Lead acid batteries shall be located in rooms with outside air exchange or in well-ventilated rooms, arranged in a way that prevents the escape of fumes, gases, or electrolyte spray into other areas. Ventilation shall be provided to ensure diffusion of the gases from the battery and prevent the accumulation of an explosive mixture.
Vented lead acid batteries do not always require a separate, dedicated battery room when installed in medium voltage main substation buildings and unit substations, electrical equipment rooms, and control system rack rooms. However, the battery room and installation must comply with SES E14-S02, IEEE 484, NFPA 70, and OSHA 29 CFR.
It is common knowledge that lead-acid batteries release hydrogen gas that can be potentially explosive. The battery rooms must be adequately ventilated to prohibit the build-up of hydrogen gas. During normal operations, off gassing of the batteries is relatively small.
Although alternative energy storage technologies such as fuel cells, flywheels, lithium ion, and nickel cadmium batteries are being explored (see White Paper 65, Comparing Data Center Batteries, Flywheels, and Ultracapacitors for more details) data center and network room UPS systems almost exclu-sively utilize lead-acid batteries.
This article does not cover maintenance free or computer room type batteries and battery cabinets in its Battery Room Design Requirements. The main keywords for this article are vented lead acid batteries, battery room safety requirements, Battery Room Ventilation, and unit substations electrical. Batteries can be hazardous to both personnel and equipment.
Lead-acid batteries are the most widely used energy reserve for providing direct current (DC) electricity, primarily for uninterrupted power supply (UPS) equipment and emergency power system (inverters). There are two basic cell types: Vented and Recombinant Valve Regulated Lead-acid (VRLA) Batteries.
