Abstract
A battery system is disclosed. The system may include a frame surrounding a battery active region and defining a vent carried by the frame and mounted between the battery active region and coolant passage. The vent may be configured to vent gas from the battery active region to the coolant passage responsive to a pressure or temperature of the gas exceeding a predetermined threshold, and to isolate the battery active region from the coolant passage otherwise.
