Battery system configured to detect abnormal battery system conditions and method of the same

Abstract

A battery system includes a battery module, a housing, a gas conveyor, and a gas sensor. The battery module is interconnected between a first system terminal and a second system terminal by a plurality of high current connectors, and the housing includes: a plurality of exterior walls enclosing the battery module and the plurality of high current connectors; and a partition wall within the housing. The gas conveyor is configured to circulate a gas flow through a flow channel loop formed within the housing by the partition wall and the exterior walls, and the gas sensor is arranged in the flow channel loop and is configured to detect an excess concentration of a gas species in the gas flow.
