Charging and Discharging Definition: Charging is the process of restoring a battery’s energy by reversing the discharge reactions, while discharging is the release of stored energy through chemical reactions. Oxidation Reaction: Oxidation happens at the anode, where the material loses electrons.
A battery energy storage system (BESS) is an electrochemical device that charges (or collects energy) from the grid or a power plant and then discharges that energy at a later time to provide electricity or other grid services when needed.
A battery for the purposes of this explanation will be a device that can store energy in a chemical form and convert that stored chemical energy into electrical energy when needed. These are the most common batteries, the ones with the familiar cylindrical shape.
charge Q is stored. So the system converts the electric energy into the stored chemical energy in charging process. through the external circuit. The system converts the stored chemical energy into electric energy in discharging process. Fig1. Schematic illustration of typical electrochemical energy storage system
Batteries and similar devices accept, store, and release electricity on demand. Batteries use chemistry, in the form of chemical potential, to store energy, just like many other everyday energy sources. For example, logs and oxygen both store energy in their chemical bonds until burning converts some of that chemical energy to heat.
