摘要： Disclosed are control algorithms and system architectures for managing wireless vehicle charging, including vehicles with rechargeable battery packs, wireless charging capabilities, and control logic for governing such charging. A method is disclosed for managing charging of an electrical storage unit of a motor vehicle at a wireless vehicle charging station. The method includes: receiving a sensor signal indicating detection of an obstruction within a predetermined proximity of the vehicle charging station; determining whether the detected obstruction is living or lifeless; initiating, via a vehicle controller responsive to the detected obstruction being a living object, a first remedial action strategy that commands the vehicle to generate a visual or audible cue to drive away the living object; and, initiating, via the vehicle controller responsive to the detected obstruction being a lifeless object, a second remedial action strategy that commands the motor vehicle to move and thereby avoid contact with the object.

摘要： An electrical system includes a voltage bus, battery pack, power inverter module (PIM), electric machine, first contactor, and controller. The PIM is connected to the battery pack and has a capacitor, voltage sensor, and semiconductor switches. The electric machine having phase legs with a corresponding phase winding and resistive path. The first contactor connects the PIM to a positive rail of the bus. The controller opens the first contactor in response to a power-off event, commands a discharge of the capacitor through the resistive paths, diagnoses a state of health (SOH) of the first contactor using a first threshold decay rate of the capacitor output voltage upon opening the first contactor, and executes a control action with respect to the electrical system using the diagnosed SOH. The three possible SOH are unhealthy/hard-welded contactor, unhealthy/soft-welded contactor, and healthy/normally-functioning contactor condition. A vehicle and method are also disclosed.

摘要： Systems and methods for charging multiple rechargeable energy storage systems (“RESSs”) included in one or more vehicles using a single charging system are presented. In some embodiments, a method for charging one or more RESSs may include receiving an indication that one or more charging ports of a plurality of charging ports included in a charging system have RESSs coupled thereto. Based on the indication, a charging map may be generated. One or more charging parameters may be determined based on the generated charging map. Based on the charging parameters, a switching mechanism included in the charging system may be selectively actuated to provide electrical power from a charging power source to charging ports coupled to RESSs.

摘要： Disclosed are control algorithms and system architectures for arbitrating vehicle charging, e.g., for electric vehicles with rechargeable battery packs, wired and wireless charging capabilities, and control logic for governing such charging. A method is disclosed for managing charging of electrical storage units of motor vehicles at vehicle charging stations. The method includes determining if a wireless charging interface of the motor vehicle is available for wireless power transfer, and determining whether or not the vehicle charging station has an electrical connector coupled to a wired charging interface of the motor vehicle. Responsive to the charging station having an electrical connector coupled to the wired charging interface, the method initiates a wired (conductive) charge power mode. Conversely, if the wireless charging interface is available for power transfer and an electrical connector is not coupled to the wired charging interface, the method responsively initiates a wireless (inductive) charge power mode.

摘要： An electrical system connectable to an offboard power supply includes a battery pack, parallel DC-coupled conductive and inductive charging systems, and a controller. The controller initiates charging of the battery pack using analog low-voltage signals. A charging preference may prioritize charging via a designated one of the charging systems. Another electrical system includes a battery pack connected to a DC voltage bus, a charge coupler connectable to the offboard power supply to establish a plug-in charging connection, parallel DC-coupled conductive and inductive charging systems, and a controller. The controller commands charging using the analog low-voltage control signals, doing so via the conductive charging system when the charge coupler is plugged into the power supply and via the wireless charger when the charge coupler is not plugged into the power supply and the controller detects proximity of the system to the primary induction coil.

摘要： An electrical system includes a contactor having a pair of contacts and a coil configured to electrically close and open the contacts. The electrical system also includes a high voltage (“HV”) circuit including a power supply electrically connected to at least one of the contacts of the contactor. The electrical system further includes a low voltage (“LV”) circuit electrically connected to the coil and configured to selectively energize the coil of the contactor. A disconnect mechanism is coupled with the LV electrical circuit and operable to electrically open the LV electrical circuit to actuate electrical opening of the contacts of the contactor.

摘要： A power inverter includes a multi-phase inverter circuit electrically connected to positive and negative conductors of the high-voltage bus. A bi-stable switch is electrically connected in series with a discharge resistor between the positive and negative conductors of the high-voltage bus, and a capacitor is electrically connected between the positive and negative conductors of the high-voltage bus. First and second trigger circuits are in communication with a gate of the bi-stable switch, and first and second contactors are controllable to electrically connect a respective one of the positive and negative conductors of the high-voltage bus to the high-voltage DC power source. The bi-stable switch is controllable to provide a low-impedance electric current flow path through the discharge resistor between the positive and negative conductors of the high-voltage bus in response to an activation signal from one of the first and second high-voltage DC contactor circuits.

摘要： A battery pack with a drain plug and a circuit to detect when a liquid coolant has entered the battery pack. A soluble plug may be disposed within the cavity of the carrier; the soluble plug is configured to at least partially dissolve when fluidly coupled with a coolant allowing a portion of the coolant to flow between the inlet and the outlet and out of the battery pack. A strain gauge cooperative with the carrier such that a measured resistance change in the strain gauge corresponds to the soluble plug in contact with the liquid coolant. An associated circuit with the drain plug provides notification of the activation of the drain plug to the on-board computer systems.

摘要： Systems and methods for switching high-voltage contactors in a battery system with reduced degradation over time are presented. In certain embodiments, a system may include solid-state switches disposed is parallel with the high-voltage contactors. The solid-state switches may be configured to selectively close when the high-voltage contactors are in transition from a closed state to an open state. By closing the solid-state switches during this transition, electrical arcing and associated degradation and/or damage to the contactors may be reduced.

摘要： A delayed charging system for a vehicle implements an energy transfer efficiency check prior to the scheduled charge time to confirm sufficient grid power quality and wireless power quality. In addition to this, a foreign object check is performed prior to the scheduled charge. These checks are performed immediately after the customer sets up the delayed session as well as at specified intervals after that. If a power quality issue is detected, the customer will be alerted so they can remedy the situation.
