Abstract: A system may include an energy provision system, a first converter, a second converter, a traction system, and an auxiliary system. The energy provision system may provide a first voltage. The first converter may increase the first voltage from the energy provision system from the first voltage into at least a second voltage. The traction system of a vehicle may be powered by the second voltage from the first converter. The second converter may decrease the first voltage from the energy provision system from the first voltage to a third voltage which may be less than the second voltage. The auxiliary system of the vehicle may be powered by the third voltage from the second converter that may be less than the second voltage.

Abstract: Methods and systems for providing emergency heating in an electric vehicle (EV) running out of power are described herein. An on-board computer or mobile device in an EV may determine that an amount of charge remaining for powering the EV is below a threshold charge level. The on-board computer or mobile device may then route the remaining amount of charge to power a heating system in the EV to maintain a temperature in the EV above a threshold temperature level, and shut down power to other components within the EV.

Abstract: A device for discharging a high-voltage (“HV”) battery pack in an electrical system having a low-voltage (“LV”) bus and a high-voltage (“HV”) bus includes a resistive load and an electronic control unit (“ECU”). The ECU transmits electronic control signals to the resistive load to change an output state of the resistive load. As part of a related method, the ECU receives a state of charge (“SOC”) of the battery pack and an auxiliary voltage level of the LV bus. The ECU then selectively adjusts the electronic control signals in response to the SOC and auxiliary voltage level to optimize the output state of the resistive load. This continues until the SOC is within a specified SOC range.

Abstract: Methods, devices, and systems are described for charge port defrosters. The system includes a charge port integrated into a vehicle and configured to power the vehicle, a charge port cover coupled to the hinge and configured to cover the charge port, a heating element located proximate to the charge port and the charge port cover, and a controller. The controller is configured to determine whether the vehicle is in an environment capable of satisfying a temperature threshold. The temperature threshold is indicative of cold weather conditions. The controller is configured to operate the heating element to be powered in response to determining the vehicle is in the environment capable of satisfying the temperature threshold.

Abstract: A solar charging system mounted on a vehicle includes a power generation module using a solar panel, an auxiliary system including an auxiliary machine battery for storing electric power generated by the power generation module and an auxiliary machine load to which electric power is supplied from the auxiliary machine battery, a high-voltage battery used for driving the vehicle, and a control unit provided between the high-voltage battery and the auxiliary system and controlling power transfer between the high-voltage battery and the auxiliary system. In a case where power transfer from the high-voltage battery to the auxiliary system is requested, when the power generated by the power generation module is not supplied to the auxiliary system, the control unit supplies power of the high-voltage battery to the auxiliary system.

Abstract: A through the road (TTR) hybridization strategy is proposed to facilitate introduction of hybrid electric vehicle technology in a significant portion of current and expected trucking fleets. In some cases, the technologies can be retrofitted onto an existing vehicle (e.g., a trailer, a tractor-trailer configuration, etc.). In some cases, the technologies can be built into new vehicles. In some cases, one vehicle may be built or retrofitted to operate in tandem with another and provide the hybridization benefits contemplated herein. By supplementing motive forces delivered through a primary drivetrain and fuel-fed engine with supplemental torque delivered at one or more electrically-powered drive axles, improvements in overall fuel efficiency and performance may be delivered, typically without significant redesign of existing components and systems that have been proven in the trucking industry.
