battery array
A battery bank or battery array is an arrangement of many rechargeable batteries connected in series or parallel. Such arrays are also called battery blocks.
Battery banks are used in UPS systems for uninterruptible power supply ofdata centers, hospitals, airports or in public authorities and stadiums. In addition, smaller battery arrays are used in electric vehicles and also as quarter storage in smart grids, where they buffer excess energy. Battery arrays have a high battery capacity due to their arrangement, which can be many thousands of ampere hours( Ah) depending on the area of use and application.
Used in photovoltaic systems, battery banks store excess power and release it when needed. Capacitor banks are an alternative to battery banks.
