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: An electrical system as described herein is suitable for use in an electric or hybrid vehicle. The electrical system includes electrical devices, such as power transistors, coupled to an electrically and thermally conductive bus bar. The respective nodes of the electrical devices are coupled to the bus bar such that the bus bar carries a combined signal generated by the electrical devices. The bus bar is also thermally coupled to a conduction heat transfer system, such as a liquid cooled cold plate. Thus, the bus bar functions as both an electrical conduit and a conduction-based heat sink for the electrical system.

Abstract: A filter assembly is provided which includes a Faraday cage interface. Electrical noise is filtered by the Faraday cage interface. The Faraday cage interface is configured to prevent passage of electromagnetic waves.

Abstract: A low noise interconnection system is provided which is configured to couple a motor to an inverter. The system comprises a bus bar and a motor winding. The bus bar is configured to receive a current from the inverter. The motor winding is directly connected to the bus bar and configured to receive the current.

Abstract: A high current interconnection system is provided which can be configured to couple a motor to an inverter. A high current interconnection system comprises a bus bar, a motor winding coupled to the bus bar, and a thermal interface. The motor winding is configured to receive a current. The thermal interface can be coupled to at least one of the motor winding or the bus bar. The thermal interface is configured to reduce a temperature of the motor winding or bus bar which the thermal interface is coupled to.
