An electrical system can include a rechargeable energy storage system (RESS) and a power inverter connected to the RESS. The power inverter can be configured to provide electrical power to a traction motor. The electrical system includes a plurality of machine windings connected between a plurality of first switches and the traction motor. Each switch of the plurality of first switches is configured to transition between a closed state to allow current flow between the power inverter and the traction motor. The electrical system includes a plurality of inductor windings connected between a plurality of second switches and an off-board power source. Each switch of the plurality of second switches is configured to transition between a closed state to allow current flow between the off-board power source and the power inverter to charge the RESS.

A vehicle includes a charging port for connection to a charging cable capable of delivering electricity to the vehicle, and an ultra-wide band (UWB) transceiver module. The UWB transceiver module includes a master node and at least three antenna nodes. The at least three antenna nodes are deployed at correspondingly diverse locations in the vehicle at fixed distances from the charging port. The master node is configured to determine a position of an UWB antenna or tag external to the vehicle relative to the locations of the at least three antenna nodes and the charging port.

Systems and methods may coordinate and provide bidirectional energy transfer events between electrified vehicles and other devices or structures, such as for supporting transient loads associated with the devices/structures. Battery life information and driving habit information may be leveraged for selecting an appropriate energy transfer strategy for any given vehicle, traction battery pack, structure, and/or grid power source condition. The proposed systems/methods may thereby align grid demand charge strategies to each vehicle's battery life, thereby preserving the life/warranty and asset utilization of the traction battery pack over the entire usage life of the vehicle.

A vehicle includes control pilot circuitry connected with a charge port and including a control pilot line, a resistor, and a switch that selectively connects the resistor between the control pilot line and a ground of electric vehicle supply equipment plugged into the charge port. The vehicle also includes a controller that toggles the switch between open and closed states after receiving an off-board request defining a number of toggles for the switch.

A system and method for managing vehicle charging stations such that when at least two of a plurality of electric vehicle charging stations (also known as electric vehicle service equipment, or EVSE) occupied with vehicles awaiting a charge, the present system manages the charging of individual vehicles in cases where the aggregated demand for charging exceeds the capacity of the circuits supplying the plurality of EVSE. By cycling so that only a few of the vehicles are charging at a time, the demand on the circuits is kept below a predetermined limit. In cases where a load shedding event is in progress, the limit can be further reduced. In cases where the cost of electricity is varying dynamically, the system considers a driver's explicit charging requirements (if any) and preferences for opportunistic charging when the price of electricity is not too high.

A computer-implemented method for increasing safety during charging of a vehicle battery of a vehicle by a charging station, the method comprising the steps of calculating a forecast value for a maximum safe charging current by the controller of the vehicle based on sensor data generated by sensors of the vehicle and adjusting the charging current provided by the charging station in response to the forecast value of a maximum safe charging current.
