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 electric drive-unit encased in a housing includes an electric motor, a first output member, and a second output member. The drive-unit also includes first, second, and third planetary gear-sets, each having first, second, and third nodes. The first gear-set has one node connected to the electric motor. The second gear-set has one node connected to the first planetary gear-set, another node connected to the first output member, and the remaining node fixed to the housing. The third gear-set has one node connected to the first gear-set and another node connected to the second output member. The drive-unit additionally includes a first torque-transmitting device configured to selectively connect one third gear-set node to the housing to thereby affect a first speed-ratio. Furthermore, the drive-unit includes a second torque-transmitting device configured to selectively connect one first gear-set node to one of the third gear-set nodes to thereby affect a second speed-ratio.

摘要： A method of prioritizing power output of first and second power-sources in a vehicle includes identifying, via a controller communicating with a satellite, the vehicle's position on a specific road course. The method also includes receiving a request for total amount of power from both power-sources and determining first power-source power and available second power-source target maximum power based on the vehicle position. The method also includes determining, based on the vehicle position, a minimum energy reserve of a source configured to energize the second power-source and available second power-source power based on the determined reserve. The method also includes subtracting the first power-source power from the requested total amount of power to determine a requested second power-source power. Furthermore, the method includes comparing the available and the requested second power-source power and generating the smaller power value to minimize the time for the vehicle to traverse the road course.

摘要： A hybrid powertrain for propelling a vehicle includes an engine and an energy storage system operatively connected to the engine. Both the engine and the energy storage system are operable for providing power to propel the vehicle. A control system is operatively connected to the engine and the energy storage system and is configured to execute a stored algorithm that determines required energy reserve, remaining energy, and power capability of the energy storage system. The control system commands operation in one of a first operating mode, a second operating mode, and a third operating mode based on the required energy reserve, the remaining energy, and the power capability of the energy storage system.

摘要： A differential drive system includes an electric motor for generating an electric motor torque and an input planetary gear-set operatively connected to the electric motor to receive the electric motor torque. The input planetary gear-set has first, second, and third members. The first member receives the electric motor torque, the second member provides a first input torque in a first rotational direction in response to the electric motor torque, and the third member provides a second input torque in a second rotational direction, opposite the first direction, in response to the electric motor torque. The system also includes a first output gear-set operatively connected to the input planetary gear-set, and providing a first output torque in response to the first input torque. The system additionally includes a second output gear-set operatively connected to the input planetary gear-set and providing a second output torque in response to the second input torque.

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 electrical system includes cables, a DC charge connector, first and second battery modules, a splice device, and a controller. Each battery module has first, second, third, and fourth electrical connectors receiving a respective one of the cables. The battery modules are connected to each other via the cables, and further have first, second, third, and fourth switches that connect battery cell strings to one or more connectors. The charge connector is connected to one of the cables between the first electrical connectors. The splice device connects the charge connector to the first connector of the first battery module and to a pair of the cables. A charging current may be split between the battery modules. The controller selectively establishes parallel charging, parallel drive, and separate drive and charging modes for each battery module. The system may have an independent drive mode.

摘要： A DC charging circuit has a pair of switches and a battery pack with a maximum voltage capacity, and a power inverter module (PIM). The pair of switches connects/disconnects the battery pack to/from the PIM. An electric machine has phase windings sharing a motor neutral terminal. The phase windings are electrically connected to respective switching pair of the PIM. A switching module has one or two additional switches selectively connecting the PIM to the station, and a center switch selectively connecting the station to the motor neutral terminal. A controller executes a method that establishes a boost mode of the PIM when the maximum voltage capacity exceeds the maximum charging voltage. The boost mode is established by closing the pair of switches of the RESS, closing the center switch of the switching module and one of the additional switches, and opening the other additional switch if present.

摘要： A transmission includes an input member, an output member, a first electric device, and a second electric device. A first planetary gear set is coupled to the first electric device. A second planetary gear set is coupled to the second electric device. The output is coupled to both the first planetary gear set and the second planetary gear set. The input is connected to the first planetary gear set. A fixed ratio gear reduction system couples the input and the second planetary gear set. The fixed ratio gear reduction system is operable to transmit rotation from the input to the second planetary gear set at a reduced rotational speed and at an increased torque.
