6 FAQs about [Relationship between energy storage capacity and discharge power]

What is energy storage capacity?

It is usually measured in watts (W). The energy storage capacity of a storage system, E, is the maximum amount of energy that it can store and release. It is often measured in watt-hours (Wh). A bathtub, for example, is a storage system for water. Its “power” would be the maximum rate at which the spigot and drain can let water flow in and out.

How do you calculate energy storage capacity?

Specifically, dividing the capacity by the power tells us the duration, d, of filling or emptying: d = E/P. Thus, a system with an energy storage capacity of 1,000 Wh and power of 100 W will empty or fill in 10 hours, while a storage system with the same capacity but a power of 10,000 W will empty or fill in six minutes.

What is the difference between power and capacity?

A bathtub, for example, is a storage system for water. Its “power” would be the maximum rate at which the spigot and drain can let water flow in and out. Its “capacity” would be the amount of water the tub can hold. Together, the power and the capacity determine how long it will take to fill (charge) or empty (discharge) the energy storage system.

What is the power of a storage system?

The power of a storage system, P, is the rate at which energy flows through it, in or out. It is usually measured in watts (W).
