Abstract: Provided is a vehicular power source unit having an external electric power supply controlling element (94) configured to control the operation of a heater (16) and a recharger (22) operated by an electric power supplied from a commercial power source (70) via an external power source connector (25) according to a terminal voltage and temperature of a fuel cell (10) detected by a fuel cell state detecting element (91) and a state of a battery (20) detected by a battery state detecting element (92) when a fuel cell vehicle is halted, the supply of reactant gas to the fuel cell (10) by a fuel cell controlling element (93) is stopped and the external power source connector (25) is connected to the commercial power source (70).

Abstract: A hydrogen filling apparatus fills a hydrogen tank, for example, mounted on a fuel cell vehicle with hydrogen stored in a hydrogen storage tank. After the hydrogen tank has started to be filled with hydrogen in a hydrogen filling process, the hydrogen filling process is stopped for a predetermined time, and a temperature and a pressure in the hydrogen tank are detected while the hydrogen filling process is being stopped. Thereafter, a time needed to fill the hydrogen tank with a predetermined amount of hydrogen is calculated based on detected values of the temperature and the pressure, and the calculated time is displayed on a display unit.

Abstract: In an apparatus for heating a battery of a vehicle, having an electric rotating machine and buck-boost converter between the battery and rotating machine to step up/down voltage outputted from the battery to be supplied to the rotating machine and step up/down voltage generated by the rotating machine to be supplied to the battery, it is configured to have a first capacitor interposed between wires connecting the battery to the converter, a second capacitor interposed between wires connecting the converter to the rotating machine, and a heating controller to control operation of the converter to generate current similar to rectangular wave current and input/output the current between the battery and the second capacitor through the first capacitor so as to heat the battery. With this, it becomes possible to efficiently heat the battery so that the battery can output expected power, without adversely affecting the size of the apparatus.
