Abstract: A heat exchanger and a method of making same that includes a central polymer core plate laminated on each side with a composite skin. The composite skin includes an electrically insulating outer layer, a middle metal layer to improve thermal conductivity and reduce diffusivity, and an inner layer that will thermally bond to the polymer core plate. A roll to roll method of making the heat exchanger is provided.

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.

CPC classification number: B23K9/08 , B23K9/007 , B23K37/0426
Abstract: A system for joining at least two components by welding includes a magnetic base for receiving the components for welding and a flexible magnetic member configurable to correspond to a weld path defining a weld joining the components. The flexible magnetic member exerts a retention force on the components in response to a magnetic field produced by selective activation of the magnetic base. The system can include a magnetic locating element positioned adjacent a perimeter edge of the component to be welded, for generating a repulsive magnetic force between the flexible magnetic member and the magnetic locating element to locate the flexible magnetic member relative to the perimeter edge and provide clearance for a welding device to access a continuous weld path defined by the perimeter edge, such that the welding device can form a continuous weld along the weld path. A welding method using the system is provided.

Abstract: A battery module includes a plurality of battery cells and a flexible bus. Each of the battery cells has a main body, a first terminal disposed on the main body, and a second terminal disposed on the main body. The main body includes active material configured to generate power from an electrochemical reaction. The bus includes an electrical current harness configured to conduct an electrical current through the battery module and a battery management system configured to detect and transmit status information, as well as selectively control a charging and a discharging of at least one of the battery cells.
