Abstract: A welding block for a welding system secures together first and second components of a workpiece for a motor vehicle to reduce distortion of the first and second components during a welding process. The welding block includes a jig mechanism that has a proximal surface for receiving a load from an arm of the welding system. The jig mechanism further includes a distal surface for engaging the first component and securing the first and second components to one another during the welding process. The jig mechanism defines a passage, such that heat flows from the distal surface to a coolant flowing through the passage. The welding block further includes a sensor coupled to the jig mechanism for detecting a measured variable associated with at least one of the first and second components.

Abstract: A method and a test fixture for evaluating a battery cell are described, wherein the battery cell is composed of a cell body having a plurality of electrode foils that are joined to both a positive terminal and a negative terminal at weld junctions. The method includes retaining the cell body of the battery cell in a first clamping device and gripping one of the positive and negative terminals in a terminal gripper. A dynamic stress end effector coupled to the terminal gripper is employed to apply a vibrational excitation load to the one of the positive and negative terminals. Impedance between the positive terminal and the negative terminal is monitored via a controller, and integrity of the weld junction of the one of the positive and negative terminals is evaluated based upon the impedance.

Abstract: A vehicle-battery system including a battery cell and a micro heat exchanger. The micro heat exchanger includes at least one fluid tube positioned in direct contact with the battery cell. The fluid tube comprises a heat-transfer tube section positioned between a fluid tube entrance and exit and in direct contact with the battery cell. The fluid tube is configured to receive a heat-transfer fluid, such a nanofluid, and channel the heat-transfer fluid through the heat-transfer tube section, to the fluid tube exit. The heat-transfer fluid is configured to cool or heat the battery cell when, in operation of the vehicle-battery system, the heat-transfer fluid is channeled through the heat-transfer tube section. The technology in various embodiments also includes a fluid modification device and a computerized controller for controlling the fluid modification device or other operations of the system such as pumping of the heat-transfer fluid.

Abstract: A method and an apparatus for evaluating a battery cell. The battery cell may include a hermetically sealed outer casing, a plurality of electrically conductive components enclosed within the outer casing, an electrically conductive terminal having a proximal end that extends within the outer casing and a distal end that extends in a longitudinal direction relative to the battery cell outside the outer casing, and a solid electrical and mechanical joint formed between one or more of the electrically conductive components and the proximal end of the electrically conductive terminal. Evaluation of the battery cell may include measuring the impedance of the battery cell while applying a longitudinal pulling force or a transverse bending force to the electrically conductive terminal and the solid electrical and mechanical joint.

Abstract: A mechanically conformable micro-heat exchanger for use in managing temperature of a subject component. The exchanger includes a flexible fluid tube. In various embodiments, the tube is connected to a flexible substrate, such as by a flexible polymer. The exchanger can be changed manually from an initial shape to a first shape to conform to a shape of the subject component. The flexible fluid tube is configured to channel heat-transfer fluid through a heat-transfer tube section of the tube. The heat-transfer fluid is configured to cool or heat the subject component when, in operation of the mechanically conformable micro-heat exchanger, the heat-transfer fluid is channeled through the heat-transfer tube section.

Abstract: A number of variations may involve a method that may include providing a non-conductive layer. A conductive layer may be provided overlying the non-conductive layer with the conductive layer to form a sensor device. An opposition to electrical current through the conductive layer may be monitored. The location of a status of the non-conductive layer or of the conductive layer may be determined through a change in the opposition.

Abstract: A vibration welding system includes vibration welding equipment having a welding horn and anvil, a host machine, a check station, and a welding robot. At least one displacement sensor is positioned with respect to one of the welding equipment and the check station. The robot moves the horn and anvil via an arm to the check station, when a threshold condition is met, i.e., a predetermined amount of time has elapsed or a predetermined number of welds have been completed. The robot moves the horn and anvil to the check station, activates the at least one displacement sensor, at the check station, and determines a status condition of the welding equipment by processing the received signals. The status condition may be one of the alignment of the vibration welding equipment and the wear or degradation of the vibration welding equipment.
