A method and a voltage converter assembly for supplying energy to at least one electrical vehicle module. The assembly includes at least one voltage converter that is designed to convert an input voltage, provided by at least one supply source, into at least one predefinable output voltage, which is applied to the at least one vehicle module, a voltage monitor that is designed to detect the input voltage, and an evaluation and control unit that is designed to carry out the method for supplying energy to at least one electrical vehicle module. The supply source is loaded with a predefinable current level when the input voltage that is present exceeds a predefinable setpoint voltage value, the input voltage being converted into at least one output voltage if the input voltage remains above the predefinable setpoint voltage value despite the load on the supply source.

The present disclosure provides a method including determining an operational mode of a vehicle based on data accumulated from at least one vehicle information system associated with the vehicle; selecting one of a plurality of power consumption profiles for the vehicle based on the determined operational mode; and applying the selected one of the power consumption profiles to the vehicle.

A high-voltage line for motor-vehicle high voltage includes an interior tube surrounding an interior cavity of the high-voltage line, an electrically conducting interior conductor surrounding the interior tube, an intermediate insulation surrounding the interior conductor, an electrically conducting outer conductor surrounding the intermediate insulation, and an outer insulation surrounding the outer conductor. The outer insulation, the outer conductor, the intermediate insulation, the interior conductor, and the interior tube are disposed coaxial to one another.

A shortening of an initial diagnosis time is achieved, even after an elapse of a predetermined delay time from an ignition switch being switched to an off-state. After the ignition switch is switched to an off-state after an operation of a control device, which drives an electric motor that applies steering assistance force to a steering system, diagnosis of a power supply circuit that supplies power to the control device is carried out, and a diagnosis item to be implemented in a succeeding initial diagnosis is determined based on a result of the diagnosis.

There are provided a system and a method for controlling power of a high speed vehicle. The system for controlling power of a vehicle includes: a latch relay configured to supply power to a vehicle load or to block power to the vehicle; a communication part configured to output a driving signal when a wakeup signal is received; a pulse generator configured to output a one shot pulse that turns on the latch relay when the driving signal is applied; and a processor configured to control a driving of the latch relay turned on by the one shot pulse when being initialized.

A wire harness includes a linear trunk line section formed by bundling a plurality of power supply lines serving as linear wiring bodies wired in a vehicle and a pair of trunk line end distributors each of which is connected to a corresponding one of both ends of the linear trunk line section and distributes electric power from a power supply mounted on the vehicle to each connected appliance, the power supply being connected to at least one end of each of the trunk line end distributors. Thus, with the wire harness, a wiring path can be simplified by combining the linear trunk line section and the pair of trunk line end distributors.
