The trace can be electrically coupled to the circuit. The trace can contact each of the cells to measure voltage of the cells. At least one aspect is directed to a method. The method can include providing a battery system comprising a plurality of cells arranged in an array and a harness.

Abstract: A battery module may include features to support and protect components thereof from external stress and from certain electrical conditions. In particular, a battery module can be provided with components that direct forces away from electrical connection regions, such as at terminals of a battery cell. Such forces can be directed toward other structures that do not define electrical connection regions. A battery module can also be provided with features, such as a series busbar that electrically connects sets of battery cells, that enhance protections from certain electrical conditions. An assembly for such a battery module can provide guidance to align and secure assembled components and to retain them with a potting material during assembly.

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.
