Lead-acid batteries stored in the charging room may produce excessive hydrogen due to overcharging, which poses a high risk of hydrogen explosions. A reasonable ventilation design can prevent fire and explosion hazards. To optimize the vent configuration for the charging room, a physical model of the room under various ventilation modes was established. A numerical
