Technical FAQs 4

Do vented lead acid batteries need a separate battery room?

Vented lead acid batteries installed in medium voltage main substation buildings and unit substations, electrical equipment rooms and control system rack rooms shall not require a separate, dedicated battery room and shall be in accordance with SES E14-S02. The battery room and installation shall comply with IEEE 484, NFPA 70 and OSHA 29 CFR.

Why do batteries need to be ventilated?

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. However, the concern is elevated during times of heavy recharge or the batteries, which occur immediately following a rapid and deep discharge of the battery.

What happens if you overestimate battery charging capacity?

If you over-estimate the required charging capacity, the charger may deliver too much current. Excessive charging current can cause battery overheating, accelerated water loss in flooded type batteries, and damaged batteries. Many battery manufacturers recommend a maximum charging rate of 20% of the amp hour capacity of the battery.

Are battery charging rooms based on lead traction batteries safe?
