1. What is EV Battery Capacity?

EV battery capacity measures how much energy a battery can store, typically measured in kilowatt-hours (kWh). It determines how far an electric vehicle can travel on a single charge.

2. How Does the Calculator Work?

The calculator uses the simple formula:

Where:

• \( Power \) — Charging power in kilowatts (kW)
• \( Time \) — Charging duration in hours (h)

Explanation: This formula calculates the total energy transferred during charging by multiplying the power level by the charging time.

3. Importance of Capacity Calculation

Details: Knowing battery capacity helps estimate driving range, compare different EV models, and understand charging requirements.

4. Using the Calculator

Tips: Enter the charging power in kW and the charging time in hours. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What's a typical EV battery capacity?
A: Most modern EVs have capacities between 40-100 kWh, with some high-end models exceeding 100 kWh.

Q2: How does capacity relate to range?
A: Generally, 1 kWh provides 3-5 miles of range depending on vehicle efficiency and driving conditions.

Q3: What factors affect actual capacity?
A: Temperature, battery age, charging speed, and battery management systems can all impact usable capacity.

Q4: Is higher capacity always better?
A: While higher capacity means more range, it also means heavier batteries and longer charging times.

Q5: How accurate is this calculation?
A: This provides theoretical maximum capacity. Actual usable capacity is typically about 90-95% of this value.
