Abstract: A sensing circuit, a vehicular battery pack using a sensing circuit, a method of protecting a circuit with a fuse and a method of providing battery power to a vehicle. The sensing circuit includes the fuse, which is made up of a main element and a sensing element such that the sensing element defines a pre-open detection capability through at least one of a dissimilar geometric profile or a different material choice from that of the main element. The sensing circuit also includes an electrical connector between one or more battery cells and an electronic control module so that the circuit provides indicia of the fusing event. In this way, a fuse opening event takes place in the sensing element prior to the main element in such a way as to give the operator of a battery-powered vehicle advance warning of an impending opening of the main element and consequent electrical circuit shutdown, thereby allowing the operator of the vehicle to take corrective measures as a way to avoid fuse opening and a related loss of vehicular propulsive power.

Abstract: An audio entertainment system for a vehicle includes a primary audio entertainment source to play a primary audio program and a secondary audio entertainment source to play a secondary audio program. The system has a plurality of front speakers, a left rear speaker, and a right rear speaker. A headphone set is for private listening by a rear seat passenger to the secondary audio program. The headphone set is selectably connectable to the secondary audio entertainment source. The system has a normal mode and a selectable enhanced rear seat entertainment mode. In the enhanced mode, an output sound power frequency spectrum of the rear speakers is automatically adjustable by frequency band to reduce audible interference between the primary program and the secondary program as audibly detected by the rear seat passenger while minimizing a disturbance to the primary audio program audibly detectable at the front seat row.

Abstract: A method of controlling an automatic transmission connected to an engine in a motor vehicle includes receiving an input signal generated via an application of force by a switch inside the vehicle. The switch has a predetermined travel and is configured to request a transmission speed-ratio change via an output signal indicative of the received input signal. The output signal is received via a controller programmed with a permitted engine speed range. The transmission is commanded to execute a change from a currently selected speed-ratio to another speed-ratio if the requested speed-ratio change would generate an engine speed within the permitted engine speed range. The switch is commanded to execute full travel under the application of force if the speed-ratio change in the transmission was commanded. Alternatively, the switch is commanded to execute partial travel under the application of force if the speed-ratio change in the transmission was not commanded.

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: A method and system for controlling one or more contactors of a rechargeable energy storage system (RESS) includes adjusting, via a controller, the respective actuating power provided to a respective one or more of the contactors, where adjusting of the actuating power is defined by the energized or non-energized condition of the vehicle and at least one parameter affecting holding and opening forces exerted on the respective contactor. In an example, the controller is configured to use feed forward factors defined by the at least one parameter and to adjust the dynamic actuating current by modulating the dynamic actuating current at a pulse width modulation (PWM) frequency defined by a feed forward window. The system may be configured as a plug-in electric vehicle including the rechargeable energy storage system and the controller.

Abstract: An active isolation detection method may be used with an electrical system having a battery pack connected to a high-voltage bus. The bus has positive and negative bus rails, each having a respective rail-to-ground voltage. The method may include connecting variable resistance element to the high-voltage bus, and determining input information indicative electrical characteristics of the battery pack, the high-voltage bus, and/or a charging station. The method includes varying a bias resistance of the high-voltage bus, via control of the variable resistance element, e.g., via duty cycle control of a binary switch in series with a bias resistor, to produce a varied bias resistance based on the input information. A target voltage shift is achieved on the high-voltage bus as a target level of change in one of the rail-to-ground voltages. An isolation resistance of the electrical system is determined via the controller using the varied bias resistance.

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.

Abstract: An electrical system includes a voltage bus, voltage sensor(s) measuring a first voltage between a positive bus rail and electrical ground, and a second voltage between a negative bus rail and electrical ground, a bias resistor, and a controller. When the switch is closed, the controller measures four or more discrete voltage samples of the first and second voltages. The samples are grouped into first and second sample groups each having three discrete voltage samples, with the second and third voltage samples of the first group being the first and second samples of the second group. The controller estimates a steady-state voltage of the first and second voltages using the sample groups, prior to the first and second voltages converging on actual steady-state voltage values. The controller executes a corresponding control action when the steady-state voltage estimate is stable or unstable relative to a defined stability threshold.

Abstract: An electrical system includes a high-voltage bus connected to a rechargeable energy storage system (RESS) and a high-voltage component connected to the RESS via the voltage bus. The component defines a service opening spanned by a removable cover. The electrical system may include a fastener connecting the cover to the component, as well as a battery disconnect unit (BDU) having a high-voltage switch device connecting the RESS to the high-voltage bus. The switch device closes responsive to a low-voltage drive current to connect the RESS to the high-voltage bus. A drive circuit conducts the current to the switch device. An electrical connector has multiple connector pieces collectively forming a switch in the drive circuit. Disconnection of the pieces from each other opens the switch to interrupt the drive current and cause the high-voltage switch device to open, which disconnects the RESS from the high-voltage bus.
