1. What is Miles per kWh?

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

2. How Does the Calculator Work?

The calculator uses the simple formula:

\[ \text{Miles per kWh} = \frac{\text{Distance Traveled (miles)}}{\text{Energy Used (kWh)}} \]

Where:

Explanation: This calculation gives you the vehicle's energy efficiency in terms of distance traveled per unit of energy consumed.

3. Importance of Miles per kWh

Details: Knowing your EV's miles per kWh helps you estimate range, compare efficiency between vehicles, calculate charging costs, and understand how driving conditions affect energy consumption.

4. Using the Calculator

Tips: For accurate results, measure distance over a full charge cycle and use the energy consumption reported by your vehicle's systems. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a good miles per kWh value?
A: Most EVs get 3-4 miles/kWh. Higher values indicate better efficiency. Factors like driving style, weather, and terrain affect this number.

Q2: How can I improve my miles per kWh?
A: Drive at moderate speeds, use regenerative braking, minimize rapid acceleration, reduce climate control usage, and keep tires properly inflated.

Q3: Does cold weather affect miles per kWh?
A: Yes, cold temperatures can reduce efficiency by 20-40% due to battery chemistry and increased use of heating systems.

Q4: How does this relate to charging costs?
A: If electricity costs $0.15/kWh and your car gets 4 miles/kWh, you pay about $0.0375 per mile (15÷4).

Q5: Is miles per kWh the same as MPGe?
A: No, MPGe converts kWh to gallons of gasoline equivalent (33.7 kWh = 1 gallon equivalent). Miles per kWh is a direct efficiency measurement.
