Abstract: An apparatus can include a space between a first battery cell and a second battery cell. The apparatus can include a closure to at least partially surround the space. The space can receive a coolant. The coolant can contact at least a portion of the first battery cell and at least a portion of the second battery cell.

Abstract: A battery pack can include a bay having a first bay wall and a second bay wall. The battery pack can include a battery cell having a top portion and a bottom portion. The top portion of the battery cell can face the first bay wall of the bay and the bottom portion of the battery cell can face a second bay wall of the bay.

Abstract: A cable reel includes a spool to extend and retract a cable that includes a first conductor. The cable reel further includes a first connector that is connected with the spool and rotates in relation to the spool. The first connector includes a first contact that is connected to the first conductor of the cable. The cable reel further includes a second connector that does not rotate. The first connector and the second connector are mateable. The second connector includes a second contact that is connected to a second conductor. The first connector and the second connector automatically mate to make an electrical connection between the first conductor of the cable and the second conductor when the first connector and the second connector are aligned in a predetermined position and at least some length of cable has been extended.

Abstract: A method of manufacturing a shrouded turbine blade is disclosed. In an embodiment, the method comprises casting a shrouded turbine blade including a shrouding. The shrouding includes an abutment face. The method includes welding a coating composed of a different material than the shrouded turbine blade onto the abutment face. The method includes applying hot isostatic pressing to the abutment face after welding the coating. The hot isostatic pressing is sufficient to heal internal defects in the abutment face. The method includes machining the shrouded turbine blade after applying hot isostatic pressing.
