Therefore, we propose the dynamic reconfigurable-battery (DRB) energy storage technology based on energy digitalization. In comparison to the conventional norm of fixed series-parallel connections, the DRB networks use new program-controlled connections between battery cells/modules. By controlling the charging/discharging time of each …

A battery is a device that stores chemical energy and converts it to electrical energy. The chemical reactions in a battery involve the flow of electrons from one material (electrode) to another, through an external circuit. The flow of electrons provides an electric current that can be used to do work. To balance the flow of electrons, charged ...

A flywheel energy storage can have energy fed in the rotational mass of a flywheel, store it as kinetic energy, and release out upon demand. They work by spinning up a heavy disk or rotor to high speeds and then tapping that rotational energy to discharge high power bursts of electricity. It is difficult to use flywheels to store energy for ...
