    Abstract: An electromagnetic interference reduction assembly for a transmission is disclosed. A transmission casing includes a base and walls extending outwardly away from the base to a distal edge. The transmission casing defines a first cavity between the walls and includes a platform disposed between the walls. A power inverter module is disposed in the first cavity and supported by the platform when in the first cavity. The power inverter module generates electrical noise during operation which produces electromagnetic interference. A lid is attached to the distal edge of the walls to contain the power inverter module inside the first cavity. A grounding member engages the power inverter module and the lid when the lid is attached to the transmission casing to electrically connect the power inverter module to the lid to reduce the electrical noise exiting the first cavity which reduces the electromagnetic interference exiting the first cavity.

    Abstract: A multi-pack battery system having at least first and second battery packs each with positive and negative terminals, and each with upper and lower switches respectively connected to the positive and negative terminals. The battery packs have a first voltage level, and are connectable in either series or parallel. A controller controls an ON/OFF state of the switches in response to input signals to select between two series charging modes, three parallel charging modes, and one or more propulsion modes. Some embodiments have a series propulsion mode. An electric powertrain system includes first and second power inverter modules (“PIMs”), an electrical load, front and rear electric machines connected to a respective one of the first and second PIMs, and the battery system. The powertrain system may selectively provide all-wheel, front-wheel, or rear-wheel drive capabilities in each of the various propulsion modes.

    Abstract: An onboard charging module (OBCM), e.g., for a vehicle, is characterized by an absence of a transformer and includes an AC-to-DC voltage rectifier, DC-DC buck converter, DC-DC boost converter, DC link capacitor between the buck converter and boost converter, and solid-state devices. The devices include a diode and first and second switches having opposite open/closed switching states. The first and second switches are connected to a common rail of a DC bus, the first switch and diode are between the voltage rectifier and boost converter, and the second switch is between the link capacitor and buck converter. Third and fourth switches may be used on the opposite rail as the first and second switches. The OBCM is operable, via operation of the solid-state devices, to charge the HV-ESS via an AC power supply while maintaining current isolation. An electrical system includes the OBCM, DC bus, and HV-ESS.

    Abstract: An electric propulsion system for a mobile platform includes a battery system connected to positive and negative bus rails, an accessory load having a rotary electric machine, a traction power inverter module (“TPIM”), and an accessory load, switches configured to transition the battery modules to a series-connected (“S-connected”) configuration during a direct current fast-charging (“DCFC”) operation of the battery system, and a controller. When battery modules of the battery system are connected in series during a direct current fast-charging (“DCFC”) operation, the controller executes a diagnostic method to determine bus rail voltages on the positive and negative bus rails and a mid-bus voltage, identifies a diagnosed electrical condition of the electric propulsion system by comparing the voltages to expected values or ranges, and executes a control action in response to the diagnosed electrical condition.
