The disclosure relates to a control method for a vehicle-mounted wireless charger, a vehicle-mounted wireless charger, and a vehicle. The vehicle-mounted wireless charger has a fan, and the control method includes: establishing a functional relationship between a vehicle speed of a vehicle and a duty cycle of the fan; detecting a real-time vehicle speed of the vehicle when the wireless charger charges a device to be charged and the fan is turned on; and determining and adjusting the duty cycle of the fan based on the real-time vehicle speed and the functional relationship, to control noise of the vehicle-mounted wireless charger. The vehicle of the disclosure may effectively control the noise of the vehicle-mounted wireless charger using the control method, thereby improving the NVH performance of the vehicle and driving experience of a user.

A mobile platform comprising: (a) one or more platforms to support one or more cartridges, (b) one or more compartments within the one or more platforms, (c) one or more vertical supports connected to the one or more platforms, (d) a plurality of wheels connected to a bottom of the one or more platforms, and (e) one or more recesses located in the one or more platforms to receive one or more support accessories, wherein the one or more compartments are shaped to receive the one or more cartridges so that the one or more cartridges are secured to the one or more platforms during movement.

The present invention relates to a motor vehicle that is equipped with an electrical door closing mechanism, a radio-based signal receiver and a control unit, wherein the door closing mechanism can be actuated after receiving and verifying an access authorization code by electrical signals that are generated by a control unit. The motor vehicle possesses an electrical charging apparatus accessible from the outside so that a signal generator that is provided to generate the access code can be charged from the electrical system of the motor vehicle in the event of an insufficient charge. Furthermore, the invention describes a method for charging a signal generator that can be executed using the device according to the invention.

A movable power generating system for a vehicle may include an inverter for receiving power from a battery in a vehicle to generate AC power, a motor for receiving the AC power from the inverter, a switch block connected to the output terminal of the inverter and for branching the AC power, and an external power supply unit connected to the switch block and for outputting the AC power.

A discharging control system of a vehicle that supplies power to a load device outside the vehicle via a power cable, includes a connection signal line, a detector, and a controller. The connection signal line is configured such that a potential thereof changes in response to a discharging connector provided on the power cable being connected to the vehicle. The detector is configured to detect the potential of the connection signal line. The controller is configured to control a physical quantity related to the power supplied from the vehicle to the load device, based on the potential detected by the detector.

A powertrain system includes an electric generator, a compressor, a water cooling module including a water pump, an electronic fan, a steering pump, a pneumatic module including an air pump, a transmission device, and an electric motor. The electric motor is configured to drive the electric generator, the compressor, the water pump, the electronic fan, the steering pump, and the air pump to work through the transmission device. The present invention further provides an electric vehicle with the powertrain system.

A safety apparatus for portable power generation of a fuel cell vehicle and an operation method thereof are provided. The safety apparatus includes a fuel cell that supplies power required for driving a motor of the fuel cell vehicle and a battery used as an auxiliary power source of the fuel cell. A bidirectional power converter adjusts input power and output power of the battery. A connection port connects to a portable power generator positioned extraneous to the fuel cell vehicle and a relay is connected to the connection port to adjust supplying of power to the portable power generator. A fuel cell controller determines whether a vehicle state satisfies a portable power generation mode entering condition when start-up of the fuel cell vehicle is turned on and operates the relay based on a confirmation result to perform portable power generation.
