摘要： 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.

摘要： 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.

摘要： 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.

摘要： An electrified powertrain system for a vehicle includes an electric machine coupled to a driveline. An inverter controller communicates directly with an auxiliary power module. An ignition module indicates either a key-on state or a key-off state. When the ignition module is in a key-off state, a low-power DC/DC converter generates an output voltage originating on the high-voltage DC bus having a magnitude sufficient to activate the inverter controller. The inverter controller detects a key-off uncontrolled generator (UCG) mode. The inverter controller directly communicates detection of the key-off UCG mode to the auxiliary power module. The inverter controller controls the inverter. The auxiliary power module supplies electric power to operate low-voltage electrically-powered powertrain actuators.
