Abstract: A preemptive optimization of a power distribution event associated with providing an electrical power from a battery onboard a vehicle to a charging station offboard the vehicle. The preemptive optimization may include preemptively charging the battery in advance of the power distribution event and/or preemptively configuring the vehicle and the battery, such as with establishment of standby session, to provide electrical power from the battery to the charging station without providing the electrical power to the charging station until the charging station thereafter experiences an outage, interrupt, etc.

Abstract: A high-voltage battery assembly includes a high-voltage battery electrically connected to a high-voltage bus including a positive rail and a negative rail, wherein the negative rail includes a controllable contactor switch. A boost charging module includes a DC-DC boost converter, a low-voltage power input line, a boost switch and a boost controller. The DC-DC boost converter is electrically connected to the low-voltage power input line via activation of the boost switch. The DC-DC boost converter connects to the positive rail. A low-voltage electrical connector is electrically connected to the low-voltage power input line of the DC-DC boost converter. The boost controller detects low-voltage power from the low-voltage electrical connector, detects that the controllable contactor switch, closes the boost switch, and controls the DC-DC boost converter to convert the low-voltage power on the low-voltage power input line to high-voltage power to charge the high-voltage battery.

Abstract: A method for responding to energy expenditure events includes providing electric energy from an external source to a vehicle energy storage component until the energy storage component is charged to a threshold state of charge percentage. An external data source is monitored using a controller for an occurrence of an energy expenditure event in at least one connected system. The controller responds to the occurrence of the energy expenditure event by charging a remainder of the vehicle energy storage component.

Abstract: A charging box performs a direct current fast charging (DCFC) session of a recipient by a donor, e.g., during a vehicle-to-vehicle (V2V) charging session, and includes a portable housing, disconnect devices connected to a high-voltage (HV) bus to connect/disconnect respective inlet and outlet charging ports to/from the bus, and multiple direct current-to-direct current (DC-DC) converters. A high-voltage-to-high-voltage (HV-HV) converter is connected to the bus. An optional high-voltage-to-low-voltage (HV-LV) converter may be connected to the HV-HV converter. An optional low-voltage (LV) energy storage device is connected to the housing and HV-LV converter. A communication processing unit (CPU) establishes two-way communication between the donor and recipient. A system controller selectively pre-charges the bus, recharge the energy storage device, and selectively command offloading of a DC charging current from the donor, through the HV-HV converter, and to the recipient.

Abstract: An inverter power module: selectively applies power from a battery to a permanent magnet (PM) electric motor; and selectively provides power output by the PM electric motor for the battery. A switch, when open, prevents power flow the inverter power module from the battery, and, when closed, enables power flow between the inverter power module and the battery. An adjustment module determines an SOC adjustment based on at least one of a vehicle speed and a temperature of the battery. A maximum module receives a first maximum SOC of the battery and that determines a second maximum SOC of the battery based on the first maximum SOC and the SOC adjustment. A clutch control module disengages a clutch, decoupling the PM electric motor from a transmission, when the switch is stuck closed and an SOC of the battery is greater than the second maximum SOC.

Abstract: A method for coordinating a discharge session in which direct current power is offloaded from a power supply, e.g., of an electric vehicle (EV), to a bidirectional offboard charging station includes, in response to connection of the power supply to the charging station via a charging cord set, exchanging charging data between the EV and charging station. This occurs over a low-voltage communication line, with charging data including power and current limits of the EV and charging station. In response to the limits being indicative of negative limits, with the negative limits representing a request for the discharge session, the method includes transmitting the EV power and current limits to the charging station to confirm the request. The discharge session is initiated in response to confirming the request through an exchange of a unique identifier indicating support for the discharge session.

Abstract: A method of prioritizing power output of first and second power-sources in a vehicle includes identifying, via a controller communicating with a satellite, the vehicle's position on a specific road course. The method also includes receiving a request for total amount of power from both power-sources and determining first power-source power and available second power-source target maximum power based on the vehicle position. The method also includes determining, based on the vehicle position, a minimum energy reserve of a source configured to energize the second power-source and available second power-source power based on the determined reserve. The method also includes subtracting the first power-source power from the requested total amount of power to determine a requested second power-source power. Furthermore, the method includes comparing the available and the requested second power-source power and generating the smaller power value to minimize the time for the vehicle to traverse the road course.

Abstract: A high-voltage battery assembly includes a high-voltage battery electrically connected to a high-voltage bus including a positive rail and a negative rail, wherein the negative rail includes a controllable contactor switch. A boost charging module includes a DC-DC boost converter, a low-voltage power input line, a boost switch and a boost controller. The DC-DC boost converter is electrically connected to the low-voltage power input line via activation of the boost switch. The DC-DC boost converter connects to the positive rail. A low-voltage electrical connector is electrically connected to the low-voltage power input line of the DC-DC boost converter. The boost controller detects low-voltage power from the low-voltage electrical connector, detects that the controllable contactor switch, closes the boost switch, and controls the DC-DC boost converter to convert the low-voltage power on the low-voltage power input line to high-voltage power to charge the high-voltage battery.
