Turn ON both solid state relays for charge and discharge control. Current flows in both directions. In order to prevent over charging, the solid state relay on the charge control side turns OFF. On the discharge side, current will flow because there is a diode.
When energized (electromechanical) or triggered (static), the relay closes the switch to allow current flow. Normally closed relays are the opposite. When energized (electromechanical) or triggered (static), they open, preventing current flow. Relay switches are shown above in their default “de-energized” position.
Battery Energy Storage System (BESS) is a technology that stores electrical energy in the form of chemical energy within batteries. This stored energy can be later converted back into electricity and released when needed. BESS plays a crucial role in enhancing the reliability, stability, and efficiency of electrical power systems.
