SYSTEMS AND METHODS FOR BATTERY VENTILATION

An electrical storage system includes an electric storage zone (103), an electric storage (102) positioned within the electric storage zone (103), a cooling fluid source (112) in fluid communication with the electric storage zone (103) via a fluid flow path, a modulating valve (118) in the fluid flow path downstream from the cooling fluid source (112) and upstream from the electric storage zone (103), and a detector (120) in fluid communication with the electric storage zone (103). A method for operating an electrical storage system includes adjusting a modulating valve (118) in a fluid flow path to reduce a cooling airflow to an electric storage zone (103), operating a detector (120) in fluid communication with the electric storage zone (103) configured and adapted to sense at least one of smoke, gas, or other particulates during a detection period with a detection system, and adjusting the modulating valve (118) to increase the cooling airflow to the electric storage zone (103).
