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.

Drawing use: SLD / Schematic
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.

PCS

Symbols

Power converter / inverter

A power converter changes electrical power between the circuit forms specified for its application. In a battery energy storage system, a power conversion system commonly provides the interface between DC storage and an AC system. Direction of power flow and operating capabilities are product-specific.

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

A distinction that matters

Inverter, converter and PCS can denote different equipment boundaries. Define what is included in the represented assembly.
