  • Publication number: 20200152946
    Abstract: This disclosure details electrical modules that include integrated bus bar locating and separating features. An exemplary electrical module may include a first housing, a second housing, and a bus bar coupon. The first housing, the second housing, or both may include one or more locating and separating features. The bus bar coupon may be automatically separated into a plurality of individual bus bars by the separating features as the first and second housings of the electrical module are moved together. The electrical module could be utilized within electrified vehicle battery packs or various other electrified components.

  • Publication number: 20200124671
    Abstract: A contactor assembly including a housing, an accessible contactor assembly component, a contact bar, and a module is provided. The accessible contactor assembly component may be disposed within the housing. The contact bar may be electrically connected to the accessible contactor assembly component and translatable between an open and a closed position. The module may be programmed to identify whether the contact bar is in the open or closed position based on detected voltage of the accessible contactor assembly component. The assembly may further include a pair of coil terminals, a pair of power terminals, and a diagnostic terminal arranged for electrical communication with the accessible contactor assembly component. The module may be further programmed to detect whether the contact bar is in the open or closed position responsive to detection of a voltage status of the diagnostic terminal.

  • Publication number: 20200079222
    Abstract: A system for a vehicle includes a controller and contactor arranged to close responsive to current magnitude through a coil thereof exceeding a first threshold. The controller, following a request to open the contactor, applies current to the coil at a magnitude less than the first threshold for a duration, and responsive to peak current through the contactor during the duration being less than a second threshold, prevents start of the vehicle.

  • Patent number: 10549643
    Abstract: A vehicle system includes a relay and coil of a contactor. The relay is configured to transfer current between a traction battery and an electrical load when closed. The system also includes a controller configured to operate a switch such that current flow from the traction battery through the coil and switch, and bypassing the relay, causes the relay to close to permit pre-charging of the load.

  • Patent number: 10534030
    Abstract: A power system for a vehicle includes a traction battery that provides power to drive the vehicle, a load, and a harness having wires electrically connecting the traction battery and load, and shielding covering the wires. The power system further includes one or more control blocks that drive a signal onto the shielding, and responsive to an absence of detecting feedback from the signal, issue an interlock integrity alert.

  • Patent number: 10476262
    Abstract: A power control system for a vehicle includes a precharge circuit that is configured to selectively couple a resistor across either a main or return contactor that are configured to selectively couple terminals of a battery to a load bus. The power control system includes a controller programmed to, in response to a precharge request in a presence of the main contactor being closed when commanded to open and the return contactor being open, couple the resistor across the return contactor to precharge the load bus.

  • Patent number: 10384627
    Abstract: A vehicle system includes a contactor including a coil and relay, a traction battery, a load, and a controller configured to transfer current from the traction battery through the coil to pre-charge the load without causing the relay to close such that a voltage drop across the relay falls below a threshold value, and subsequently cause the relay to close.

  • Patent number: 10377247
    Abstract: A charging system for a high voltage battery includes a pair of contactors each electrically connected to one of positive and negative terminals of the battery and configured to enable charging of the battery when closed; and a controller programmed to generate a notification indicating that one of the contactors is welded closed based on port voltage values achieved while issuing a predetermined sequence of open and close commands to the contactors after charge completion.

  • Patent number: 10252635
    Abstract: A high-voltage interlock system includes a first module including a contactor and a shunt connection, and a second module, having first and second circuits, coupled with the first module via first and second wires. The second module, in response to impedance of the shunt connection exceeding a threshold, inhibits a signal to engage the contactor. The impedance is measured across the first and second wires while the first wire is multiplexed with low-voltage power to energize a coil of the contactor, and the second circuit is multiplexed with the signal to engage the contactor.

  • Patent number: 9660379
    Abstract: An exemplary vehicle connector assembly includes, among other things, a first housing, and a second housing configured to selectively engage the first housing in a first position to accommodate a first take-out location. The first housing is further configured to engage the second housing in a second position to accommodate a second take-out location different than the first take-out location. An exemplary electrical connection method includes, among other things, securing a first housing of a connector to a second housing in a first position to accommodate a first take-out location.
