1. What is the Battery Flow Rate?

The Battery Flow Rate (current) is calculated by dividing the power consumption of a load by the voltage of the battery. This tells you how much current is being drawn from the battery.

2. How Does the Calculator Work?

The calculator uses the flow rate equation:

Where:

• \( Power \) — Load power in Watts (W)
• \( Voltage \) — Battery voltage in Volts (V)

Explanation: The equation calculates the current (in Amperes) flowing from the battery to the load based on the power consumption and battery voltage.

3. Importance of Flow Rate Calculation

Details: Knowing the current draw is essential for proper battery sizing, determining battery life, and ensuring your wiring and components can handle the current.

4. Using the Calculator

Tips: Enter the power consumption of your load in Watts and the battery voltage in Volts. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What if my power is in kW?
A: Convert kW to W by multiplying by 1000 (1 kW = 1000 W) before entering the value.

Q2: Does this account for efficiency losses?
A: No, this calculates theoretical current. Real-world systems may draw more current due to inefficiencies.

Q3: Can I use this for AC systems?
A: This calculation is for DC systems. For AC, you need to consider power factor.

Q4: What's a typical flow rate for household batteries?
A: It varies widely. A small 5W device on 12V draws about 0.42A, while a 100W device would draw 8.33A.

Q5: How does this relate to battery capacity?
A: Battery capacity (Ah) divided by current (A) gives approximate runtime in hours.
