A thermal management system for a rechargeable battery pack assembly includes a conduit having an upstream end and a downstream end, the downstream end operatively connectable to an enclosure of the rechargeable battery pack assembly at a port of the rechargeable battery pack assembly. A sealing mechanism is configured to transition from a first state in which the sealing mechanism blocks flow of an applied stream of water through the conduit from the upstream end through the port, to a second state in which the sealing mechanism permits flow from the upstream end to the port and through the port into the interior cavity to cool the interior cavity.

A cell temperature measurement system for a battery module is described. The system may include a cell monitoring unit (CMU) configured to generate temperature measurements for a plurality of battery cells included as part of the battery module according to contactless, optical, or line-of-sight measurements made with one or more sensors associated with a temperature measurement device.

Battery cell group temperature measurement system

A method of leak testing a fluid passage of a part manufactured from a low conductivity material includes measuring an electrical resistance between an interior wall surface of the fluid passage of the part, and an exterior wall surface of the fluid passage of the part. The measured electrical resistance is compared to a threshold value to determine if the measured electrical resistance is equal to or greater than the threshold value, or if the measured electrical resistance is less than the threshold value. The threshold value is equal to a nominal wall thickness of the fluid passage multiplied by a resistivity of the material used to form the part. The part passes the leak test when the measured electrical resistance is equal to or greater than the threshold value. The part fails the leak test when the measured electrical resistance is less than the threshold value.

Each cavity is capable of receiving a battery cell stack comprising a plurality of battery cells and optionally cooling plates and foam pads. Partitions comprise a plurality of polymeric repeating spacers, and each spacer from each partition can correspond to a cooling plate common to a plurality of battery cell stacks. Each of the repeating spacers and cooling plates can include a plurality of aligned apertures, and corresponding bolts can occupy the aligned apertures and secure the same to the endplates. Each repeating spacer can correspond to a complete or partial battery unit, wherein a complete battery unit comprises a first battery cell, a cooling plate, a second battery cell, and a foam pad.

A method of assembling a power module includes placing a first plurality of cells adjacent to one another to form a first cell layer. A flexible circuit layer is positioned above the first cell layer, the flexible circuit being electrically conductive. A second plurality of cells is positioned adjacent to one another to form a second cell layer aligned with the first cell layer such that the flexible circuit layer is sandwiched between the first cell layer and the second cell layer. The flexible circuit layer is folded along each of a plurality of axes of rotation such that each one of the first plurality of cells faces another one of the second plurality of cells. Each of the first plurality of cells and the second plurality of cells has respective first and second tabs (extending from their respective short ends) which are welded to the flexible circuit layer.
