1. What is Motor Running Cost?

The motor running cost calculates the electricity cost of operating an electric car motor based on its power consumption, operating time, and local electricity rates. This helps estimate operational expenses for electric vehicles.

2. How Does the Calculator Work?

The calculator uses the following equation:

Where:

• \( P \) — Motor power in watts
• \( t \) — Running time in hours
• \( Rate \) — Electricity cost per kilowatt-hour
• 1000 — Conversion factor from watts to kilowatts

Explanation: The formula converts power consumption from watts to kilowatts and multiplies by time and rate to get total cost.

3. Importance of Calculating Running Cost

Details: Understanding running costs helps in budgeting for electric vehicle operation, comparing costs with gasoline vehicles, and optimizing driving patterns for efficiency.

4. Using the Calculator

Tips: Enter motor power in watts (check vehicle specifications), running time in hours, and your local electricity rate. All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How accurate is this calculation?
A: It provides a basic estimate. Actual costs may vary based on driving conditions, motor efficiency, and battery charging losses.

Q2: Where can I find my motor's power rating?
A: Check your vehicle's specifications manual or manufacturer website for motor power details.

Q3: Does this include charging efficiency losses?
A: No, this is a simplified calculation. For more accuracy, multiply result by 1.1-1.2 to account for charging losses.

Q4: How does this compare to gasoline costs?
A: Electric motors are typically more efficient. To compare, calculate gasoline cost as (miles driven / miles per gallon) × gas price.

Q5: Can I use this for hybrid vehicles?
A: This only calculates the electric portion. For hybrids, you'd need to combine with gasoline cost calculations.
