BATTERY SYSTEM WITH INTEGRATED COOLING MANIFOLD

The present disclosure refers to a battery system (100) a plurality of accommodation chambers (26) disposed on top each other in a housing (20) with a plurality of side portions (21, 22, 23), wherein each accommodation chamber (26) includes a plurality of battery cells (29) and a cooling plate (28). A cooling manifold (30) is provided inside the housing (20) and including a vertically extending portion (32) which vertically extends along a side portion (21, ..., 23) of the housing (20), wherein the cooling manifold (30) is connected to each of the plurality of cooling plates (28). The battery system (100) further includes a leakage protection member (40) enclosing at least a portion of the cooling manifold (30), wherein the leakage protection member (40) extends toward a bottom portion (24) of the housing (20) along the cooling manifold (30) such that coolant that is leaked from the cooling manifold (30) is drained toward the bottom portion (24) of the housing (20). Further, a detection unit (50) includes at least one leakage sensor (60) positioned at the bottom portion (24) of the housing (20) and configured to detect coolant drained toward the bottom portion (24) by the leakage protection member (40).
