Centre-tapped battery bank

A centre-tapped battery bank brings out a connection at the middle of the series chain, giving positive and negative rails referred to that point. It is used in some UPS rectifier-inverter designs, three-level converters and telecom or substation DC systems that need a symmetric supply or a defined midpoint for earth-fault detection.

Drawing use: SLD / Schematic
Application: Microgrid systems
Reference family: IEC / IEEE / ANSI

A distinction that matters

A centre-tapped bank has a usable midpoint; an ordinary battery string presents only positive and negative terminals.

Battery

A battery representation identifies an electrochemical source or energy-storage element. The generic depiction can suggest cells or polarity, but it does not determine the number of cells, chemistry, voltage, energy capacity or protective equipment in the selected system.

Application: Microgrid systems
Reference family: IEC / IEEE / ANSI

A distinction that matters

A battery is a storage element. A BESS includes additional equipment and controls; the terms do not identify identical scope.
