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 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: A fuse system includes a fuse element configured to receive a current. A controller is operatively connected to the fuse element and has a processor and tangible, non-transitory memory on which is recorded instructions for executing a method for determining a remaining fuse life (LR) of the fuse element. Execution of the instructions by the processor causes the controller to determine a temperature (T) of the fuse element. The fuse system may be part of a vehicle. The controller may be configured to determine if the remaining fuse life is below first and second thresholds. If the remaining fuse life is above the second threshold, a first message may be displayed to a vehicle display. If the remaining fuse life is below the second threshold, the vehicle may be shifted to a predefined alternative operating mode.

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 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: Dynamically monitoring of an electrically-isolated power bus for a DC power system is described, and includes dynamically monitoring voltage and current on the power bus to determine a variation in the voltage on the power bus. When the variation in the voltage on the power bus is less than a threshold, an active positive isolation resistance term and an active negative isolation resistance term are determined. A first voltage balance term is determined based upon a ratio of the active positive isolation resistance term and the active negative isolation resistance term. A dynamic positive isolation resistance term and a dynamic negative isolation resistance term are determined based upon the active negative isolation resistance term. A fault associated with the power bus is determined based upon the dynamic positive isolation resistance term and the dynamic negative isolation resistance term.

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.
