A charging control unit decides the number of battery cells on the basis of an output voltage of a battery pack, and an output voltage of a charging circuit is determined in accordance with the decided number of battery cells. Even though supply of an external power supply is detected, when a battery connection is not detected, the power supply circuit of the charging control unit is set in a stop state. In addition, when disconnection of the battery is detected, a canceling voltage for canceling a cutoff state caused by overdischarging of the battery is output. In a power supply device for a portable terminal, a capacitor electrically charged by an output voltage of main DC / DC converter is connected as an auxiliary power supply of a backup DC / DC converter to make exchange of the auxiliary battery unnecessary.

A main-remote radio base station system includes plural remote radio units. Fiber costs are significantly reduced using a single optical fiber that communicates information between the main unit and the remote units connected in a series configuration. Information from the main unit is sent over a first fiber path to the remote units so that the same information is transmitted over the radio interface by the remote units at substantially the same time. The main unit receives the same information from each of the remote units over a second fiber path at substantially the same time. Delay associated with each remote unit is compensated for by advancing a time when information is sent to each remote unit. A data distribution approach over a single fiber avoids the expense of separate fiber couplings between the main unit and each RRU. That approach also avoids the expense of WDM technology including lasers, filters, and OADMs as well as the logistical overhead needed to keep track of different wavelength dependent devices.

Communication is provided for each of battery ECUs so that the battery ECUs are connected through a connection cable to communicate with each other. Operating power is constantly supplied to the battery ECU used as a master while being supplied to the battery ECUs used as slaves through a relay contact. When a vehicle stops running, the master battery ECU controls the relay contact to be turned OFF after collecting necessary data of each of the slave battery ECUs to store therein. When the vehicle restarts running, the master battery ECU turns the relay contact ON to transmit the necessary data to each of the slave battery ECUs.

A supercharger of an engine comprises a motor / generator, a compressor provided in an air intake system of the engine, and a planetary gear mechanism. The planetary gear mechanism includes a sun gear connected to a driving shaft of the engine, planetary gears connected to the motor / generator and a ring gear connected to the compressor. The controller drives the motor / generator to control a rotational speed of the planetary gears. Through the control of the rotational speed of the planetary gears, a rotational speed of the compressor is controlled independently of a rotational speed of the engine. Thus, the rotation speed of the compressor can be continuously changed over a range from zero to a higher rotational speed than the engine rotational speed. Any desired supercharged pressure can be generated independently of the engine rotational speed.
