摘要： A vehicle power supply system includes a first secondary battery, a second secondary battery whose output voltage is lower than that of the first secondary battery, a power conversion device configured to convert an input AC voltage into a DC voltage and output the DC voltage, a battery pack configured to receive the DC power output from the power conversion device and charge the first secondary battery, DC/DC converters configured to step down an input DC voltage to output the stepped-down DC voltage, and a power control unit configured to control the battery pack. The first secondary battery is connected to input ports of the DC/DC converters via the battery pack. An output port of the DC/DC converter is connected to a video media control unit, and the DC/DC converter is provided separately from the video media control unit. An output port of the DC/DC converter is connected to the second secondary battery.

摘要： A symmetrical DC-to-DC boost converter includes a DC input voltage source with a negative DC voltage input and a positive DC voltage input, a negative DC and positive DC voltage output, at least four switches, and two chokes, one of which is connected to the negative DC voltage input and two adjacent switches, and the other of which is connected to the positive DC voltage input and two other adjacent switches, such that a symmetrical topology with separate DC voltage inputs is obtained. Furthermore, there is an input capacitor between the voltage inputs and a first symmetry capacitor connected to the negative DC voltage input and the negative DC voltage output, as well as a second symmetry capacitor connected to the positive DC voltage input and the positive DC voltage output.

摘要： A method for accurately measuring the impedance of the fuel cell stack in the vehicle during operation of the vehicle includes determining whether measuring the impedance of the fuel cell stack is requested during driving of the vehicle driven by using a power of a fuel cell stack, switching a DC-DC converter connecting the fuel cell stack and a battery to each other to a buck mode when measuring the impedance is requested, thereby blocking output current of the fuel cell stack from flowing to the battery through the DC-DC converter, determining a first current value of the fuel cell stack for measuring the impedance, controlling a resistance value of a COD variable resistor consuming the output current of the fuel cell stack according to the first current value, and measuring the impedance of the fuel cell stack while the output current of the fuel cell stack is maintained at the first current value.
