1. What is the Range Calculation?

The range calculation estimates how far a battery-operated car can travel on a full charge based on its battery capacity and energy consumption rate. This helps drivers plan trips and understand their vehicle's capabilities.

2. How Does the Calculator Work?

The calculator uses the range formula:

Where:

• Battery Capacity — Total energy storage of the vehicle's battery in kilowatt-hours (kWh)
• Consumption — Energy used per kilometer traveled in watt-hours per kilometer (Wh/km)
• 1000 — Conversion factor from kWh to Wh (1 kWh = 1000 Wh)

Explanation: The formula converts battery capacity to watt-hours, then divides by consumption rate to determine how many kilometers can be traveled.

3. Importance of Range Calculation

Details: Accurate range estimation is crucial for trip planning, understanding vehicle efficiency, and comparing different electric vehicle models. It helps prevent range anxiety and ensures safe travel.

4. Using the Calculator

Tips: Enter battery capacity in kWh (typically between 30-100 kWh for modern EVs) and consumption in Wh/km (typically between 150-250 Wh/km for efficient models). All values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: Is this the actual range I'll get?
A: This is the theoretical maximum range. Real-world range may be 10-20% less due to factors like weather, terrain, driving style, and accessory use.

Q2: Where can I find my car's consumption rate?
A: Check your vehicle's dashboard display (often shows average consumption), owner's manual, or manufacturer specifications.

Q3: Does battery degradation affect range?
A: Yes, as batteries age they lose capacity. After several years, you may need to use 80-90% of original capacity in calculations.

Q4: How can I improve my car's range?
A: Drive at moderate speeds, use regenerative braking, minimize AC/heat use, keep tires properly inflated, and reduce unnecessary weight.

Q5: What's a good Wh/km consumption rate?
A: Under 200 Wh/km is excellent, 200-250 is good, and above 250 means shorter range or larger battery needed.
