1. What is E-Bike Watt-Hours Calculation?

The watt-hour (Wh) calculation for electric bike batteries determines the energy capacity needed based on the bike's power consumption and desired range. It's crucial for selecting the right battery size.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Power \) — Bike's power consumption in watts (W)
• \( Time \) — Desired riding time in hours (h)

Explanation: Multiplying power by time gives the energy capacity needed in watt-hours (Wh), which is the standard unit for battery capacity.

3. Importance of Watt-Hours Calculation

Details: Proper battery sizing ensures your e-bike has enough range for your needs without carrying unnecessary weight. It helps compare different battery options accurately.

4. Using the Calculator

Tips: Enter your bike's typical power consumption in watts and your desired riding time in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: How do I find my bike's power consumption?
A: Check your bike's specifications or motor rating. Typical e-bikes range from 250W to 750W.

Q2: What's a typical watt-hour capacity for e-bike batteries?
A: Common sizes range from 300Wh to 700Wh for most commuter bikes, with high-performance models going up to 1000Wh.

Q3: How does this relate to battery amp-hours (Ah)?
A: To convert Wh to Ah, divide by battery voltage (e.g., 36V, 48V). Wh = V × Ah.

Q4: Does terrain affect these calculations?
A: Yes, hilly terrain increases power consumption. Consider adding 20-50% to your calculations for hilly areas.

Q5: How accurate is this calculation?
A: It provides a baseline estimate. Actual range may vary based on riding style, terrain, temperature, and battery age.
