Electric forklifts are widely applied in modern warehousing, manufacturing and logistics scenarios, and standardized battery charging management is a core link to ensure long-term stable and safe operation of equipment. Ventilation is the top priority of forklift battery charging management, which directly relates to on-site personnel safety and property security.

First, it is necessary to clarify the core logic of implementing ventilation requirements. For lead-acid batteries commonly used in traditional electric forklifts, hydrogen and a small amount of oxygen will be precipitated during the normal charging process. If the gas accumulates in a closed space to reach a certain concentration, it will bring potential combustion and explosion risks. Even for mainstream lithium batteries used in new energy electric forklifts, abnormal working conditions during charging may also release trace harmful gases, and reasonable ventilation can effectively reduce the concentration of all harmful substances below the national safety threshold.

Then, we introduce the clear implementation rules for ventilation requirements. For the natural ventilation charging area arranged in an open outdoor or semi-open space, the area shall not be lower than 3 square meters for each single charging position, and at least two unobstructed air inlets and outlets facing the outdoor environment shall be reserved, to ensure that the rising light gas can be discharged out of the space in time. For the closed indoor special charging room, it is necessary to configure a special mechanical forced exhaust system, the exhaust outlet shall be set at a position 20cm to 30cm below the top of the charging room, to discharge the hydrogen gathered in the upper space preferentially, and the system shall ensure that the air exchange volume of the entire space reaches more than 6 times per hour. It is not allowed to stack any sundries, pallets or other goods within 1 meter around the exhaust inlet and outlet, to avoid blocking the normal flow of air.

In the daily operation process, relevant personnel shall check the operation state of the ventilation system before each charging process, and keep the ventilation equipment running continuously throughout the whole charging cycle. The gas concentration in the charging area shall be tested regularly every week, and once the concentration of flammable gas exceeds 0.8%, the charging operation shall be stopped immediately, and the site shall be ventilated for more than 30 minutes before troubleshooting.
