Abstract:
1. A battery pack for a battery system comprising: a battery assembly including a plurality of battery units having a plurality of fluid channels formed therebetween for receiving a fluid therein; and a cooling system coupled to the battery assembly, the cooling system including a tapered first conduit having an inlet for receiving the fluid therein, the first conduit having a width extending along a first width in a width direction of the battery assembly, wherein the width direction is a direction crossing the fluid direction of the first conduit, a second conduit for receiving the fluid therein having a width corresponding to the first width defined by a first side wall and a second side wall, the second conduit having a first end proximate the inlet of the first conduit and a first outlet, and at least one secondary conduit coupled to the second conduit for receiving the fluid therein having a secondary outlet, the at least one secondary conduit defined by one of the first side wall or the second side wall and further defined by an outer wall, a lower wall, and an upper wall, the at least one secondary conduit extends beyond the first width of the battery assembly in the width direction, the second conduit in fluid communication with the first conduit through the plurality of fluid channels of the battery assembly and the second conduit including at least one aperture formed through the first or second side wall that defines the at least one secondary conduit to facilitate fluid communication between the second conduit and the at least one secondary conduit, the at least one aperture positioned proximate the first end of the second conduit to increase a flow rate of the fluid from the inlet of the first conduit through at least one of the fluid channels located proximate the inlet of the first conduit, and a combined cross-sectional area of the first outlet and the secondary outlet is greater than a cross-sectional area of the inlet to facilitate increased flow rate of the fluid, wherein the fluid absorbs heat from the battery assembly.
