Abstract
This chapter analyzes the safety conditions in battery rooms for renewable energy installations, focusing on sizing, ventilation, and classification according to the ATEX directive. For this purpose, the applicable European regulations are used as a reference to determine the classified areas according to fire and explosion risks, as well as the required safety distance and ventilation. An example application for a 24-V lead-acid battery is presented. The chapter also discusses safety measures for battery rooms that produce hydrogen and oxygen during the charging process, with reference to the technical reference specifications for determining the required hazard distance and ventilation openings. Graphical results are provided for the different battery types and voltages analyzed. Finally, it is concluded that the measures established by the new European application standard need to be adapted to comply with current legislation.
