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.
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.
