Abstract
A battery system for a motor vehicle or another electrical system includes a battery cover, one or more battery cells, and a diverter assembly. The cells define a battery cavity in fluid communication with a corresponding vent opening. An air gap may be defined in an exhaust volume within the battery system. The diverter assembly includes a diverter body arranged relative to the vent openings. The diverter body is moveable or stationary. In response to a thermal propagation event occurring in the module or at least one of the battery cells, each diverter body diverts a high-temperature flow of ejecta from the cavity into an exhaust volume in a predetermined flow direction when the flow of ejecta passes through the vent opening. The diverter assembly may include a support member connected to the diverter body and connectable to the battery cell.
