The battery room is tested in accordance with local as well as international norms and the manufacturer's specifications. It serves to ensure standard-compliant accommodation in protected and, if necessary, closed electrical operating facilities. Possible types of accommodation include rooms, electrical facilities, containers or cabinets. These premises must meet certain safety criteria and special requirements depending on the type and size of the battery. Especially the discharge resistance of the floor, the ventilation of the room, as well as its marking with certain warning signs, must be fulfilled by the customer for the standard-compliant operation of stationary battery systems.
