Abstract: A welding assembly includes a sonotrode, cleaning station, and controller. The controller periodically commands clamping of the sonotrode onto the cleaning block, and a transmission of ultrasonic energy into the cleaning block for a calibrated duration sufficient for removing residual amounts of metal from welding pads of the sonotrode. The cleaning block may include an aluminum bar coated with a polymeric material, e.g., porous polyethylene silica or alumina composite. A thin sacrificial layer of an anti-adhesion material, e.g., colloidal silica, may be periodically applied to the welding pads, particularly after a transition from welding a first metal to welding a second metal. The sacrificial layer may be applied via a sponge, a saturated surface, or spraying.

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.
