摘要： A vehicle includes a controller that, responsive to data indicating a voltage associated with an inrush current through a main contactor exceeds a first threshold, commands the main contactor to open and inhibits the vehicle from being driven, and responsive to data indicating the voltage exceeds a second threshold less than the first threshold, commands the main contactor to sequentially open and then close.

摘要： 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.

摘要： An example method includes intentionally precharging a powertrain of an electric vehicle for an first time period that is different than a second precharge time period. An example electric vehicle assembly includes a precharge contactor transitionable back and forth between an open state and a closed state, a first main contactor, a second main contactor, and a controller configured to selectively close the second main contactor after the precharge contactor has been closed for a first time period that is different than a second precharge time period.

摘要： This disclosure relates to an electrified vehicle configured to disconnect a battery from a load, and a corresponding method. An example electrified vehicle includes an array of battery cells and an electrical conductor connecting the array to a load. A disconnect is arranged along the electrical conductor. Further, the electrified vehicle includes an electronic circuit with a switch and an igniter. When a voltage drop across the electrical conductor exceeds a threshold, the switch is configured to permit current to flow from at least one of the battery cells through the igniter to trigger the disconnect thereby disconnecting the array of battery cells from the load.

摘要： 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.

摘要： 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.

摘要： 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.
