A power supply device used for a wheel rim is mounted on a wheel rim of a vehicle. The power supply device includes a magnetism assembly, an axle member, a magnet, a weight block, a seat, a coil module, and a control module. The seat is disposed on the wheel rim. One side of the seat is provided with an axle seat for connection of the axle member. The seat is driven by the wheel rim to turn relative to the magnetism assembly. When the seat is turned to generate power through the magnet and the coil module, the control module selectively transmits the power to a light-emitting device provided on the wheel rim.

Disclosed is a power-generating backlit trim strip for a vehicle, comprising an oscillation system (3, 4; 3, 14), an induction unit (2), a sensor (17) and a control unit (8). The oscillation system (3, 4; 3, 14) includes a movably arranged gyrating mass (3), and the induction unit (2) is used for inductively converting kinetic energy of the gyrating mass (3) into electricity. The sensor (17) is used for determining a frequency of the vehicle vibrations, and the control unit (8) is used for adjusting the resonant frequency of the oscillation system (3, 4; 3, 14) to a determined frequency of the vehicle vibrations.

Charge efficiency of normal charge is improved without restricting an operation of a low-voltage load of an electric vehicle during the normal charge. During a charge of a high-voltage battery of a vehicle, when a determination of the normal charge is made, and when a determination that a mode switching target load is not operated is made, power saving mode transition processing is performed. Therefore, an operating mode of a DC-DC converter, which steps down a voltage at the high-voltage battery and supplies the stepped-down voltage to a low-voltage battery and a low-voltage load, is set to a power saving mode in which consumption power is reduced compared with a normal mode. When a determination that a start-up manipulation of the mode switching target load is performed is made, the operating mode of the DC-DC converter is changed to the normal mode.

An onboard charging system for an electric vehicle is configured to communicate with a power supply through exchange of control signals on a power supply line by modulating a charging current being supplied to the charging system. The charging system is capable of communicating fault and battery parameter data to the power supply, as well as a requested charging current used to regulate the power supply output. The power supply may convert high voltage AC power into a controllable DC output supplied directly to the electric vehicle, thereby providing a convenient means for the vehicle to initiate charging during operations. Connection between the electric vehicle and the power supply may be effected using an extendible and retractable electrical connection, such as a mechanical pantograph.
