BATTERY PACK VENTING SYSTEM AND VENTING METHOD

A battery pack venting system includes one or more cell stacks of a traction battery pack; and a vent management member having a divider wall that separates an inner channel of the vent management member from an outer channel of the vent management member. The inner channel opens toward the cell stack. The inner channel is configured to communicate a flow of vent byproducts in a first direction to a position where the flow of vent byproducts can move around the divider wall from the inner channel to the outer channel. The outer channel is configured to communicated the flow of vent byproducts in an opposite, second direction to at least one outlet from the vent management member.
