6 FAQs about [Principle of energy storage element parameter measurement]
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). 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.
