does speed affect miles/kWh?
A: Yes, efficiency drops significantly above 65 mph due to increased air resistance.

Q4: How can I improve my miles/kWh?
A: Use regenerative braking, avoid rapid acceleration, maintain proper tire pressure, and reduce high-speed driving.

Q5: How does this compare to MPGe?
A: MPGe includes charging losses, while miles/kWh measures only the energy used while driving.
