Battery and battery charger systems must be designed for the purpose intended and to meet the requirements of all applicable standards. The primary role of the substation battery system is current handling capability during discharge. Small applications, such as a 50 amp hour substation battery are frequently interconnected with AWG #6 wiring.
Under normal operation, the battery charger supplies dc power to recover the battery voltage after a discharge and to maintain the float voltage while supporting any self-discharge losses in the

This document discusses the components and typical configurations of DC auxiliary power supply systems used in electrical substations. It describes how these systems usually operate at 110V or 220V, and use batteries, chargers, and distribution switchboards. For critical protection, control and interlocking circuits, duplicate battery and charger systems may be installed for reliability.
This same approach can be as readily applied to industrial buildings. To simplify the stock of spares and to ensure ready interchangeability between gear in different substations, as much standard equipment as possible should be used, even at the expense of varying from the ideal installation general, substations should be limited to a capacity of about 2000 or 3000

The Battery''s Purpose Saft Battery 9 Sizing – Batteries provide DC power to the switchgear equipment during an outage. – Best practice is to have individual batteries for each load/application. – Duration of backup is dependent on the battery Ah capacity – Battery loads include: • Trip Current • Close Current
Electrolyte: Stationary batteries of UPS and Power plant back up works on low specific gravity (1.200) electrolyte and larger in volume. This results in less corrosion of grids and longer life. The larger volume keeps the battery comparatively cooler which also adds to life.
Power substation can have one or several DC systems. Factors affecting the number of systems are the need of more than one voltage level and the need of duplicating systems. Today, normal DC auxiliary supply systems in power substation are operating either on the 110 V or 220 V level, though lower levels exist. Some systems at the substation
•The substation batteries for the DC system must be in operation 24/7 – 365 – NOT just for backup power, but also to provide the current needed for day-to-day switching operations •Charger provides current for the load & a float current to charge the battery •Charger alone DO NOT provide enough current if the load exceeds the charger
The term battery system replaces the term battery to allow for the fact that the battery system could include the energy storage plus other associated components. For example, some lithium ion batteries are provided with integral battery management systems while flow type batteries are provided with pumping systems.

The battery is required to supply the DC electrical requirements of the substation, including SCADA, control, protection indication, communications and circuit breaker switching operations when there is no output from the battery charger. This may be due to a loss of AC supply to the substation or a fault in the battery charger.
The higher (more important) role the substation plays from the complete distribution or transmission network point of view, the higher are the demands for the substation's DC auxiliary power systems. To meet the increased demands for reliability and availability, the DC system can be doubled (Figure 3).
