A vehicle includes a traveling motor, a traveling battery that drives at least one wheel, a low-voltage electric component, at least one processor, and a storage medium. The traveling battery includes battery modules each including battery cells and supplies electric power to the traveling motor. The low-voltage electric component operates at a voltage lower than an output voltage of the traveling battery. The storage medium stores a program to be executed by the processor. The program includes at least one command that causes the processor to perform a state-of-health (SOH) calculation process of calculating the SOH of the battery modules, and a selection process of selecting a low-voltage power feeder module from the battery modules based on the SOH calculated in the SOH calculation process. The low-voltage power feeder module corresponds to one of the battery modules to be used to supply electric power to the low-voltage electric component.

A low select module is operatively connected to receive input from the external input system and form the protection function module and to output the lower of input from the protection function module and external input system to the thermal engine, the electric motor, and the propeller.

A heat exchange system includes a first thermal circuit, a second thermal circuit, and a controller. A first thermal circuit includes a first device, a first pump, and a first flow path and a second flow path configured to cool the first device. A second thermal circuit includes a second device, a second pump, and a third flow path and a fourth flow path configured to cool the second device. A controller is configured to switch, when the controller switches a flow path of the first thermal circuit from the first flow path to the second flow path and switches a flow path of the second thermal circuit from the fourth flow path to the third flow path, the fourth flow path to the third flow path and the first flow path to the second flow path.

Vehicles may be composed of a relatively few number of “modules” that are assembled together during a final assembly process. An example vehicle may include a body module, a first drive module coupled to a first end of the body module, and a second drive module coupled to a second end of the body module. One or both of the drive modules may include a pair of wheels, a battery, an electric drive motor, and/or a heating ventilation and air conditioning (HVAC) system. One or both of the drive modules may also include a crash structure to absorb impacts. If a component of a drive module fails or is damaged, the drive module can be quickly and easily replaced with a new drive module, minimizing vehicle down time.

A vehicle drive apparatus includes: an engine; a rotary machine; an output member coupled to a drive wheel of a vehicle; a differential mechanism configured to couple the engine, the rotary machine, and the output member together to be differentially rotatable via a plurality of differentially rotatable rotational elements; and an elastic member configured to couple a rotation shaft of the rotary machine to the rotational element of the differential mechanism to be relatively rotatable.

A power source system includes a first power source, a second power source, a Direct Current to Direct Current converter, a first load including a vehicle control device configured to perform predetermined control regarding at least one of traveling, steering, and braking of the vehicle regardless of a driving operation performed by a driver of the vehicle, and an electric actuator as a control target of the vehicle control device, and connected to the first path so as to be supplied with power from the first power source, and a power source control device configured to control an operation of the Direct Current to Direct Current converter such that power is supplied to the first path from the second power source in a case where the predetermined control is performed.

A method for assisting with the positioning of a motor vehicle for inductive charging of a battery of the motor vehicle comprises reading a number plate associated with the motor vehicle using the number plate information to produce a location on the vehicle of a vehicle inductive coupling point (VICP) with reference to at least one reference point on the motor vehicle, comparing a predicted current position of the VICP to a fixed inductive coupling point (ICP) located in or on a road surface upon which the motor vehicle is to be positioned, and providing feedback to one of the driver and the motor vehicle indicative of the required action required to produce alignment of the VICP with the ICP. The method may further comprise energizing the ICP to charge the battery of the motor vehicle when the VICP is predicted to be aligned with the ICP.

Embodiments of the present invention provide a method of controlling a high-voltage circuit (15) of a vehicle, comprising detecting (310) a fault associated with the high-voltage circuit, reducing (320) a voltage of the high-voltage circuit (15) in dependence on detecting the fault, receiving (330) a torque request and, in dependence thereon, increasing (340) the voltage of the high-voltage circuit (15).

An energy supply system, which is a system constituting a regional power system in a target region, includes a power transmission system including a first power generation facility and a second power generation facility, a power transmission and distribution system that supplies power to each consumer, a management system, and an unmanned flying object. The unmanned flying object has a transport function of transporting a cargo and a power supply function of supplying power to an outside. When the amount of power supplied by the power transmission system is less than the amount of power required by the power transmission and distribution system, the management system performs a power adjustment process of supplying power from the unmanned flying object to the power transmission and distribution system by using the power supply function of the unmanned flying object.

A control device of a multi-phase converter having N converter circuits connected in parallel includes: a determination unit configured to determine each share ratio of the N converter circuits to unevenly share input current to the multi-phase converter among the N converter circuits such that a conversion efficiency indicating a ratio of output power from the multi-phase converter with respect to input power to the multi-phase converter is higher in the case where the input current is unevenly shared by the N converter circuits compared to the case where the input current is evenly shared by the N converter circuits when the number of driven converter circuits is one or more and N−1 or less and the start condition is satisfied; and a diagnosis unit configured to diagnose an abnormality of the N converter circuits when the N converter circuits are driven in accordance with the determined share ratios.
