According to the National Electrical Code, (NEC) the battery room should be ventilated, as required by NFPA 70 480.10 (A). “Ventilation. Provisions appropriate to the battery technology shall be made for sufficient diffusion and ventilation of gases from the battery — to prevent the accumulation of an explosive mixture.”
Battery room ventilation codes and standards protect workers by limiting the accumulation of hydrogen in the battery room. Hydrogen release is a normal part of the charging process, but trouble arises when the flammable gas becomes concentrated enough to create an explosion risk — which is why safety standards are vitally important.
Title 29 Code of Federal Regulations — Ventilation shall be provided to ensure diffusion of the gases from battery and to prevent accumulation of an explosive mixture. The Institute of Electrical and Electronics Engineers (IEEE) Standards 1188, 450, 484, and 485 provide guides that focus on the battery system design, maintenance, and operation.
Battery Room Ventilation System controlled air would lead to exorbitant electricity costs — also, note that this design fully complies with is designed for detecting hydrogen gas at NFPA 1: Fire Code 52.2.3.8.) low levels and dissipate the gas to prevent accumulation.
Battery rooms shall be designed with an adequate exhaust system which provides for continuous ventilation of the battery room to prohibit the build-up of potentially explosive hydrogen gas. During normal operations, off gassing of the batteries is relatively small.
For standby DC power systems or AC UPS systems, battery room ventilation is calculated in accordance to EN 50272-2 Standard. Battery room ventilation flow rate is calculated using the following formula: Q = v * q * s * n * I gas * Cn / 100 Igas values for stationary lead-acid batteries are (according to EN 50272-2: Stationary Batteries):
