The battery pack (2) is provided with a network interface (12) given a unique IP address, which is connected to a LAN along with a network interface (11) of a PC body (1). Even if the PC body (1) is suspended, the battery pack (2) can be accessed over the LAN. A computer for maintenance, arranged on the LAN, can thus access the battery back (2) to acquire the operating status of a rechargeable battery (3) and data stored in a memory (8), such as a serial number, thereby performing maintenance.

  • Patent number: 6936374
    Abstract: The battery pack of the invention comprises an outer case, a battery main body disposed within the outer case, and a heat-sensitive current blocking element mounted on the outer surface of the battery main body. On the inner surface of the outer case is provided a press portion for pressing the heat-sensitive current blocking element against the outer surface of the battery main body. In this arrangement, even when the battery pack is given vibration or impact, the heat-sensitive current blocking element can be kept retained in close contact with the outer surface of the battery main body. Accordingly, the heat generated in the battery main body can be rapidly and surely transferred to the heat-sensitive current blocking element, making sure that thermal runaway of the battery is prevented.

  • Patent number: 6929881
    Abstract: A rod-shaped coupler for connecting a current collector to a terminal pin, is described. The coupler is secured to the entire width of the current collector, preferably the cathode in a cell of a case negative design, and is generally aligned along the longitudinal axis of the electrode assembly. An extension portion of the coupler extends beyond the electrode assembly and is of a hollow, tubular structure crimped or otherwise collapsed into surrounding contact with the terminal pin. The coupler and terminal pin are then welded together. Preferably, the terminal pin is roughened prior to effecting the connection. This method of attachment is suitable for either primary lithium or secondary lithium ion cells, particularly those powering implantable biomedical devices.

  • Patent number: 6869708
    Abstract: A small fuel cell (10) powers a portable electronic device (12) and contains a fuel reservoir (14) and a device (16) that measures the amount of liquid fuel (18) that is in the reservoir. The fuel cell operates on hydrogen that is obtained from a liquid hydrocarbon fuel, such as alcohol or other hydrocarbons. The liquid fuel is typically converted into hydrogen by a reforming process. The reservoir that is connected to the fuel cell has an indicia (19) that is readable by a human user of the portable electronic device, for measuring the amount of liquid hydrocarbon fuel that is present in the reservoir. Typically, the indicia consist of a sight glass, a capacitive element, a resistive element, a transparent portion of the reservoir, a float, or an acoustic transmitter coupled with an acoustic receiver.

  • Patent number: 6835491
    Abstract: A multiple-cell battery having a built-in controller is disclosed that extends the run time of the battery. The controller may extend the run time of the battery, for example, by converting the cell voltage to an output voltage that is greater than a cut-off voltage of an electronic device, by converting the cell voltage to an output voltage that is less than the nominal voltage of the electrochemical cell of the battery, or by protecting the electrochemical cell from current peaks. The controller may also include a ground bias circuit that provides a virtual ground so that a converter may operate at lower cell voltages. The battery may be a single-cell battery, a universal single-cell battery, a multiple-cell battery or a multiple-cell hybrid battery. The individual cells of the multiple-cell battery may be connected in series or parallel. In addition, the individual cells may have a controller in each cell that is capable of performing one or more functions to extend the run time of the cell.

  • Publication number: 20040067412
    Abstract: A portable electronic device receives notification from a base station showing that the amount of energy or fuel remaining in a battery is low. The portable electronic device then has a display showing the remaining amount of energy or fuel in the battery is low in accordance with the notification. Location information is received by a location information receiving section, and is transmitted to the base station. The portable electronic device receives fuel supplying device information showing the location of a device able to supply fuel or give a charge of electricity to the battery from the base station. A supplying device provides the fuel or gives the charge of electricity in accordance with information transmitted from the portable electronic device, and transmits information showing the compensation owed to the base station.

  • Publication number: 20040005497
    Abstract: An electronic apparatus has a multiplicity of display units including an electronic viewfinder and a liquid crystal display (LCD) panel. The apparatus has various display modes. The remaining battery power, i.e., estimated amounts of remaining battery times relative to a current remaining battery capacity, are calculated for the respective display modes. The calculated remaining battery power is collectively displayed as the remaining battery power information on the respective display units. The remaining battery power can be obtained for all the display modes even when the battery is being charged, so that a user can always grasp the remaining battery power of any of the display modes.
