Energy Storage Calculator

The Formula

The formula for calculating runtime of an energy storage device is:

\[Runtime (hours) = \frac{Energy Capacity (Wh)}{Power Consumption (W)}\]

Where:

• Runtime: The estimated duration the energy storage device can power the load (in hours)
• Energy Capacity: The total energy the storage device can hold (in watt-hours, Wh)
• Power Consumption: The rate at which energy is being consumed (in watts, W)

Calculation Steps

1. Identify the energy capacity (Wh) and power consumption (W)
2. Insert these values into the formula:
3. Runtime = Energy Capacity ÷ Power Consumption
4. Perform the division to get the result in hours

Example Calculation

Let's calculate the runtime for a 100 Wh energy storage device with a power consumption of 20 W:

\[Runtime = \frac{100 Wh}{20 W} = 5 hours\]
