Abstract

The present invention relates to a battery system (50) that comprises at least one battery module (20) which is interconnected between a first system terminal (51) and a second system terminal (52) by a plurality of high current connectors (63), and a housing (70) with a plurality of exterior walls (71) that enclose the at least one battery module (20) and the plurality of high current connectors (63) and with at least one partition wall (72) that is arranged within the housing (70). A flow channel loop (73) is formed within the housing (70) by the at least one partition wall (72) and the exterior walls (71), and a gas conveyor (80) that is configured for providing a gas flow circulation (74) through the flow channel loop (73) and at least one gas sensor (81) that is configured for detecting an excess concentration of at least one gas species in the gas flow circulation (74) are arranged in the flow channel loop (73). Preferably, the high current connectors (63) and all battery cells (10) of the battery system (50) form a current path between the first system terminal (51) and the second system terminal (52) and the gas flow circulation (74) follows this current path. Another aspect of the present invention relates to a vehicle comprising the battery system (50) of the invention and another aspect of the invention relates to a method for determining an abnormal condition of a battery system (50).
