1. What is an Electric Car Running Cost Calculator?

Definition: This calculator estimates the cost per kilometer to operate an electric vehicle based on energy consumption, electricity rates, and distance traveled.

Purpose: Helps EV owners understand and compare operating costs with traditional vehicles.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( \text{Cost} \) — Running cost per kilometer ($/km)
• \( E \) — Energy consumption (kWh)
• \( \text{Rate} \) — Electricity cost ($/kWh)
• \( \text{Distance} \) — Distance traveled (km)

Explanation: The total energy cost is divided by distance to determine cost per kilometer.

3. Importance of Running Cost Calculation

Details: Understanding running costs helps with budgeting, comparing vehicle economics, and evaluating charging strategies.

4. Using the Calculator

Tips: Enter energy consumption (kWh), electricity rate (default $0.15/kWh), and distance (km). All values must be > 0.

5. Frequently Asked Questions (FAQ)

Q1: Where do I find my car's energy consumption?
A: Check your vehicle's dashboard display or owner's manual, typically shown as kWh/100km or kWh/km.

Q2: What's a typical electricity rate?
A: Residential rates average $0.10-$0.30/kWh, but vary by location and time-of-use plans.

Q3: Does this include charging efficiency losses?
A: No, for precise calculations, multiply energy by ~1.1 to account for ~90% charging efficiency.

Q4: How does this compare to gasoline costs?
A: EVs typically cost 1/3-1/2 the fuel cost of comparable gasoline vehicles per km.

Q5: Should I use home or public charging rates?
A: For personal cost analysis, use your home rate. For comparison, note public chargers often cost 2-3x home rates.
